INTRODUCTION
Overview
The SCC (System Control Card) controller is accessed via SNMP/V2.
The SCC Controller performs the following functions.
•SNMP/V2 communication to an RMS (Rack Management System). This communication interface can
be used to monitor, configure, and control rectifiers and BBU’s (Battery Backup Unit).
•Rectifier Module and BBU Module Control
•Imminent Power Failure Notification
•EPO (Emergency Power Off)
•Current Limit Management of Rectifiers
•Rectifier Intelligent Power Matching (Energy Optimization Mode)
•Rectifier and BBU Module Data Monitoring
•Alarm Detection and Reporting
Function Descriptions
SNMP Communication to an RMS, including Rectifier and BBU Module Configuration via SNMP/V2
See “SCC Controller Interaction with the RMS” on page 12.
Rectifier Module and BBU Module Control
Rectifier and BBU modules are automatically controlled by the SCC Controller.
Imminent Power Failure Notification
The imminent power fail signal triggers >1 ms before the DC bus collapses. It triggers when the combination of
rectifiers and batteries on the bus can no longer support the load.
•Rectifiers cannot provide enough power for the load.
•Batteries cannot make up the difference.
This signal identifies the loss of the output DC bus prior to the loss of regulation in these situations:
•The AC main stops providing power and battery backup is not available.
•The AC main stops providing power; the batteries provided backup power but the batteries are nearly
discharged.
•All rectifiers are needed to support the DC bus and one rectifier fails, and battery backup is not available.
EPO (Emergency Power Off)
Systems utilizing the Emergency Power Off (EPO) feature will have provisions to connect a customer provided
EPO switch. The EPO switch is normally open, when closed a signal is sent to shut down the rectifier and BBU
modules.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 BBU’s.

Vertiv |NetSure™ SCC Controller User Manual (UM1M520HNA)|Rev. H
10
Current Limit Management of Rectifiers
The amount of total AC power that the rectifiers are using can be limited by the RMS. The rectifier total DC
current limit parameter specifies the total DC current limit for all of the rectifiers combined. If the load needs
more than the rectifiers can provide with this limit, the BBU modules will make up the difference.
Rectifier Intelligent Power Matching (Energy Optimization Mode)
The SCC Controller provides an Energy Optimization Mode function. Energy Optimization permits an
installation to only operate rectifiers as needed to maintain the load. As load increases, Energy Optimization
turns on additional rectifiers as needed to maintain the load. As load decreases, Energy Optimization places
rectifiers in standby to conserve energy usage. Rectifiers which are always operating to maintain any load
requirements are cycled through the group of rectifiers controlled by this feature to provide uniform operating
times for each rectifier.
Rectifier and BBU Module Data Monitoring
The SCC Controller monitors the components comprising the system (such as the rectifier modules) and
generates alarms if a fault condition occurs.
These are accessed via the SNMP/V2 interface. See “SCC Controller Interaction with the RMS” on page 12.
Alarm Detection and Reporting
The SCC Controller reports alarm conditions via SNMP traps over Ethernet. The SCC Controller acquires and
analyses real time data from the system’s components such as the rectifier modules. The SCC Controller uses
this data to process alarms. The SCC Controller also maintains an alarm history log.
These are accessed via the SNMP/V2 interface. See “SCC Controller Interaction with the RMS” on page 12.
Alarm Logs
The alarm logs can be viewed using the Web Interface or via SNMP and consist of...
•Alarm History Log: Log of most recent alarms.
•Active Alarm Log: Log of active alarms.
NOTE! Once maximum number of log entries is reached, new entries overwrite oldest entries.

OPERATION
NOTE! Refer to the Configuration Drawing (C-drawing) furnished with your system for a list of factory
default settings.
SNMP Access
Users can access the SCC Controller via SNMP through the Ethernet Port. It is beyond the scope of this
manual to describe SNMP interface operation. Refer to the SNMP MIB file for a further understanding of the
SNMP interface.
Operation of the SCC Controller requires a master upstream supervisory and control unit, such as the Avocent
UMG, connected to the system’s Ethernet port and utilizing an SNMP interface.
NOTE! The rectifier and BBU modules will continue to operate if the SCC Controller fails. The rectifier
and BBU modules will work if the system is powered up without an SCC Controller; however, an SCC
Controller is required to get any monitoring/status information from the system. The application should
be designed with an SCC Controller.

SNMP Traps From the SCC Controller to the RMS
SNMP traps are unsolicited messages sent from the SCC Controller to the RMS.
These are the alarms the SCC Controller provides to the RMS.
There are two sets of traps; the set that is sent by the SCC is determined by “configTrapTimeFormat.The only
difference between the two sets of traps is the format of the date/time field. One set uses a human-readable
date/time format as a text string; the second set uses the DateAndTime format.

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.
