Optional Components

Optional components are described in the following subsections.

Monitor, Keyboard, and Mouse

The system does not require a monitor, keyboard, or mouse for most server management functions other than the initial boot, system upgrading, or system troubleshooting.

USB-compatible keyboard and mouse connectors are available on the rear of the system.

Support for a colored VGA monitor is also available by using the VGA monitor connector available on the rear of the system.

System Features

The following subsections provide a description of the system features.

Xeon Processor

Depending on system configuration, each CPU CRU can include up to two Xeon 2.4GHz processors, see Figure 1-7. Each processor is mounted on the CPU board located in the CPU module. Each processor plugs into a Zero Insertion Force (ZIF) socket on the board. The processor features a 512 KB cache. An optional second Xeon processor enhances performance and allows Symmetric Multiprocessing (SMP).

System Memory

Up to 3 GB of Synchronous Dynamic Random-Access Memory (SDRAM) can be configured on the CPU board located in the CPU module. The CPU board contains six 168-pin DIMM sockets allowing for system memory expansion within a CPU module. See Figure 1-7.

Note: Only use DIMMs approved for use in this server. Call your customer service representative for information.

SAF-TE Controller

The SCSI backplane has a SAF-TE (SCSI Accessed Fault Tolerant Enclosure) controller that provides an interface to a disk subsystem that supports status signals, hot swapping drives, and module monitoring.

The transport mechanism for the standardized alert detection and status reporting is the SCSI bus. Disk drives are continually monitored and the conditions are reported over the SCSI bus to the system. This allows the user to react to conditions that could normally go unnoticed until data loss.
