Replacing the motherboard

About replacing the motherboard

Replacing the motherboard consists of the following procedures:

Removing the motherboard tray

To remove the motherboard tray, complete the following steps.

Caution
To prevent shorting the NVRAM 4 battery, you must perform this procedure on a nonconductive surface. Shorting the NVRAM 4 battery causes data loss.

Step	Action
1	Shut down the storage engine by entering the following command at the console: halt
2	Open the PCB carrier by following the procedure described in Opening the PCB carrier. Note When the motherboard fails, the storage engine 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 NVRAM 4 adapter.
3	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.
4	Remove the memory card assembly by following the procedure described in Replacing the memory card assembly.
5	Remove the PCB carrier from the storage engine chassis by following Steps 2 through 4 of the procedure described in Removing the PCB carrier.
6	Unscrew the slides from the PCB carrier using a #2 Phillips screwdriver and set them aside for your replacement motherboard. The motherboard tray includes the PCB carrier, empty of all other FRUs.

Installing the motherboard tray

To install the motherboard tray, complete the following steps.

Step	Action
1	Using a #2 Phillips screwdriver, secure the rails on the side of the PCB carrier.
2	Install the memory card assembly by following the procedure described in Replacing the memory card assembly.
3	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.
4	Pull the inner slides from the storage engine's chassis to full extension, then carefully align the PCB carrier rails with the inner slides.
5	Slide the PCB carrier into the storage engine chassis. Note If the PCB carrier gets stuck while the inner slides are extended, reach inside the storage engine chassis and hold the locking mechanism straight so that the slides are not obstructed.
6	Reconnect the storage engine to the your network.
7	Reconnect the storage engine to AC power, and power on.

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