Motherboard Replacement

Disconnect the 10G cable NIC.

Pull the green retention plunger upwards and twist 90 degrees to lock in the upright position.

Using the handle located at the left side of the server sled, pull the sled outwards.

Remove the server sled and place it onto a crash cart or work bench for service.

Disconnect the following cables by pressing down on the metal retention tabs pulling away from the HDD:

SATA cable

Power cable

Pull the two PCI Riser Cage locking handles towards the front of the server, as shown.

Lift the PCI Riser Cage from the server chassis.

Locate the Trusted Platform Module (TPM).

To remove, grip the module on each side, then pull upwards as shown.

Locate the (3) retention tabs which secure the NIC to the (4) motherboard standoffs.

To release the NIC, carefully press down on the retention tabs as shown.

Lift the NIC to remove it from the motherboard.

Disconnect the Power cable by pulling upwards on the white connector.

Disconnect the SATA cable by pressing the metal tab, then simultaneously lifting the connector upwards.

Grab the center portion of the chassis lid as shown.

Firmly pull towards the front of the server chassis to release the lid.

Lift the lid and remove

Disconnect and remove all the DIMMs.

Place all DIMMs aside for reuse with replacement motherboard.

Remove (2) heatsinks and CPUs.

Place the CPUs on top of their respective heatsinks

Close (2) CPU retention brackets.

Disconnect (2) fan power cables.

Engage the metal retention tab on the slide-to-lock panel to release the side-plane power connector.

Simultaneously slide the power connector to the right to release.

Remove the power connector from the slide-to-lock panel.

Carefully remove the motherboard power cable from in between the (2) fans as shown.

Loosen (1) thumbscrew.

Slide the motherboard toward the rear of the chassis until resistance is felt.

Lift the motherboard from the chassis.

Align (7) motherboard keys with the chassis standoffs.

Lower the motherboard into the chassis.

Slide the motherboard toward the front of the chassis until resistance is felt.

Tighten (1) thumbscrew.

Carefully guide the motherboard power cables in between the fans as shown.

Connect (2) fan power cables.

Make sure to align the key on the connector and header.

Insert the power connector into the slide-to-lock panel.

Once the connector has been inserted, slide it to the left to lock in place.

Prior to in CPU installation, thermal compound MUST be remove from BOTH the heatsink and CPU, then reapplied.

Utilize the 5-dot thermal compound method upon CPU installation.

Wipe the top of the CPU with an ispropyl alcohol pad to remove the thermal compound residue.

Multiple passes may be needed. Continue until all the thermal compound residue has been removed.

Utilize the 5-dot thermal compound method upon CPU installation.

Scrape the thermal compound from the heatsink using a plastic putty knife.

Scrape parallel to the machined grain, as shown.

Wipe the remaining thermal compound off of the heatsink with an ispropyl alcohol pad.

Wipe parallel to the machined grain, as shown.

Continue this process until no thermal compound residue remains on the heatsink.

Install all the DIMMs into their correct DIMM sockets.

Insert the SATA cable into it's socket until it clicks into place.

Insert the Power cable into the it's socket until resistance is felt.

Align the NIC onto (4) the nylon standoffs.

Press down firmly to seat the NIC.

Ensure all (4) corners are secure.

The TPM module and socket are keyed. Ensure that both are aligned prior to installation.

Once the TPM module connector has been aligned, insert it into the socket until resistance is felt.

Insert the lid onto the server chassis.

Slide it towards the rear of the chassis until it clicks into place and resistance is felt.

Align (4) PCI Riser Cage slots with the chassis keys.

Lower the PCI Riser Cage onto the server chassis and press firmly to seat.

Lock the PCI Riser Cage by pushing the two handles towards the rear of the server until they click into place.

Connect the SATA and Power cables as shown.

Insert the server sled into the rack as shown.

If the green retention plunger is still in the upright position, twist it 90 degrees to release it. This will secure the server.

Press the power button to power-on the server.
