There are two ways you can do this:■Use SSH to Set the ZoneDirector IP Address on the CMAP■Configure Option 43 on the DHCP Server (ZoneDirector Management Only)
15Preparing for InstallationPointing the CMAP to ZoneDirectorUse SSH to Set the ZoneDirector IP Address on the CMAPYou can use SSH to set the IP address of the ZoneDirector device that you want to use to manage the CMAP. Before starting this procedure, you must obtain the IP address of the ZoneDirector device to which you want to assign the CMAP.To perform this procedure, you will need the following:■An administrative computer■An Ethernet cable■A Telnet or SSH (secure shell) client programTo set the ZoneDirector IP Address on the CMAP via SSH1. Connect one end of the Ethernet cable to the administrative computer’s Ethernet port, and then connect the other end to the CMAP’s Ethernet port.2. Change the administrative computer’s IP address to the same subnet as the CMAP. The AP’s default IP address is 192.168.100.2.3. Start the Telnet or SSH client program on the administrative computer.4. Log onto to the AP via Telnet or SSH using the following logon details:•User name: super•Password: sp-admin5. When command prompt appears, enter the following command:set director ip {ip-address}where {ip-address} is the IP address of the ZoneDirector to which you want to assign the CMAP.The following message appears, which indicates that you have assigned the ZoneDirector IP address:Please reboot for this change to take effect.6. Reboot the CMAP.7. Log onto the command prompt again, and then enter the following command:get director infoThe command prompt displays the IP address of the ZoneDirector device that is managing the CMAP.8. Verify that this IP address is the same IP address that you set in Step 5.You have completed the setting the ZoneDirector IP address via SSH.
16Preparing for InstallationPointing the CMAP to ZoneDirectorConfigure Option 43 on the DHCP Server (ZoneDirector Management Only)You can configure the DHCP server on your CMTS backbone to ensure that the CMAP will successfully discover its parent ZoneDirector on the network.To customize your DHCP server, you need to configure DHCP Option 43 (043 Vendor Specific Info) with the IP address of the ZoneDirector device on the network. When an access point requests an IP address, the DHCP server will send a list of ZoneDirector IP addresses to the access point. If there are multiple ZoneDirector devices on the network, the access point will automatically select a ZoneDirector to register with from this list of IP addresses. NOTE: The following procedure describes how to customize a DHCP server running on Microsoft Windows. If your DHCP server is running on a different operating system, the procedure may be different.The procedure for configuring Option 43 on your DHCP server depends on whether both ZoneDirector and FlexMaster exist on the network, and whether you want to add the DHCP subcode for ZoneDirector.If Only ZoneDirector Exists on the Network (No ZoneDirector Subcode)1. From Control Panel > Windows Administrative Tools, open DHCP, and then select the DHCP server you want to configure.2. If the Scope folder is collapsed, click the plus (+) sign to expand it.3. Right-click Scope Options, and then click Configure Options. The General tab of the Scope Options dialog box appears.4. Under Available Options, look for the 43 Vendor Specific Info check box, and then select it.5. Under Data Entry, position the cursor in the ASCII text area, and then type the IP address of the ZoneDirector device. In the figure below, the IP address of the ZoneDirector device is 192.168.100.2.
17Preparing for InstallationPointing the CMAP to ZoneDirectorFigure 9. In the ASCII area, type the IP address of the ZoneDirector deviceThe hexadecimal equivalent of the ZoneDirector IP address appears in the Binary text area.NOTE: If there are multiple ZoneDirector devices on the network, type all the IP addresses in the ASCII text area. Use commas (,) to separate the IP addresses. If a management interface is used for Web UI management, the actual IP address must still be used when configuring ZoneDirector as a client for a backend RADIUS server, FlexMaster server or in any SNMP systems. If two ZoneDirector devices are deployed in a Smart Redundancy configuration, both of the actual IP addresses must be used rather than the management IP address.6. Click Apply to save your changes.7. Click OK to close the Scope Options dialog box.You have completed customizing your DHCP server to automatically provide supported APs with ZoneDirector’s IP address.
18Preparing for InstallationPointing the CMAP to ZoneDirectorIf Only ZoneDirector Exists on the Network (With ZoneDirector Subcode)1. From Control Panel > Windows Administrative Tools, open DHCP, and then select the DHCP server you want to configure.2. If the Scope folder is collapsed, click the plus (+) sign to expand it.3. Right-click Scope Options, and then click Configure Options. The General tab of the Scope Options dialog box appears.4. Under Available Options, look for the 43 Vendor Specific Info check box, and then select it.5. Under Data Entry, highlight the existing values, and then press <Delete> on your keyboard.6. Position your cursor again after the last octet (in this example, 0000) under the Binary text area, and then type 03 (the subcode for ZoneDirector).Figure 10. Under the Binary text area, type 03 (the subcode for ZoneDirector)7. After the ZoneDirector subcode (03), type the hexadecimal equivalent of the length of the ZoneDirector IP address. For example, if the ZoneDirector IP address is 192.168.10.1, the length in decimal is 12 and the hexadecimal equivalent is 0B.
19Preparing for InstallationPointing the CMAP to ZoneDirectorFigure 11. After the ZoneDirector subcode, type the hexadecimal equivalent of the ZoneDirector IP address length8. Position the cursor under the ASCII text area, and then type the ZoneDirector IP address.

The other two connectors are located on the other side of the unit (see Figure 20).DC Connector In addition to the power supplied by the coaxial cable from the CMTS, the CMAP may also be DC powered. Shorting pins 3 and 4 in the DC power connector using an electrical shunt will reset the CMAP to factory default settings. For more information, refer to “Troubleshooting” on page 46.Coaxial Cable Connector AProvides a 9 dB lower sample of the downstream RF signal as seen by the modem electronics. Therefore, the CATV tap should be selected to provide a measured downstream signal level on this port, which is approximately 12 to 20 dBmV in the channel being used.Coaxial Cable Connector BConnects to the cable modem termination system (CMTS) at the headend using a tap on the plant and it provides AC power to the CMAP. AC power is supplied via Power Over Cable (POC). For more information, see “Using Power Over Cable (Actual Deployment)” on page 35.

31Hardware FeaturesConnectorsConnectorsThe CMAP provides the following connectors:■PoE-Out connector: RJ-45 port that can supply power to devices that support PoE.■Three N-type antenna connectors: Connects to the three 5GHz antennas supplied with the CMAP.■DC power supply (Ruckus Wireless part number 705-60244-002): Connected through a 4-pin connector, which is normally unused. It may be used to supply DC power to the unit for testing or configuration purposes. The supply has a reset switch that may be used to reset the unit. See “Using the Reset Switch on the DC Power Supply” on page 40 for more information.■Coaxial cable connectors (see Figure 19): Connector A may be connected to a spectrum analyzer or signal analyzer to allow monitoring of the downstream signal. Connector B must be connected to the CMTS backbone and AC power when deployed in the field.Ethernet/PoE-Out PortThe CMAP provides one 10/100Mbps RJ45 Ethernet port, which also functions as a PoE-Out port. The PoE-Out port, which can supply up to 15.4 watts (compliant with 802.3af), can be used to power PoE-capable devices (for example, an IP-based surveillance camera). NOTE: The PoE-Out function is non-operational when the unit is powered via the 12 VDC connector.NOTE: By default, both Ethernet data and PoE-Out are enabled. If necessary, you can disable PoE-Out from the Web interface. Refer to the AP User Guide for more information. LEDsUse the six LEDs to check the status of the access point and cable modem. The LEDs behave differently when the access point is in standalone mode and when ZoneDirector is managing it.Upon bootup, the LEDs are in CM Mode. Once bootup is completed, the LEDs alternate between CM Mode and AP Mode.NOTE: The LEDs do not indicate whether the access point is in standalone mode or if ZoneDirector is managing it. To check if ZoneDirector is managing the access point, log into the ZoneDirector Web interface, go to the Access Points page, and then search for
32Hardware FeaturesLEDsthe access point’s MAC address. If you are unable to find the access point, then it is very likely to be in standalone mode. If you have multiple ZoneDirector devices on the network, make sure you check each one of them.Tabl e 9 describes the behavior of the LEDs on the CMAP when it is in CM, AP standalone, and AP ZoneDirector modes.Table 9.

33Before You BeginSupported Power SourcesSupported Power SourcesThe CMAP supports the following power sources:■Power over Cable (POC): 40 to 90V AC supplied through the RF coaxial cable (attached to Connector B) that is connected to the cable modem termination system (CMTS) backbone. POC is the primary and conventional source of power for the CMAP.■DC power (via DC connector): External 12 VDC. Use this only when staging or debugging the CMAP. NOTE: PoE output is disabled when the CMAP is powered via the 12 VDC connector.HeatersThe CMAP includes two built-in heaters that permit operation at extremely low temperatures. They are typically on below 0 degrees C.The heaters are enabled by default. If preferred, the access point heater can be disabled from the Web interface. The cable modem heater cannot be disabled.5Before You BeginBefore installing and setting up the CMAP, Ruckus Wireless recommends that you first complete the following pre-installation tasks.Prepare the Required Hardware and ToolsYou must supply the following tools and equipment:■A notebook computer running Windows 7/Vista/XP with one wireless 802.11b/g/n network card and one Ethernet card installed■Coaxial cable with a male F connector (connected to the CMTS backbone)■If you plan to use DC to power the CMAP (for staging or debugging purposes only), you will need a DC power supply (see DC Power Supply in “Connectors” on page 31).NOTE: At the beginning of each procedure, this guide lists the specific tools, accessories, and equipment that you will need to complete the procedure.
34Before You BeginPerform a Site SurveyPerform a Site SurveyBefore installing the CMAP, perform a site survey to determine the optimal access point placement for maximum range, coverage, and network performance. When performing a site survey, consider the following factors:■Data rates: Range is generally inversely proportional to data rates. The maximum radio range is achieved at the lowest workable data rate. Higher data rates will generally be achieved at closer distances.■Physical environment: Clear or open areas provide better radio range than crowded or filled areas. The less cluttered the operating environment, the greater the wireless range.■Obstructions, building materials, and sources of interference: Physical obstructions, such as concrete pillars, steel beams, filing cabinets, buildings, or trees, can block or hinder wireless communication. Avoid installing the CMAP in an environment where there is an obstruction between sending and receiving devices. A number of machines and electronic devices that emit radio waves – wireless phones, microwave ovens, satellite dishes – interfere with and block wireless signals. Building materials used in construction also influence radio signal penetration. For example, drywall construction permits greater range than concrete blocks. ■Mounting: The CMAP is designed to hang on a 1/4 to 3/8" support wire. The hangers will allow a 2" bundle of cables between the support wire and the CMAP.■Power and backhaul connections: Of course, the CMAP needs a backhaul connection to the CMTS and it needs to be close enough to an AC power inserter on the CATV cable to assure that it will be able to pull 60 watts at greater than 45 VAC. If not, then another power inserter must be installed closer to the CMAP. The CATV signal level must be roughly 5 dBmV at the tap connection to the unit.
35Powering the CMAPUsing DC Power (Staging or Debugging Only)6Powering the CMAPThe CMAP supports both POC (AC) and DC power. Depending on whether you are have access to 45 to 90 VAC on the CMTS CATV cable or would prefer to power it with 120-240 VAC and a 12 VDC adaptor, follow the relevant procedure below.Using DC Power (Staging or Debugging Only)Use DC power to supply power to the CMAP only when you are staging or debugging the device in a lab environment. When performing the actual deployment of the CMAP, you must use POC (see “Using Power Over Cable (Actual Deployment)” in the next section).To supply power to the CMAP using DC power1. Obtain a DC power supply (see DC Power Supply in “Connectors” on page 31).2. Connect the DC power supply to the DC connector (shown in Figure 19).3. Connect the DC adapter to a 120 -240 VAC source.You have completed connecting the CMAP to a DC power source. Using Power Over Cable (Actual Deployment)When performing actual deployment of the CMAP, you must use only POC via an F-type coaxial cable that is connected to the CMTS backbone.To supply power to the CMAP using POC1. Insert the F-type coaxial cable that is connected to the CMTS backbone to the F-type connector (Connector B) on the CMAP. Power is supplied through a power passing tap on the CATV coax. The tap is connected to Connector B on the CMAP.2. Finger tighten the coaxial cable connector and then tighten to the recommended torque specifications for the connector type that you are using.3. Verify that the CMAP is receiving power by checking if any of the LEDs is on.You have completed supplying power to the CMAP using POC.
36Verifying Access Point OperationUsing Power Over Cable (Actual Deployment)7Verifying Access Point OperationAfter powering the CMAP, you can verify that the access point is operating normally by associating a wireless client with it.NOTE: The following procedure uses a wireless client that is running on Windows. If using a wireless client that is running on a different operating system, refer to that operating system’s documentation for instructions on how to associate with an access point.To associate a wireless client with the AP1. Obtain a Windows computer with a built-in or external wireless card. 2. In the system tray, right-click the (Wireless Network Connection) icon, and then click View Available Wireless Networks. 3. In the list of available wireless network, click the network with the same SSID as you configured in “Step 4: Configure the Wireless Settings” on page 10. For example, if you set the SSID to Ruckus Wireless AP, click the wireless network named Ruckus Wireless AP.If ZoneDirector is managing the access point, the wireless settings would have been included in the configuration file that the access point downloaded when it registered with ZoneDirector. Check with your CMTS administrator and ask for the SSID that the access point has been configured with.4. Click Connect. Your wireless client connects to the wireless network. After the wireless client connects to the wireless network successfully, the wireless client icon in the system tray changes to .5. Verify that you can connect to the Internet by starting your Web browser, and then visiting http://www.ruckuswireless.com. If you are able to view the Ruckus Wireless web site, then your wireless client is able to successfully connect to the Internet through the access point.You have completed verifying the access point operation.8Switching LEDs to Cable Modem ModeThe LEDs indicate the statuses of both the access point and cable modem components. However, they can only show the status of one or the other at a time – either access point status only (AP Mode) or cable modem status only (CM Mode).
37Switching LEDs to Cable Modem ModeUsing the AP’s Web Interface to Switch to CM ModeWhen the access point boots up, the LEDs are in CM Mode. Once it completes the bootup process, the LEDs alternate between CM Mode and AP Mode. The LEDs are color-coded to enable you to quickly identify the current LED mode:■If you see an orange LED, the LEDs are in AP Mode.■If you see a white LED, the LEDs are in CM Mode.If you want the LEDs to stay in CM Mode, you need to manually switch them to CM Mode. You can switch to CM Mode through the following methods:■Using the AP’s Web Interface to Switch to CM Mode■Using SNMP to Switch to CM ModeUsing the AP’s Web Interface to Switch to CM ModeTo use the Web interface to switch the LEDs to CM Mode1.

44Mounting the CMAPUsing SNMP to Reset the Access Point11 Mounting the CMAPTo mount the CMAP assembly on a cable strand, you need to secure the cable clamps that are attached to the strand interface bracket to the cable strand.NOTE: The CMAP must be installed on a cable strand by a professional cable installer.The CATV coaxial cable used in the actual field deployment must have 45 to 90 VAC power multiplexed with the RF signal on the coaxial cable since Connector B is used for both electrical power and the RF signal.To mount the CMAP1. Slightly loosen the square nuts that fasten the two cable clamps to the strand bracket, enough for the strand support cable to fit into the cable clamps.2. Place the cable clamps on the strand support cable.3. Tighten the two square nuts to approximately 16 ft-lbs to secure the mounting.4. Connect the CATV connector from the cable lines to Connector B on the CMAP. Select a CATV power passing tap that will supply a signal level between -15 and +15 dBuV at its output (prefer 0 to 6 dBuV). Connect the CMAP's Connector B to the tap's output using an RG6 quad shield cable. NOTE: You may use the CMAP's loop-through function on Connector A to measure the downstream signal level at the internal cable modem. Connector A's signal level is approximately 9 dB lower than the signal at the input to the modem.You have completed mounting the CMAP on the cable strand. You may now install the three external antennas. See “Installing the Antennas” on page 45 for more information.
45Installing the AntennasUsing SNMP to Reset the Access Point12 Installing the AntennasAfter you mount the CMAP on the cable strand, the next step is to install the three 5GHz antennas that are supplied with the CMAP.CAUTION: To avoid damaging the antennas, Ruckus Wireless strongly recommends thatyou install the antennas only after you mount the CMAP on the cable strand and have attached the strand coaxial cable to Connector B. See the preceding section.To install the external antennas1. Take out the three antennas that were shipped with the CMAP.2. Locate the three N type female bulkhead connectors on the underside of the strand interface.3. Take one antenna and then mate its end (N type male connector) with the N type female bulkhead connector on the strand interface.4. Using your fingers, turn the connector nut only on the antenna to tighten the connection.5. Repeat the previous two steps for the two remaining antennas.6. Verify that all three antennas are securely attached to the strand interface.7. Verify that all antenna connectors from the strand interface are securely fastened to the CMAP.You have completed attaching the external antennas to the strand interface. NOTE: After verifying correct connections and correct operation, you may choose to wrap the connectors with self-fusing tape if you deem that they require protection from local weather.
46What to Do NextChange the Administrative Password13 What to Do NextThe following are some of the post-installation tasks that Ruckus Wireless recommends. Refer to the ZoneFlex 7761CM Dual Band 802.11n Outdoor Access Point with Integrated Cable Modem User Guide for more information on configuring and managing the access point.Change the Administrative PasswordManagement access to the Web interface of the access point is controlled through administrative user name and password. As soon as you complete the access point setup, make sure you log on to the access point’s Web interface and change the default administrative user name and password. This will help prevent unauthorized users from logging in to the access point’s Web interface and changing the access point settings to compromise your network.Read Related DocumentationIf you are using FlexMaster or ZoneDirector to manage the access point, make sure you read the accompanying documentation to learn how to configure and manage the access point from the FlexMaster and ZoneDirector Web interface. The latest versions of Ruckus Wireless access point documentation are available for download on the Ruckus Wireless Support Web site at:http://support.ruckuswireless.com/documents14 TroubleshootingThis section lists some information that may be useful in troubleshooting the CMAP. Topics discussed include:■Retrieving the CM’s MAC Address■How Radio Frequency Scanning Works■Contacting Ruckus Wireless SupportRetrieving the CM’s MAC AddressThere are some configuration operations that require you to enter the CM’s MAC address. If the CM’s MAC address is not printed on the CMAP, you can retrieve it via the command line interface.To perform this procedure, you will need the following:■An administrative computer
47TroubleshootingHow Radio Frequency Scanning Works■An Ethernet cable■A Telnet or SSH (secure shell) client programDo the following1. Connect one end of the Ethernet cable to the administrative computer’s Ethernet port, and then connect the other end to the CMAP’s Ethernet port.2. Change the administrative computer’s IP address to the same subnet as the CMAP. The CM’s default IP address is 192.168.100.1.3. Start the Telnet or SSH client program on the administrative computer.4. Log onto to the CM via Telnet or SSH using the following logon details:•User name: super•Password: mso-admin5. When the command prompt appears, enter the following command:cd ncd halmac_address 1The command prompt displays the CM’s MAC address.How Radio Frequency Scanning WorksTo perform radio frequency scanning, the AP does the following:1. Looks at the last “known good channel” (repeat this every 64 channel checks).2. Checks the sixteen last known frequencies (repeat this every 32 channel checks).3. Scans standard channels (where the center of the channel is an integer spaced by 6 MHz), first [from 94.25 MHz to 1001.25 MHz - 152 channels]).4. Scans the harmonically related carriers (HRC) channels, which moves the channels 1.25 MHz off the standard frequencies so the video carriers are all related by 6 MHz [from 93 to 999 MHz - 152 channels].A complete frequency scan requires approximately 469 channel checks. Since each channel takes about 0.6 seconds, a full scan is done every 281 second (a little under 5 minutes).Contacting Ruckus Wireless SupportFor assistance in troubleshooting other issues that are not described in this guide, contact Ruckus Wireless technical support (see below):■Email: support@ruckuswireless.com■Web Site: http://support.ruckuswireless.com/
