Cabinet Temperature Query Test [for
Non-Variable Speed Fans] (#122)
This test queries the Maintenance/Tape Processor in a Standard system PPN, the
Duplication Interface circuit pack in a PPN for a High or Critical Reliability system,
or the EPN Maintenance circuit pack in an EPN for the status of the cabinet
sensors in the cabinet that contains non-variable speed fans.
NOTE:
The descriptions for Error Codes 1 and 2 (FAIL) in the following table are
reversed for Generic 1 systems that use a TN731B maintenance circuit
pack. That is, Error Code 1 indicates an “over temperature” problem while
Error Code 2 indicates and “air flow” problem. If you are servicing a Generic
1 system, be sure to follow the proper service strategy.
