The zl Modules have the following features:
■
All zl modules share 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 for each port on the link status,
network activity, connection bandwidth (speed), 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 mini-GBICs" operation—you can add, replace, or change
the type of any of the mini-GBICs that you use without having to first
remove the module, and without having to shut down the switch
•
the RJ-45 ports on all modules have the HP Auto-MDIX and 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. (See the note
on "Automatic Cable Sensing" on
page
26.)
