Replacing SFPs on GE I/O Modules

This section describes how to replace small form-factor pluggable transceivers
(SFPs) on Gigabit Ethernet (GE) modules that support these devices. A range
of SFPs that support different optical modes (multimode and single mode)
and cabling distances is available. You can replace the SFPs without disabling
the interfaces or removing the module from the system.
WARNING: Do not insert any metal object, such as a screwdriver, or place your
hand into an open slot or the backplane when the E-series router is on. Remove
jewelry (including rings, necklaces, and watches) before working on equipment that
is connected to power lines. These actions prevent electric shock and serious burns.
CAUTION: When handling electronic components, use an antistatic wrist strap
connected to the system's ESD grounding jack, and hold components by their
edges. Do not touch, pins, leads, or solder connections. Store components in
antistatic bags. These actions help to protect modules from damage by electrostatic
discharge.

Removing SFPs

To remove the SFPs:
1.
Repeat Steps 2 through 3 with the other SODIMM.
Repeat Steps 1 through 4 for the other SRP module, if present.
Place the SRP modules in the chassis.
The SRP modules will reboot.
Close the ejector handles and tighten the thumbscrews.
Issue the show hardware command, and verify that the display indicates that
the correct amount of memory is present.
Obtain an antistatic container for the SFPs you will remove (see "Storing
Modules and Components" on page 82).
