CHAPTER 1
Introduction
The Aruba 50 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 50 provides transparent, secure, high-speed data communications between wireless network devices (fixed, portable, or mobile computers with
IEEE 802.11a or IEEE 802.11b wireless adapters) and the wired LAN.
As a wireless air monitor, a uniquely Aruba feature, the Aruba 50 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
z Wireless dual-band transceiver
z Dual, omnidirectional antennas for reception diversity
z Protocol-independent networking functionality
z 802.11a – up to 54 Mbps data rate per channel: offers a high data rate and reliable wireless
connectivity
z 802.11b – 11 Mbps data rate per channel: provides an alternative to wired LANs that can
dramatically cut costs
z Compatible with IEEE 802.3af Power Over Ethernet (POE)
z Seamless connectivity to wired LANs augment existing networks quickly and easily
z Can be centrally managed, configured, and upgraded through the Aruba WLAN Switch
to take advantage of network changes and security improvements
Introduction 1
Chapter 1
4/3/03 Accton Draft—CONFIDENTIAL
Ethernet Compatibility
The Aruba 50 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 50 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), and with a maximum operating range up to 503 m (1650 ft.).
Power Over Ethernet
The Aruba 50 supports the IEEE 802.3af standard for Power Over Ethernet (POE). With this
feature, the Aruba 50 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 50 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).

The FE port detects MDI/MDX and automatically adjusts for straight-through or crossover
cables. However, if Power Over Ethernet (POE) is used, a straight-through cable is required.
The maximum length for FE cables is 100 meters (325 feet).
When the Aruba 50 is installed in an air-handling space, as described in NEC (2002) Article
300.22(C), POE is required. Also, any FE cable installed in such spaces should be suitable
under NEC Article 800.50 and marked accordingly for use in plenums and air-handling spaces
with regard to smoke propagation, such as CL2-P, CL3-P, MPP or CMP.
Install cables in accordance with all applicable local regulations and practices.

SPOE Adapter
The Serial & Power Over Ethernet (SPOE) adapter pin-outs are shown in Figure B-3:
Figure B-3 Aruba SPOE Adapter
The adapter requires an 8-conductor Category 5 UTP, straight-through FE cable with RJ-45
male connectors. The cable must connect the SPOE adapter to an FE+SPOE port on the
Aruba WLAN Switch, with no intervening hubs, routers, or other network equipment.
The maximum length for FE cables is 100 meters (325 feet).
The Aruba 50 and SPOE adapter are plenum rated. When is installed in an air-handling space,
as described in NEC (2002) Article 300.22(C), the connecting FE cable should be suitable
under NEC Article 800.50 and marked accordingly for use in plenums and air-handling spaces
with regard to smoke propagation, such as CL2-P, CL3-P, MPP or CMP.
Install cables in accordance with all applicable local regulations and practices.
