Figure 1-14. SCSI Backplane Board
CAUTION: Should you remove power from the SCSI backplane board
(either by removing the power cable or during replacement of the
system board battery), you may need to reflash your system’s
firmware.
The original firmware on the SCSI backplane is stored in EEPROM.
However, if the SCSI backplane firmware is ever updated, the update
is stored in volatile RAM. If power is removed from an updated back-
plane board, the update will be lost and the board will revert to its
original firmware in EEPROM.
If at system startup you receive the message Warning: Firmware is
out-of-date, please update..., it is best to reflash all system
firmware from your Dell Server Assistant CD.
