The JTAG Utility for Scan Tests (JUST) Exploration Tool, or JET, collects system information for each system on a network and places it in files for use by other scan tools. JET gathers configuration data by executing a series of queries targeted at the MP and the CLU portion of the UGUY board.

JET is described in Appendix G “JUST Exploration Tool”.

IMPORTANT: Any problems encountered must be resolved before booting the operating system.

Power Cycling After Using JET

Whenever JUST has been run, system power must be recycled, because the off-line diagnostic can deallocate the CPUs.

Remove 48 Volts via the MP command, pe, then cycle the AC breakers on the rear of the cabinet(s). See Appendix B “Powering On and Off the System” for details on power cycling the system

If the complex has any IOX cabinet(s), IDs 8 or 9, it is very important to power cycle these cabinet(s) in the proper sequence.
