Power Supply Interfaces (Opto-couplers)
The chassis has two power supply interfaces, also referred to as opto-
couplers, in the lower right corner of the rear panel. The active master
controller card uses the interfaces to obtain status information from the
power supplies. The interfaces are shown in Figure 32. The controller card
uses the top interface to communicate with the power supplies in slots A
and C, and the bottom interface to communicate with the power supplies in
slots B and D.
