7/29/03 FINAL DRAFT—CONFIDENTIAL x Aruba 52 Installation Guide Part 0500007B August 2003
7/29/03 FINAL DRAFT—CONFIDENTIAL CHAPTER 1 Introduction The Aruba 52 is part of a comprehensive wireless network solution. The device works in conjunction with the Aruba 5000 WLAN Switch and can act as a wireless access point or air monitor. As a wireless access point, the Aruba 52 provides transparent, secure, high-speed data communications between wireless network devices (fixed, portable, or mobile computers with IEEE 802.11a, 802.11b, or 802.11g wireless adapters) and the wired LAN.
7/29/03 FINAL DRAFT—CONFIDENTIAL Ethernet Compatibility The Aruba 52 attaches to 10/100 Mbps Ethernet (FE) LAN segments that utilize 10Base-T/100Base-TX (twisted-pair) wiring. The device appears as an Ethernet node and performs a routing function by moving packets between the wired LAN and remote workstations on the wireless infrastructure. Radio Characteristics For IEEE 802.

7/29/03 FINAL DRAFT—CONFIDENTIAL Select a Network Topology The Aruba 52 can be installed in your network using the following topologies: 1 Direct SPOE Installation Aruba 5000 w/SPOE Serial, Power & Ethernet Management Workstation LAN Aruba 50 Data Network Mgmt. Network 2 POE Installation Power & Ethernet Management Workstation LAN Switch w/POE Aruba 5000 LAN Aruba 50 Data Network Serial Console (Initial Setup Only) Mgmt.
7/29/03 FINAL DRAFT—CONFIDENTIAL 1 Direct Serial & Power Over Ethernet (SPOE) to the Aruba WLAN Switch (recommended) In this topology, both the console and 10/100 Mbps Ethernet (FE) ports on the Aruba 52 are connected to the SPOE adapter. An 8-conductor, Category 5 UTP, straight-through FE cable connects the adapter directly to the Aruba WLAN Switch with no intervening hubs, routers, or other network equipment.
7/29/03 FINAL DRAFT—CONFIDENTIAL Perform Initial Setup The Aruba 52 requires some initial configuration before it will operate. The method used for connecting to the Aruba 52 for initial setup depends on your intended network topology (see Figure 2-1 on page 8). Direct SPOE to the Aruba WLAN Switch Use this procedure when connecting the Aruba 52 directly to an SPOE-compatible network port on the Aruba WLAN Switch (see “Power Over Ethernet” on page 2).
7/29/03 FINAL DRAFT—CONFIDENTIAL 3 Telnet to the Aruba WLAN Switch Serial-Over-Ethernet (SOE) interface. Use a Telnet client on your management workstation to connect to theAruba WLAN Switch IP address using logical port 2300.
7/29/03 FINAL DRAFT—CONFIDENTIAL 6 From the Aruba 52 console, access the boot prompt. Depending on the Aruba 52 status, you will see one of the following on your terminal: z Autoboot countdown—The countdown prompt allows you to interrupt the normal startup process and access the boot prompt where initial configuration is performed. APBoot 1.0.6 (May 19 2003 - 14:52:48) CPU: MPC8245 Revision 16.
7/29/03 FINAL DRAFT—CONFIDENTIAL Direct Terminal Connection Use this procedure when connecting the Aruba 52 through the LAN or to a non-SPOE network port on the Aruba WLAN Switch. Under these topologies, a direct terminal connection is required for initial setup. NOTE—If connecting the Aruba 52 directly to a SPOE network port on the Aruba WLAN Switch, see the instructions on page 10. 1 Connect power to the Aruba 52.
7/29/03 FINAL DRAFT—CONFIDENTIAL 2 Set up your local terminal. This procedure requires a terminal or computer running terminal emulation software with the following settings: TABLE 2-1 Console Terminal Settings 3 Baud Rate Data Bits Parity Stop Bits Flow Control 9600 8 None 1 None Connect the terminal directly to the Aruba 52. Use a standard serial cable to connect the Aruba 52 console port to a serial port on your terminal (see Appendix A for port specification).
7/29/03 FINAL DRAFT—CONFIDENTIAL Configure the Aruba 52 From the boot prompt, set the intended location for the Aruba 52: apboot> setenv location .. If you performed the recommended site survey using the Aruba WLAN Switch’s built-in planning tools, the location data for all access points and air monitors can be found on the tool’s deployment screen (see the Aruba AirOS Software Guide).
7/29/03 FINAL DRAFT—CONFIDENTIAL 2 Specify host information, if necessary. The Aruba 52 uses the default host name aruba-master to find the host Aruba WLAN Switch and download its software. This assumes that your DNS has been configured to resolve aruba-master to the master Aruba WLAN Switch IP address. z If DNS is available, the AP will use servername environment variable to find the host and download the AP software image and the configuration file (unless serverip and/or master are set).
7/29/03 FINAL DRAFT—CONFIDENTIAL Table 2-2 summarizes the server environment variables discussed above. TABLE 2-2 Server Enviornment Variable 3 Variable Name Default Value Use Comments servername aruba-master DNS name of the master M-switch. Also serves as the TFTP servername if serverip is not set. serverip n/a IP address of the TFTP server. Overides servername for TFTP image download. Use only if DNS is unavailable or must be bypassed. master n/a IP address of the master M-switch.
7/29/03 FINAL DRAFT—CONFIDENTIAL Mount the Aruba 52 When initial setup is complete, mount the Aruba 52 in its intended service location. Select a location as close as possible to the center of the intended coverage area. If necessary, use the Aruba WLAN Switch’s built-in site survey software to determine the optimum locations for your access points and air monitors (see your Aruba AirOS Software Guide). The service location should be free from obstructions or obvious sources of interference.
7/29/03 FINAL DRAFT—CONFIDENTIAL Free-Standing Placement To place the Aruba 52 on a flat table or shelf, first attach the included non-skid foot-pads to the bottom of the chassis. CAUTION—Do not place the Aruba 52 in any place where it could fall on people or equipment. For more secure installation, use the optional mounting kit. Using the Built-In Mounting Slots The keyhole-shaped slots on the bottom of the Aruba 52 can be used to attach the device to a wall or shelf.
