Command line mode test commands
Testing ensures the proper working order of the DRU’s components. Each test
result is sent to the ICP by request or regular audit. Testing can be initiated by
entering the appropriate command from the ASCII terminal, by a message
sent from the ICP, or by regular audits on the DRU. An audit test failure
initiates an alarm unless the alarms are disabled. Table 1-6 gives the name,
command, state, and action for the Command line mode test commands.

Action/Initial value
Calibration Table
Sanity Tests (For
TRU2 only) TEST EEPROM Any Calibration information is stored in EEPROM
along with an associated CRC. This test
calculates each table’s CRC and compares to
the stored CRC. If a table has not been written,
the result is ”n/a”.
DSP Sanity Test TEST DSP ALL Maint. This test checks the basic sanity of the DSPs
by checking for basic messaging ability in each
one.
Flash Load CRC
Test TEST FLASH Any This test reads all data stored in flash
EEPROM, calculates the CRC, and compares
this value against the CRC stored in the flash
EEPROM.
Individual DSP
Sanity Test TEST DSP dspid# Maint. This test is similar to the previous one except
that the sanity test is only run on a particular
DSP chip.
RAM Read/Write
Test (For TRU2
only) TEST RAM Any The read/write memory is checked to ensure
that all locations can be written to and read, and
that each address accesses a unique memory
location.
