6. Remove the center fan bracket. See Removing the Center Fan Bracket.
   
   
7. Unpack the tape drive (and controller card, if applicable) and configure the tape drive according to the documentation that came with the tape drive, based on the following guidelines:
   
   
   1. Each device attached to a SCSI host adapter must have a unique SCSI ID number. (Narrow SCSI devices use IDs 0 to 7; wide SCSI devices use IDs from 0 to 15). Set the drive's SCSI ID to avoid conflicts with other devices on the SCSI bus. For the default SCSI ID setting, see the documentation provided with the drive.
      
      

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.

2. SCSI logic requires that the two devices at opposite ends of a SCSI chain be terminated and that all devices in between be unterminated. Therefore, you enable the tape drive's termination if it is the last device in a chain of devices (or sole device) connected to the SCSI controller.
   
   
8. If a controller card was included in the drive kit, install the card now. See Expansion Cards.
   
   
9. Remove the filler plate from the tape backup unit bay, if applicable:

Memory

You can upgrade your system memory to a maximum of 16 GB by installing 533MHz or, when available, 667MHz fully buffered DIMMs (FBDs) in dual sets of 256-MB, 512-MB, 1-GB, or 2-GB. The memory sockets are located on the system board beneath the cooling shroud. See Figure 6-2.

NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep them separate from any new memory modules that you may have. Use only 533 MHz or, when available, 667 MHz FBDs.

The memory module sockets are arranged on the system board in two equal branches (0 and 1). See Figure 3-20. Each branch consists of two channels:

• Channel 0 and channel 1 are in branch 0.
  
  
• Channel 2 and channel 3 are in branch 1.
  
  

Each channel consists of two DIMM sockets:

• Channel 0 contains DIMM_1, DIMM_5.
  
  
• Channel 1 contains DIMM _2, DIMM_6.
  
  
• Channel 2 contains DIMM_3, DIMM_7.
  
  
• Channel 3 contains DIMM _4, DIMM _8.
  
  

The first DIMM socket of each channel has white release tabs.

Figure 3-20. DIMM Sockets

General Memory Module Installation Guidelines

To ensure optimal performance of your system, observe the following guidelines when configuring your system memory.

• Use only qualified FBDs. FBDs can be either single-ranked or dual-ranked. FBDs marked with a 1R are single-ranked and modules marked with a 2R are dual-ranked.
  
  
• A minimum of two identical FBDs must installed.
  
  
• DIMM sockets must be populated by lowest number first.
  
  
• FBDs must be installed in pairs of matched memory size, speed, and technology, and the total number of FBDs in the configuration must total two, four, or eight. For best system performance, all FBDs should be identical memory size, speed, and technology.
  
  
• Memory sparing and memory mirroring require eight FBDs, and all FBDs must be of identical memory size, speed, and technology.
  
  
• Memory sparing and memory mirroring cannot be implemented at the same time.
  
  

Non-Optimal Memory Configurations

System performance can be affected if your memory configuration does not conform to the preceding installation guidelines. Your system may issue a warning message during startup stating that your memory configuration is non-optimal.

Memory Sparing Support

The system supports memory sparing if eight identical memory modules are installed in the system. The memory sparing feature must be enabled in the System Setup program and can be used only if memory mirroring is not enabled.

Memory sparing allocates four ranks of DIMM memory to the spare bank of memory sparing. These four ranks consist of the first rank of memory in DIMM sockets 1 through 4. For single-rank DIMMs, the entire capacity of the four DIMMs is allocated to sparing whereas for dual-rank DIMMs, only half of the four-DIMM capacity is allocated to sparing. Table 3-7 shows how memory sparing splits the available and spared memory in each of the single- and dual-ranked memory module combinations.

Table 3-7. Memory Sparing Configurations 

Memory Mirroring Support

The system supports memory mirroring if eight identical memory modules are installed in the system. Mirroring must be enabled in the System Setup program and can be used only if memory sparing is not enabled. In a mirrored configuration, the total available system memory is one-half of the total installed memory.
