Memory Configuration Rules

rp54xx servers have 16 slots (8 DIMM pairs) for memory DIMMs. These slots are numbered 0a/b, 1a/b,... 7a/b.
8 of these slots (4a/b - 7a/b) are disabled on rp5400 servers. rp5450 servers can access all slots. rp5400 and
rp5450 servers have DIMM slots located on the System Board.
rp5470 servers install DIMMs using Memory Carriers. The Memory Carriers fit into slots on the System
Board.
The following rules govern the installation of memory DIMMs for rp5400, rp5450, and rp5470 servers:
• Memory must be installed in DIMM pairs.
• The capacity of DIMMs within a pair must be the same.
• Install DIMMs with the greatest capacity in the lowest slot numbers.
• Install DIMMs the following slot order: 0a/b, 1a/b, 2a/b, 3a/b, and so on.
Installing rp5400 and/or rp5450 DIMMs
Step 1. Power down and unplug the rp54xx server.
CAUTION
Step 2. Loosen the captive T-15 screws that hold the top cover in place, then grasp the strap handle, raise
the cover slightly, and pull the cover toward the front of the server to free the cover tabs from the
slots in the chassis. The air baffle will be exposed.
Step 3. Make the top of the server accessible for service.
Chapter 3
DC voltages are present when the server is connected to AC power. Do not install or
service rp54xx internal components while DC voltage is present. Failure to observe
this precaution can result in damage to the server.
