Hot Swap Feature
The DE100 SCSI Hot Swap Board allows the installation, removal or exchange of Data
Express carriers while your computer system is operating by monitoring and protecting the
computer system and other peripheral devices on the SCSI Bus. The Hot Swap option
eliminates the need to shut down your system when adding or removing a SCSI device by
performing two functions:
1. Delays power up/down of the drive until the time period between SCSI bus cycles.
This prevents the interruption of any SCSI bus activity by other devices on the bus.
2. Prevents drive power sequencing from generating noise on the SCSI bus, thus
preventing data transfer corruption on other devices.
Please note that, whereas UNIX and Apple based systems provide mount/dismount drive
commands, most PC systems do not provide such a feature. When using one of these
operating systems, it may be necessary to reboot the computer after adding or changing a
drive. This reboot activity will force the SCSI host adapter to rescan its SCSI bus for
physically attached drives, and will then be able to access the new or changed drive.
Attaching the Hot Swap Board to the DE100i-SWD
The DE100i-SWD may be purchased with the Hot Swap option factory-installed. If the Hot
Swap Board has not already been attached to the Data Express receiving frame, follow the
instructions below to add the Hot Swap Board:
NOTE: The drive carrier must be installed in the receiving frame when removing or
attaching the Hot Swap Board to ensure proper alignment between the
motherboard and the disk drive.
1. Remove the two Phillips head machine screws from the receiving frame motherboard
and set the screws aside (Figure B-1).
2. Remove jumpers on the receiving frame motherboard locations J4 pins 5-6 and 7-8,
and also on J6 pins 1-2 (Figure 5).
3. Attach the two provided standoffs into the receiving frame motherboard holes in place
of the two removed screws. Carefully align the connectors of the Hot Swap Board
with the connectors on the receiving frame board and gently push the Hot Swap
Board into position. Make certain that all connectors are properly mated.
4. Attach the Hot Swap Board to the receiving frame motherboard by using the two
screws removed earlier and insert them through the Hot Swap Board into the
standoffs.
