Emergency Shutdown with Emergency Power Off (EPO)
The SCC Controller has an Emergency Power Off (EPO) function operated by a remote switch provided by the
customer. 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 and BBUs.
Procedure
1.
To activate Emergency Shutdown, close the external Emergency Power Off (EPO) switch.
2.
To restart the system after an Emergency Shutdown, open the external Emergency Power Off (EPO)
switch. Then turn the AC power to the rectifiers and BBUs off then back on.
BBU Learning Mode Calibration
When the SCC gets a request for learning mode from a BBU, it will send an SNMP trap to the RMS, to indicate
that a BBU has requested learning mode. The battBatteryState field will indicate that the BBU requested
learning mode. The SCC will also change its status in the update traps to indicate that there is an alarm. The
yellow LED on the SCC will turn on.
The RMS can use the SNMP set command to set batteryLearningModeStart .N to 1 (where N is the number of
the BBU) to command the BBU to start learning mode calibration. It can also set batteryLearningModeStart .N
to 0 to command the BBU to skip this learning mode request.
If the BBU starts calibration, the SCC will send an SNMP trap to indicate that the BBU is not available. During
calibration, the BBU's battBatteryState will indicate that the BBU is in the Learning Mode calibration. During
Learning Mode calibration, the RMS can abort the calibration by setting batteryLearningModeStart .N to 0.
This will leave the calibration request outstanding, but the BBU will stop learning mode.
After calibration is completed, the SCC will send an SNMP trap to indicate that the BBU is now available. It will
also send a trap to indicate whether or not the learning mode calibration was successful.
If the BBU skips calibration, the SCC will send an SNMP trap to indicate that the Learning Mode request is no
longer active.
The yellow LED on the SCC will stay during the Learning Mode request and while the BBU is doing the
calibration. When the BBU skips or completes learning mode, the yellow LED on the SCC will be turned off.
Using the WEB Interface
NOTE!
The SCC Controller supports a 10M Ethernet connection.
