Installing New Rsp4 Or Rsp8 Dimms - Cisco 7500 Series Configuration Manual

Upgrading or Replacing DRAM DIMMs on the RSP4 and RSP8

Installing New RSP4 or RSP8 DIMMs

This section describes the procedure for installing new RSP4 or RSP8 DIMMs.
Note If you are upgrading from 32 MB to 64 MB or from 128 MB to 256 MB, you need to add one DRAM
DIMM to U13 (RSP4), or U15 (RSP8); therefore, the following procedure is required. Use the following
procedure to install the new DIMMs:
Place the RSP4 or RSP8 on an antistatic mat or pad, and ensure that you are wearing an antistatic device,
Step 1
such as a wrist strap.
Position the RSP4 or RSP8 so that the faceplate is toward you and the edge connector is away from
Step 2
you—this position is shown in

Caution
damage. Handle DIMMs by the edges only; avoid touching the DIMMs, pins, or traces.
Step 3 Remove the new DIMM from the antistatic bag.
Hold the DIMM component-side up, with the connector edge (the metal fingers) closest to you. Hold the
Step 4
ends of the DIMM between your thumb and forefinger.

Tilt the DIMM to approximately the same angle as the socket and insert the connector edge into the
Step 5
socket. Note the two notches (keys) on the connector edge of the DIMM. These keys are intended to
ensure correct orientation of the DIMM in the socket.
Caution When inserting DIMMs, use firm but not excessive pressure. If you damage a socket, you will have to
return the RSP4 or RSP8 to the factory for repair.
Step 6 Note the orientation of the socket key on the DIMM and the DIMM socket and gently push the DIMM
into the socket until the lever is flush against the side of the DIMM socket, and the DIMM edge
connector is fully inserted. If necessary, rock the DIMM gently back and forth to seat it properly.
