1About This Installation Guide
This Installation Guide provides information on how to set up the Cable Modem Access
Point (CMAP) on your network. Topics covered in this guide include installation, basic
configuration, operation, and device mounting.
This guide is intended for use by those responsible for installing and setting up network
equipment. Consequently, it assumes a basic working knowledge of local area networking,
cable modem setup and configuration, wireless networking, and wireless devices.
NOTE: The cable modem and access point each have its own independent firmware load
that are updated independently.
Related Documentation
In addition to this guide, each Cable Modem Access Point documentation set includes
the following:
■User Guide: Provides detailed information on how to configure the functions of the
unit. The User Guide is available for download on the Ruckus Wireless Support Web
site at:
http://support.ruckuswireless.com/documents
■Release Notes: Provides late-breaking information about the current software release,
including new features, enhancements, and known issues. If the information in the
Release Notes differs from the information in this guide, follow the instructions in the
Release Notes.
■Online Help: Accessible from the CMAP’s Web interface, the Online Help provides
information that helps you configure the device from the Web interface.
Using ZoneDirector to Manage the CMAP
If you are planning to use a Ruckus Wireless ZoneDirector to manage the CMAP, this guide
describes the required steps that will enable the access point to report to and
communicate with ZoneDirector successfully. Refer to “Configure Option 43 on the DHCP
Server (ZoneDirector Management Only)” on page 16.
Terms Used in This Guide
Before continuing, Ruckus Wireless recommends that you become familiar with the
following terms:
■Access Point (AP): The Wi-Fi component of the Cable Modem Access Point (CMAP).

Unpacking the CMAP
Package Contents
■Cable Modem (or CM): The cable modem component of the Cable Modem Access
Point (CMAP).
■Cable Modem Access Point (or ZF7761CM): The whole unit, which includes the CM
and AP, as well as the power supply.
2Unpacking the CMAP
1. Open the CMAP package, and then carefully remove the contents.
2. Return all packing materials to the shipping box, and put the box away in a dry location.
3. Verify that all items listed in Package Contents below are included in the package.
Check each item for damage. If any item is damaged or missing, notify your authorized
Ruckus Wireless sales representative.
Package Contents
A complete ZoneFlex 7761CM package contains all of the items listed below:
■ZoneFlex 7761CM unit
■Three N-type 5GHz external antennas
■Service Level Agreement / Limited Warranty Statement
■Regulatory Statement
■This Installation Guide
NOTE: The CMAP comes preinstalled with the cable strand interface, which you will use
to mount the assembly onto the cable strand. You only need to attach the three external
antennas to the cable strand interface (after mounting the CMAP on the strand) to
complete the assembly. See “Installing the Antennas” on page 45 for more information.

3Preparing for Installation
This section describes the tasks that you need to perform before proceeding with the
installation. The required tasks depend on whether you are deploying the access point as
a standalone device or as a ZoneDirector-managed device.
■Preconfiguring the Access Point (Standalone Only)
■Configure Option 43 on the DHCP Server (ZoneDirector Management Only)
NOTE: A standalone access point refers to a device that is not managed by Ruckus
Wireless ZoneDirector or Ruckus Wireless FlexMaster.
Preconfiguring the Access Point (Standalone Only)
If you are deploying the access point as a standalone device, Ruckus Wireless strongly
recommends that you preconfigure (or “stage”) the unit before mounting it. It is more
convenient to connect the administrative computer to the access point and configure the
device in the lab than when the device is already mounted on the cable strand.
Preconfiguring the access point requires the following tasks to be completed:
■Step 1: Prepare the Administrative Computer
■Step 2: Supply Power to the CMAP
■Step 3: Log Into the Access Point’s Web Interface
■Step 4: Configure the Wireless Settings
■Step 5: Disconnect the CMAP from the Administrative Computer
■Step 6: Restore the Administrative Computer’s Network Settings
Before starting, prepare the following requirements:
■DC power supply (see DC Power Supply in “Connectors” on page 31)
■One Ethernet cable
■An administrative computer (any computer running Windows that you will use to
preconfigure the access point)

(TCP/IPv4), and then double-click the item. The Internet Protocol Version 4 (TCP/IPv4)
Properties dialog box appears.
7. Write down all of the currently active network settings. You will need this information
later when you restore your computer to its current network configuration.
8. On the General tab, Click Use the following IP address, and then configure the IP
address settings with the values listed in Table 2 . For a sample configuration, refer to
Figure 3.
9. Click OK to save your changes and close the Internet Protocol Version 4 (TCP/IPv4)
