Installing the System Running JET Software Running JET Software 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," on page 275. 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.
