Hot Swap Board

The SCSI Hot Swap Board allows the installation, removal or exchange of DE200i-S 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 being done 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

If the Hot Swap Board is not already attached to the DE200 receiving frame, follow the steps

below for installation instructions. Otherwise, proceed to the "Using the Hot Swap Board"

section for usage instructions.

IMPORTANT NOTE: The device carrier should be locked into the receiving frame prior to the

following procedures to maintain proper connector alignment between

the receiving frame and the device carriers.

1.

Remove the two (2) 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 7 & 8, and

J6 - Pins 1 & 2 (Figure 5). Verify that W2 is set to position "A" (default setting) to

disable onboard termination from the receiving frame motherboard.

3.

Attach the two (2) provided stand-offs 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 motherboard 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 stand-

offs.
