Installing or Replacing a Mini-Gigabit Interface Connector
(Mini-GBIC)
This section describes the safety precautions and preparation steps that you must perform before
inserting and securing a mini-GBIC.
Safety Information
Before you begin the process of installing or replacing a mini-GBIC, read the safety information in this
section.
CAUTION
Mini-GBICs can emit invisible laser radiation. Avoid direct eye exposure to beam.
Mini-GBICs are a class 1 laser device. Use only Extreme-approved devices.
Remove the LC fiber-optic connector from the mini-GBIC prior to removing the mini-GBIC from 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.
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 side of the link.
Once you complete all of the described tasks, you are ready to install or replace a mini-GBIC.
