Example: The HP Procurve 24-Port 10/100-TX GL Module
Features: The HP Procurve Switch GL Modules have the following features:
auto-enabled ports—the ports are all configured to be ready for network
I
operation as soon as a viable network cable is connected
I 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,
I
connection bandwidth, and communication mode (half or full duplex)
I "hot swap" 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)
the ports on the 10/100-TX GL Module have the HP Auto-MDIX feature,
I
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 7.
I 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.
