Cisco Systems OL-7861-01 manual General GBIC Handling and Maintenance Guidelines

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 page 9 .

•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:

Step 1 Disconnect the SC-type fiber-optic cables from the GBIC. Note which plug is TX and which plug is RX for reattachment.

Step 2 Attach an ESD wrist or ankle strap and follow its directions for use.

Step 3 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 Figure 16.)
