Replacing SFPs on GE I/O Modules

To verify that the upgrade is complete:
1. Place the SRP modules in the chassis.
The SRP modules will reboot.
2. Close the ejector handles and tighten the thumbscrews.
3. Issue the show hardware command, and verify that the display indicates that
the correct amount of memory is present.
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.
Do not insert any metal object, such as a screwdriver, or place your
WARNING:
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.
When handling electronic components, use an antistatic wrist strap
CAUTION:
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.
To remove the SFPs:
1. Obtain an antistatic container for the SFPs you will remove (see
and Components, earlier in this chapter).
2. Put the antistatic wrist strap on your wrist, and connect the strap to the ESD
grounding jack on the system.
3. Disconnect the cables from one of the SFPs on the module.
4. Identify the release mechanism for the SFP.
Different SFPs use different release mechanisms (see Figure 45). Possible
release mechanisms include:
