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.

NOTE

If you see an amber blinking mini-GBIC port status LED on your Summit24e3 switch, you do not have

an Extreme-supported mini-GBIC installed in your switch. To correct this problem, make sure you install

an Extreme-supported mini-GBIC into the port on the switch.

Remove the LC fiber-optic connector from the mini-GBIC prior to removing the mini-GBIC from the

switch.
