2.5.3 Backplane board
The backplane board includes the four hot-swappable connectors for the
SCSI drives accessible from the front panel, and several other connectors
that link to the motherboard and main power supply unit.
The backplane board comes pre-installed in the chassis. Normally, you do
not need to remove the backplane from the chassis unless it is damaged
and needs repair. In case you will have to remove and re-install the backplane,
take note of the location of the screws (indicated by circles in the figure
below) that secure it to the chassis.
When installed, the SCSI bridge board appears as shown below.
