HP Switch zl2 Modules Installation Guide

Features
The v2 zl Modules have the following features:
■ All v2 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
• “hot swap SFPs” operation—you can add, replace, or change the type
of any of the SFPs 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 16.)
