Mini-GBIC Type and Hardware/Software Support
Note: If you see an amber blinking mini-GBIC port status LED after you install a
mini-GBIC into the Summit24e3 or Summit48si switch, this means the 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 port in
the switch.
Preparing to Install or Replace a Mini-GBIC
To ensure proper installation, complete the following tasks before inserting the
mini-GBIC:
• Disable the port that is needed to install or replace the mini-GBIC.
• Inspect and clean the fiber tips, coupler, and connectors.
• Prepare and clean an external attenuator, if needed.
• Do not stretch the fiber.
• Make sure the bend radius of the fiber is not less than 2 inches (5.08 cm).
When installing or replacing mini-GBICs on an active network, use the same type of
mini-GBIC at each end of the link.
Once you complete all of these tasks, you are ready to install or replace a mini-GBIC.
Installing and Removing a Mini-GBIC
You can add and remove mini-GBICs from your Summit24e3 switch without powering
off the system. Figure 1-1 shows the mini-GBIC connector.
