47Metered Rack PDU User’s Guide
Device Management
About the Device Manager Tab
Path: Device Manager
Use the Device Manager tab:
• View the load status for the Rack PDU
• Configure load thresholds for the device, phases, and banks as applicable
• Configure a name and location for the Rack PDU.
• View and manage the peak load measurement
Viewing the Load Status and Peak Load
Path: Device Manager > Load Management options
Use the Load Management menu options to view the load for the device, phases, and banks. The
indicator in the green, yellow, and red meter shows the current load status: normal, near overload, or
overload. If a low load threshold was configured, the meter will include a blue segment to the left of the
green. When viewing the Device Load, the triangle above the meter indicates peak load.
Configuring Load Thresholds
Path: Device Manager > Load Management options
Note: The Rack PDU generates an alarm when any bank exceeds its rated value. However, if
a circuit breaker trips, there is no definitive indication that the circuit breaker is open, other
than that the current for that bank will drop. Set the Low Load Warning Threshold to
1 Amps for these reasons:
• The default setting for the Low Load Warning Threshold is 0 Amps. This effectively disables
the warning. With a setting of 0 Amps for the Low Load Warning Threshold, the Web interface
will not indicate that a circuit breaker may have tripped.
• A 1-Amp detection threshold for the Low Load Warning for Bank Load Management will help to
indicate that a circuit breaker may have tripped.
To configure load thresholds:
1. Click the Device Manager tab.
2. Using the Load Management menu, set the thresholds for the device, phases, and banks. The
configurable thresholds are Overload Alarm, Near Overload Warning, and Low Load
Warning for the device, phases, and banks.
3. Click Apply.
