Features
A fault light on the front panel board gives a general
indication that there has been a fault on a hot-swap
drive. Each drive has a set of three lights to indicate
the fault or other status: power-on (green LED),
activity (green LED), or fault (yellow LED).
SCSI Drive Hot-swap Backplane
The SCSI backplane is an integral part of the chassis.
Each backplane provides control signals for six SCSI
peripheral devices. The backplane receives control
signals from the PCI RAID ultra wide SCSI-3 controller
channel.
The backplane has two main functions: SCSI drive
control and system data logging. Drive status is
monitored to detect failing drives and to control LED
indicators. The backplane features are:
■
Inserting and removing of hard drives while power
is on (referred to as “hot swap”)
■
Simplified cable management
■
SCA connectors to simplify inserting and removing
hard drives
■
SCSI management of fault LEDs.
Each backplane supports SCSI drives with SCA
connectors.
