RAS96 RASCard User Guide

Introduction

The RAS96 assembly consists of a Pentium computer card to which is mounted a 2.5- inch hard disk drive, up to two optional E1 cards, and a front panel. Figure 1 shows the layout of the RAS96 card. The RAS96 assembly plugs into bus connectors on the inside of the CC9600 chassis that supply power and support data communications among the various components of the CommPlete Communications Server. The remainder of this chapter describes the RASCard’s memory banks, configuration jumpers, connectors, and front panel switches and indicators.

Memory Banks

The RASCard is shipped from the factory with 512K of L2 cache memory, which is the maximum amount that can be installed.

Two memory banks (Bank 1 and Bank 2) with two SIMM sockets per bank (M1 through M4) are provided on the RASCard. The standard configuration has 16 MB of EDO DRAM in Bank 1. The RASCard supports four 72-pin SIMMs of 4 MB, 8 MB, 16 MB, or 32 MB DRAM to form a memory size from 8 MB to 128 MB. The DRAM can be 60 ns or

70ns, fast page mode or EDO, 32-bit non-parity or 36-bit. For a list of approved SIMMs, see Appendix D.

Note: Each bank must have the same size memory installed in pairs. Always fill Bank 1 first.
