Introduction 1Chapter 14/3/03 Accton Draft—CONFIDENTIALCHAPTER 1IntroductionThe Aruba 50 is part of a comprehensive wireless network solution. The device works in con-junction with the Aruba 5000 WLAN Switch and can act as a wireless access point or air mon-itor.As a wireless access point, the Aruba 50 provides transparent, secure, high-speed data com-munications 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 FeatureszWireless dual-band transceiverzDual, omnidirectional antennas for reception diversityzProtocol-independent networking functionalityz802.11a – up to 54 Mbps data rate per channel: offers a high data rate and reliable wireless connectivityz802.11b – 11 Mbps data rate per channel: provides an alternative to wired LANs that can dramatically cut costszCompatible with IEEE 802.3af Power Over Ethernet (POE)zSeamless connectivity to wired LANs augment existing networks quickly and easilyzCan be centrally managed, configured, and upgraded through the Aruba WLAN Switch to take advantage of network changes and security improvementsIEEE802.11b wireless adapters) and the wired LAN. 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 easilyCan be centrally managed, configured, and upgraded through the Aruba WLAN Switchto take advantage of network changes and security improvementstransceiver
4/3/03 Accton Draft—CONFIDENTIAL2Aruba50 Part 0500007AInstallation Guide May 2003Ethernet CompatibilityThe 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 worksta-tions on the wireless infrastructure.Radio CharacteristicsFor 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 EthernetThe 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 compli-ant device (such as the Aruba 5000 WS-5032 Line Card).

Introduction 5Chapter 14/3/03 Accton Draft—CONFIDENTIALRear PanelFIGURE 1-2 Aruba 50 Rear PanelKensington Security SlotThis slot is compatible with a Kensington MicroSaver Security Cable (not included) which can be used to prevent the unauthorized removal of the Aruba 50 from its installed location. To secure the Aruba 50, wrap a security cable around an immovable object, insert the cable’s lock into the Kensington Security Slot, and turn the key.Console PortThis port has a 9-pin, female serial connector. It is used primarily to connect a terminal during initial setup of the Aruba 50. See Appendix B for port details.Using the included SPOE adapter, this port can also be connected directly to an FE port on an Aruba WLAN Switch that supports SPOE (see “Power Over Ethernet” on page 2). This direct connection provides extra maintenance options during normal operation.FE PortThis port attaches the Aruba 50 to 10Base-T/100Base-TX (twisted-pair) Ethernet LAN seg-ments. The port automatically adjusts MDI/MDX to accept either straight-through or cross-over cables. See Appendix B for port details.This port also supports POE (see “Power Over Ethernet” on page 2). When POE is used, a straight-through cable is required.DC Power SocketThis socket is used to connect the included AC power adapter. If POE is being used to supply power to the Aruba 50, the power adapter is not necessary.Mounting Slots (on bottom)The keyhole-shaped slots on the bottom of the chassis are used to mount the Aruba 50.®12345

Setup & Installation 9Chapter 24/3/03 Accton Draft—CONFIDENTIALDirect Serial & Power Over Ethernet (SPOE) to the Aruba WLAN Switch (recom-mended)In this topology, both the console and 10/100 Mbps Ethernet (FE) ports on the Aruba 50 are connected to the included 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. The network port on the Aruba WLAN Switch must include optional SPOE capability (see “Power Over Ethernet” on page 2).This topology provides the following features:z10/100 Mbps Ethernet connectivityzElectrical power through the FE cablezSerial console connectivity through the FE cablezConvenient initial setup through the Aruba WLAN Switch management interface either before or after physical installation of the Aruba 50zExtra console maintenance options during normal operationPOE connection through the LANIn this topology, the Aruba 50 is connected to the LAN through a hub or switch that is POE compatible (see “Power Over Ethernet” on page 2). An 8- or 4-conductor, Category 5 UTP, straight-through FE cable is required. Initial setup requires a local serial console.This topology provides the following features:z10/100 Mbps Ethernet connectivity (depending on the connecting port)zElectrical power through the FE cablezVersatile placement of the Aruba WLAN Switch and Aruba 50s within the networkConnection to a non-POE network port on the Aruba WLAN Switch or other net-work deviceIn this topology, the Aruba 50 is connected to the Aruba WLAN Switch either directly or through the LAN. An 8- or 4-conductor, Category 5 UTP, straight-through or crossover FE cable may be used. Initial setup requires a local serial console. Electrical power is supplied using the included AC power adapter.This topology provides the following features:z10/100 Mbps Ethernet connectivity (depending on the connecting port)zVersatile placement of the Aruba WLAN Switch and Aruba 50s within the network123
4/3/03 Accton Draft—CONFIDENTIAL10 Aruba 50 Part 0500007AInstallation Guide May 2003Perform Initial SetupThe Aruba 50 requires some initial configuration before it will operate. The method used for connecting to the Aruba 50 for initial setup depends on your intended network topology (see Figure 2-1 on page 8).Direct SPOE to the Aruba WLAN SwitchUse this procedure when connecting the Aruba 50 directly to an SPOE-compatible network port on the Aruba WLAN Switch (see “Power Over Ethernet” on page 2). SPOE provides 10/100 Mbps Ethernet, serial connection, and power over one cable.NOTE—If connecting the Aruba 50 through the LAN or to a non-SPOE network port on the Aruba WLAN Switch, see the instructions on page 11.Connect the included SPOE adapter to the Aruba 50.Connect the adapter’s 9-pin serial connector to the Console port on the back of the Aruba 50.Connect the adapter’s male RJ-45 plug to the FE port on the back of the Aruba 50.Connect the Aruba 50 to the Aruba WLAN Switch.The connection between the Aruba 50 and the Aruba WLAN Switch requires an 8-conduc-tor, Category 5 UTP, straight-through FE cable with RJ-45 connectors (see Appendix B for port specifications).Connect one end of the FE cable directly to the RJ-45 socket on the SPOE adapter that was attached to the Aruba 50 in the previous step.Connect the other end of the FE cable directly to an available SPOE network port on the Aruba WLAN Switch.NOTE—The Aruba 50 must be connected to the Aruba WLAN Switch without any inter-vening hubs, routers, or other networking equipment.Telnet to the Aruba WLAN Switch Serial-Over-Ethernet (SOE) interface.Run the Telnet client on your management workstation and connect to theAruba WLAN Switch management IP address using logical port 2300. The connection command may vary depending on the specific software used, but commonly appears as follows:telnet <switch management IP address> 23001AB2AB3
