Procedure 27: Upgrading an Option 11 to an Options 21Ð81IPE Module

The Option 11 IPE Module frame is narrower than the Options 21Ð81

module frame. When converting from an Options 21Ð81 frame to an Option

11, use the same procedure as outlined below. Note that the screw holes in

the Options 21Ð81 module frame are in the same locations as the Option 11

module frame.

1Remove the IPE Module from the Option 11.
2Lay the module on its side with the outside of the disk drive card
facing up and the faceplate of the IPE Module facing you.
3Remove the SCSI terminator from the faceplate.
4Using a small Phillips screwdriver, unscrew the six screws located
on the outside of the disk drive card.
These screws are indicated by arrows printed on the disk drive card.
Set the screws and flat washers aside.
5Hold the disk drive card by the edges. Push the disk drive card away
from the faceplate, then lift it up and away.
6To separate the disk drive card from the CPU card, disconnect the
SCSI I/O cable from the CPU card at connector J14.
7Pull open the ejectors at either end of the SCSI cable plug on the
CPU card and lift the connector out of the plug.
8Disconnect the power cable from the CPU card at connector J5.
9Turn the CPU card over and remove the Option 11 bracing support.
This bracing support sits inside the module between the CPU and
disk drive cards. Hold the support with one hand while removing the
screw from the CPU board with the other.
10 Remove the six screws and flat washers securing the CPU card to
the IPE Module frame.
11 Pull the CPU card away from the faceplate and lift.
12 Place the CPU card against the Options 21Ð81 module frame,
making sure the edges of the card are securely against the
faceplate.
Line up the Abort and Reset switches with the corresponding cutouts
in the faceplate.
