Note: The sense line for TEMP goes through a thermal switch in
the equipment cabinet fan panel to +5-V2 in Card Cage
No.4. High tempera tures open the thermal swi tch which
simulates a power failure. If +5-V2 fails, the +5-V2
and TEMP LED's may both be lighted. However, the TEMP
LED may remain lighted with the +5-V2 LED not lighted.
*On I-Bay Models +5-V3 is internally connected to +5-V2
and, if +5-V2 fails, one or both +5-V2 and +5-V3 LED's
will be lighted.
10-3. POWER SUPPLY ADJUSTMENTS
All HP 32435A Series III Computer System power supplies have vol-
tage and current limit adjustments located at the rear of each
power supply. The HP 633l2F~P02 and HP 62605M-P3l power supplies
are accessed by opening the rear door of the equipment bay(s).
The HP 633l2F-P09 and HP 6l3l5D-P07 power supplies are accessed
by opening the rear door of the equipment bay and then removing
the fan panel located at the bottom of the bay. The current lim-
it adjustments should never be attempted and voltage adjustments
should only be performed when a particular voltage is out of tol-
erance.
