Introduction AC Repair and Adjustment Procedures

Introduction

This document guides you in removing and replacing the field replaceable units

(FRUs) of the CRAY T3E air-cooled (AC) cabinet. This document includes a

list of FRUs, on-site spares, and tools for the CRAY T3E AC cabinet. It also

includes procedures for parts that need periodic maintenance.

This document does not contain power-on and power-off procedures. Refer to

the AC Power, Control, and Electromechanical Troubleshooting document,

Cray Research publication HMM-169-0, for power-on and power-off

procedures.

NOTE: Service personnel who are not Cray Research employees should

perform only procedures that are speciﬁed in their maintenance

agreements.

The following general instructions apply to all procedures in this document:

•Review the entire procedure before you perform any steps.

•Remember that the tools list for a given procedure does not include the

hex wrench required to open cabinet doors or the tools required to

complete additional tasks that are documented under a different

procedure.

•Label, or otherwise record the locations of, every wire or cable that you

disconnect during a procedure.

•Inspect all replacement parts for evidence of physical damage when you

receive them.

Safety and ESD Precautions

ObservesafetyandESDprecautionsduringallreplacementprocesses.Required

apparel includes an ESD smock, ESD wrist strap, and ESD shoes or shoe straps.

For further information on safety and ESD, read the Safety and ESD Guidelines,

Cray Research publication HGM-016-A.

Most CRAY T3E AC repair procedures require that you unplug the cabinet and

install, lock, and tag the plug with an electrical plug lockout device

(P/N 15255100).
