D.1 Single-System Installation of an DECarray
This section provides the procedures for installing the DECarray in a single-
system configuration correctly and safely. Digital Multivendor Customer
Services or trained installing personnel must perform the procedures.
Make sure that all precautions for site preparation have been completed.
The procedures provide the steps to:
Inspecting the array for proper configuration (Section D.1.1)
Cable the DECarray with an existing VAX 4000 system in the single-
system configuration (Section D.1.2)
Verify the DECarray for correct operation (Section D.1.3)
D.1.1 Inspecting the Storage Array (Single-System)
This procedure describes the steps to inspect the DECarray for correct
configuration.
At the front of the DECarray:
a. The DSSI ID switches behind the door of the operator control panel (OCP)
of every SF7x enclosure installed are set according to Table D–1 and
Figure D–2.
b. The Mass Storage Control Protocol (MSCP) switch (right-most switch of
each switch pack) should be in the down or enabled position at all times
unless you are instructed to change it to the up or disabled position.
