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.
