Chapter 3
Subsystem Set-Up
This chapter gives step-by-step instructions on how to unpack, mount, and cable up the various
disk and tape subsystems which may be supplied with either the Modell00U or Model 150U.
This chapter also gives directions on how to add a second Fujitsu M2312K (84-MByte unCormat-
ted), M2284 (169-MByte unformatted), or M2351 (474-MByte unCormatted) drive to an existing
Sun system. For details on configuring disk/tape controller boards, see the Hardware
Configuration and Ezpan,ion chapter.
3.1. M2312K (Fujitsu 84-MByte) Disk
Your Sun Workstation may be supplied with a disk subsystem which is the Fujitsu Model
M2312K disk drive. The Fujitsu disk drive uses the industry-standard SMD interface which is
supported by either the Interphase SMD 2180 disk controller or the Xylogics 450 SMD disk con-
troller supplied with your disk subsystem.
Note
that iC you are upgrading Crom an Interphase controller to a Xylogics controller, the DIP
switches on the top surface
oC
the disk drive must be re-set. For an Interphase controller, the
proper settings are: on DIP Switch 2, switches 2, 4, 5, and 7 ON; switches 1, 3, and 6 OFF; on
DIP Switch 3, switch 3 ON; all others OFF. For a Xylogics 440 or 450 controller, the proper
settings are: on DIP Switch 2, all switches ON; on DIP Switch 3, switch 3 ON; all others OFF.
Two disk drives may be attached to a single SMD controller. Fujitsu disk drives are shipped in
a box nested inside another box. The package containing the disk drive is wrapped in a plastic
bag. To unpack, mount, and cable up the subsystem, Collow the procedures below.

1. Open the disk's shipping carton by cutting its binding straps with a kniCe or scissors.
2. Open the outer shipping carton and remove the top styroCoam piece. This exposes packing
Coam containing severai components (these vary depending on your system configuration):
manuals, a power cord, Ethernet cables and transceiver, mouse and pad, and - for a 150U
only - the mounting hardware Cor the disk subsystem. Remove these items and set them
aside.
