Pointing the CMAP to ZoneDirector
If you are deploying the access point to be managed by ZoneDirector, you must ensure
that the CMAP can report to its parent ZoneDirector device on the network. 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)
15
Preparing for Installation
Pointing the CMAP to ZoneDirector
Use SSH to Set the ZoneDirector IP Address on the CMAP
You 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 program
To set the ZoneDirector IP Address on the CMAP via SSH
1. 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-admin
5. 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 info
The 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.
16
Preparing for Installation
Pointing the CMAP to ZoneDirector
Configure 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.
17

Pointing the CMAP to ZoneDirector
Figure 9. In the ASCII area, type the IP address of the ZoneDirector device
The 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.

Before You Begin
Supported Power Sources
Supported Power Sources
The 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.
Heaters
The 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 Begin
Before installing and setting up the CMAP, Ruckus Wireless recommends that you first
complete the following pre-installation tasks.
Prepare the Required Hardware and Tools
You 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.
34
Before You Begin
Perform a Site Survey
Perform a Site Survey
Before 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.
35
Powering the CMAP
Using DC Power (Staging or Debugging Only)
6Powering the CMAP
The 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 power
1. 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 POC
1. 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.
36
Verifying Access Point Operation
Using Power Over Cable (Actual Deployment)
7Verifying Access Point Operation
After 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 AP
1. 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 Mode

Mounting the CMAP
Using SNMP to Reset the Access Point
11 Mounting the CMAP
To 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 CMAP
1. 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.

Installing the Antennas
Using SNMP to Reset the Access Point
12 Installing the Antennas
After 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 that
you 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 antennas
1. 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.

Retrieving the CM’s MAC Address
There 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

How Radio Frequency Scanning Works
■An Ethernet cable
■A Telnet or SSH (secure shell) client program
Do the following
1. 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-admin
5. When the command prompt appears, enter the following command:
cd n
cd hal
mac_address 1
The command prompt displays the CM’s MAC address.
How Radio Frequency Scanning Works
To 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).
