| Caution - If you operate the chassis with an empty server module slot, it is possible that you will notice a reduction in the performance of your system.

##

3.5 Removing or Replacing Filler Panels

Each server module arrives with module-replacement filler panels for CPUs, storage drives, and memory modules. These filler panels are installed at the factory and must remain in the server module until you are ready to replace them with a purchased module.

A filler panel is a metal or plastic enclosure that does not contain any functioning system hardware or cable connectors. These panels must remain in any unused module slots (storage drives, DIMMs, and CPUs) to ensure proper air flow throughout the system. If you remove a filler panel and continue to operate your system with an empty module slot, the operating performance for your system could decline.

### Remove or Insert Filler Panels

To remove or insert server module filler panels follow the procedures in TABLE 3-1.

5. Close the release lever until it clicks into place and is flush with the front of the server.

#### 3.7.1.2 HDD or SSD Failure and RAID

A single storage device failure does not cause a data failure if the storage devices are configured as a mirrored RAID 1 volume (optional). The storage device can be removed, and when a new storage device is inserted, the contents are automatically rebuilt from the rest of the array with no need to reconfigure the RAID parameters. If the replaced storage drive was configured as a hot-spare, the new HDD is automatically configured as a new hot-spare.

| Caution - Possible data loss: If you insert a storage device that has been configured with a RAID volume into a server that did not previously have its storage devices configured with RAID volumes, the existing storage devices in the server will be converted to RAID volumes during automatic synchronization and any existing data on the existing storage devices in the server are erased. Before you permanently remove a storage device from the server that is part of an active RAID volume, you should delete the active RAID volume from the storage device. For information on how to delete a RAID volume, use the appropriate RAID management utility for the RAID controller installed.

For information about the implementation of RAID on this server and references to RAID controller documentation, refer to the Sun Disk Management Overview For X64 Sun Fire and Sun Blade Series Servers, 820-6350.

Note - The heatsink is not symmetrical, and it must be aligned with the silkscreen on the PCB before you place it on the CPU.

d. Lower the heatsink onto the CPU, aligning the mounting screws with their holes on the motherboard.

Each heatsink has a long-ear tab and a short-ear tab through which the screws attach to mounting studs. See Frame 1 of FIGURE 3-15. To correctly orient the heatsinks, position each long-ear tab closest to the DIMM slots associated with that CPU. The final result will show the heatsinks lined up evenly in the front and rear with silkscreen lines on the motherboard.

e. Using an allen wrench, alternately tighten the two heatsink mounting screws, 180 degrees at a time, until each spring is completely compressed.

Tighten the screws to 7 in.-lbs (0.8 Nm).

6. Reinstall the cover on the server.

### 3.7.7 Cabling the FEM, REM, and Disk Drives

The FEM, REM, and disk drives on the server module require different cabling depending on the option that is chosen. FIGURE 3-19 shows the FEM and the REM installed and cabled directly to the disk drives.

Identify the Proper Cabling Paths

FIGURE 3-19 illustrates cabling paths for the REM (1) and hard drive power (2).

1. Use the REM SAS cable (see cable 1 in FIGURE 3-19) to connect the REM to the hard disk or solid state drives.

Note - The hard disk drive and solid state drive connect to either the REM or the onboard chipset.

2. Use the power cables (see cable 3 in FIGURE 3-19) to provide power to the disk drives.

Connect Disk Drives to the Onboard Chipset

FIGURE 3-20 illustrates the cabling scheme used to connect the disk drives directly to the onboard chipset.

1. Use the ICH10 R SATA cable (see cable 3 in FIGURE 3-20) to connect the HDD or solid state drives to the onboard chipset.

| Caution - The ICH10 R SATA cable jacks are sized to fit the blue or black onboard connection. Do not force the jacks when making a connection.
