gl Modules Installation Guide 2003-11

Features

The HP ProCurve Switch gl Modules have the following features:

■ auto-enabled ports—the ports are all configured to be ready for network

operation as soon as a viable network cable is connected.

■ auto-configuration—a default configuration is applied to the module

when the switch is powered on and the module passes self test; this default

configuration works well for most network installations.

■ LEDs that provide information on the link status, network activity,

connection bandwidth, and communication mode (half or full duplex).

■ “hot swap modules” operation—you can add a module or replace a

module without having to shut down the switch (changing the module

type in a given slot does require a switch reset).

■ “hot swap transceivers and mini-GBICs” operation—you can add, replace,

or change the type of any of the transceivers and mini-GBICs that you use

in the Gigabit Transceiver gl Module and mini-GBIC gl Module, without

having to first remove the module, and without having to shut down the

switch.

■ the ports on the 10/100-TX gl Module have the HP Auto-MDIX feature,

and the ports on the 100/1000-T gl Module have the IEEE 802.3ab Auto

MDI/MDI-X feature. These features operate the same way and allow you

to use either straight-through or crossover twisted-pair cables for all the

twisted-pair network connections. Please see the note on “Automatic

Cable Sensing” on

page 11.

■ standards adherence:

• the 10/100-TX gl Module is compatible with the IEEE 802.3

10Base-T and IEEE 802.3u 100Base-TX standards

• the 100/1000-T gl Module is compatible with the IEEE 802.3ab

1000Base-T and IEEE 802.3u 100Base-TX standards

• the ports on the transceivers that are installed in the Gigabit Trans-

ceiver gl Module are compatible with their appropriate standards. See

the Installation Guide the comes with the transceivers.

• the ports on the Gigabit-SX and Gigabit-LX mini-GBICs that are

installed in the mini-GBIC gl Module are compatible with the IEEE

802.3z Gigabit-SX and Gigabit-LX standards respectively.

• the ports on the 100-FX MTRJ gl Module are compatible with the IEEE

802.3u 100-FX standard.
