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
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 – 11 Mbps data rate per channel: provides an alternative to wired LANs that can
dramatically cut costs
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
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).

LAN or POE Connection
Use this procedure when connecting the Aruba 50 through the LAN or to a non-SPOE network port on theAruba WLAN Switch.
NOTE—If connecting the Aruba 50 directly to a SPOE network port on the Aruba WLAN
Switch, see the instructions on page 18.
Connect the Aruba 50 to the network.
Connect one end of an FE cable to a network hub, router, or switch that has a routable
path to the Aruba WLAN Switch.
If the connecting device supports POE (see “Power Over Ethernet” on page 2), use an
8- or 4-conductor, Category 5 UTP, straight-through FE cable.
If the connecting device does not support POE, use a 4- or 8-conductor, Category 5
UTP, straight-through or crossover FE cable.
Any FE cable installed in an air-handling space, as described in NEC (2002) Article
300.22(C), should be suitable under NEC Article 800.50 and marked 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.
For port and cable details, see Appendix B.
Connect the other end of the FE cable to the FE port on the back of the Aruba 50.
Connect power.
The Aruba 50 can receive electrical power using the following options:
z POE–If connecting the Aruba 50 to a device that supplies IEEE 802.3af compliant POE
(see “Power Over Ethernet” on page 2), no additional power connection is necessary.
z Power Outlet
NOTE—When the Aruba 50 is installed in an air-handling space, as described in NEC
(2002) Article 300.22(C), POE must be used instead of a power outlet.
If local regulations and practices permit, connect the included AC power adapter cable to
the DC power socket on the rear panel of the Aruba 50 and plug it into an appropriate
power outlet.
CAUTION—Use only the AC power adapter supplied with this device. Otherwise, the product may be damaged.
