Further technical details of the SCSI backplane can be obtained from the SC5100/SC5200 Low
Voltage Differential (LVD)/Single Ended (SE) SCSI Backplane External Product Specification
(EPS).
An optional hot-swap drive bay assembly (AXX2HSDRVUG) is available for the SC5200 chassis.
It should be mounted in place of the middle three 5.25-inch drive trays of the base, non-redundant
chassis models. For the redundant power models, the upgrade accessory should be installed in
the lower three 5.25-inch drive trays to bring the total number of available hot-swap SCSI drives to
ten.
Refer to the Intel
instructions.
5.4
The multi-mode terminators provide SCSI-4 compliant termination for the backplane. These
terminators provide termination in both SE modes and LVD mode. Installing a single SE drive
forces all installed drives to run in the SE termination mode on the SCSI bus.
5.5
The SCSI interface on the SC5100
bus and the microcontroller (containing the intelligence for the SC5100
This interface allows the microcontroller to respond as a SCSI target to implement the SAF-TE
protocol.
Power control on the SC5100
5.6
The Field Effect Transistor (FET) short protection circuit is useful to protect both 12-volt and 5-volt
power control FETs located on LVD/SE SCSI backplane.
1 The SCSI backplane board set used for the SC5200 chassis is the same as previously used in the SC5100
chassis. This board set is referred to as the SC5100 backplane board set below.

SCSI Multi-Mode Termination
SCSI Interface
Spin-down of a drive when failure is detected and reported (using enclosure services
messages) via the SCSI bus. An application or RAID controller detects a drive-related
problem that indicates a data risk. In response, it removes the drive from service and
sends a spin-down SCSI command to the drive. This decreases the likelihood that the
drive will be damaged during removal from the hot-swap drive bay. When a new drive is
inserted, the power control waits a small amount of time for the drive to be fully seated, and
then applies power with a controlled power ramp.
If the system power is on, the LVD/SE SCSI backplane immediately powers off a drive slot
when it detects that a drive has been removed. This prevents possible damage to the drive
when it is partially removed and re-inserted while full power is available, and disruption of
the entire SCSI array from possible sags in supply voltage and resultant current spikes.
