• Remove the top of the chassis from the original system. This will require the removal of the

screws holding it on, which will be located on the front, back, top, and/or sides of the chas-

sis.

• Lift the inner card frame and backplane assembly out of the chassis taking care not to stress

any of the power cabling. Do Not remove any of the power cabling to the backplane. Turn

the assembly slightly and rest it on the main chassis assembly. Repeat this step with the

spare Model Processor chassis.

• For each card in an ISA bus slot (except the CPU card), remove the screw securing the card

to the chassis.

• If there is a ribbon cable connecting some of the cards together, remove it. Remember where

it was connected: it will have to be reinstalled.

• For each card in the old model processor, remove the blank mounting bracket in the corre-

sponding slot of the spare model processor. This is done by unscrewing the screw on the top

of it holding it in place.

• Remove each card from the old model processor and reinsert it into the new chassis. Place

the cards in the same location in the new chassis to avoid any confusion.

• If there was a ribbon cable connecting cards together, reinstall it.

• Secure the mounting brackets of the cards by screwing them to the chassis. There is one

screw securing each card.

• Place the card assembly carefully back in the chassis, taking care to avoid any pinched

cables.

• Replace the top of the chassis to the spare system and install the screws.

• Reattach all cables.

• Insert the DOS installation disk in the A: drive.

• Perform power up sequence described in Chapter 4, DACS Operation.

• When the A: prompt is displayed, perform the cold start procedures listed in the following

section starting from the Operating System Installation section. For convenience, all spare

Model Processor modules have the CPU BIOS preset and the hard disk partitioned and for-

matted before shipment.

• Restore back up of user created ﬁles and directories.

The DACS is now ready for use.
