7. Gently distribute the thermal grease and remove any excess so that only an extremely thin, uniform layer remains. If any voids or crevices appear that could lead to air pockets, reapply the grease until you achieve a thin but compact consistency.
8. Use an alcohol pad to remove all thermal grease from the bottom of the heatsink.
9. Inspect the heatsink for dust and lint. Clean if necessary.
10. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.
|
Caution - If the heatsink is moved too much during its installation, the layer of thermal grease may become uneven, leading to component damage. |
11. After the heatsink is correctly aligned, reinstall the heatsink clips so that the longer tab points toward the fans.
12. Tighten the heatsink clip securing screws.
13. Replace the CPU card into the server (see FIGURE 5-15):
a. Carefully align the rear corners of the CPU card with the plastic alignment tracks inside the server chassis, then slide the CPU card into the tracks.
b. Press in firmly and evenly on both corners of the CPU card until it engages the backplane.
c. Lock down the two plastic latches on the corners of the CPU card to secure it in place.
15. Replace the front bezel onto the server.
The system battery is a common CR2032 calculator battery.
You might need to replace the system battery if you know it is weak or if after any period of AC power loss, the BIOS loses its CMOS settings or if the time-of-day clock loses time.
|
Caution - Do not attempt to open or service batteries. The battery contains lithium and can explode if not properly used, handled or disposed of. |
1. Power off the system and remove the cover as described in Powering Off the Server and Removing the Cover.
2. Remove the power-supply cage assembly: see Replacing a Power-Supply Cage Assembly.
3. Remove the system battery by sliding it back and prying it from the holder (see FIGURE 5-33 for the location).
4. Install the new system battery into the holder with the side labeled "+" facing up.
5. Reinstall the power-supply cage assembly: see Replacing a Power-Supply Cage Assembly.
6. Check the routing of all cables for obstructions and then reinstall the cover.
The following procedure describes how to remove and replace the following cables:
1. Power off the system and remove the cover as described in Powering Off the Server and Removing the Cover.
2. Identify the cable to be replaced (see FIGURE 5-34 for the location).
Refer to for the methods used to release cables from the various types of connectors.
3. Check the routing of all cables for obstructions and then reinstall the cover.
|
Caution - Use caution when removing cables because connectors and pins are very fragile and can be damaged. |
The Super-CRU is a chassis swap that requires you to replace any components that are not already shipped as a part of the Super-CRU. To install a Super-CRU, you must remove the CRUs in the list below from the system that you are replacing. Then, transfer all of those components to the new Super-CRU chassis.
1. Power off the system and remove the cover as described in Powering Off the Server and Removing the Cover.
Some procedures might not require you to remove the cover. Refer to the individual instructions as indicated.
2. Remove the following components and transfer them to the new Super-CRU chassis.
Refer to the appropriate instructions in this chapter to remove and replace each component. Also refer to FIGURE 5-2 for component locations.
FIGURE 5-36 shows the locations of the activity indicator LEDs and the Clear-CMOS jumper on the motherboard and the optional CPU card. TABLE 5-3 defines the component to which each fault indicator LED corresponds.
Jumper J125, the clear-CMOS jumper, is explained in Clear-CMOS Jumper.
TABLE 5-3 defines the activity indicators that are shown in FIGURE 5-36. The LED numbers are intentionally duplicated between the motherboard and the CPU card.
Jumper J125, the clear-CMOS jumper, is explained in Clear-CMOS Jumper.
All other jumpers and switches are for internal factory troubleshooting and are intentionally not documented in this guide.
The location of the Clear-CMOS jumper (J125) on the Sun Fire V40z motherboard is shown below. This jumper can be used to clear the CMOS if the server hangs during certain conditions.
