Table 5 describes the specifications for the 1000BASE-SX 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.
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.
