2.Insert a SODIMM from the upgrade kit at an angle of approximately 45 degrees into an empty ceramic connector, so that the notch in the long gold edge of the SODIMM aligns with the notch in the connector.

The notch on the long gold edge is no longer visible when the SODIMM is pressed in far enough.

3.Press the top surface downward into the socket until the socket spring snaps into place and holds it.

4.Repeat Steps 2–3 with the other SODIMM.

5.Repeat Steps 1–4 for the other SRP module, if present.

Verifying the Upgrade

To verify that the upgrade is complete:

1.Place the SRP modules in the chassis. The SRP modules 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.

Replacing SFPs on I/O Modules

This section describes how to replace small form-factor pluggable transceivers (SFPs) on 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 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
