Caution

The heat sink has Thermal Interface Material (TIM) located on the bottom of it. Use caution when you unpack the heat sink so you do not damage the TIM. If you are reusing the original heatsink, make sure that the TIM on the bottom of the heatsink is not damaged. If the TIM is damaged, you should remove the old TIM and, then apply new TIM to the bottom of the heatsink.

10Place the heat sink on the installed processor (2), making sure that the locking tab on the socket goes through the hole in the heatsink.

11Push down the heat sink retaining levers (3) and lock them under the retaining hooks on the heat sink socket.

12Follow the instructions in “Closing the server case” on page 30.

Replacing a power supply module

Caution

The power supplies in this server contain no user-serviceable parts. Only a qualified computer technician should service the power supplies.

Your server comes with 3-wire AC power cords fitted with the correct plug style for your region. If this plug does not match the connector on your surge protector, UPS, or wall outlet, do not attempt to modify the plug in any way. Use a surge protector, UPS, or wall outlet that is appropriate for the supplied AC power cords.

Your server uses as many as two 650 W hot-swappable power supply modules. If your server has both power supply modules installed, the modules act as redundant, hot-swappable power supplies. If one of the two power supplies fails, the other power supply supports the server while you replace the failed power supply. You do not need to turn off the server or disconnect peripheral devices to replace a failed redundant power supply.
