Maintenance Information

Note The total 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.

Table 4 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.

Table 4 RSP8 DRAM DIMM Configurations1

Product Numbers	Quantity	DRAM Sockets	Totals
MEM-RSP8-64M=2	Two 32-MB DIMMs or	U12 and U15	64 MB
	one 64-MB DIMM	or U12
MEM-RSP8-128M=	One 128-MB DIMM	U12	128 MB
MEM-RSP8-256M=	Two 128-MB DIMMs	U12 and U15	256 MB

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.

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 DIMM by 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.)

Note Use only SDRAM DIMMs from Cisco Systems. A Cisco manufacturing part number appears on each

SDRAM DIMM.
