Chapter 1 Introduction 1-1 Terabeam Gigalink Field Installation and Service Manual Document Number: 045-1032-0000 / Revision: Draft Release Date: TBD / Print Date: 12/10/02 Proprietary and Confidential 1 Introduction Gigalink Product Family The Terabeam® Gigalink millimeter wave radio system represents an entirely new approach to broadband communications. Based on our extensive experience with millimeter wave systems for military and research applications, we now apply these techniques to a commercially priced version with our ultra-broadband family of Gigalink radio products. The Gigalink broadband radio system operates in the FCC Part 15.255 unlicensed band covering a frequency range of 57.05 – 64.0 GHz. Due to the unlicensed status of this band, FCC license or special authorization is not required to operate our Gigalink systems. In addition, the high atmospheric absorption of RF energy at this frequency virtually eliminates any chance of interference from competing systems or unauthorized interception of the broadcast signal. The installation procedures detailed within this guide are similar to those used to install any wireless system. In fact, certain attributes of the 57.05 – 64.0 GHz band actually simplify deployment. The key to any successful installation project is proper planning and design. The Gigalink radio product has been designed for ease of installation and trouble-free operation. We recommend that you read and fully understand this guide prior to initiating the actual installation work. As stated above, the key to successful installation is proper system planning and execution. As with most wireless systems, the Gigalink radio system requires un-obstructed Line of Sight (LOS) to operate reliably. Because of the extremely high data bandwidth provided by the Gigalink system (1.25Gbps) it is likely that our radio systems will be utilized as a critical or primary network connection. This absolute reliance on our systems for connectivity demands a focused attention to detail in order to assure un-interrupted operation. Reliability All Gigalink products are designed to provide a minimum statistical path availability of 99.99% (BER < 1 x 10 –9) when operated within the recommended range envelope. Exceeding the specific model range restrictions will result in unreliable operation particularly during adverse weather. Statistical availabilities in excess of 99.99% may be achieved by choosing the next longer range system for a given path or by co-locating two Gigalink systems. Traditional circuit redundancy methods utilizing collapsible ring architectures or media diversity may also increase statistical availability.

Terabeam recommends that two technicians with monitor-enabled laptops be dedicated to this task. By dedicating two technicians equipped with cellular phones or two-way radios, final alignment can be accomplished at both terminal sites concurrently, eliminating the need to constantly travel between sites. Radio Terminal Power-Up Once the Radio terminals have been mechanically mounted in place and visually aligned, both radio terminals must be powered up, and network services connected. Terminal Power up Power-up the Gigalink terminal as follows. 1. Attach DC power cord securely to the radio terminal 2. Attach power leads to –48VDC source Red to –48VDC supply, Black to –48VDC return and Green to Building Ground. 3. Power up –48VDC circuit. 4. Verify power on condition via Green “Power-on” LED’s located on the bottom of the terminal housing Connecting Network Services Once the power has been applied to the Gigalink terminal, Network services can be connected and verified. The network Fiber connections to the Gigalink terminal are Type FC male terminated fiber optic cables. Make these connections by aligning the connector body index tab, then tightening the outer collar in a clockwise rotation. In the network switch room, insert the other end of each fiber optic cable into the appropriate TX and RX switch ports. If done correctly, a link light should be visible. If no link light is visible, make sure the radio is powered up and swap the fibers.

From the “Action” Menu select “Align” then “Run” Figure 16, Gigamon in “Alignment Run” Mode When in the “Align”, “Run” mode the Gigamon monitor displays a continually updated receive level. The task during precision alignment is to maximize or peak the receive level. Precision alignment is made in both the vertical and horizontal plane (up and down, left and right) separately, one terminal at a time. Begin alignment by aiming the radio terminal slowly up while observing the change in receive level. Typically, the receive level will rise, then fall and then rise again slightly on both sides of the optimum alignment as the receiver moves from the center main beam to the edge side-lobes of the radiation pattern. It is recommended that the technician move the alignment through the main lobe and into both side-lobes until returning to the center peak Highest Receive level achieved (magenta band) Blue Bar Indicates Current Receive Level

When satisfied that the maximum receive level has been reached, tighten the Gimbal side adjuster bolts to hold the desired vertical alignment angle. To facilitate this task, Gigamon displays the highest receive level recorded as a magenta bar at the top of the receive level bar. Repeat this procedure for the Azimuth (Horizontal) alignment by slightly loosening the Gimbal base mounting bolts and rotating the alignment from right to left. Again, by observing changes in the receive level monitor, identify both side-lobe areas and return the alignment to the center “Peak” position. Repeat the previous two alignment procedures at the other Gigalink terminal while maintaining the position of the original terminal. During these procedures, the receive level should continuously improve. Optimum terminal alignment is best accomplished by small adjustments at both terminal sites. NOTE: Precision alignments are made most easily by make very slight incremental adjustments to the radio alignment. Care must be taken not to over-adjust the alignment. To facilitate precision alignment, tighten all adjusting bolts to allow movement only when bumping terminal firmly with your hand. An acceptable receive level will be indicated by the Blue Gigamon receive level indicator as a level approaching the Maximum recorded receive level (Magenta line) and as a level falling somewhere in the upper half of the green region behind the blue indicator bar. An acceptable numeric measure would be a level above 450 as indicated by the large level number displayed below the receive level indicator. When satisfied that optimum alignment has been achieved, tighten the (3) Gimbal base mounting bolts and the (4) Gimbal side adjuster bolts to secure the desired position. As a final installation step, perform the “Save GigaMon Information in a File as” operation as prompted when exiting the application. The saved radio parameter information can be used for future comparisons to gauge ongoing radio performance. Verifying Network Operation Once an acceptable (optimum) receive level has been achieved, the Gigalink system will provide an error free RF link between the two network devices at both sites. If no link is obtained, check the network fiber, routing table configurations and other network parameters. If an error free link still cannot be established, consult the Troubleshooting/Diagnostic section of the Gigalink User’s Manual.

Gigamon will detect and read the parameters of multiple Gigalink terminals (up to 8) at the same time, but it configures/monitors only the Gigalink currently selected. After selecting ‘Refresh’ from the ‘Action’ menu, the first Gigalink detected becomes the currently selected; all the components of the main window display the parameter values of the currently selected Gigalink terminal. The user can select another Gigalink terminal by clicking on option “Select Gigalink” in “File” menu and selecting that terminal from the list displayed.
Chapter 3 Gigamon Software 3-3 Terabeam Gigalink Field Installation and Service Manual Document Number: 045-1032-0000 / Revision: Draft Release Date: TBD / Print Date: 12/10/02 Proprietary and Confidential Before going into the operating details, some terminology, and the color convention used should be explained. Terminology • ‘Monitoring’ is an action state defined as ‘Runmode’/’Alignment’ and/or reading current Gigalink terminal parameters. ‘Runmode’ is the state where Gigamon reads the Gigalink terminal parameters (specially for Rx Power/Receive Level) while continuously updating the display. • ‘Setting Network Parameters” ,“Setting Threshold Parameters” and “Setting Factory Parameter” are all part of “Configuring Gigalink”. Setting a parameter means saving that value in Gigalink terminal’s EEPROM image, once saved the terminal will keep the new values even if Gigalink terminal is powered off and back on. Color Convention The status colors of the Gigamon display are: • Black Unknown • Green Safe range/On/Running • Red Danger range/Off/Stopped • Yellow Warning range • Blue Current/Latest read Value • Grey Read-Only Components of the Main Window • MAC Address: The MAC or Hardware address off the Gigamon utility resident in the Gigalink terminal. This unique address is set at the factory and cannot be changed. Initially the Gigamon program does not know this MAC address of the connected Gigalink(s), and so the value “Unknown” is displayed. When ‘Refresh’ is selected from Action menu, the program tries to get the MAC addresses of all the Gigalink terminals connected to the network segment, and then ‘Unknown’ value becomes the MAC address of the first Gigalink terminal MAC address detected. By default, the first Gigalink terminal detected during refresh becomes the “Currently Selected” Gigalink. • Serial Number: This value is set at the factory and cannot be changed. The value displayed, also corresponds to the currently selected Gigalink.
3-4 Chapter 3 Gigamon Software Terabeam Gigalink Field Installation and Service Manual Document Number: 045-1032-0000 / Revision: Draft Release Date: TBD / Print Date: 12/10/02 Proprietary and Confidential • Synthesizer, PLL, TX Link, and RX Link: These are discrete values that indicate an acceptable or unacceptable state for critical monitoring points within the Gigalink radio terminal. The rectangles associated with the Synthesizer and PLL Lock display green if they are locked (acceptable), or display red if unlocked (unacceptable). The rectangles for Tx Link and Rx Link are green if an optical signal is present on the fiber segment, and turn red if no signal is present. • Rx Power: In “Align/Run” mode, the blue rectangle represents current Receive Level. If ‘Run’ is chosen from the ‘Align’ submenu of ‘Action’ menu, it starts displaying this value continuously. A higher Rx Power indicates better alignment. As the user does adjustment in “Run” mode changing the Gigalink terminal alignment, Rx Power varies. A magenta, horizontal, line is displayed on the top of the blue receive level rectangle indicates the highest/maximum value reached so far. A numeric value of the maximum receive level is displayed adjacent to the magenta line. The blue inner rectangle represents the current value. The current Rx Power’s numeric value is also shown below the rectangle in a large font to facilitate alignment with higher visibility. • 6 Volt, 15 Volt, -15 Volt, Vtune, Gunn: These are other variable values. During ‘Refresh’ and ‘Run’, Gigamon retrieves the current values and displays these values as a blue horizontal line. These rectangles are divided into safe, warning and danger regions. If the current value is the optimum then the blue line should be at the middle. For 6 Volt rectangle, the optimum value is 6.10, top to middle, or bottom to middle is the 10% of optimum value, and so, for 6 volt top=6.1+(0.61*1)=6.71, and bottom=6.1-(0.61*1)=5.49. For all others, top to middle, or bottom to middle is 40% of the optimum value. So for 15 Volt, the optimum value is 15.0, top=15.0+(1.5*4)= 21.0, bottom=15.0-6.0=9.0. The optimum values of –15 Volt, 24 Volt and Gunn are 15.0, 24.0, and 850 respectively. • Status bar: The status bar at the bottom of the screen is for displaying current status, error, and some numeric values. Errors and status are shown at the left, and values at the right. Most importantly, during refresh, it shows the numeric value of all variable parameters. • Menu: 1. File Menu: The ‘File’ menu has following options: − ‘Select Gigalink’ to open the “Select Current Radio/Gigalink” dialog box as shown below.
Chapter 3 Gigamon Software 3-5 Terabeam Gigalink Field Installation and Service Manual Document Number: 045-1032-0000 / Revision: Draft Release Date: TBD / Print Date: 12/10/02 Proprietary and Confidential “Select Current Radio/ Gigalink” Screen The “Select Current Radio/Gigalink” window displays the factory-set parameters of the currently selected/active Gigalink at the top and a combo box (list) of MAC addresses for all the Gigalink terminals found. Choosing a different MAC address from the combo list updates serial number field with corresponding value for that terminal. If ‘Select’ and then ‘OK’ buttons are pressed then Gigamon selects only the radio with the MAC address currently selected in “Gigalink Radio MAC Address” combo box as the currently selected/active Gigalink. Pressing ‘Cancel’ button after ‘Select’ undoes the selection and keeps previous selection of currently active radio. − ‘Save Info As’ to open a dialog box “Save Gigalink Info in a File As” for the user to select a text filename to save all the parameters for all the Gigalink terminals detected.

It also shows the current (Factory default) values of the following SNMP related settable/configurable parameters: − Gigalink SNMP Agent IP: This value is needed for any SNMP monitoring software to request a Gigalink for any SNMP variable’s value or to change value (SNMP Get/Set functions). It is also needed for SNMP monitoring software to distinguish the source of any SNMP trap packet sent by any Gigalink terminal. It may also be required for many other network activities like pinging a Gigalink terminal since this communication protocol uses IP packets. An IP-Address/Net-Mask consists of 4 octets separated by dots and each octet’s range is 0 to 255.
3-10 Chapter 3 Gigamon Software Terabeam Gigalink Field Installation and Service Manual Document Number: 045-1032-0000 / Revision: Draft Release Date: TBD / Print Date: 12/10/02 Proprietary and Confidential − Subnet Mask, and Gateway IP: These parameters define which IP address range will be local for the Gigalink terminal. When the Gigalink terminal sends an IP packet, it does logical AND between this Subnet Mask and destination IP address to find out if the destination is in its local subnet. The Gigalink terminal needs to know the local “Subnet Mask” because if the destination is not within its local network, the Gigalink terminal will send the packet to the default destination, the Gateway, which is a router. For this reason, the Gateway/router’s IP address must be defined as well. − SNMP Manager IP: The Gigamon user must define the IP address of the computer/host acting as SNMP Manager so that Gigalink terminal can send SNMP traps to the host. − Report Frequency: The Gigamon user must define how frequently each radio terminal will send SNMP trap packets to the SNMP Manager reporting the status of the SNMP variables. The combo box gives list of report intervals to choose from. If ‘Unknown’ is chosen, pressing ‘Apply’ button will send the new parameter values to the currently selected Gigalink and write that value into Gigalink terminal EEPROM image. − SNMP ‘Get’/’Set’ Operations: The parameters 'Community String', 'Net' and 'Mask' ensure security of the SNMP 'Get'/'Set' operations. The Gigalink matches the 'Community String' in the SNMP manager's 'Get'/'Set' request packet, and also checks if the SNMP manager's IP address is within the range that is defined by 'Net' and 'Mask'. If any of these validations fail, the Gigalink terminal will not respond to the request. 'Community String', 'Net' and 'Mask' can be different for 'Get' and 'Set' operations. − Community string: The “Community String” is like a password for the SNMP 'Get'/'Set' operation. If a community string is set, then the SNMP manager needs to provide it to the Gigalink terminal if sending 'Get'/'Set' request. When the Gigalink terminal receives a request, it will match this string. If the match fails, the Gigalink terminal will not send requested parameter(s) values back to the SNMP manager on 'Get' request, and will not change its parameter values on 'Set' request. This string must be alphanumeric and no longer than 16 characters. − Net and Mask: These two parameters define the range of IP addresses acceptable to the Gigalink terminal when responding to SNMP 'Get'/'Set' requests. The format is x.x.x.x where x is a digit from 0 to 255. For example, if 'Net' is defined as 10.0.0.0 and 'Mask' as 255.255.255.0, then the range of IP addresses the Gigalink terminal will accept is 10.0.0.x where x = 1.254.

This is used for initializing the above parameters at the Harmonix factory. − The ‘Threshold and Trigger’ option from ‘SNMP’ submenu of ‘Settings’ menu opens the dialog box “Triggering Parameters and Setting Thresholds”. “Triggering Parameters and Setting Threshold” Screen These settings trigger parameters on/off and define the threshold range for the triggered parameters. The Gigalink terminal monitor will send the SNMP Host/Manager an SNMP alert trap when a trigger-enabled parameter goes beyond the set threshold range. Checking an item’s box will activate that parameter to be monitored against threshold ranges or an on/of condition. When the ‘Apply’ button is clicked the setting is written to the Gigalink terminal EEPROM. The description of each parameter and their corresponding threshold values are given below.

Enter ‘Low’ for low threshold ranging (5.6 to 6.1), and enter ‘High’ for high threshold ranging (6.1 to 6.5). The optimum value is 6.1 volt. • +15 Volt: A power supply voltage. Enter ‘Low’ for low threshold ranging (10 to 15), and enter ‘High’ for high threshold ranging (15 to 20). The optimum value is 15.0 volt. • –15 Volt: A power supply voltage. Enter ‘Low’ for low threshold ranging (10 to 15), and enter ‘High’ for high threshold ranging (15 to 20). The optimum value is 15.0 volt. ‘-15’ is only the name of this parameter, and all threshold values related to this parameter are set positive. • VTune: Varactor tuning diode voltage. Sampling this voltage provides another monitoring point for transmitter source stability. Vtune will typically fall between 4 and 7 Volts and may vary slightly during normal operation. Wide variations in varactor voltage beyond the initial reading may indicate a tuning problem with the fundamental GUNN diode oscillator source. The Vtune parameter does not offer a default threshold setting option nor will it trigger an alarm trap in response to changes to this reading. • Gunn: The Gunn Oscillator current. Enter ‘Low’ for low threshold ranging (590 to 850), and enter ‘High’ for high threshold ranging (850 to 1300). The optimum value is 850 milliamps. • Rx Power: The receive level. Enter ‘Low’ for low threshold ranging (300 to 600), and enter ‘High’ for high threshold ranging (600 to 1000). • Tx Link: Transmit Link. If it is triggered on and optical circuit becomes open, SNMP alert trap will be sent. • Rx Link: Receive Link. If it is triggered on and no data is coming to Gigalink from the corresponding remote terminal, SNMP alert trap will be sent. • PLL, and Synthesizer: If the ‘PLL’ or ‘Synthesizer’ is not locked, one of the Gigalink terminal’s fundamental frequency generating device is operating improperly. If these parameters are triggered on, and an SNMP alert trap will be sent. The ‘Defaults’ button sets all the default triggers and threshold values. After getting default values, one still needs to press ‘Apply’ button to write the values to Gigalink. The ‘Action’ menu contains the following commands:

All connected Gigalink(s) reply with the data requested along with their MAC address. Gigamon can receive replies from up to 8 Gigalink terminals and refreshes its data discarding any old data of the current session if there is any unless any data was saved through the menu option “Save Gigalink Info As” from ‘File’ menu before current ‘Refresh’ action. After receiving the reply(s) the refresh command will open the “Refreshed Gigalink Information” dialog box. “Refreshed Gigalink Information Screen” The “Refreshed Gigalink Information” dialog screen is divided into 3 sections. The upper left group shows Gigalink factory set, read-only parameters. The group “SNMP Network Parameters” at the lower left shows the values used for SNMP connection/configuration and can be changed by menu option ‘Settings’->’SNMP’->’Network’. The group “SNMP Threshold Parameters” on the right shows each parameter, its values, which define threshold condition and whether it is enabled or not.
