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. As a wireless air monitor, a uniquely Aruba feature, the Aruba 52 enhances wireless networks by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies, balancing wireless traffic load, self-healing coverage gaps, and more. Product Features Wireless dual-band transceiver Dual, omnidirectional antennas for reception diversity Protocol-independent networking functionality 802.11a – up to 54 Mbps data rate per channel: offers a high data rate and reliable wireless connectivity 802.11b – up to 11 Mbps data rate per channel: provides an alternative to wired LANs that can dramatically cut costs 802.11g – up to 54 Mbps data rate per channel: backwards compatible with 802.11b Compatible with IEEE 802.3af Power Over Ethernet (POE) Seamless connectivity to wired LANs augment existing networks quickly and easily Can be centrally managed, configured, and upgraded through the Aruba WLAN Switch to take advantage of network changes and security improvements Introduction Chapter 1 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 802.11a operation, the Aruba 52 uses a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA). It operates in the 5GHz Unlicensed National Information Infrastructure (UNII) band. Data is transmitted over a half-duplex radio channel operating at up to 54 Megabits per second (Mbps). For IEEE 802.11b operation, the Aruba 52 uses the IEEE 802.11 High-Rate Direct Sequence (HRDS) specification, and a shared collision domain (CSMA/CA). It operates in the 2.4GHz Industrial/Scientific/Medical (ISM) band. The ISM band is available worldwide for unlicensed use. Data is transmitted at speeds of up to 11 Mbps. For IEEE 802.11g operation, the Aruba 52 uses ODFM and a shared collision domain (CSMA/CA). It operates in the 2.4GHz Industrial/Scientific/Medical (ISM) band. The ISM band is available worldwide for unlicensed use. Data is transmitted at speeds of up to 54 Mbps. Power Over Ethernet The Aruba 52 supports the IEEE 802.3af standard for Power Over Ethernet (POE). With this feature, the Aruba 52 can accept electrical power from a compatible POE-capable device to which it is connected, directly over the FE cable. POE eliminates the need to provide separate power outlets in environments that are difficult or undesirable to wire for electricity. The Aruba 52 supports POE only when the FE port is connected to an IEEE 802.3af compliant device (such as the Aruba 5000 WS-5032 Line Card).

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). If you plan to manually generate the location data, record the following information for each access point and air monitor. It will be required when configuring the Aruba WLAN Switch. Building Number A unique number (1-255) is required for each building in your campus. Floor Number Within any building, a unique number (1-255) is required for each floor. Device Number Within any floor, a unique number (1-65536) is required for each access point or air monitor. Device Description Note the intended function of the device (access point or dedicated air monitor) and a brief description of its service location. X, Y Coordinates For each access point and air monitor, measure its X and Y position (in feet) relative to the bottom-left corner of the building plan as seen from overhead. For example: 262 ft. 98 0,0 126 418 ft. Use the same fixed point and orientation for all floors in a building. Setup & Installation Chapter 2 15 7/29/03 FINAL DRAFT—CONFIDENTIAL 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). If DNS is not available, then the IP address of the server hosting the AP software image and the address of the server hosting the configuration file must be specified. This is accomplished using the environment variables serverip and master respectively. CAUTION—The serverip and master environment variables take precedence over the servername variable. Therefore, if you set serverip or naster the AP will use those addresses to search for the software image and the configuration file instead of looking for the server specified in servername. NOTE—The software image and the configuration file are usually stored on the same server. z If you are not using DNS, you must manually configure the Aruba 52 with the IP address of the master Aruba WLAN Switch: apboot> setenv serverip apboot> setenv master z If you are using DNS but wish to specify a different host, use the following command: apboot> setenv servername 16 Aruba 52 Installation Guide Part 0500007B August 2003 7/29/03 FINAL DRAFT—CONFIDENTIAL Table 2-2 summarizes the server environment variables discussed above. TABLE 2-2 Server Enviornment Variable 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.
