UTP GBIC
To ensure correct operation of the LX100 GBIC, make sure that 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 need to 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.
Long Range GBIC System Budgets
Measure cable plant losses with a 1550 nm light source and verify this to be within budget. When 
calculating the maximum distance attainable, using optical cable with a specified loss per kilometer (for 
example, 0.25 db/km), Extreme Networks recommends that 3 dB of the total budget be reserved for 
losses induced by cable splices, connectors, and operating margin. Figure 2 shows the total optical 
system budget between long range GBICs.
NOTE
The fiber loss budget plus all other penalties must not exceed the total optical system budget.
