AMPERIF PREVENTIVE MAINTENANCE
PURPOSE
1. The purpose of this Procedure is to formalize a Preventive Maintenance
(PM) schedule on Amperif equipment. This equipment includes Amperif Solid State
Drum (SSD) and controllers, cache disc subsystem controllers, data copy,
uninterrupted power source (UPS), and individual disc drives. This Procedure
should be used as a reference in scheduling, performing, and tracking
preventive maintenance on Amperif equipment.

Procedure:
a. CSD Plan CSD-81-0001 CSD Management Plan
b. CSD Instruction No. 50-0008 NDS Schedule of Operations
APPLICABILITY
3. All personnel responsible for the stability of the Amperif equipment.
All Amperif engineers performing maintenance on Amperif equipment.
POLICY
4. The Data Center Operations Branch (DCOB) is required to maintain all
NDS computers, peripheral equipment, and communications hardware as described in
the CSD Management Plan (CSD-81-0001).

PROCEDURE
6. Amperif equipment PM is to be conducted as an on-going effort. To
accomplish that effort PM will be performed in three phases: weekly, monthly,
and semi-annually.
WEEKLY PM
7. Amperif will perform weekly PM every Wednesday from 1600 to 1700 hours
except on.the first Wednesday of the month. This PM will not require an outage
to the NDS operational system. If the Amperif engineers discover a potential
fatal problem within the Amperif hardware, they will notify the on-duty Operations
Control Officer (OCO). The OCO should insure an operational system outage is
scheduled as soon as possible for corrective maintenance.
MONTHLY PM
8. Amperif will perform monthly PM on the first Wednesday of the month
from 1900 to 2200 hours. The Operations Support Section (OSS) is required to
schedule a operational system outage for this period. Prior to Amperif PM,
Data Center Operations Section (DCOS) personnel will copy the SSDs to tape. This
tape will be used to verify the data copy feature of the SSDs. SSD data is to be
restored from tape if the data copy does not verify correctly. Amperif will
check the UPS for proper charge, check and log air flows for each disc drive, and
insure proper operation of data copy feature for the SSDs and cache.
SEMI-ANNUAL PM
9. Amperif will perform semi-annual PM on individual disc drives, assuring
all drives have,been checked, voltages adjusted, cleaned, and inspected during
the six-month period. This PM can be performed on-line with no operational
system outage. At opportune times the DCOS will substitute a spare drive for an
operational drive, on advice from the OCOs, to insure that Amperif will always
have a drive to PM. The OCOs are responsible for tracking which drives have
or have not had semi-annual PM.
10. The Operations Support Section (OSS) will notify Amperif maintenance of
extended NDS computer system outages if these outages do not require use of
Amperif equipment. Amperif will be scheduled to use this time to perform any
maintenance they feel necessary.
