Preparing To Install Or Replace A Gbic; Safety Information - Extreme Networks Summit 300-24 Hardware Installation Manual

Installing GBICs and Mini-GBICs
• 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.
Requirements for the UTP GBIC
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.

Safety Information

Before you install or replace a GBIC, read the safety information in this section.
CAUTION
GBICs can emit invisible laser radiation. Avoid direct eye exposure to the beam.
GBICs are class 1 laser devices, and they operate at 5 V. Use only Extreme-approved devices.
Disconnect the fiber-optic or UTP cable from the GBIC before removing the GBIC from the I/O module
or the switch.
