If you are configuring an individual outlet on
Individual Outlet Pages
(on
page 165), there is one more outlet state option.
Additional
option Function
PDU defined
(xxx) Follows the global outlet state setting, which is set
on
PDU (on page 145).
The value xxx in parentheses is the
currently-selected global option - on, off, or last
known.
Initialization Delay Use Cases
Apply the initialization delay in either of the following scenarios.

When power may not initially be stable after being restored

When UPS batteries may be charging
Tip:
When there are a large number of outlets, set the value to a lower
number so that you can avoid a long wait before all outlets are available.
Inrush Current and Inrush Guard Delay
Inrush current:
When electrical devices are turned on, they can initially draw a very large
current known as inrush current. Inrush current typically lasts for 20-40
milliseconds.
Inrush guard delay:
The inrush guard delay feature helps prevent a circuit breaker trip due to
the combined inrush current of many devices turned on at the same
time.
For example, if the inrush guard delay is set to 100 milliseconds and two
or more outlets are turned on at the same time, the PDU will
sequentially turn the outlets on with a 100 millisecond delay occurring
between each one.
