PDU-level outlet initialization delay on startup: See
Options for Outlet State on Startup
Options for Outlet State on Startup
The following are available options for initial power states of outlets after powering up the PDU.
Option
Function
on
Turns on the outlet(s).
off
Turns off the outlet(s).
last known
Restores the outlet(s) to the previous power state(s) before the PDU was powered off.
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.
How the Automatic Management Function Works
After enabling the automatic management function:
When the total number of managed sensors and dry contacts has not reached the upper limit yet, the PDU automatically
brings newly connected environmental sensors and dry contacts under management after detecting them.
A PDU can manage up to 32 sensors/dry contacts.
After disabling the automatic management function:
The PDU no longer automatically manages any newly added environmental sensors and dry contacts, and therefore
neither ID numbers are assigned nor sensor readings or states are available for newly added ones.
You must manually manage new sensors/dry contacts. See
Time Units
If you choose to type a new value in the time-related fields, such as the Inrush Guard Delay field, you must add a time unit
after the numeric value. For example, you can type '15 s' for 15 seconds.
Note that different fields have different range of valid values.
