Rack PDU is nearing overload of a phase or bank.

Low Load Warning

Prevent users from applying power to outlets during an overload

condition. You can set the following restrictions for each outlet:

• None: You can apply power to outlets regardless of an Overload

Alarm or Near Overload Warning.

• On Warning: You cannot apply power to an outlet on the

selected phase or bank if the current for that phase or bank has

exceeded the Near Overload Warning threshold.

• On Overload: You cannot apply power to an outlet on the

selected phase or bank if the current for that phase or bank has

exceeded the Overload Alarm threshold.

Coldstart Delay The time that the Switched Rack PDU delays applying power to

the outlets after AC power has been applied to the Rack PDU.
