If you see an amber blinking mini-GBIC port status LED after you install a mini-GBIC, that mini-GBIC
is not certified by Extreme Networks. To correct this problem, install an Extreme Networks-certified
mini-GBIC, available from Extreme Networks, into the mini-GBIC port.
If you install a mini-GBIC not certified by Extreme Networks into a switch and insert a cable to bring
up the link, the port status LED remains “off” and an error specifying the use of a non-Extreme
Networks-certified mini-GBIC is sent to the syslog. To view the syslog and to determine why the link is
down, use the
show log
command. To correct this problem, install an Extreme Networks-certified mini-
GBIC, available from Extreme Networks, into the mini-GBIC slot.
Preparing to Install or Replace a Mini-GBIC
To ensure proper installation, complete the following five tasks before inserting the mini-GBIC:
1 Disable the port that is needed to install or replace the mini-GBIC.
2 Inspect and clean the fiber tips, coupler, and connectors.
3 Prepare and clean an external attenuator, if needed.
4 Do not stretch the fiber.
5 Make sure the bend radius of the fiber is not less than 2 inches (5.08 cm).
In addition to the previously described tasks, Extreme Networks recommends the following when
installing or replacing mini-GBICs on an active network:
●
Use the same type of mini-GBIC at each end of the link.
●
Connect one end of the link to the Tx port. Without an attenuator, measure the total loss from the Tx
port to the other site of the link. The total loss must not exceed the total optical system budget.
After you complete these described tasks, you are ready to install or replace a mini-GBIC.
