Product Description
The AT-9006 Series Gigabit Ethernet Switches allow you to build a
flexible network topology suited to the demands of your network
environment. The switches provide non-blocking architecture and full-
wire speed performance on all ports. They can serve as high speed
workgroup switches with dedicated links to workstations, printers, and
servers,or as links to additional hubs and switches to forma highspeed
infrastructure for large networks.The switches offer a wide range of
features, including IEEE 803.3u Auto-Negotiation, spanning tree
protocol, and IEEE 802.1p Quality of Service. The switches are also IEEE
802.1Q compliant and supportboth port-based and tagged VLANs.

Mbps and, when operating at 100 Mbps, in either half- or full-duplex
mode. Youcan either setthe speed and duplex mode manually oryou
can allow the switch todo it automatically through auto-negotiation.
Each port has a maximum operating distance of 100 m (328 ft.). The
switch requires Category5 or Enhanced Category5 twisted pair cabling.
Each port is IEEE 802.3ab compatible and can operate as either MDI or
MDI-X. The ports are configured automatically when connected to an
end node. No crossover cables are required.

Six Fiber Optic
1000 Mbps Ports
(AT-9006SX/SC
and
AT-9006LX/SC)
The AT-9006SX/SCand AT-9006LX/SC Gigabit EthernetSwitches feature
six fiber optic ports with dual SC connectors. The ports operate at 1000
Mbps in full-duplex mode. (The ports can be configured as half-duplex,
but since all 1000 Mbps network devices operate at full-duplex, there
should be no reason to set one of the ports to half-duplex.)
Each port on theAT-9006SX/SC Switch has a maximum operating
distanceof550metersusingmultimodefiberopticcabling.Theportson
the AT-9006LX/SC offer a maximum operating distance of 550 m using
multimode cabling or 2 km using single-mode fiber optic cabling.
RS232 Connector The RS232, DB-9 female connector provides out-of-band local
management for the switch. You can use eithera VT100terminal or a
personalcomputerwithaterminalemulationprogramtoconnecttothe
RS232 port. The connector uses astraight-through cable.
System and Port
LEDs The switch features a series of system and portLEDs that you can useto
monitorand troubleshootthe switch.Table2 describes thesystem LEDs.
Table2 System LEDs
LED State Description
Fault OFF Normal operation.
Solid Red The switch or management software is malfunctioning.
Flashing Red The switch is booting, running diagnostic tests, writing
messages to FLASH, or transferring files using XMODEM.
RPS Solid Green An RPS is connected tothe switch. Toverify that theRPS is
operating correctly, refer to your RPS manual. (AT-9006SX/
SC and AT-9006LX/SC only.)

reset the switch statistics storedby the AT-S26 management software.
You can also resetthe switch using the Omegamanagement interface,
as explained in theAT-S26 Management Software User’sGuide.
AC Power
Connector The switch has a single ACpower supply socket on theback panel,
which has autoswitch AC inputs. Refer to Appendix A, Technical
Specifications, for the input voltage range. The power cord acts as an
ON/OFF switch.
