Replacing the motherboard tray

Shut down your gateway by entering the following command at the console:

halt

Open the PCB carrier by following the procedure described in Opening the PCB carrier.

Note
When the motherboard fails, your gateway performs a "dirty shutdown." This prevents you from performing the recommended clean shutdown. However, the data from the last transaction is still buffered in the battery-backed memory on the NVRAM4 adapter.

Remove all adapters by following Steps 2 through 6 of the procedure described in Removing an existing expansion adapter.

If your PCI expansion adapters are secured by screws, set the screws and adapters aside for later use.

Remove the memory card assembly by following the procedure described in Replacing the memory card assembly.

Remove the PCB carrier from the chassis by following Steps 2 through 4 in Removing the PCB carrier.

Unscrew the slides from the PCB carrier and set them aside for your replacement motherboard tray, which includes the PCB carrier, empty of all other FRUs.

Using a #2 Phillips screwdriver, secure the rails on the side of the PCB carrier.

Install the memory card assembly by following the procedure described in Replacing the memory card assembly.

Reinstall all other adapters into the expansion slots on the motherboard by following Steps 3 through 6 of the procedure described in Installing an expansion adapter.

Pull the inner slides from your gateway's chassis to full extension, then carefully align the PCB carrier rails with the inner slides.

Slide the PCB carrier into your gateway chassis.

Note
If the PCB carrier gets stuck while the inner slides are extended, reach inside your gateway chassis and hold the locking mechanism straight so that the slides are not obstructed.

Reconnect your gateway to your network.

Reconnect your gateway to AC power and power it on.

Download the latest firmware version for your gateway.

Run diagnostics for your system. See the Diagnostics Guide for more information.
