(2) Remove the Processor Module as follows:
a. Unfasten two (2) intermodule captive fasteners on
the rear of the module.
b. Slide the Processor Module back and disengage from
the guide posts on the Disk/Tape Module.
c. Remove the Processor Module and set aside.
(3) Examine all Disk/Tape Module cable harnesses for signs
of stress (broken terminals, loose or broken wires,
broken cable straps).
(4) Make sure all harness connectors are securely fastened
to their mating connectors.
(5) Model 21: Check that the rotary-arm shipping lock on
the FINCH Disk Drive (locate.d atop the environmental
enclosure) is in the SHIP position (heads locked).
Model 31: For SMD drives, check that the locking lever
at the bottom front of the drive is in the SHIPPING
(locked) position.
(6) Verify the AC line voltage set on the power supply with
the AC voltage specified on th~ module ID plate. If
there is a difference notify Zilog Fieid Service.
(7) Reassemble and interconnect the system by reversing
steps 2 and 1.
NOTE
. AC line voltages are switch selectable. A SWITCH
POSITION/LINE VOLTAGE selection matrix is
silkscreenedon the power supply cover; shown are
the available line voltages.

WARNING
The line volt;age setting must only be
per~ormed
by
Zilog Field Service personnel. Improper switch
settings could damage the system.
This illustration shows switches S1 and S2 set for
