Removing and Installing GBICs
Your Ethernet line card may have shipped with a GBIC installed. If your line card arrived without the
GBIC installed and you need to install it now, or if you need to change your GBIC for another reason,
use the procedures in these sections:
• General GBIC Handling and Maintenance Guidelines, page 23
• Removing the GBIC from an Ethernet Line Card, page 23
• Inserting a GBIC into the Gigabit Ethernet Interface, page 24
Before you remove or install a GBIC, read the installation information in this section and the “Laser
Safety” section on page 81.
Note Cisco strongly recommends that you disconnect all fiber-optic cables before removing or installing a
GBIC.
