Figure 38. Applying thermal grease on the top of the processor
1. processor
2. thermal grease
3. thermal-grease syringe
NOTE:
The thermal-grease is intended for one-time use only. Dispose of the syringe after you use it.
c) Place the heat sink onto the processor.
d) Tighten the four screws to secure the heat sink to the system board.
NOTE:
Tighten the screws diagonally opposite to each other. Do not over-tighten the heat sink retention screws
when installing the heat sink. To prevent over-tightening, tighten the retention screw until resistance is felt, and
stop once the screw is seated. The screw tension should be no more than 6 in-lb (6.9 kg-cm).
1. Install the cooling shroud.
2. If applicable, install the PCIe card.
3. If applicable, install the cooling fan assembly.
4. Follow the procedure listed in After working inside your system.
5. While booting, press <F2> to enter the System Setup and check that the processor information matches the new system
configuration.
6. Run the system diagnostics to verify that the new processor operates correctly.
Power supply units
Your system supports:
• Two 1100 W AC power supply modules
NOTE:
Titanium power supply unit is nominally rated for 200 VAC to 240 VAC input only.
NOTE: When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without
redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUs
when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs will be put into standby when system
utilization is low in order to maximize efficiency.
