Removing a Memory Board

To remove a memory board:
1. If the server is not configured for hot-plug mirrored memory, you must power down the
NAS e7000 v2 Maintenance and Service Guide
Install only one board. The board must be installed in memory board slot 1.
Bank B of memory board 1 is the mirrored bank.
DIMMs in the mirrored bank must be configured identically to the bank they are
mirroring. Both banks must be populated with DIMMs of the same capacity.
If memory board slot 1 Bank B is not populated, the system automatically switches to
When configured for single-board mirrored memory, the system has no hot-plug capabilities.
Two memory boards must be installed.
Both memory boards must be configured identically. Corresponding banks (for instance,
bank A on the memory board in slot 1 and bank A on the memory board in slot 2) must be
populated with DIMMs of the same size and type.
Do not remove the memory board unless the Ready to Hot Plug LED is green.
If you replace a DIMM, the DIMM must be a PC1600 DDR SDRAM DIMM of the same
capacity as the DIMM you are replacing.
Caution: Electrostatic discharge can damage electronic components. Be sure you are
properly grounded before beginning any installation procedure.
server. Refer to "Powering Down the Server" in this chapter.
Hot-plug replacement procedure: If the server is configured for hot-plug mirrored
memory, skip to step 2.
