5.5.2 Remote Sense (not implemented at this time)
Connect remote sense leads to J1-5 and J1-6, if desired. Observe correct polarity. Refer to
Figure 5-3
.
5.5.3 EPO Signal
Connect a normally open external EPO (Emergency Power Off) switch to J1-3 and J1-4, if desired. Switch closure causes the SCC
controller to send an SNMP trap, wait two (2) seconds, and then send a message to shut down the rectifiers. Refer to
Figure 5-3 .
5.5.4 Imminent Power Fail Alarm
Contacts close between J1-1 and J1-2 when an imminent power fail alarm occurs. This alarm signals when the combination of
rectifiers and batteries on the bus can no longer support the load. Refer to
Figure 5-3
and SCC Controller Instructions
(UM1M520HNA) for details.
5.5.5 SCC Controller Ethernet Connection
Connect the SCC controller’s Ethernet port (labeled RMS) to an RMS (Rack Management System). Refer to Figure 5-3 .
