Removing and Installing GBICs
Caution To prevent system problems, do not use GBICs from third-party vendors. Use only the GBIC that
shipped with your Gigabit Ethernet line card. These GBICs might contain an internal EPROM that
identifies them to the Cisco IOS software.
Caution To prevent problems associated with data transmission, you must attach this device only to
IEEE 802.3x-compliant devices.
Note The Ethernet line card supports online insertion and removal (OIR) of GBICs. This means that you can
remove and replace GBICs while the system remains powered up. When you remove a GBIC, the
interface becomes inactive because a GBIC is not detected in the GBIC receptacle.
General GBIC Handling and Maintenance Guidelines
Follow these GBIC handling and maintenance guidelines:
•GBICs are static sensitive. To prevent ESD damage, follow the guidelines described in the
“Preventing Electrostatic Discharge” section on page9.
•GBICs are dust sensitive. When the GBIC is stored or when a fiber-optic cable is not plugged into
one of the optical ports on the GBIC, always insert an optical port dust plug.
•Keep the optical port clean. The most common source of contamination in the optical ports is debris
that collects on the ferrules of the optical cable connectors. Use an alcohol swab or Kim-Wipe to
clean the ferrules of the cable connector before inserting it into the GBIC.
Removing the GBIC from an Ethernet Line Card
To remove the GBIC from an Ethernet line card, follow these steps:
Step1 Disconnect the SC-type fiber-optic cables from the GBIC. Note which plug is TX and which plug is RX
for reattachment.
Step2 Attach an ESD wrist or ankle strap and follow its directions for use.
Step3 Locate the tabs on either side of the exposed portion of the GBIC and squeeze them with your thumb and
forefinger, as you gently pull the GBIC out of the GBIC slot. (See arrows in Figure16.)
