If you have a network processing engine with more than one DIMM socket and are replacing the
Step 6
second DIMM also, repeat steps
This completes the DIMM replacement procedure. Reinstall the VIP4 in the system. (Follow the steps
in the
Upgrade," as required.
Checking the VIP4 Memory Upgrade
After you upgrade the VIP4 memory, verify the memory upgrade:
•
•
If, after you have replaced memory devices, the system fails to boot properly, if the console terminal
displays a checksum or memory error, or if the show diag command output indicates an incorrect amount
of memory (or no memory), check the following:
•
•
•
If after several attempts the system fails to restart properly, contact a service representative for
assistance. Before you call, make note of any error messages, unusual LED states, or any other
indications that might help solve the problem.
This completes the VIP4 memory upgrade.
Installing or Replacing a Port Adapter on a VIP4
Depending on the circumstances, you might need to install a new single-width or dual-width port adapter
on a VIP4 motherboard or replace a failed port adapter in the field. In either case, you need a number 1
Phillips screwdriver, an antistatic mat onto which you can place the removed VIP4, and an antistatic
container into which you can place a failed port adapter for shipment back to the factory. Always handle
the port adapter by the carrier edges and handle; never touch the port adapter components or connector
pins. (See
OL-3673-01
"Installing a VIP4" section on page
Observe the LED states and the console display. When the system has reinitialized all interfaces, the
enabled LEDs on the VIP4 port adapters should go on. (Port adapter status LEDs might be on,
depending on your connections.) The console screen also displays a message as the system discovers
each interface during its reinitialization.
Use the show diag command to verify that the system recognizes the new memory; check the line
of the show diag command output that begins with Controller Memory Size.
Ensure that all memory devices are installed correctly. If necessary, shut down the system and
remove the VIP4. Check the memory devices by looking straight down on them and then at eye level.
The devices should be aligned at the same angle and the same height when properly installed. If a
memory device appears to stick out or rest in the socket at a different angle from the others, remove
the device and reinsert it; then replace the VIP4 and reboot the system for another installation check.
Each DIMM socket must contain a DIMM of the correct size and speed or the system cannot operate.
To ensure this, use only memory devices that are included with Cisco Systems memory kits.
