SCSI Hot-docking Backplane
The hot-docking backplane provides the following:
•
Five SCA connectors for SCA-compatible SCSI drives
•
Power control for each drive, including automatic slot-power-down
upon removing a drive
•
Signal for a fault indicator on the front panel for each drive
•
Internal I
2
C bus
•
+12 V connector for a fan with tachometer
•
Local I
2
C-based temperature sensor
The SCSI hot-docking backplane provides control signals and power for five
wide/fast 3.5-inch SCA SCSI hard disk drives. The backplane receives
control signals from the Symbios SCSI controller on the system board
through a cable connected to the wide SCSI connector on the backplane.
The backplane gets power from the power system through cables connected
to the two power connectors.
The drives get their control signals and power from the SCA connectors on
the backplane.
The fault indicators on the front panel indicate failure status for each drive
in the bay. These indicators get their signals through a cable connected to
the front panel connector on the backplane.
The temperature sensor on the backplane provides temperature information
to other devices in the system through enclosure service messages.
The backplane power control provides powering down of a drive when a
failure is detected and reported to the SCSI bus. When a new drive is
inserted, the power control waits a short time for the drive to become fully
seated and then applies power to the drive.
Configuration Options
The hot-docking backplane contains only one configuration jumper: J8, the
internal/external jumper.
A jumper is a small plastic-encased conductor—shorting plug—that slips
over two jumper pins.
