Replacing a Fiber Optic Module
You can remove an SFP or XFP from a port and replace it with a new one while the FGS is powered on and
running.
This section provides information about the following tasks:
• Removing a fiber optic module
• Installing a new fiber optic module
• Cabling a fiber optic module

Removing a Fiber Optic Module

You can remove a fiber SFP (also called a mini-GBIC) or an XFP from a port while the FGS is powered on and
running.
Before removing a fiber optic module, have the following on hand:
• An ESD wrist strap with a plug for connection to the ESD connector on the FGS.
WARNIN G: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor.
• The protective covering that you removed from the fiber optic module when you initially installed the module.
To remove a fiber optic module from a Gigabit Ethernet or 10-Gigabit Ethernet port, do the following:
1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a metal surface (such as an
equipment rack).
2. Disconnect the fiber cable connector from the port connector.
3. Insert the protective covering into the port connectors.
4. Pull the fiber optic module out of the port by pulling the bail latch forward, away from the front panel of the
module. This unlocks the module from the front panel.
NOTE: The bail latch may be attached to either the top or the bottom of the mini-GBIC.
5. Grasping the bail latch, pull the fiber optic module out of the port.
6. Store the fiber optic module in a safe, static-free place or in an anti-static bag.
7. Install a new fiber optic module in the port. For information about performing this task, see “Installing a New
Fiber Optic Module” .
