System Memory

System memory has a minimum of 16 MB of 72-bit wide, buffered, EDO-type memory. The system memory capacity can be expanded up to 256 MB by using combinations of 16-, 32-, and 128-MB buffered, EDO-type dual in-line memory modules (DIMMs).

The system board has four, 168-pin DIMM sockets. The DIMMs can be mixed. The socket population rules are as follows:

•Populate the DIMM sockets in order from DIMM_A (lower) to DIMM_D (upper).

•The DIMMs should be rated at 60 nanoseconds (ns) or faster. All of the sys- tem memory operates at the speed of the slowest DIMM installed.

•The largest capacity DIMM should be in socket DIMM_A with the smaller capacity DIMMs installed in decreasing sizes toward socket DIMM_D.

The 72-bit wide, buffered, EDO DIMMs support the ECC feature that detects memory errors and corrects single-bit memory errors. The ECC feature pro- vides more reliable memory and less downtime. The ECC feature is built into the memory controller on the system board.

See “DIMMs” in Chapter 4 for information on removing and replacing DIMMs.

Advanced Expansion Subsystem

The computer system offers advanced expansion subsystems that can support a mixture of traditional EISA expansion cards, Plug and Play ISA expansion cards, and PCI expansion cards. The EISA Configuration Utility included with the system provides a means of avoiding resource conflicts that might arise from such an arrangement.

After all legacy cards have been configured with the EISA Configuration Utility, the system automatically assigns any required memory space, IRQ lines, and DMA channels to any installed Plug and Play ISA expansion cards and PCI expansion cards the next time the system is rebooted. Chapter 5, “Using the EISA Configuration Utility,” in the User’s Guide describes the EISA Configura- tion Utility and provides instructions for using it to configure the system.

The six expansion-card slots include three EISA expansion-card connectors and three PCI expansion-card connectors. The expansion-card connectors are located on the system board (see Figure 1-11).

Integrated Server Management

The system board contains integrated server management circuitry that moni- tors whether the system cooling fan is running, as well as critical system voltages and temperatures. The integrated server management circuitry works in conjunction with the Intel LANDesk® Server Management suite.
