HP Integrity rx2660 Server User Service Guide

1. Save your system configuration and iLO 2 MP configuration settings.
IMPORTANT: Before removing the system board, record all boot configuration settings (find
the settings using the INFO ALL EFI command). You must reset these values after replacing
the battery. Use the LS EFI command to gather the LAN configuration information.
You can also use the non-volatile RAM configuration backup (NVRAM) backup utility to back
up and store these values. The utility is located on the HP website at http://www.hp.com/go/
bizsupport.com.
For iLO 2 MP configuration settings, see the HP Integrity iLO 2 Operations Guide.

sockets are clearly marked with the correct channel.
NOTE: The cables connect directly to the system board for a non-RAID configuration, and
