Dell PowerVault 2xxS Storage Systems SCSI Backplane Board Replacement Instructions

Install the Replacement SCSI Backplane Board

To install the replacement SCSI backplane board, perform the following steps:

1. Place the board between the chassis halves. Ensure that the board is right

side up and the dual-bus split backplane module faces the back half while

the eight hard-disk drive connectors face the front half.

2. Using the magnetized 11.5-inch–long, 5/64-inch ball-head Allen driver,

thread two screws through the left enclosure services module bay,

through the screw holes in the backplane board, and into the screw holes

of the front half of the chassis. Turn the screws until they catch in the

screw holes of the front half of the chassis. Do not tighten the screws at

this time. Install the two screws in the right enclosure services module bay

in the same manner.

NOTE: The magnetized 11.5-inch–long, 5/64-inch ball-head Allen driver

(included in the service kit) makes it easier to install the screws in the

enclosure services module bays.

3. Thread the eleven remaining screws through the inside of the component

area of the back chassis half, through the screw holes in the backplane

board, and into the screw holes of the front half of the chassis. Turn the

screws until they catch in the screw holes of the front half of the chassis.

Do not tighten the screws at this time.

NOTE: If the front half of the chassis is slightly bowed down, making it dif-

ficult to align the screw holes, try installing a hard-disk drive temporarily

into one of the center drive bays. The hard-disk drive should straighten the

bow in the chassis, making it easier to thread the screws. Remove the

hard-disk drive when all the screws are inserted.

4. Carefully insert the left enclosure services module or enclosure services

expander module into the left module bay. Push the module all the way to

the back of the bay and at the same time adjust the backplane board so

that the board connector aligns with the module connector. Push the mod-

ule until it is seated in the board connector.

NOTE: Temporarily installing the enclosure services modules or enclosure

services expander modules and seating their connectors to the connectors

on the backplane board ensures that the backplane board will be aligned as

the two chassis halves are screwed together.

5. Using a Phillips-head screwdriver, tighten the screw to secure the enclo-

sure services module or enclosure services expander module to the

chassis.

6. Repeat steps 4 and 5 for the right (second) enclosure services module,

enclosure services expander module, or terminator blank.

7 . Tighten the eleven screws on the inside of the component area to secure

the chassis front, backplane board, and chassis back together.

8. Using a Phillips-head screwdriver, loosen the captive screws at the top of

the enclosure services modules.
