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
.)
