Route Switch Processor (RSP8) Installation and Configuration Guide
OL-4920-02
Maintenance Information
Note Thetotal number of memory devices per DIMM differs for each manufacturer. The DIMMs in Figure 2
are generic representations of the actual DRAM DIMMs for your RSP.
Table4 lists the various configurations of DRAM DIMMs that are available, the number of DIMMs for
each configuration, and the DRAM banks they occupy. Note which banks are used, given the
combinations of available DIMM sizes and the maximum DRAM you require.
Caution To prevent system and memory problems when you install DRAM, the RSP8 DRAM DIMMS must be
3.3V devices. Do not attempt to install higher-voltage devices in the RSP8 DIMM sockets. Handle the
DIMMby the card edges only, and avoid touching the memory module, pins, or traces (the metal fingers
along the connector edge of the DIMM). (See Figure 13.)
Figure13 Handling the DIMM
Note Use only SDRAM DIMMs from Cisco Systems. A Cisco manufacturing part number appears on each
SDRAM DIMM.

1. Do not mix memory sizes. If installing two DIMMs, both DIMMs must be the same size.

2. The RSP8 default DRAM configuration is 64 MB. The RSP8 ships with either two 32-MB DIMMS or one 64-MB
DIMM.
Two 32-MB DIMMs or
one 64-MB DIMM U12 and U15
or U12 64 MB
