Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a
static-protected mat or surface. For more information, see “Handling static-sensitive devices” on page xix.
Perform the following steps to replace the VRM:
1. Align the VRM in the connector.
2. Press both sides of the VRM downward until the latches click into place.
3. If you are replacing the microprocessor, perform the steps required to do so. If not, replace the SAN
Volume Controller 2145-8F2 or SAN Volume Controller 2145-8F4 top cover.
4. Place the node in the rack. See “Replacing the SAN Volume Controller in a rack” on page 48.
5. Reconnect the fibre-channel and Ethernet cables. Ensure that you replace the fibre-channel and
Ethernet cables in the same ports from which they were removed.
6.
Turn on the node.

DANGER
Multiple power cords. The product might be equipped with multiple power cords. To remove all
hazardous voltages, disconnect all power cords.
You must remove and replace the microprocessor when you replace the system board. Ensure that you
have alcohol wipes and thermal grease available to correctly perform this task.
Before you proceed with the system board removal, ensure that you do the following:
v
Have a static-protected surface available to hold the components that you remove from the old system
board.
v
Follow all standard safety and handling instructions. The components that you will be handling are
electrostatic-discharge sensitive. Take precautions to avoid damage from static electricity. Wear an
anti-static wrist strap and use a static-protected mat or surface. For more information, see “Handling
static-sensitive devices” on page xix.
This service action requires you to remove the cover and:
v
Turn the node off.
v
Disconnect the power cables.
v
Disconnect the data cables.
Notes:
v
You must remove a number of components before you can remove and replace the system board. You
will reuse all the components with the new system board. Therefore, take care when you remove and
store these components.
v
Each connector on the system board has its use printed next to it on the board.
v
All left or right observations are when you are looking at the front of the unit.
To remove the system board, perform the following steps:
