Expanding the Server Configuration
As server/client needs grow, you can expand the system by adding processors, memory, drives, and power
supplies. Following is a description of the expandability limits for the above components:
•
The primary system board and the secondary system board have two slots each for processor boards.
Either a processor board or a bus termination board must be plugged into each processor board
connector.
•
4 GB memory board supports 16 DIMM (Dual Inline Memory Module) devices for a minimum
memory size of 128 MB up to a total of 4 GB of memory. Maximum of two memory boards for dual
system board configurations.
•
The primary system board has four EISA and seven PCI slots for add-in boards. (The fourth add-in
board slot from the bottom is a shared PCI/EISA bus slot. The term “shared” indicates that there is a
PCI and an EISA slot accessible from one external add-in board slot.) The secondary system board
has eight PCI slots.
•
Chassis can hold 17 drives: 12 hot-swap bays for 3.5-inch SCSI-2 SCA (Single Connector
Attachment) hard drives; four 5.25-inch half-height bays for removable media drives; one 3.5-inch
bay with diskette drive already installed.
•
Chassis supports from one to three power supplies.
