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 smaller
number to 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.
Z Coordinate Format
Z coordinates refer to vertical locations of Raritan's environmental sensor
packages. You can use either the number of rack units or a descriptive text to
describe Z coordinates.
For a Z coordinate example, see
