Implementing Additional Configuration and Maintenance Tasks

Change it to a value of 0x2102 (factory default) using the config-register0x value command.

Step 13 Enter Ctrl-Zto exit configuration mode.

Step 14 Reboot the router and enable it using the recovered password.

Upgrading GRP Memory

This section provides the procedure for increasing the amount of extended data output (EDO) DRAM on a GRP by replacing up to two dual in-line memory modules (DIMMs). The system DRAM resides on up to two DIMMs on the GRP. The DRAM DIMM sockets are U39 (bank 1) and U42 (bank 2). (See Figure 15 and Table 14.)

The default DRAM configuration is 128 MB (one 128-MB DIMM in U39).

Note The total number of memory devices per DIMM differs for each manufacturer. The DIMMs in Figure 16 and Figure 17 show a generic representation of the actual DRAM DIMMs for your GRP. To be assured that you are using the correct DIMMs, refer to the specific part numbers for your DRAM upgrade kit (see the “DRAM” section on page 6) and to the Cisco part numbers on the DIMMs. (See Table 14.)
