Setting Outlet Power-On Sequence and Delay
By default, outlets are sequentially powered on in the ascending order from outlet 1 to the final when turning
ON or power cycling all outlets on the Legrand PDU. You can change the order in which the outlets power
ON. This is useful when there is a specific order in which some IT equipment should be powered up first.
In addition, you can make a delay occur between two outlets that are turned on consecutively. For example,
if the power-on sequence is Outlet 1 through Outlet 8, and you want the Legrand PDU to wait for 5 seconds
before turning on Outlet 4, after Outlet 3 is turned on, assign a delay of 5 seconds to Outlet 3.
To set the outlet power-on sequence:
1. On the Outlets page, click
> Sequence Setup.
2. Select one or multiple outlets by clicking them one by one in the 'Outlet' column.
3. Click the arrow buttons to change the outlet positions.

Restores to the default sequence
Next time when power cycling the Legrand PDU, it will turn on all outlets based on the new outlet order.
The new order also applies when performing the power-on or power-cycling operation on partial outlets.
To set a power-on delay for any outlet:
1. On the same outlets list, click the 'Delay' column of the outlet that requires a wait after it is turned on.
2. Type a new value in seconds.
3. Click
Save.
Legrand PDU will insert a power-on delay between the configured outlet and the one following it during the
power-on process.
Setting Non-Critical Outlets
Outlets that are turned off when load shedding is activated are called non-critical outlets. Outlets that are not
affected by load shedding are called critical outlets. See
Load Shedding Mode
(on page 105).
Per default, all outlets are configured as critical.
To determine critical and non-critical outlets:
1. On the Outlets page, click
> Load Shedding Setup.
2. To set non-critical outlets, select the checkboxes of those you want.
