To determine where to insert “G” clips, locate the top of a universal mounting hole pattern on the left mounting rail. In the universal rail pattern, the spacing between holes is 1/2 inch, 5/8 inch, 5/8 inch, and 1/2 inch. To find the top of the pattern, locate the midpoint between any two holes that are spaced half an inch apart. Figure 2 shows the universal mounting hole pattern. Distribution Rack Installation 27 Top of a universal mounting hole pattern 1/2-inch spacing Universal mounting hole pattern 5/8-inch spacing 5/8-inch spacing 1/2-inch spacing Figure 2 Universal Mounting Hole Pattern 4 From the top of the universal mounting hole pattern, insert “G” clips in the holes designated for the unit model. 5 Repeat steps 3 and 4 for the right rail. Ensure that you start on the same hole space. You are now ready to mount the CoreBuilder 7000 family ATM switch into the distribution rack. 28 CHAPTER 3: INSTALLING A COREBUILDER 7000 FAMILY ATM SWITCH Mounting the CoreBuilder 7000 Family ATM Switch Once the distribution rack is ready, you can mount the CoreBuilder 7000 family ATM switch into the rack. To mount the CoreBuilder 7000 family ATM switch into the distribution rack: 1 Carefully lift the CoreBuilder 7000 family ATM switch into place, aligning the mounting brackets to the holes you have designated for mounting. A fully-configured CoreBuilder 7000 family ATM switch weighs 43 pounds as shipped. To avoid personal injury, do not lift the unit without assistance. 2 While holding the CoreBuilder 7000 family ATM switch in place, firmly insert the mounting screws (10/32 x 1/2 Phillips) into the mounting holes on both sides of the rack. The unit is now installed in the distribution rack. To insert the power supply, switching modules, and interface cards, configure optical ports for the interface modules and connect network cabling and power to the unit see Chapter 4. 4 INSTALLING AND CONNECTING COREBUILDER MODULES This chapter describes how to install and replace the CoreBuilder® 7000 family modules. The following modules are covered. ■ Power Supply Module ■ Switch Module ■ 4-Port Interface Module ■ Fan Tray ■ Connecting to Network Devices The installation procedures of the other modules of the CoreBuilder 7000 family modules are described in their respective guides. This chapter also describes how to connect the CoreBuilder 7000 family ATM switch to network devices. Safety Precautions When handling replacement parts, 3Com recommends that you always use a wrist strap connected to a proper ground. This helps prevent the module from being damaged by electrostatic discharge. Additionally, when not in use, the module should be stored in an antistatic bag. If the system is powered on when you are replacing a module, do not insert any metal objects, such as a screwdriver or a finger with jewelry, in the open slot. This could cause burns or other bodily harm, as well as system damage. 30 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES Vorsichtsmaßnahm en Wenn Sie Ersatzteile handhaben, benutzen Sie immer ein Band am Handgelenk, daß gut geerdet ist. Das hilft vermeiden, daß das Ersatzteil durch elektrostatische Entladung beschädigt wird. Darüber hinaus sollte ein Modul, wenn nicht benutzt, in einem antistatischen Beutel aufbewahrt werden. Steht das System unter Strom, wenn sie ein Modul installieren oder auswechseln, führen Sie keine Metallgegenstände, wie einen Schraubenzieher oder einen Finger mit Schmuck in den offenen Schlitz ein. Das könnte zu Verbrennungen oder anderen Körperschäden führen, sowie auch zu Schäden am System. Mesures de sécurité Lors de la manipulation des pièces de rechange, 3Com recommande de toujours utiliser une bande attachée au poignet et reliée à la terre. Cela aidera à éviter que la pièce ne soit endommagée par une décharge électrostatique. De plus, lorsqu'il n'est pas utilisé, le module doit être conservé dans un emballage antistatique. Si le système est alimenté lors de l'installation ou du remplacement d'un module, ne jamais insérer d'objet métallique tel qu'un tourne-vis ou un doigt portant un bijou dans la fente. Cela est susceptible de provoquer brûlures ou autres dommages corporels, et d'endommager le système. Power Supply Module The CoreBuilder 7000 family ATM switch provides a dual load-sharing power supply capability where the second unit can serve as a redundant power supply. For more information, see “Redundant Power Supply” on page 85. For certain combinations of installed interface cards, the second power supply cannot be used as a redundant supply (see “Providing Redundancy for Various Power Loads” on page 90). This section discusses the following topics: ■ Installing a Power Supply Module ■ Replacing a Redundant Power Supply Module Power Supply Module Installing a Power Supply Module 31 To install a power supply module: 1 Orient the module so that its sides enter the guides on either side of the chassis slot. 2 Slide the module into the chassis until the face panel is flush with the enclosure. 3 Secure the screws on either side of the front panel. 4 If a redundant power supply is not installed in the second power supply slot, cover the slot with a blank panel for safety. Replacing a Redundant Power Supply Module You can replace the redundant power supply without having to turn off the system (hot-swap). For more information on the operation of the redundant power supply module, see “Redundant Power Supply” on page 85. To replace a redundant power supply module: 1 Disconnect the power cord from the power supply. 2 Loosen the screws at the extreme right and left of the power supply, near the handles (see Figure 3). 3 Grasp the handles of the redundant power supply you want to replace and pull them outward. This ejects the power supply. 4 Remove the new power supply from its antistatic bag. Place the old power supply in the antistatic bag and set it aside in a safe place. 5 Orient the power supply so its labelling is upright. 6 Insert the power supply into the chassis by placing it between the guides of the slot and sliding it until it stops. 7 Tighten the power supply’s securing screws. 8 Connect the power cord to the power supply. 32 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES Figure 3 Hot-Swapping a Redundant Power Supply Switch Module The CoreBuilder 7000 family ATM switch provides for a redundant switch module to ensure continued operation should the main switch module fail. For more information on the operation of the redundant switch module, see Chapter 10 in the Operations Guide. This section includes the following topics: Installing a Switch Module ■ Installing a Switch Module ■ Replacing a Switch Module ■ Setting up Switch Module Redundancy ■ Setting up Switch Module Hardware Redundancy ■ Setting up Hardware Redundancy and LANE Redundancy To install a switch module in the CoreBuilder 7000 family ATM switch chassis: 1 Remove the new card from its antistatic bag. 2 Orient the card so its labelling is upright and make sure the inject handles are in the outward position. Switch Module 33 3 Insert the card into the chassis by placing it between the guides of the selected slot and sliding the card until it stops. 4 Grab both inject handles and push them inward. This locks the card into the chassis. You may have to apply considerable pressure to the handles. An audible “click” indicates that the connectors have engaged. 5 Tighten the card’s securing screws. You are now ready to connect cables to the appropriate ports. Replacing a Switch Module To hot-swap the switch module: 1 Disconnect the cables from the card's ports. Ensure that there is a record of where the cables are attached so that you can correctly re-connect them to the new card. 2 Loosen the screws at the extreme right and left of the card, near the insert/eject handles. 3 Grasp the insert/eject handles of the card you want to replace and push them outward. This ejects the card. You may have to apply considerable force to the handles. You will hear a “click” to indicate that the connections have separated, and the card will slide slightly forward out of the CoreBuilder chassis. 4 Remove the new card from its antistatic bag. Place the old card in the antistatic bag and set it aside in a safe place. 5 Orient the card so its labelling is upright and make sure the inject handles are in the outward position. 6 Insert the card into the chassis by placing it between the guides of the selected slot and sliding the card until it stops. 7 Grab both inject handles and push them inward. This locks the card into the chassis. You may have to apply considerable pressure to the handles. An audible “click” indicates that the connectors have engaged. Verify that the card has been properly installed by observing its LEDs. 8 Tighten the card’s securing screws. 9 Connect cables to the appropriate ports. 34 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES Figure 4 Hot-Swapping a Switch Module or Interface Module Setting up Switch Module Redundancy This section describes procedures for installing and setting up both a main and redundant switch module together. Two different setup procedures are described. The first procedure covers setting up the main and redundant switch module hardware redundancy without setting up LANE redundancy. This procedure only requires operating the LMA. The second procedure sets up the main and redundant switch module hardware redundancy as well as LANE redundancy. It requires both the LMA and the Transcend Enterprise Manager. There are two situations where you would use the procedures of this section: 1 The initial installation of main and redundant cards. 2 The main card in the first slot has failed and the redundant card in the second slot has taken over as the main card. The failed card in the first slot has been replaced by a new card and this new card is now the redundant one. Switch Module Setting up Switch Module Hardware Redundancy 35 Use the following procedure to set up the switch module hardware redundancy. 1 Designate and mark the main and redundant switch modules. 2 Insert the switch module you marked as “redundant” in slot 2. Do not insert the switch module you marked as “main” yet. 3 Turn on the CoreBuilder 7000 family ATM switch. The switch module in slot 2 becomes active. 4 Run the Integrated Fast Setup procedure (see “Integrated Fast Setup” on page 56.) using the LMA command (9) FST 5 Insert the main switch module in slot 1. 6 Reboot the CoreBuilder 7000 family ATM switch using the LMA menu sequence: (1) SYS / (7) RBO. The switch module in slot 1 becomes active. 7 Verify main and redundant switch module status using the LMA command: (1) SYS / (4) SWM You should see the following display. Slot id Slot status ------- 1 2 Switch type ----------- Occupied Occupied Switch mode ---------------- 16x16 ATM switch 16x16 ATM switch Memory size ------------ Active Redundant ----------- 8M 8M 8 Run the Integrated Fast Setup procedure using the LMA command (9) FST to verify the configuration in the main switch module. The switch is now operational. Setting up Hardware Redundancy and LANE Redundancy This section presents a procedure for setting up both switch module hardware redundancy and LANE redundancy in the same session. Both the LMA and the Transcend Enterprise Manager are used. 36 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES General Description of the Procedure The following is a general description of the procedure for orientation purposes only. When you perform the procedure, use the detailed steps in the following sections. 1 Install both switches in chassis and run CFGFRMAT.BAT on each one. Connect Ethernet ports of each switch module and install at least one interface card in the chassis. 2 Configure the first switch using the Integrated Fast Setup of the LMA and do not reboot the switch in the Integrated Fast Setup. 3 Reboot the switch after one minute using the LMA menu. 4 Answer “no” to the prompt “Erase the setup parameters?” and use the LMA to check that all configuration parameters (i.e., database, IP, NNI etc.) have passed successfully to the second switch module. 5 Configure LANE redundancy in the first switch using the Transcend Backbone and Services Setup window and close the window when finished. 6 Reboot the switch after one minute 7 Configure LANE redundancy in the second switch module using the Transcend Backbone and Services Setup window and close the window when finished. 8 After one minute use the MIB browser to check the LECS order list and the Backbone and Services Setup window to check the LECS database. 9 Reboot the box. 10 Check the second switch using the MIB browser to check the LECS order list and the Backbone and Services Setup window to check the LECS database. Preparatory Steps Carry out the following preparatory steps. 1 Install main and redundant switch modules in the switch module slot 1 and slot 2 respectively (see“Installing a Switch Module” on page 32). Do not run the Integrated Fast Setup yet. Each time the switch is rebooted during this procedure the cards change roles. The main card becomes the redundant card and vice versa. The main card can always be identified by its ACT LED flashing once every two seconds. The ACT LED of the redundant card flashes at a lower rate. Switch Module 37 2 Verify that at least one interface card of any type is installed in the CoreBuilder chassis in any interface card slots 3-6. Data is transferred between switch modules via a communications chip on an interface card. 3 Verify that the Ethernet management ports in both switches are connected to the NMS station. They can either be connected through a hub to the NMS station or through an Ethernet interface card in the same chassis, such as the CoreBuilder 7400 High Density Ethernet/ATM interface card, to the NMS station. During the procedure you will need to verify connectivity between the NMS station and the switch by pinging the switch module from the NMS station. Connectivity between the switch module and its attached devices is established by a coldStart trap transmitted by the switch module when it boots. The coldStart trap causes a device to learn the MAC address of the switch module. However, there are certain devices, for example, a Solaris station, which will not learn a new MAC address for an IP when one already exists. If you are using one of these devices as an NMS station, and you are unable to ping the switch module, try erasing the switch module’s MAC address from the device’s ARP table and ping again. 4 Verify that the RS-232 terminal line is connected to the console port on the main switch module. Procedure Execution 1 Reset the configuration of both switch modules by executing the CFGFRMAT.BAT file supplied with your software. To execute the CFGFRMAT.BAT file proceed as follows: a Perform the LMA command (1) SYS / (3) LOA / (3) LCL / 1 to put the system in Load Mode: Load. b Reboot the switch using the LMA menu command: (1) SYS / (7) RBO. The switch will reboot in debug mode. c Transfer the RS-232 cable to the service port of the main switch module. d From a DOS window on the LMA terminal execute > cfgfrmat com speed where “com” is the communications port you are using and “speed” is 115200 for a CoreBuilder 7000HD switch module and 57600 for a CoreBuilder 7000 switch module. 38 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES e Transfer the RS-232 cable to the service port of the redundant switch module. f Repeat step d) g Transfer the RS-232 cable to the console port of the main switch module. Hardware Redundancy Setup 2 Set up the main switch module using the Integrated Fast Setup (see “Integrated Fast Setup” on page 56). Do not reboot the switch from the Integrated Fast Setup procedure (answer “no” to the prompt). The main menu appears. 3 Wait for one minute to allow the configuration data to transfer from the main switch module to the redundant switch module. 4 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. This causes the configuration data to be recorded in flash memory and also causes the redundant switch module to become the main switch module. 5 After the switch reboots, answer “no” to the prompt: “Do you wish to erase the setup parameters”. 6 Run the Integrated Fast Setup procedure as in step 2) to verify that the setup parameters have been transferred correctly to the second switch (the Integrated Fast Setup procedure now displays the setup parameters resident in the second switch module). Press Enter repeatedly to verify these parameters; do not enter new values. 7 Verify that the ELAN names in the LECS database are identical in both switch modules. Use menu item (2) LEM/(1) LCS/(5) LNT to check that the LECS database of the second switch includes the ELAN name of the first switch. For example, Elan6666_0 - Elan6666_15 NMS-Based LANE Redundancy Setup 8 Verify connectivity between the switch module and the NMS station by pinging the switch module from the NMS station. 9 Load the Transcend application and open the Wizard Tool from the ATMvLAN tool bar 10 Open the Backbone and Services Window. 11 Configure the LECS order as desired and press the Apply button. 12 Configure the LECS database. Add all the primary and redundant ELAN names desired to the LECS database and press Apply. Make a list of the Switch Module 39 ELAN names you have selected. You will need them for setting up the other switch module. 13 When finished, close the Backbone and Services window. 14 Wait one minute to allow the LECS order database to transfer to the other switch module. The LECS ELAN database does not transfer automatically. 15 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. The purpose of this step is to make the first switch module active in order to set up the LANE services there. 16 After the first switch boots, check its connectivity with the NMS station as in step 8). 17 Perform steps 10) and 12) using the same list of ELANs. 18 Wait one minute. Verifying LANE Redundancy Setup 19 Use the MIB browser under the Transcend tools menu and browse through the MIB to verify that all the information regarding the LECS order list has been transferred correctly. Look in the following MIB location: ■ private ■ enterprises ■ atmForum ■ atmForumNetworkManagement ■ atmLanEmulation ■ elanMIB ■ elanLecsGroup ■ elanLecsConfGrou. ■ lecsConfTablelecsConfEntry ■ lecsAtmAddrSpec Press start query. The LECS order list is displayed on the bottom window. 20 Close the Backbone and Services Select window. 21 Open the Backbone and Services Select window again and use it to check that the LECS database is correct. 40 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES This item could be done through the LMA but it is preferred to do so through the NMS since the LMA will not show any redundant LES that exists. 22 Reboot the switch using the LMA menu sequence: (1) SYS / (7) RBO. The purpose of this step is to make the second card active in order to check the LANE services there. 23 After the second switch module boots, verify connectivity with the NMS station as in step 8). 24 Perform step 19) and 20) to verify LECS order. 25 Open the Backbone and Services Select window again and use it to check the LECS database is correct. The hardware and LANE redundancy procedure is finished. 4-Port Interface Module 4-Port Interface Module ATM Interface Daughter Cards 41 This section contains the following topics: ■ ATM Interface Daughter Cards ■ Installing the ATM Interface Daughter Cards ■ Installing a 4-Port Interface Module ■ Replacing a 4-Port Interface Module Each of the four ATM interface receptacles of the 4-Port ATM Interface module can be configured to support the following types of ATM daughter cards: ■ OC-3 multi-mode (MM) fiber link, single-mode (SM) fiber link ■ DS-3 coaxial cable ■ E-3 ATM 34.368 Mbits/sec WAN interface Figure 5 shows the OC-3 daughter card. Figure 5 OC-3 Daughter Card Figure 6 shows the DS-3 daughter card. 42 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES Figure 6 DS-3 Daughter Card Figure 7 shows the E-3 daughter card. Figure 7 E-3 Daughter Card 4-Port Interface Module Installing the ATM Interface Daughter Cards 43 The 4-port ATM interface module can hold up to four ATM interface daughter cards. The installation procedure of the 4-port ATM interface module comprises two stages. First, you install the ATM interface daughter cards in the 4-port ATM interface module. Then, you install the 4-port ATM interface module into the CoreBuilder 7000 family ATM switch chassis. To install the ATM interface daughter cards perform the following procedure: 1 Select the individual daughter cards that are to occupy the interface card’s four openings. 2 Align each module with the front panel aperture as shown in Figure 8 and press down to engage the strip connectors on the underside of the module. Three screws anchor each module to its seat on the interface card. Interface openings reserved for future use should be covered with blank panels. Used interfaces should use the coax or optical panels as covers. Figure 8 4-Port ATM Interface Module Installing a 4-Port Interface Module When the ports of the interface module have been fitted with the appropriate daughter card, you install the 4-port interface module into the CoreBuilder 7000 family ATM switch chassis. To install the 4-port interface module: 1 Orient the interface module so its labelling is upright and be certain that the inject handles are in the outward position. 2 Insert the card into the chassis by placing it between the guides of the selected slot and sliding the card until it stops. 3 Be certain that the card sits in the guide slots on either side. Be sure that the loose screws do not interfere with card insertion. 44 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES 4 Grab both inject handles and push them inward. This locks the card into the chassis. You may have to apply considerable pressure to the handles. An audible “click” indicates that the connectors have engaged. 5 Tighten the card’s securing screws. You are now ready to connect cables to the appropriate ports of the module. Replacing a 4-Port Interface Module To replace individual daughter cards, or to replace the entire interface module: 1 Disconnect the cables from the card's ports. Ensure that there is a record of where the cables are attached so that you can correctly re-connect them to the new card. 2 Loosen the screws at the extreme right and left of the card, near the insert/eject handles. 3 Grasp the insert/eject handles of the card you want to replace and push them outward. This ejects the card. You may have to apply considerable force to the handles. You will hear a “click” to indicate that the connections have separated, and the card will slide slightly forward out of the CoreBuilder chassis. 4 If you are replacing the entire interface card, remove the new card from its anti-static bag. Place the old card in the anti-static bag and set it aside in a safe place. Fan Tray To replace the fan tray: 1 Loosen the screws at the top and bottom of the fan tray. 2 Pull the fan tray out of the chassis. 3 Remove the new fan tray from its antistatic bag. Place the old fan tray in the antistatic bag and set it aside in a safe place. 4 Orient the fan tray so its labelling is upright. 5 Insert the new fan tray into the chassis by placing it between the guides of the slot and sliding it until it stops. 6 Tighten the fan tray’s securing screws. Connecting to Network Devices This section describes how to connect the CoreBuilder 7000 family ATM switch to different types of network devices. Connecting to Network Devices 45 Four types of connections are required: ■ Connecting to an ATM Optical Interface ■ Connecting the Control Terminal ■ Connecting to the Ethernet Port ■ Connecting to the Power Source To connect a CoreBuilder 7000 family ATM switch port to another CoreBuilder unit, to a LinkSwitch 2700 ATMLink adapter, or to any device with an ATM optical interface: Connecting to an ATM Optical Interface 1 Prepare an optical cable (Tx Rx). You may want to mark the ends of the cable so you can identify them. 2 Snap the cable into a CoreBuilder 7000 family ATM switch port in one of the interface modules. 3 Snap the other end of the cable into the selected optical interface of the other ATM device. Make sure that each wire connects to Rx on one end and Tx on the other. 4 Repeat steps 1-3 for all ATM port connections to the CoreBuilder. Perform steps 1-4 above when connecting a DS-3 coax cable set (Rx and Tx). Fiber Optic Power Budget of 3Com Products Table 8 shows the power budget of various 3Com products. Use this table when you calculate the length of fiber optic cable you need to connect to the CoreBuilder 7000 family ATM switch. See fiber optic cable manufacturers data for more information. .

To connect a terminal to the CoreBuilder 7000 family ATM switch control port: 1 Prepare an RS-232 shielded cable (9 pin-to-9 pin or 9 pin-to-25 pin, as dictated by the terminal you wish to use). 2 Configure the terminal: 19200 baud, 8 data bits, 1 stop bit, no parity, xon/xoff flow control. 3 Push the DCE side of the cable onto the Control port of the switch module and screw it into place. 4 Connect the other end of the cable to the terminal. In case you have installed a redundant switch unit, it is sufficient to connect the RS-232 line to either the active switch control port or to the redundant switch control port. Connecting to the Ethernet Port The Ethernet port is used for connecting directly to a Transcend Network Management System terminal for management purposes. Connecting to Network Devices 47 In case you have installed a redundant switch module, its Ethernet port must also be connected directly to the Transcend NMS terminal. Another way of connecting the Ethernet port to an out-of-band Ethernet network is to connect it to a CoreBuilder 7200 Ethernet/ATM Interface Card or a CB7400 High Density Ethernet/ATM Interface Card installed in the same chassis. Connecting to the Power Source This section describes how to connect the CoreBuilder 7000 family ATM switch to the power source. Selecting a Power Cord The following power cords and accessories are supplied with the unit: ■ 1 or 2 power cord(s) (2.5 meters each) ■ 1 strain relief bracket per power cord ■ 3 screws, M3 x 8 Phillips The power cord supplied with the unit can be used with loads of up to 5 Amps AC. If power cord(s) WERE NOT supplied with the unit, choose a cord based on the following information: ■ For units installed in the USA or Canada: Select a flexible, three-conductor power cord that is UL-listed and CSA-certified, with individual conductor wire size of #18 AWG, and with a maximum length of 4.5 meters. The power cord terminations should be NEMA Type 5-15P (three-prong earthing) at one end and IEC appliance inlet coupler at the other end. ■ The following types are acceptable: SV, SVE, SVO, SVT, SVTO, SVTOO, S, SE, SO, SOO, ST, STO, STOO, SJ, SJE, SJO, SJOO, SJT, SJTOO, SP-3, SPE-3, SPT-3, G, W. ■ For units installed in all other countries, select only a flexible, three-conductor power cord, approved by the cognizant safety organization of your country. The power cord must be of the type HAR (Harmonized), with an individual conductor wire size of 0.75 sq.mm. The power cord terminations should be a suitably-rated earthing-type plug at one end and an IEC appliance inlet coupler at the other end. Both of the power cord terminations must carry the certification label (mark) of the cognizant safety organization of your country. 48 CHAPTER 4: INSTALLING AND CONNECTING C OREBUILDER M ODULES Plugging in the Unit To plug in the unit: 1 Plug the power cord into the power source. 2 Plug the other end of the cord into the AC inlet located in the topmost section of the CoreBuilder 7000 family ATM switch front panel. Make sure the power cord is fully seated. A green power LED on the power supply should be lit. The unit is automatically powered up when the power cord is plugged in. 3 Be certain that the fans are working. If the fans are not working, unplug the unit immediately and see “Fans do not rotate” on page 94. 5 POWER-ON This chapter describes the system states of the CoreBuilder® 7000 family ATM switch including power-on and some basic diagnostic information to help you verify normal operation of your CoreBuilder system. This chapter describes the following topics: System States ■ System States ■ System Power-on ■ 4-Port Interface Module LEDs This section describes the different system states of the 8-Port Board and how they are indicated on the LED display. The system states are: System States and Switching Module LEDs ■ Power-on ■ Normal operation ■ Hardware fault ■ Software fault ■ No power to unit LED indicators are located on the front panels of the CoreBuilder 7000, its power supply, switching modules, and interface modules. These LEDs indicate the current system state of the CoreBuilder unit and its components. Front panel LEDs can be extremely useful in determining the cause of specific problems. The system state in which the CoreBuilder 7000 unit is currently operating is displayed by the switching module system status LEDs. Referring to Figure 9, these are the three LEDs: PWR, FAIL, and ACT(ive) 50 CHAPTER 5: POWER-ON on the left side of the LED panel. Table 9 shows the correlation between the current system state and SYS LEDs display. For example, during normal operation the PWR LED is on, the FAIL LED is off and the ACT LED is flashing. The LEDs on the right side of the panel indicate the status of the Ethernet port, the Service port and the Control port. PWR 10BASE-T Status FAIL Service Status ACT Control Status Figure 9 Switching Module LEDs Table 9 CoreBuilder System States System State Power (green) Fail (red) Activity (yellow) 10BASE-T Status (green) Service Port Status (green) Control Terminal Status (green) Power-on On Off On On Flashing Flashing Normal operation On Off Flashing On On On Hardware fault On On Off Off Off Off Software fault On Off Not flashing Undetermined Undetermined Undetermined No power to unit Off Off Off Off Off Off The following table also provides information about the LED display of system states but is organized by system status LED.

Software This section describes the stages of system power-on of the CoreBuilder 7000 family ATM switch. Apply electrical power to the system by inserting the power cord in the power supply unit. The power supply indicator lights and the CoreBuilder 7000 family ATM switch automatically runs diagnostic software. This software verifies that every component in the system is fully functional before the system becomes active on the network. Diagnostics should take sixty seconds or less. If any component fails power-on diagnostics, the system either fails to power on or it keeps faulty modules off-line. Once the system comes up, you can check to see which modules, if any, have failed diagnostics by checking the LED panels; in-depth information is available by viewing the system configuration screens on the administration console. Indicators 4-Port Interface Module LEDs All interface and switching unit indicators light at the start of the power-on diagnostic sequence, then go out briefly. General activity LEDs light up as the system checks the switching and interface modules. Finally, individual port indicators go on as the system discovers active connections residing on the interface modules. The 10BaseT indicator on the interface module is on during normal function, even if there is no active 10BaseT management link. Figure 10 shows the 4-port interface module LEDs. Table 11 and Table 12 list the permanent 4-port interface module panel LEDs. 52 CHAPTER 5: POWER-ON Figure 10 Interface Module LEDs Table 11 Description of Interface Module LEDs LED Color Description Source PWR (Power) Green DC power input active.

Using the terminal connected to the control port, you log into the system and assign network addresses to the CoreBuilder 7000 family ATM switch. This procedure enables the management of the site to recognize and communicate with the CoreBuilder 7000 family ATM switch. You also specify ATM connections between addresses, using the ATM protocol you have selected. The topics covered in this chapter include: Logging in to the LMA ■ Logging in to the LMA ■ Integrated Fast Setup ■ Additional Switch Configuration ■ Viewing Network Statistics. ■ Storing and Retrieving Configuration Parameters ■ Upgrading from E-IISP to PNNI When you boot the CoreBuilder 7000 family ATM switch the following login screen appears: ------------------------------CoreBuilder 7000 - ATM Backbone Switch ------------------------------Access level (read, write, admin):admin Password: 56 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH To log in to the LMA: 1 Enter your access level (default is admin) 2 Enter your password After a successful login the LMA Main Menu is displayed as shown in Figure 12.

With this procedure you can configure both the CoreBuilder 7000 family ATM switch card and all CoreBuilder 7X00 interface cards installed in it in one session. Integrated Fast Setup 57 In certain cases you will need to use the Fast Setup procedure of individual CoreBuilder 7X00 interface cards, in addition to the Integrated Fast Setup procedure, to correctly configure your system. This section presents the Integrated Fast Setup of the CoreBuilder 7000 family ATM switch card. It also explains when to use the Integrated Fast Setup of the CoreBuilder 7000 family ATM switch card and when to use the Fast Setup of an individual Corebuilder 7X00 interface card. For detailed information about how to use the Fast Setup of an individual Corebuilder 7X00 interface card, see the User Guide of the specific interface card. Chassis-oriented Setup The Integrated Fast Setup procedure is based on the concept that the CoreBuilder 7000 family ATM switch chassis together with its installed interface cards is viewed as an integrated unit. The advantage of this point of view is its simplicity: it is not necessary to remember in which slot each interface card is installed or even which type of interface card is installed. Attention is focussed on configuring the ports of the chassis. The procedure automatically determines the ports that are available in the chassis and presents them by type (Ethernet, Fast Ethernet, ATM) for configuration. The port location is displayed by the notation . For example <3.1> refers to slot #3, port #1. Chassis-wide VLANs With the Integrated Fast Setup, Virtual LANs (VLANs) can be created across the entire chassis. VLANs are set up in two stages. First, in the LE Client section, a number of potential VLANs are created according to the requirement of the network. Next, in the Virtual Network Configuration section, the potential VLANs become actual VLANs by having ports assigned to them. You need to define an administration “admin” VLAN to maintain SNMP connectivity to each device in the network. Using the Integrated Fast Setup you define one admin VLAN for the chassis; there is no need to define separate admin VLANs for each interface card. Note that from software version 3.5 on, the “admin” VLAN can now be called by any other name providing the same name is used consistently in the CB7000 and in all installed CB7X00 interface cards. When using the Integrated Fast Setup, the name for the admin VLAN which is specified for the switch module will be automatically chosen for the other modules 58 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH housed in the same CoreBuilder 7000 family ATM switch chassis, overriding any existing admin VLAN names. Setup Modes The Integrated Fast Setup provides two setup modes: the “Full” setup mode and the “Switch” setup mode. Full Setup Mode The Full setup mode configures both the CoreBuilder 7000 family ATM switch and the installed interface cards. It sets the required parameter values in all the installed interface cards. The Full setup mode presents only the most critical parameters; default values are assumed for the remaining parameters. This method is recommended for most users, especially for initial setup. Only those systems that require specific parameter settings in one or more of the installed interface cards will require the Switch setup mode described in the next section. Switch Setup Mode The Switch setup mode focuses only on the CoreBuilder 7000 family ATM switch and its ATM ports. The Switch setup mode allows you to retain special settings in the interface cards. In this mode, the installed interface card configurations cannot be changed. If you want to alter the settings in an interface card, use the Fast Setup of that interface card after you are finished using the Switch setup procedure. Setup Mode Selection If one of the following conditions is detected, the operator is prompted to choose between the Switch and Full setup modes: ■ A Subnet Mask, Default Gateway or NMS Address different from that of the CoreBuilder 7000 family ATM switch ■ A VLAN whose ATM connection is set to “No” ■ The name of the ELAN to which the default admin port (Port #1 in each slot) is attached is not the same in all interface cards. If none of these situations is detected, Full setup mode is automatically selected. Integrated Fast Setup 59 If Full setup is selected, the parameters in the interface cards revert to their default values. Setting Special Parameters If one or more individual interface cards requires one of the special situations referred to in the previous section or needs to remain unaltered, you need to do one of the following: Setup Procedure Sections ■ Use the Switch setup mode of the Integrated Fast Setup to set up the CoreBuilder 7000 family ATM switch only and then use the Fast Setup of each installed interface card separately. ■ Use the Full setup mode of the Integrated Fast Setup to configure the CoreBuilder 7000 family ATM switch and all installed interface cards and then use the Fast Setup for the particular interface card in order to restore its special parameter values. The Integrated Fast Setup procedure contains the following sections: Table 14 Setup Procedure Sections Setup Section Description 1 Routing Mode Set the Routing Protocol to be used 2 Network Prefix Set Network Prefix for CoreBuilder 7000 3 PNNI Parameter Set the PNNI node level (for the PNNI protocol — Version 4.5 extended only) 4 LE Parameters Set LE Parameters for CoreBuilder 7000 (LECS and LES states) 5 LECS Address Set resident active LECS address for CoreBuilder 7000 6 FastBUS Configuration Configure the FastBUS card if installed. 7 Interface Type Set the interface type port parameters for CoreBuilder 7000 8 LE Client Configuration Define potential VLANs by assigning names to ELANs. Exit this section by pressing Enter only. 9 Virtual Network Configuration Assign chassis ports to potential VLANs. 10 Admin VN Management Configuration Set up admin VLAN in all modules including setting IP address 11 Confirmation Confirm setup 60 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH Entering Data The Integrated Fast Setup procedure runs sequentially through the relevant data for all of the sections, displaying a prompt for each data item and a default value. If you want to change the default, enter the desired value in place of the default. If you want to accept the default, press Enter. Default Parameter Values The default parameter value displayed at the prompt is the value stored in flash memory. In case there is no value in flash memory, the factory default value is displayed.

There are four interface types: UNI, E-IISP, IISP and PNNI. The UNI type is normally used when an edge device is connecting to a switch. The E-IISP type is normally used when connecting to another CoreBuilder 7000 or 9000 switch. The IISP type is used to connect to a device which does not recognize the E-IISP protocol used by the CoreBuilder 7000 family ATM switch such as switches of other vendors. The PNNI type is normally used to connect switches to other similar or different types of switches when you want each switch to have a global view of the entire network. PNNI is available in version 4.5 extended only. To enter the interface type configuration: 1 At the NNI type of port prompt, enter the NNI type for the port you just specified. Enter “U” for UNI, enter “E” for E-IISP, enter “I” for IISP, or “P” for PNNI. 2 Repeat step 1 until you have specified the interface type for all of the ports that are in the Corebuilder 7000 family ATM switch chassis. Interface type =------------NNI type of port NNI type of port NNI type of port NNI type of port <3.1> (U , E , I , P ): U <3.2> (U , E , I , P ): P <3.3> (U , E , I , P ): E <3.4> (U , E , I , P ): I 66 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH 3 The LMA automatically prompts you to enter ATM addresses for the ports that you have specified as IISP. These are ATM addresses of network devices that you want the IISP port to recognize for routing purposes. They are placed in the routing table of the port. You need to enter these addresses manually because the IISP protocol does not automatically recognize them. You can enter more than one address; press Enter to end the sequence of addresses. *** The following are addresses of ports you have defined as IISP. You may enter more than one address per port. When you have finished press : ATM address for port <5.2> (19 bytes-When less: end with '.*'): 47.00.00.00.00.00.3e.00.00.b0.00.c0.da.69.00.c0.da.11.22 ATM address was set for port <5.2> ATM address for port <5.2> (19 bytes-When less: end with '.*'): 47.00.00.00.00.00.3e.00.00.b0.00.00.00.00.c0.da.11.22.00 ATM address was set for port <5.2> ATM address for port <5.2> (19 bytes-When less: end with '.*'): 4 The LMA automatically prompts you for the NNI type of the ports that you have specified as IISP. Specify the NNI type as User or Network. *** The following is a profile of ports you have defined as Gateway: Profile of port <5.2> (U , N ): N 5 Repeat until you have specified all the IISP ports. LE Client Configuration Section This section prompts you for the LAN Emulation Client configuration. You give names to the ELANs that you want to be active in the network. In the Virtual Network Configuration section, you will assign Ethernet ports to the ELANs you have named in this section to create VLANs. Until then, the ELANs are considered potential ELANs. You can enter the names of resident ELANs of the switch you are setting up and you can enter names of ELANs from other devices in the network. You can define any number of potential ELANs. To end the sequence, press Enter. The names of the ELANs resident on a particular switch all have the form elanXXXX_n where “XXXX” is a number unique to the switch and “n” is Integrated Fast Setup 67 the sequential number of the ELAN. This is the form you need to use for ELANs that you enter in this section (except for the admin ELAN). You are first prompted for the name of the admin VLAN. The default name displayed is the name of the admin VLAN of the CoreBuilder 7X00 which is installed in the highest occupied slot in the CoreBuilder chassis. You can change it if you wish. The name for the admin VLAN which is specified in this section will be automatically chosen for the other modules housed in the same CoreBuilder 7000 family ATM switch chassis, overriding any existing admin VLAN names. For this section and the Virtual Network Configuration section to operate correctly, at least one CoreBuilder 7X00 interface card must be installed in the CoreBuilder 7000 family ATM switch chassis. The following shows a typical LE Client Configuration. Make a list of the ELAN names and the numbers to which they are assigned in this section for later use in the Virtual Network Configuration section. 68 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH LE Client Configuration -=--------------------*** Hit Enter after VN #2 for end of potential ELAN names list.

In this section, you assign Ethernet ports to the ELANs you entered in the LE Client Configuration section. The Ethernet ports of the CoreBuilder 7X00 interface cards installed in the CoreBuilder 7000 family ATM switch chassis are displayed sequentially. For each port, you enter the number of the ELAN to which you want that port to belong. To end the sequence, press Enter. At the end of the section, a list of the ELANs that were entered in the LE Client Configuration section but did not have ports assigned to them in this section is displayed.

Additional Switch Configuration The Integrated Fast Setup configures a minimum set of network parameters - enough to get you started. If you need to make changes or to perform additional configuration tasks, use individual items of the LMA menus. These are all described in the CoreBuilder 7000 Family ATM Switches Management Guide. Some additional configuration tasks might be: Additional Switch Configuration 73 Configuring SVCs CoreBuilder 7000 family ATM switches use standard UNI 3.0, 3.1 or 4.0 switched virtual channel (SVC). SVC mode can be used when CoreBuilder is in a backbone or workgroup topology, with PVC used whenever necessary. ILMI enables automatic address registration for SVC. Addresses can be registered manually via the LMA menus. Changing the UNI Version The CoreBuilder will run UNI 4.0 SVC by default. You can work in UNI 3.0 or UNI 3.1 by choosing this option in the signalling setup menu. Configuring Network Prefix and ATM Addresses ATM addresses are essential for establishing a connection using SVC. Most devices that support SVC, also support automatic address registration through the ILMI protocol. A network prefix is essential for address registration to be executed. Refer to CoreBuilder 7000 Family ATM Switches Management Guide for proper network prefix setting. For connectivity with devices that do not support ILMI, ATM addresses can be set manually using the Add ATM address function under ATM address setup in the Administration Console menus. Configuring a PVC Permanent Virtual Channels (PVC) can be used to connect to devices that do not support switched virtual channels (SVC) standard protocols. In the CoreBuilder 7000 family ATM switch you can create point-to-point (P2P) and point-to-multipoint (P2M) connections. Use the Setup and Configuration Connections menu, to create a PVC call, PTP or PTM. You can also create an out VC in a PTM call, release a PVC call, release an out VC from call, save PVC connections in flash memory and reset saved connections. Up to 2000 PVCs can be configured. Configuring Clock Synchronization External clock synchronization allows a clock to be received on one of the bottom of 4 OC-3c ports of an 8-port interface card from an external source, and to be distributed to all bottom OC-3c ports on the same card and other 8-port interface cards in the same chassis. It is used in voice and data applications so that the same port is used at the same time. You can configure one port to be the master port which will distribute its 74 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH information to the other ports (slave ports). For more information, see “Set and Save Clock Synchronization Mode” on page 120 in the Management Guide Viewing Network Statistics At any time after configuring the CoreBuilder 7000 family ATM switch, you can view the available statistics to see how the network is functioning. For example, you may want to display the general statistics for an overview of the network, or the signalling statistics for protocol information on specific ports. Table 17 lists the types of statistics available. To view a specific statistic, enter the menu path shown in the table.

Storing and Retrieving Configuration Parameters Configuration Upload/Download This section discusses the configuration upload/download facility and includes the following topics: ■ Configuration Upload/Download ■ Organizing Configuration Files ■ Activating the Downloaded Configuration ■ Uploading the Configuration of a Card ■ Downloading the Configuration of a Card ■ Loading Software and Configuration Data by Utilities You can store (upload) the configuration of an installed card from its flash memory to an external disk and restore it (download) to the flash memory of the original card — or to the flash memory of a different card of the same type — at a later time. You can initiate this operation only through the LMA and not via a SNMP management application like Transcend. This feature lets you: ■ Back up your switch configuration in case of switch failure ■ Transfer the configuration from one switch to another ■ Maintain various standard configuration templates which can be loaded according to requirement The configuration upload works for individual cards installed in the CoreBuilder 7000: either the active switch card or a CoreBuilder 7X00 Interface Card. You select the card whose configuration you want to download or upload from a list of installed cards. When the switch operates in single-IP mode, you can use this facility to upload the configuration of any of the installed cards through the LMA of the switch card. When the switch is operating in multiple-IP mode, you can use this facility to upload the configuration of the switch card only. 76 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH You cannot upload or download configuration parameters to a switch card while it is installed as a redundant switch card. You need to remove the card from the chassis, install it in a different switch chassis as the active switch card and then perform the upload/download operation, as described below. Afterwards, return the card to its slot in the original chassis. Uploading Selected Data Types The CoreBuilder 7000 allows you to upload selected types of configuration data. The types of configuration data you can upload depends on the card you selected. For the switch card, the types of configuration data you can upload are as follows: ■ All Configuration Data ■ Platform Parameters ■ ATM Addresses ■ PNNI Configuration ■ LANE Security ■ PVC Connections ■ LECS Topology ■ LECS Order List For a CoreBuilder 7X00 card, the data types are as follows: Organizing Configuration Files ■ Platform Parameters ■ Static The uploaded configuration files can be named using a naming convention of your choice. Normally, you will want to include information about the data type, the card type and a date or other identifier in the file name. For example, you might use file names like cfg_7000_12jun98 and static_7600_1. When you download configuration data from the files on the disk to the card, you designate the card by its slot number. The slot can contain the original card from which the data was uploaded, or it can contain another card of the same type. If you try to download configuration data which was uploaded from one type of card type to another type of card, an appropriate error message is issued. Storing and Retrieving Configuration Parameters Activating the Downloaded Configuration 77 When the configuration files are downloaded into flash memory, they overwrite the previous information. The new parameters are not activated immediately, but rather after the next reboot when they are read from the flash memory. The CoreBuilder 7000 assumes that the user wants to reboot the switch as soon as possible to activate the new configuration parameters. Therefore, subsequent to a configuration download, all LMA and SNMP set operations are blocked until the next reboot – except for the configuration upload/download and reboot operations. It is recommended, therefore, to perform a configuration download only when you are ready to reboot and activate the new parameters. Cards should not be “hot swapped” after a configuration download until after the next reboot. Uploading the Configuration of a Card To store (upload) the configuration of a card installed in the CoreBuilder chassis from flash memory to disk, first make sure that the switch is connected to the TFTP server and that it is in single-IP mode and then perform the following steps: 1 Perform the LMA menu command: (1) SYS\ (3) LOA \(6) TCU 2 The LMA automatically presents you with a list of the installed cards whose configuration you can upload to disk, for example: Module Types: 1 2 3 4 5 Select Module: 1 Select the appropriate card from the list—for example, if you want to upload the configuration of the active switch card, select 1 from the menu. 3 The types of configuration data you can upload are displayed as follows: File Types: 1 2 3 4 5 6 78 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH 7 8 9 Select File type: Enter the number of the type of configuration parameters you want to upload. For example, if you want to upload all configuration parameters, select File type 1. 4 Enter the IP address of the TFTP server: Server IP address: 100.0.0.111 5 Enter the name of the file to receive the data on disk: Name of file to be uploaded: 7000_cfg Enter a file name without an extension. For the “All” option, the system adds sequential extensions. 6 Confirm the upload. Start upload to 100.0.0.111, file name 7000_cfg, (Y/N)? y The following messages are displayed for each data type: Loading, file name switch/cfg/24_7_cfg.1, file type Box Profile Load process of file type Box Profile completed successfully 7 Verify the success status of the upload by the LMA menu item: (1) SYS:\ (3) LOA: \(1) STS The upload status is displayed as follows: Load process completed successfully. The status will be “success” only if all the files were successfully loaded. In case of failure to load a file, the “load all” process will be stopped without continuing to the next file, a failure indication is displayed, and the display status option displays the error message: General Error occurred while loading Loading a Single Configuration Data Type If you want to upload a single data type instead of the entire configuration, proceed as follows from step 3: 3 Select File type: 2 4 Server IP address: 100.0.0.111 5 Name of file to be uploaded: switch/cfg/box_prof.cfg Storing and Retrieving Configuration Parameters 79 For loading a single item you can enter a full file name. 6 Start upload to 100.0.0.111, file name switch/cfg/box_prof.cfg, Box Profile (Y/N)? y Load process started... Loading the “Other” Data Type The “Other” item allows you to specify a file type by code number. This option is relevant to configuration data items in the CoreBuilder 7X00 cards and are specified in the Release Notes for those products; the configuration data item and its number (0–9999) are specified there. If you want to upload the “Other” data type, proceed as follows from step 3: 3 Select File type: 9 4 Insert file type (0-9999): 1001 5 Server IP address: 100.0.0.111 6 Name of file to be uploaded: switch/cfg/unknown.cfg 7 Start upload to 100.0.0.111, file name switch/cfg/unknown.cfg, 1001 (Y/N)? y Load process started... Downloading the Configuration of a Card To retrieve (download) the configuration of a card installed in the CoreBuilder chassis from disk to flash memory, first make sure that the switch is connected to the TFTP server and then perform the following steps: 1 Perform the LMA menu command: (1) SYS\ (3) LOA \(7) TCD 2 The LMA automatically presents you with a list of the installed cards whose configuration you can download from disk, for example: Module Types: 1 2 3 4 5 Select Module: 1 80 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH Select the appropriate card from the list—for example, if you want to download the configuration of the active switch card, select 1 from the menu. Make sure you select a type of card that matches the configuration data on the files you want to download. In this case, the data on the files must have been uploaded from a switch card. If you choose the wrong type, the data will not be downloaded and you will get an error message. 3 The types of configuration data you can download are displayed as follows. File Types: 1 2 3 4 5 6 7 8 9 Select File type: Enter the number of the type of configuration parameters you want to download. For example, if you want to download all configuration parameters, select File type 1. 4 Enter the IP address of the TFTP server: Server IP address: 100.0.0.111 5 Enter the name of the file to receive the data on disk: Name of file to be downloaded: 7000_cfg Enter a file name without an extension. For the “All” option, the system adds sequential extensions. After you confirm the download, all LMA and SNMP set operations are disabled until the download is finished and you reboot the system. The following warning is displayed: Warning: This action will disable set operations on the target Device. 6 Confirm the download. Start download to 100.0.0.111, file name 7000_cfg, (Y/N)? y The following messages are displayed for each data type: Storing and Retrieving Configuration Parameters 81 Loading, file name switch/cfg/24_7_cfg.1, file type Box Profile Load process of file type Box Profile completed successfully 7 Verify the success status of the download by the LMA menu item: (1) SYS:\ (3) LOA: \(1) STS The download status is displayed as follows: Load process completed successfully.

In case of failure to load a file, the “load all” process will be stopped without continuing to the next file, a failure indication is displayed, and the display status option will display the error message: General Error occurred while loading Loading Software and Configuration Data by Utilities The following commands allow you to use RS-232 batch-file utilities to download and upload the executable software and the system configuration parameters for the CoreBuilder 7000 family ATM switch to an external disk via the RS-232 service port. This ability allows you to easily restore the configuration to a switch which has failed or to configure a new switch with a standard configuration stored on disk. The appropriate batch file is run via the RS-232 service port. Table 18 shows the utilities and the batch file names.

Upgrading from E-IISP to PNNI For full upgrade instructions, see Chapter 6 in the CoreBuilder 7000 Family ATM Switches Management Guide.The CoreBuilder 7000 has a special gateway function which allows E-IISP to PNNI connectivity and vice versa. PNNI is available in version 4.5 extended only. PNNI in E-IISP Connecting PNNI to E-IISP is done in two ways: ■ Using the 3.1 interface ■ Using the PNNI to IISP/E-IISP gateway Connecting PNNI to E-IISP and IISP networks requires addressing to match (use the same E.164 addressing scheme) in order to guarantee uniqueness. This is necessary because PNNI works on the best match routing scheme. The PNNI gateway function will advertise IISP and/or E-IISP addresses as either native or as foreign reachability addresses. 84 CHAPTER 6: CONFIGURING THE COREBUILDER 7000 FAMILY ATM SWITCH Migrating from E-IISP to PNNI In order to migrate successfully to PNNI, the network manager must review the network address scheme that will be used. There are two possible approaches to implementing address change: ■ Deriving a PNNI peer group ID and peer group level based on the E-IISP addressing scheme. See Chapter 3 in the Operations Guide for information on E-IISP addressing. ■ Changing the E-IISP network prefixes to match the PNNI addressing scheme. The gateway between E-IISP and PNNI must be between the E-IISP highest level and the PNNI gateway node. 7 REDUNDANCY IN THE COREBUILDER 7000 FAMILY ATM SWITCH This chapter describes power supply redundancy in the CoreBuilder® 7000 family ATM switch. The operation of each redundant device is described. For information on installing redundant devices, see Chapter 4. For further information on switch redundancy, see the CoreBuilder 7000 Family ATM Switch Operations Guide. This chapter includes the following topic: ■ Redundant Power Supply Types of Power Supplies Redundant Power Supply This section discusses the following topics: ■ Types of power supplies available ■ Power requirements of the CoreBuilder 7000 family switching and interface cards ■ Using redundant switching cards and redundant power supplies. The CoreBuilder 7000 family supports three kinds of power supplies: an AC unit rated at 90A, and two DC units rated at 90A and 40A. You can use each one of them in any CoreBuilder 7000 family ATM switch. The power supply supports two output channels: one 5V DC channel which supplies the CoreBuilder switch and the interfaces cards, and one 12V DC channel which supplies the fans. 86 CHAPTER 7: REDUNDANCY IN THE COREBUILDER 7000 FAMILY ATM SWITCH The CoreBuilder 7000 family power supplies are shown in Table 19. Table 19 CoreBuilder 7000 Family Power Supplies Power Supply Operation Power Supply Current 3Com Number CoreBuilder 7000/7000HD AC Power Supply 90A 3C37010A CoreBuilder 7000/7000HD DC Power Supply 90A 3C37027 CoreBuilder 7000/7000HD DC Power Supply 40A 3C37026 Load Sharing The power supplies can operate in load-sharing mode; two 90A power supplies can produce up to 180A. Providing that the power consumption of the unit does not exceed 90 A, load-sharing allows one power supply to serve as a backup. Overloading When the installed power supply is rated for less than the required power consumption of the CoreBuilder module, the CoreBuilder will not succeed in powering up. It will attempt to power up, hit the current overload rate and turn the power supply off, going through this cycle repeatedly until the load is reduced. Calculating the Power Consumption of CoreBuilder Switch The power consumption of an entire CoreBuilder 7000 family ATM switch unit is calculated by adding up the power consumption of the switching card(s) and interface cards installed in the chassis. Normally, the values for typical power consumption can be used in the calculation. Table 20 shows the typical power consumption values for the CoreBuilder 7000 family ATM switching cards and interface cards.

The first column describes the particular combination of cards installed and covers the most common applications. The second column shows the number of power supplies required if a redundant switch is not installed; the third column shows the number of power supplies required if a redundant switch is installed.

In order to determine whether a redundant switch card and/or an redundant power supply can be used in a CoreBuilder switch, the total power consumption of all installed cards must be examined. According to the total power consumption, there are three possibilities, as the following examples illustrate: Installation I: The total power consumption of a single switching card (that is, no redundant card installed) and all interface cards exceeds 90A. In this case, a Dual 90A supply is required so that the second power supply cannot be redundant. A redundant switch card can be installed. This “heavy load” installation is illustrated by the first example installation in Table 21. Installation II: The total power consumption of two switching cards (i.e., redundant card installed) and all interface cards exceeds 90A but without the second switching card the consumption is less than 90A. In this case, either a redundant switch card or a redundant power supply can be installed, but not both. This “medium load” installation is illustrated by the second example installation in Table 21. Installation III: The total power consumption of two switching cards and all interface cards does not exceed 90A. In this case, both a redundant switch card and a redundant power supply can be installed. The light load installation is illustrated by the fourth example installation in Table 21. In all installations that do not include multiple CB7600 cards both redundant switch cards and redundant power supplies can be installed.

It also shows how to perform related diagnostic tasks, such as replacing fuses or cleaning fiber optic cables. If you experience problems that are not addressed in this chapter, contact 3Com Technical Support (see Appendix E). Solving Common Problems The following problems may arise while working with the CoreBuilder® 7000 family ATM switch. If your problem does not appear on this list, view relevant statistics and parameters using the Administration Console menus (refer to the CoreBuilder 7000 Family ATM Switches Management Guide). You can also contact 3Com Technical Support. Also, be sure to read through the release notes. Table 13 Recommended Action for Common Problems Problem Recommended Action Terminal does not show anything If the control terminal is physically connected to the CoreBuilder 7000 family ATM switch, but does not load the Administration Console Menus, verify that your terminal setup matches the specifications (see “Connecting the Control Terminal” on page 46). Also, make sure your cable is configured as DCE (see “Ethernet Cabling” on page 118). Port cables do not work If the cables attached to the CoreBuilder 7000 family ATM switch interface ports do not work, check that the connectors are firmly snapped in place. Also, make sure that each wire connects to Rx on one end and Tx on the other. ACT LED not blinking When the CoreBuilder 7000 family ATM switch is activated, the switch module and interface cards ACT LEDs should be blinking. If not, verify that the switch module and interface cards are properly inserted. Make sure that the control terminal is connected to the control port correctly, as an incorrect connection of this cable sometimes results in the inability of the system to function properly. 94 CHAPTER 8: TROUBLESHOOTING Table 13 Recommended Action for Common Problems (continued) Problem Recommended Action Interface Card fails If one of the interface cards fails, use the Initialize Interface (INI) option in the System (SYS) menu, Interface (IFC) option to reinitialize the interface. If this fails, you can try to restart the whole unit again. If neither of these actions correct the problem you should contact a 3Com service person. When handling modules, always use a wrist strap that is connected to a proper ground. This prevents the module from being damaged by electrostatic discharge. Fans do not rotate If the fans do not work when the unit is powered up, the fan tray may not be inserted properly. Unplug the power cord and reinsert the fan tray properly against the enclosure. Power Supply Troubleshooting This section discusses common problems related to the CoreBuilder 7000 family ATM switch power supply. Table 14 Problems Related to the Power Supply Problem CoreBuilder 7000 family ATM switch not receiving power Possible Cause ■ ■ ■ The CoreBuilder 7000 family ATM switch is not connected to/receiving external power. The power supply malfunctioned. A fuse is blown. Recommended Action 1 Check that the power cord is firmly plugged into both the system and the building’s power outlet. 2 Check that the power cable meets the requirements described in the Safety Rules section of Chapter 3. 3 Restart the system by replugging the power cord. 4 If the problem persists, consider replacing the power cable, replacing the power supply and checking the power supply fuse; the fuse resides within the power supply. You have to extract the power supply in order to check and replace a fuse. 5 If the system is still not operating, contact 3Com Technical Support or your service person. Circuit breaker has tripped ■ ■ External wiring problem Power supply failure 1 Unplug the power cord of the system. 2 Verify that the system is properly connected to AC power with the correct voltage. See Appendix A: CoreBuilder 7000 Family ATM Switch Specifications. 3 If the power connection is the problem, replace the cable. If the problem remains, contact 3Com Technical Support. Related Diagnostic Procedures Related Diagnostic Procedures 95 When troubleshooting problems occur, you may have to perform minor procedures to help correct the problem. These procedures are described below. For more complex operations on the CoreBuilder 7000 family ATM switch, contact 3Com Technical Support. Table 15 Diagnostic Procedures Procedure Action Checking fan operations In case of system overheating, check that the power supply fan and the fans in the fan tray are operating. To check for fan movement in the CoreBuilder 7000 family ATM switch’s fan tray, pull a few modules from the chassis to view the fans on the left side of the system. Cleaning dirty fiber optic cables* Fiber optic transceivers are sensitive optical devices that need to be handled carefully. If dirt collects on the fiber optic lens, you may notice that the LED for an ATM port link status does not light. You may also notice degraded performance of that port, indicated by an increase in the physical layer statistics count for that port. To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at all times when they are not in use. To clean a fiber optic lens, follow the procedure below: 1 Remove any accumulated dust or debris from the port or connector by blowing off all surfaces with a canned air duster. 2 Compressed gas is recommended, such as Chemtronics’ Ultrajet ® or the Triangle Tool Group’s Liqui-Too!™ Dust-A-Way. Do not use commercial compressed air or “house air” because of the risk of oil contamination. 3 Reconnect the cable to the port to see if the dusting corrected the problem. 4 If the LED still does not appear, or if it lights yellow, continue with steps 5 and 6. 5 Gently wipe the ports with a lint-free, non-abrasive, non-adhesive swab. Microswabs™ by Texwipe™ are recommended. 6 Gently wipe the connectors with a lint-free, non-abrasive wipe or pad. Texwipe™ pads are recommended. * See safety precautions in next section. Safety Precautions for Fiber Optics Connectors Avoid touching all surfaces after cleaning the connectors, and keep all unused ports covered. Vermeiden Sie das Berühren aller Oberflächen nach dem Säubern der Kontakte und verdecken Sie alle nicht benutzten Öffnungen. Ne toucher aucune surface après le nettoyage des connecteurs et garder les pièces inutilisées couvertes. 96 CHAPTER 8: TROUBLESHOOTING A ATM SWITCH FA/24 CELL SWITCHING MODULE SPECIFICATIONS ■ Height: 38.8 cm (15.3 in) ■ Width: 3.81 cm (1.5 in) ■ Depth: 32.7 cm (12.8 in) ■ Weight: 1.7 kg (3.74 lb) Operating Temperature ■ 0° to 40° C (32° to 104° F) Operating Humidity ■ 10 to 90% relative humidity, non-condensing Storage Temperature ■ -20° to 75° C (-4° to 167° F) Storage Humidity ■ 95% maximum relative humidity, non-condensing Thermal Rating ■ 505 watts maximum ■ 1724 BTU/hour maximum Physical Dimensions Environmental Requirements Safety Agency Certifications ■ Designed to Comply with ■ VDE 0871 part 2 class A, EN 55022 AC Protection ■ 20 amp circuit breaker ■ Meets FCC part 15, Subparagraph B, Class A limits.

This includes the following elements: ■ Performing all necessary planning, ordering, installing, and maintenance. ■ When required, contacting the appropriate facilities manager for assistance. ■ Ensuring that all building and electrical code requirements (national, state, and local) are met. Environmental and Safety Requirements This section includes environmental and safety requirements are applicable to the installation of the CoreBuilder 7000 family ATM switch. Protective Grounding For your safety and to ensure optimum performance of the system, verify that all protective grounding requirements have been met in accordance with the applicable national, state, and local electrical codes. You must also verify that you have properly grounded the distribution rack. This is normally done with a distribution rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground. Proper distribution rack grounding will ensure that voltages induced into wiring by lightning or other disturbances are directed to ground. Environmental Specifications For the system to operate properly, the following environmental conditions should exist: ■ Ambient air temperature: 0° to 40° C (32° to 104° F). ■ Operating humidity: 10 to 95% relative humidity (non-condensing). 106 APPENDIX C: SITE R EQUIREMENTS ■ Thermal Recommendations General Recommendations Power and Heat Specifications Wiring Closet Considerations Power requirements: 115-Volts AC power, 15-Amp service receptacles, type N5/15 or NEMA 5-15R (for U.S.) or 220 Volts AC for Europe. This sections contains recommendations for handling the heat generated by the CoreBuilder 7000 family ATM switch. It is essential that you provide a suitable environment for both performance and safety. The following are some general thermal recommendations for the wiring closet: ■ Ensure that the ventilation in the wiring closet is adequate to maintain a temperature below 40° C (104° F). ■ During non-business hours, make sure that the ventilation is not shut down while a CoreBuilder 7000 family ATM switch remains powered up; otherwise, the equipment may overheat. The following are power and heat specifications for the CoreBuilder 7000 family ATM switch: ■ Maximum power consumption: 250 Watts ■ Maximum heat generated: 1724 BTU per hour ■ Operating temperature: 0° to 40° C (32° to 104° F) The cabling system used at the facility should cover the majority of wiring closet concerns. You may want to consider the following recommendations. ■ Verify that the facility meets all requirements mentioned in the system cabling plan. ■ Ensure that the system is easily accessible for installation and service. ■ Use AC power, 15-Amp service receptacles, type N5/15 or NEMA 5-15R for 120Vac. ■ Select a vinyl floor covering for the wiring closet. (Concrete floors tend to accumulate dust, and carpets often cause static electricity.) ■ Ensure that the wiring closet floor is flat and level. If the floor is not level, ensure that the racks are bolted to the floor to prevent them from tipping over. Distribution Rack Requirements Distribution Rack Requirements 107 ■ Ensure that all wiring closets have doors with locks to prevent unauthorized access. ■ Provide adequate overhead lighting in the wiring closet for easy maintenance. ■ Ensure that each wiring closet has a suitable ground. All metal racks, enclosures, boxes, and raceways in the closet should be grounded. ■ Assign wiring closet identification numbers using architectural location codes or some type of floor grid matrix. ■ Ensure that all system environmental requirements are met (such as ambient temperature and humidity). This section describes the basic mechanical and space requirements for the distribution rack (refer to Figure 16). Figure 16 Distribution racks Mechanical Requirements Racks should comply with the standards and requirements mentioned in the cabling system plan and should conform to conventional standards. In the United States, use EIA Standard RS-310C: Racks, Panels, and Associated Equipment. In countries other than the United States, use IEC Standard 297: Dimensions of Panels and Racks. The following are distribution rack requirements: 108 APPENDIX C: SITE R EQUIREMENTS ■ Use an open style, 19-inch rack. The rack styles shown in Figure 16 facilitate easy maintenance and provide excellent ventilation. ■ The rack should use the universal mounting rail hole pattern identified in IEC Standard 297. ■ The rack should be made of steel. ■ The rack should support approximately 272 kilograms (600 pounds). ■ The rack should have adequate electrical grounding. A distribution rack grounding kit may be used. ■ The rack should be attached to the wiring closet floor with 9.5 millimeters (3/8 inch) lag screws or equivalent hardware. The floor under the rack should be level within 5 millimeters (3/16 inch). Use a floor leveling cement compound if necessary or bolt the racks to the floor. ■ Brace open racks if the channel thickness is less than 6.4 millimeters (1/4 inch). ■ Install equipment in the lower half of the equipment rack to avoid making the rack top too heavy. D CABLING REQUIREMENTS This appendix addresses many aspects of installing optical fiber cabling to support the CoreBuilder® 7000 family ATM switch environment. It also deals with modem cables and Ethernet and control cables for management. The following topics are covered: Installing New Cabling Cable Labeling and Record Keeping ■ Installing New Cabling ■ ATM Cabling ■ Ethernet Cabling If you are installing new cabling, follow these guidelines: ■ 3Com recommends that you use a cabling system plan, such as AT&T's Premises Distribution System (PDS) or the IBM Cabling System. ■ Determine how many CoreBuilder 7000 units are going to be supported by each wiring closet, and how many downlink connections from these CoreBuilder 7000 units are planned. ■ Locate wiring closets to enable connections to the different floors. ■ To simplify installation of the network and to aid in troubleshooting, install a telephone in each wiring closet for communication between wiring closets, work areas, and other locations. ■ Include all linear distances (vertical rises, etc.) in the cable plan so that all cables - from wiring closet to desk and to other wiring closets - are under their respective maximum lengths. A reliable cable labelling and record keeping system is essential when planning any network installation. A good cable labelling system provides enough information for you to locate the opposite end of any cable. Maintaining accurate records helps you to: ■ relocate devices easily 110 APPENDIX D: CABLING R EQUIREMENTS ■ make changes quickly ■ isolate faults in the distribution system Consult the cabling system plan to set up the cable labeling and record keeping system best suited to the environment. Also consider the following recommendations: ATM Cabling ■ Identify cables by securely attaching a label to the ends of all cables. ■ Draw a floor location grid matrix using the building floor plans. For easy reference, use this grid when assigning location numbers to cables. ■ Assign a unique block of sequential numbers to the group of cables that run between each pair of wiring closets. ■ Assign a unique identification number to each distribution rack. ■ Make all work areas and wiring closets easy to identify by labeling the front panel of the CoreBuilder 7000 and other hardware and by displaying the floor location grid and cabling plan in each wiring closet. ■ Keep accurate and up-to-date cable identification records, such as IBM's Cable Identification Label Sheet or Cable Schedule. Post records near each distribution rack. On the appropriate cable schedule, record the following cable drop information: the cable source, destination, jumper location, and any additional information. ■ Make sure that optical and coax cables are labeled Rx and Tx accordingly. When planning the installation, thoroughly inspect the present cabling to determine if it meets the specifications in the cabling system or standards used at the site. In addition to adhering to the local standards, all cable must conform to the American National Standard ATM Physical Layer Medium Dependent (PMD) standard, ISO.166-1990, American National Standards Institute, which defines the Physical Medium Dependent (PMD) layer of the ATM network. Currently, there are two approved PMD standards: Multi-mode Fiber (MMF-PMD), which is defined in ANSI standard X.3-166-1992, and Single Mode Fiber (SMF-PMD), which is defined in ANSI standard x.3-184-198x. ATM Cabling 111 3Com supports multi-mode fiber (MMF-PMD) 62.5/125 µm and Category one (1) single mode fiber (short reach) (SMF-PMD). When deciding whether to use multi-mode or single mode fiber, determine the maximum interstation distance (the distance from the CoreBuilder 7000 to any potential end station): Caring for Fiber Optic Transceivers ■ If the maximum interstation distance is less than or equal to 2 kilometers (1.25 miles), use multi-mode fiber (MMF-PMD). ■ If the maximum interstation distance is greater than 2 kilometers (1.25 miles) and less than or equal to 14.4 kilometers (8.6 miles), use single mode fiber (short reach) (SMF-PMD). Fiber optic transceivers are sensitive optical devices that need careful handling. The following information offers suggestions about caring for fiber optic cable. Dirt on the Fiber Optic Lens If dirt collects on the fiber optic lens, you may notice that the LED for an ATM port either does not light or lights yellow. You may also notice degraded performance of that port, as indicated by a decrease in the Link Error Rate (LER) estimate for that port. To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at all times when they are not in use. To clean a fiber optic lens when it becomes dirty, see “Cleaning dirty fiber optic cables” on page 95. Damaged Transceiver Due to Excessive Insertion Force The ATM specification for insertion force on the connector into an ATM SC receptacle is 3.5 lbs. However, it is possible to exert up to 30 lbs. of insertion force on the transceiver if you are too forceful while inserting the SC connector into the receptacle. This can cause failure of the transceiver's mechanical joints, permanently damaging the part and disabling the port. When inserting connectors into the ATM ports, gently insert the SC connector into the receptacle until you hear the connector click into place. Use only enough force to engage the connector in the receptacle no more than 3.5 lbs. This will avoid damage to the transceiver. 112 APPENDIX D: CABLING R EQUIREMENTS Multi-mode Fiber Standards The MMF-PMD standards define the requirements for an ATM cable plant to support an interstation distance of up to 2 kilometers (1.25 miles) of multi-mode fiber. The cable plant includes all fiber optic components between any two communicating ATM devices and their associated “station-to-network” connectors at each end. To determine whether the cable plant complies with the MMF-PMD standard, do the following: 1 Compare the specifications of the fiber you are using to standard specifications, as described in Table 25 and Table 26. 2 If unlike fibers are mated in the cable plant, calculate insertion losses to see whether they exceed the maximum attenuation value allowed for a link, as described in Table 27 and Table 28. 3 Verify that the fiber's modal bandwidth is within an acceptable range for the length of the link, as described on page 115. The following sections describe each of these steps and give examples. Comparing Fiber to Specifications Compare the specifications of the fiber you are using to those in the following tables. If the fiber does not meet the specifications, use a different fiber or contact 3Com's Technical Support. The fiber you use must meet the specifications listed in Table 25, which describes the standard set forth in MMF-PMD. Table 26 describes 62.5/125 cable, commonly sold as “ATM Spec,” which meets all the requirements of the MMF-PMD standard. Table 25 Standard Multi-mode Fiber Specification Specification Description Core 62.5 µm diameter Cladding 125 µm diameter nominal 122 µm minimum 128 µm maximum Numerical aperture 0.275 Maximum attenuation 11 dB* (1dB allowed for reflection and dispersion penalties.) Modal bandwidth 500 MHz. km ATM Cabling 113 Table 25 Standard Multi-mode Fiber Specification (continued) Maximum distance between nodes 2 km Output power (from transmitter) 19 dB minimum 14 dB maximum Receive power 30 dB minimum sensitivity 14 dB maximum sensitivity *Maximum attenuation includes cable attenuation and the loss induced by other components such as connectors, splices, and the mating of unlike fiber types. Although some 2 km cable plants have a total attenuation of less than 11.0 dB, the 2 km interstation distance must be maintained to comply with modal bandwidth requirements. Table 26 Alternate Multi-mode Fiber Types Calculating Insertion Losses for Unlike Fibers Core (µm) Cladding (µm) Numerical Aperture 50 125 0.20 50 125 0.22 85 125 0.28 100 140 0.29 If unlike fibers are mated in the cable plant, calculate insertion losses to be certain that the cable plant does not exceed the maximum attenuation value listed in Table 25. To calculate the insertion loss, consider the types of fiber in the cable plant and the connectors or splices used to join them. Compare the result to the maximum attenuation value listed in Table 25. If the result is greater than the value in the table, use only like fibers in the cable plant. Refer to Table 27 for the insertion losses of the fibers themselves. Use Table 28, which lists the losses for connectors, cables, and splices, if the specifications for these components are not available. Use Table 27 for fiber-to-fiber connections only, not for power launched from a transmitter. 114 APPENDIX D: CABLING R EQUIREMENTS Table 27 Insertion Losses for Mating Unlike Fiber Types - Transmitting Fiber Receiving Fiber Size Numerical Aperture 50 µm 50 µm 62.5 µm 85 µm 100 µm 0.20 0.22 0.275 0.26 0.29 50 µm 0.20 0.0 0.4 2.2 3.8 5.7 50 µm 0.22 0.0 0.0 1.6 3.2 4.9 62.5 µm 0.275 0.0 0.0 0.0 1.0 2.3 85 µm 0.26 0.0 0.0 0.1 0.0 0.8 100 µm 0.29 0.0 0.0 0.0 0.0 0.0 Table 28 Typical Losses for Typical Connectors, Cables, and Splices Type of Insertion Loss SC connector .6 dB ST connector (ceramic) .6 dB ST connector (plastic) 1.0 dB ST connector (stainless steel) .7 dB 62.5/125 cable 1.0 to 3.0 dB maximum per km, depending on cable quality (nominal 2.0 dB) 8/125 cable .5 dB/km (AT&T Lightguide) Bypass switch (currently not available in single mode) 2.5 dB maximum Fusion splice 1 to 3 dB depending on type used (use .3 dB) Example Suppose that a link consisting of one km of 62.5/125 fiber with a maximum attenuation rating of 1.75 dB/km is transmitting into one km of 50/125 fiber with a maximum attenuation rating of 3 dB/km. The fibers are joined using a fusion splice rated at 0.3 dB and the link contains one in-line ST connector rated at 0.6 dB. The following calculation would arrive at the link loss attenuation value for this linked fiber: 62.5µm cable loss + 50µm cable loss + splice loss + ST con+ insertion = Total link nector loss loss* attenuation 1 km(1.75 dB/km) +1 km(3 dB/km) +0.3 dB +0.6 dB * for mating unlike fiber types +2.2 dB =7.85 dB ATM Cabling 115 Because the resulting value, 7.85, does not exceed the maximum attenuation value, no adjustments are needed in the types of fibers joined or how they are connected. The link meets all of the specifications of the MMF-PMD. Verifying Modal Bandwidth The bandwidth of an optical fiber is the lowest frequency where the magnitude of the baseband frequency response has decreased by 3 dB compared to the magnitude at zero frequency. Bandwidth for multi-mode fiber is referred to as modal bandwidth because it varies based on the modal field (or core diameter) of the fiber. Modal bandwidth is specified in units of MHz • km, which indicates the amount of bandwidth supported by the fiber for a one km distance. The modal bandwidth specified in Table 25 is 500 MHz • km, which allows the cable plant to support end-to-end bandwidth of 250 MHz at the maximum 2 km distance. As a check, use the following formula to verify that the bandwidth of the fiber is within an acceptable range: n MHz • km / xkm = y MHz In this formula, n is the amount of bandwidth available according to the fiber specification. Divide this number by the total length x of the fiber in kilometers. The result is the modal bandwidth y, measured in MHz. If the result is lower than 250 MHz, the link may increase bit errors. To reduce the likelihood of bit errors, shorten the length of the fiber or use different fiber until the result of the calculation reaches 250 MHz. Example. Cable with a modal bandwidth of 500 MHz • km will have 250 MHz of bandwidth at 2 km: (500 MHz • km) / 2 km = 250 MHz The same cable would have 500 MHz of bandwidth at 1 km. A fiber cable with a bandwidth specification of 200 MHz • km would have only 100 MHz of bandwidth at 2 km, which would not support ATM. In this case, another type of fiber would be required. Single Mode Fiber Standards The SMF-PMD standard defines the requirements for an ATM cable plant to support a connection distance of up to 14.4 kilometers (8.6 miles) of single mode fiber. The cable plant includes all fiber optic components 116 APPENDIX D: CABLING R EQUIREMENTS between any two communicating ATM devices and their connectors at each end. To determine whether the cable plant complies with the SMF-PMD standard, do the following: 1 Compare the specifications of the fiber you are using to standard specifications, as described in Table 29. 2 If you mix equipment supporting Category 1 and Category 2, verify the maximum attenuation between the equipment, as described in Table 30. The following pages describe each of these steps and give examples. Comparing Fiber to Specifications Compare the specifications of the fiber you are using to those in Table 29. If the fiber does not meet the specifications, use a different fiber or contact 3Com Technical Support. The single mode PMD specification (SMF-PMD) defines two optical power categories: Category 1 and Category 2. These categories refer to the optical power that must be launched into the fiber by the transmitter or detected by the receiver. 3Com currently supports only Category 1 single mode fiber. The specifications for the standard single mode fiber are listed in Table 29. Refer to the Category 1 specifications in this table for fiber connecting 3Com equipment. For fiber used with Category 2 equipment from another vendor, refer to the Category 2 specifications. The cable plant for a Category 2 implementation must have a minimum loss of 15.0 dB. In a Category 2 implementation, minimum cable plant losses are required to avoid saturating (blinding) the receiver. Table 29 Single Mode Fiber Specifications Category Specifications Descriptions Both Categories Core 8 to 10 µm Cladding 125 µm (±2 µm) ATM Cabling 117 Table 29 Single Mode Fiber Specifications (continued) Category 1 Output power 14 dB minimum (from transmitter) 8 dB maximum Receive power 32 dB minimum 8 dB maximum Maximum distance* between ATM devices Category 2*** 14.4 km Maximum attenuation** 10 dB (1 dB allowed for reflections and dispersion penalties) Output power 4 dB minimum (from transmitter) 0 dB maximum Receive power 37 dB minimum 15 dB maximum Maximum distance* between nodes Maximum attenuation** 58.6 km 32 dB (1 dB allowed for reflections and dispersion penalties) * Maximum distances assume cable with one splice every 2.2 km with 0.3 dB loss each, and with no patch panels or mechanical splices. ** Maximum attenuation includes cable attenuation and the loss induced by other components such as connectors, splices, and the mating of unlike fiber types. ***Category 2 based on FDDI information, no ATM specific information yet. 118 APPENDIX D: CABLING R EQUIREMENTS Verifying Maximum Attenuation for Mixed Fibers If you mix Category 1 and Category 2 receivers and transmitters, use Table 30 to verify the maximum attenuation for each possible combination. Table 30 Acceptable Cable Plants for Combination of Categories 1 and 2 Output Category Input Category Minimum Loss (dB) Maximum Attenuation (dB) 1 1 0.0 10.0 1* 2* 1.0 16.0 2 1 14.0 26.0 2 2 15.0 32.0 *This combination is dispersion-limited rather than loss-limited. The expected maximum length is approximately 35 km. Example. If a Category 2 transmitter is outputting to a Category 1 receiver, the maximum attenuation is 26.0. DS-3 Coax Cables Connect the CoreBuilder 7000 DS-3 interface by a 75 Ohm coaxial cable that complies with DS-3 standards. The maximum cable length is 450 feet. To connect the DS-3 interface: 1 Prepare two coax cables - one for Tx and one for Rx. You may want to mark the ends of the cables to identify them easily. 2 Connect both cables to the DS-3 BNC connectors on the CoreBuilder interface. Make sure to connect Rx and Tx cables according to what is indicated on the interface front panel. 3 Connect the two cables at the other end according to the opposite of the first connection Rx to Tx and Tx to Rx. Ethernet Cabling The Ethernet port of the CoreBuilder allows you to connect the CoreBuilder to an Ethernet network for Network Management Station (NMS) connectivity (such as Transcend™). The Ethernet port is a standard RJ-45 connection of a terminal side. Follow these guidelines for 10BASE-T cabling: ■ Use only copper, unshielded twisted-pair (UTP) wiring. Do not use flat, multiconductor cable (for example, silver satin), which is often identified by solid colors such as red, green, yellow, or black. Ethernet Cabling Cable Pinouts 119 ■ Use two twisted-pairs for each link. ■ Use twisted-pair wire that is 22-26 AWG (0.5 millimeter) in diameter. ■ Use twisted-pair wire with an impedance between 85 and 115 ohms. ■ Make sure that the maximum twisted-pair link length from the system to any potential workstation location is 100 meters (328 feet). Management connections may be established with a direct cable link to a PC-AT serial port, or via modem. The following tables detail cable pinouts for 9 and 25 pin PC-AT links, and for a modem connection. CoreBuilder 7000 Serial Port The CoreBuilder 7000 provides a standard DB-9 connector for management connections (refer to Figure 17). Table 31 details the pinout and functions for this connector. The CoreBuilder 7000 plays the standard role of a DCE.
