Hardware Installation

Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform
the upgrade instruction procedures described at an ESD workstation
only. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a
metal part of the system chassis. If a wrist strap is unavailable,
establish and maintain contact with the system chassis throughout
any procedures requiring ESD protection.
2.2 System Memory
The system board is equipped with three 168-pin DIMM (Dual In-
line Memory Module) sockets that support unbuffered PC-133/PC-
100 SDRAM DIMM for 133MHz/100MHz system memory bus. PC
SDRAM (Synchronous Dynamic Random Access Memory) is a fast
memory interface technology that uses the clock on the chip to
synchronize with the CPU clock so that the timing of the memory
chips and the timing of the CPU are synchronized. This saves time
during transmission of data, subsequently increasing system
performance.
The system board also supports the ECC (Error Checking and
Correction) function. To use this function, you must install DIMM that
supports parity. Refer to chapter 1 (System Memory section) for
