1.1 Scope
This document provides the operating procedures for the Amperif Solid
State Drum (SSD) Subsystem.
1. 2 Power-Up'Procedures
Power-up the three UPS units associated with the SSD system. This

96 volts.
1.2.2 Power-Up Amperif Solid State Drums (SSD)
The SSD system consists of.seven cabinets. The two outside cabinets on
the left and right sides of the system contain the solid state drums. The
three center cabinets contain the central system with the cabinet on the
right housing channel "B" and the cabinet on the left housing channel "A".
The center cabinet (of the seven) contains the control unit. To power-up the
SSD system:
a. Assure that the UPS is in the BY PASS mode.

current Time will appear on the display unit. If
the time. is. incorrect repeat step a.
c. Remove WRITE PROTECT from the data copy drive and
the system is ready for normal operations.
1.4 Power Down Procedures
The SSD system provides two methods for powering down the system. One
is caused by a power failure and is automatic. The second is a manual opera-
tion performed by the operator.
1.4.1 Power Failure
The SSD System has the capability to save all Solid State Drum and
system data on the Data Copy Drive in case of impending power loss. Three
Data Copy Lights are provided to monitor the data copy procedure. These
are located in a small box that is installed on top of the control unit. The
first light, the yellow POWER FAIL light, denotes that power has been lost,
and the system is running off the battery. If power is restored within one
minute, this light will go off and the system returns to normal operation. If
power is lost for more than one minute, the SSD System assumes that power may
not be restored before the battery is exhausted and it is necessary to save
all SS Drum and system data on disk to prepare for complete power loss. The
second light, the green DATA COPY light, denotes when this procedure is in
process. This takes only a few seconds. The third light, the red SHUT DOWN
AUTH light, denotes when data copy is complete, and the system is prepared
for complete power loss. The system may now be powered down safely.
When powering up after a power failure, all Cache data may be restored
to the pre-power failure state. This is done by doing a Data Restore
after the cabinets have been reset and the SSDs are powered up. (Ref. Paragraph
1.3)
