FCO 885BA-F002 Rev B, Memory box intermittently fails from pwr fail

This Field Change Order (FCO 885BA-F002 Rev B) addresses a problem in 8820, 8830, and 8840 systems where the memory box intermittently fails to power up after a power failure or power-on command. The solution involves a two-part modification: updating the console software (kernals to revision D1 and 630PS to D3), and installing a MOV Sense Filter Cable (part number 17-02438-01) to the MOV sense line in the memory box. The document provides detailed installation instructions, including steps for system shutdown, cable connection to the 880-A power controller, and power-up procedures. The console must be at revision 8.0 or higher, and the estimated installation time is 2.5 hours.
