Working Safely Inside the Xserve

Always touch the Xserve enclosure to discharge static electricity before you touch any
components inside the Xserve. To avoid generating static electricity, do not walk around the

room until you have nished working inside the server and have replaced the cover. To minimize

the possibility of damage due to static discharge, wear an antistatic wrist strap while you work
inside the Xserve.

Warning: Always shut down the Xserve and disconnect the power cords before opening
it to avoid damaging its internal components or the components you are installing. Don’t
open the server while it is turned on. Even after you shut down the Xserve, its internal
components can be very hot. Let it cool before you open it.

Tools Required

The only tool required for this procedure is a Phillips #1 screwdriver.

Removing the Xserve from a Rack

Warning: Always shut down the Xserve before opening it to avoid damaging its internal
components or the components you want to install or remove. Don’t open the Xserve
or try to install or remove items inside while it is turned on. Even after you shut down
the Xserve, its internal components can be very hot. Let it cool down for 5 to 10 minutes
before you open it.

Unplug all cables from the Xserve. 3.

Latches

Thumbscrews

Unscrew the two
captive thumbscrews.

Slide the cover back and lift it off.

Note: If you have trouble releasing a cable from the back panel, try using a small screwdriver

or other at tool to depress the tab on the cable connector.

To avoid inadvertently unlatching a drive module during handling, use the enclosure key to 4.
lock the enclosure lock on the front panel.

Touch the server’s metal case to discharge any static electricity. 5.

Loosen the thumbscrews at both ends of the front panel.6.

Grasp the thumbscrews and pull the Xserve forward until the safety latches engage (about 7.
halfway out of the rack).

When the safety latches engage, grip the Xserve where it emerges from the rack, press down 8.
on the latch tabs with your thumbs, and slide the Xserve the rest of the way out of the rack.

Set the Xserve on a at surface and unlock it. 9.

Opening the Xserve

Loosen the thumbscrews at the back of the top cover and slide the cover back and up to remove

it. If you have diculty removing the cover, check the enclosure lock on the front panel.

Warning: Even after you shut down the Xserve, its internal components can be very hot. Let
it cool before you open it.

Important: To minimize the possibility of damage to Xserve components due to static discharge,

wear an antistatic wrist strap, if possible, while you work inside the Xserve.

Removing the Optical Drive Cable

Note: Before removing the optical drive cable, you must remove the airow duct and fan array.

Airow Duct

Loosen the ve Phillips screws that fasten the airow duct to the fan array.1.

Pull up on either side of the airow duct, and lift it straight up and out of the Xserve. 2.

Caution: Try not to completely remove the screws from the airow duct. Tiny black rubber
washers hold these screws captive on the underside of the airow duct. If the screws are

completely removed, these washers can easily fall into the enclosure and become lost.

Fan Array

Loosen the two thumbscrews that secure the fan array to the enclosure. 1.
Note: The thumbscrews are captive; you cannot remove them.

Lift the fan array to remove it from the Xserve. 2.
Note: You may need to move the front panel cable slightly out of the way of the fan array
power connector during removal or replacement. Be careful not to pinch the front panel
board cable between the fan array and any other surface inside.

Note: You may encounter some resistance around the fan array power connector during removal.
If so, carefully rotate the fan array as shown to disconnect it from the power distribution board
below, and then lift the fan array out of the computer.

Connect the replacement optical drive cable to the logic board rst. Then press the adhesive 2.
section of the cable onto the enclosure before connecting the other end of the cable to the
optical drive.

Replacing the Fan Array

Align the power connector on the fan array with its connector on the power distribution 1.
board and lower the array into the enclosure. Push down on the fan array power connector
to make sure it is fully seated.

Tighten the screws at the ends of the array. Make sure the large front panel board cable runs 2.
above the power connector but below the tab on the top of the power supply.

Replacing the Airow Duct

Lower the airow duct into position on the logic board. 1.
Note: When installing the airow duct, be sure to route both the front panel board cable and

the backplane-to-logic board I/O cable inside the channel under the left side of the duct.

Ensure the airow duct ts ush all over, and does not protrude above the level of the 2.
enclosure.

Note: Be careful when working with any black foam pieces that are part of the airow duct

or the logic board.

Tighten the ve Phillips screws that fasten the airow duct to the fan array, in the order 3.
shown, to prevent the duct from warping. Do not overtighten the screws.

and it is closed. Operating the server when it is open or missing parts can damage it or
cause injury.
