                     Function                             Location

  50-pin SCSI bus 1 connector - internal                     P1

  adapter

  Note: There are four versions of the SX4000 expansion module: SX4000/1,
  SX4000W/1, SX4000/2

  and SX4000W/2. The first two modules have a single SCSI connector (P1).
  This adds one bus,

  supporting seven additional devices on the PM3222 and an additional
  fifteen on the PM3222W.

  Expansion modules SX4000/2 and SX4000W/2 each have two SCSI connectors
  (P1 and P2).

  This adds two buses, permitting the PM3222 to support an additional 14
  devices, and the

  PM3222W to support an additional 30.

  Proprietary connectors P15B and P16B are on the reverse side of the
  expansion module.

  Notes: Although not shown above, 1MB, 4MB and 16MB SIMMs can be
  combined and DPT ECC SIMMs

  can replace parity SIMMs of 4MB or 16MB. Single sided SIMMs are
  preferred, but low-profile

  double sided 2M and 8MB increments are supported.
