Altos 1100E Series User’s Guide1-28
Features
The backplane board has the following major features:
• “Hot-swap” feature that allows replacement of hard drives even when the
system is in full operation.
• Indicates hard disk drive failure through a front panel LED.
• Supports Ultra2 SCSI SCA disk drives.
• SCSI ID strapping that allows LVD SCSI HDD ID configuration through the
backplane switches, instead of configuring the individual drive IDs.
We recommend setting the IDs on the
backplane board instead of the individual
drives. Refer to the following section for the
location of the SCSI connector ID switches.
If you set the IDs on the backplane board, be
sure to remove all jumper connectors on the
SCSI drive before installing it in the system.
