Immediately after you enter the microcode reload command and press Return, the system reloads all
microcode. Configuration mode remains enabled; after the reload is complete, press Ctrl-Z to exit
configuration mode and return to the system prompt.
Step 10
To verify that the VIP4 is using the correct microcode, issue the show startup-config or show
controllers cbus command, which indicates the currently loaded and running microcode version for
each interface processor.

This completes the procedure for downloading microcode to Flash memory.
Upgrading VIP4 Memory
This section provides the guidelines and procedures for upgrading CPU memory (also called program
memory).
To upgrade CPU memory on your VIP4, you must replace the SDRAM DIMM located in socket U1. Be
sure that you locate the correct socket, because you should not upgrade the SDRAM DIMM for packet
memory that is located in socket U5. See
64 MB of CPU memory and 64 MB of packet memory.
You can upgrade CPU memory to 256 MB but you should not upgrade the packet memory from the
Note
standard 64 MB.
In the output display of the show diag command (see page 26), the line that begins with Controller
Note
Memory Size shows the amount of memory installed on the VIP4. Make a note of these memory values,
then compare them after you upgrade memory to verify the upgrade.
The following Cisco Systems memory spare and upgrade kits are compatible with the VIP4:

Depending on your system configuration, a memory upgrade might be required. Also, if a system
problem is determined to be caused by a DIMM, a DIMM replacement might be required.
