Section I: Hardware Overview
Power Supply Interfaces (Opto-couplers)
The chassis has two power supply interfaces, also referred to as opto-
couplers, in the lower right corner on the rear panel. The interfaces,
labeled Power Supply Interface, are used by the active master controller
card to obtain status information from the power supplies. The interfaces
are shown in Figure 9.
Figure 9. Power Supply Interfaces (Opto-couplers)
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.
Caution
Power supply modules are hot swappable, but power supply
interfaces are not hot swappable. Power supply interfaces should
only be serviced by an authorized service technician.
LED
Each interface has one LED, labeled Power. The LED is described in
Table 5 on page 33.
