5.7. Disk Power ON Procedure
This section describes the procedure for applying power to
the drive. The disk is a nonvolatile storage media; there-
fore, once data is recorded, it is not lost when power is
turned OFF.
The
following checks must be performed prior to turning
power ON:
1. Inspect the physical mounting to ensure that the drive
is secured at all mounting points, and that all ribbon
cables are securely connected.
CAUTION
Improper orientation of the power connector can
result in serious damage to the drive.
2. Place the rotary-arm shipping lock to the OPERATE posi-
tion. The shipping lock is located on the bottom sup-
port bracket on the front of the SMD drive.
3. Apply power to the drive. Observe that the actuator
mechanism performs a·first seek operation in less than
one minute (the read/write heads move from the landing
area into the data area of the disk).
5.8. Power Supply Voltages
Power supply voltages should be checked each time on-premise
maintenance is performed. This should only be performed by
Zilog Field Service personnel. Ensuring that each supply is
within tolerance 1s essential to mainta.in normal system
operations.
TEST EQUIPMENT REQUIRED: HP3466A Multimeter or equivalent
5.8.1. AC Input Voltage Check: Using the multimeter, check
RMS voltage at the facility outlet where the System 8000
will be plugged in. Ensure that the voltage reading is
within the range specified by the switch settings on the CPU
and Disk/Tape Module power supplies.
