Remove the Motherboard
![Caution Caution](graphics/electrical.gif) | Caution - Ensure that all
power is removed from the server before removing or installing the
motherboard assembly. You must disconnect the power cables from
the server before performing these procedures. |
![Caution Caution](graphics/electrical.gif) | Caution - These procedures require that
you handle components that are sensitive to ESD. This sensitivity
can cause the component to fail. To avoid damage, ensure that you
follow antistatic practices as described in ESD Measures. |
This is a cold-service procedure that must be performed by
qualified service personnel. The server must be completely powered
down before performing this procedure. See Component Service Categories for more information about this
category of service procedures.
Note -
When replacing the motherboard, remove the SC PROM from the old
motherboard and install that component on the new motherboard. The SC PROM contains the
system host ID and MAC address. Transferring this component preserves
system-specific information. The SP is built into the motherboard, not on
a separate card as on some earlier servers.
- Prepare
for servicing.
- Attach an antistatic
wrist strap.
- Power off the server and unplug
power cords from the power supplies.
See Removing Power From the Server.

- Remove the top cover.
See Remove the Top Cover.
-
Remove the air baffle.
See Remove the Air Baffle.
- Remove all PCIe cards.
See Remove a PCIe Card or Filler.
Always remove transceivers from a PCIe card before removing the card from the server.
Keep track of which slot each PCIe card was in so you can return them to their original positions.
- Remove the SC PROM from the motherboard.
You will reinstall it on the new motherboard.
-
Remove DIMMs from the motherboard.
See Remove a DIMM.
You will reinstall the DIMMs on the new motherboard. Keep track of which slot
each DIMM came from and return them to their original position.
-
Open the fan cover and remove the fan modules.
-
Disconnect the ribbon cables from the motherboard that go to
the left and right LED indicator modules (panel 1).
The right LED indicator module include the front USB 2.0 ports. The left and right LED
indicator modules do not need to be removed to replace the motherboard.
-
Disconnect the cable from the server intrusion switch (panel 1).
-
Disconnect the signal cable and power cable from the motherboard to the drive
backplane.
See Remove the Eight-Drive Backplane.
-
Disconnect the mid-wall from the chassis.
-
Remove the screw on each side of the chassis that secures the mid-wall
to the chassis (panel 3).
-
Loosen the four green captive screws that secure the mid-wall to the bottom of the chassis (panel 4).
Use a No. 2 Phillips screwdriver to loosen the captive screws.
-
Lift the mid-wall out of the chassis (panel 5)
-
Release the power supplies and pull them slightly out of the server.
The power supplies do not need to be removed from the chassis to lift out the motherboard.
-
Lift the motherboard out of the chassis.
You can use the bar by the rear I/O panel and the metal handle in front of the cable
channel as handles to lift the motherboard. Slide the motherboard slightly
towards the front of the server and then lift it out of the chassis.
-
Place the motherboard on an antistatic mat.
- Install a new motherboard.
