Power Source Interfaces
The S320 OCS is powered by redundant power source inputs: Power Source A and Power
Source B. Each input holds a single -48 VDC power module. If Power Source A fails, the system
automatically draws all required power from backup Power Source B without affecting existing
cross-connections or management connectivity.
LEDs indicating power source status are located on the front panel of the switch (see section
3.3.2). In addition, each power module has an LED located at the right of the module faceplate
(Figure 10 and Figure 11) that indicates whether the module is on (LED is lit) or off (LED is unlit).
Version 1 power modules also have a Reset button located at the right of the LED; pressing this
button repowers the system if an emergency shutdown has occurred.
