Metered Rack PDU

Setting the Low Load Warning Threshold

• 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 2-Amp detection threshold will help to indicate that a circuit breaker may have

tripped.

Web interface.

1. Select the Device Manager tab, or click More in the Load Status section of the

Home page.

2. Set the Low Load Warning Threshold for each bank or phase to 2 Amps.

3. Click Apply in each bank or phase section to set the selected values.

Note

With factory default settings, the Rack PDU generates a warning

alarm when any bank exceeds 16 Amps, and generates a critical

alarm when any bank exceeds 20 Amps. 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 2 Amps for these

reasons:
