Extreme Networks Consolidated "i" and "e" Series Hardware Installation Guide

This section describes the requirements for the LX100 GBIC. Read the information in this section before 
you install an LX100 GBIC. 

If you have an Alpine 3800 series switch populated with a GM-4Xi module, do one of the following:

Install a maximum of three LX100 GBICs per GM-4Xi module; the fourth GBIC slot must remain 
empty.

Install two or fewer LX100 GBICs per GM-4Xi module, and leave the remaining GBIC slots empty.

Install two or fewer LX100 GBICs per GM-4Xi module, and install any combination of the following 
GBICs into the empty slots:

1000BASE-SX

1000BASE-LX

ZX GBIC

ZX Rev 03

LX70

UTP GBIC

To ensure correct operation of the LX100 GBIC, make sure you run ExtremeWare 6.1.9 or later on your 
switch.

The UTP GBIC operates in full-duplex mode only. The UTP GBIC does not operate in 10/100 Mbps 
mode, and it does not support autonegotiation of link speed. 

You must disable autonegotiation on the ports that use the UTP GBIC and manually configure the port 
speed to 1000 Mbps. 

The following example disables autonegotiation, configures a port speed of 1000 Mbps, and specifies 
full-duplex mode for port 4 on a stand-alone switch:

config ports 4 auto off speed 1000 duplex full

The following example disables autonegotiation, configures a port speed of 1000 Mbps, and specifies 
full-duplex mode for port 1 on a G8Xi module located in slot 1 of a modular switch:

config ports 1:1 auto off speed 1000 duplex full

The UTP GBIC is supported on “i” series products only.
