Total Route Memory			Cisco Product Number	DIMM Modules	SDRAM DIMM Sockets1
1	GB2		MEM-PRP2-1G	1 1-GB DIMM	Bank 1	(U15)
2	GB		MEM-PRP2-2G	1x2G DIMM or	Bank 1	(U15) and Bank 2 (U18)
				2x1G DIMMs

1.Bank 1 (U15) must be populated first.

2.One 1-GB DIMM is the default SDRAM configuration for PRP-2.

3.A PRP-2 in the Cisco XR 12000 Series Router does not support 3-GB route memory.

4.The larger DIMM must be placed in Bank 1 (U15).

Note If your system includes redundant PRPs, both PRPs should have the same memory size. Redundancy is not supported when using a GRP and a PRP in the same chassis. Cisco strongly recommends that you avoid configuring your router using mixed route processor cards. Refer to the Route Processor Redundancy Plus for the Cisco 12000 Series Internet Router publication for more information.

Caution Only Cisco-approved memory is supported. Do not attempt to install other devices or non-Cisco approved DIMMs in the DIMM sockets. (See Table 15 and Table 16.)

Removing a DIMM

To remove a DIMM from a line card, follow these steps:

Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 Locate the DIMM sockets on the line card.
