In some situation we might need some time delay while applying the PoE configuration between each port on the Aruba Mobility Access Switch. The requirement of time de;ay will be in order to avoid POE module to spike up or burst when we turn on all the POE devices which got connected to the Switch.
Starting from ArubaOS 7.3.2, the Mobility Access Switch allows you to configure a time delay while applying the PoE configuration between each port. For example, if you configure a delay of 2 seconds and if the PoE configuration is applied on port 0 at t seconds, then the PoE configuration is applied on port 1 at t+2 seconds, port 2 at t+4 seconds and so on. A new CLI command, config-delay is introduced under the PoE management
profile to configure the delay time in milli seconds. The allowed range is between 0 to 30000ms in steps of 100ms. The default value is 2000 ms.
Configuring Delay Time
Execute the following commands to configure the delay time for applying the PoE configuration between ports:
(host) (config) #poe-management-profile slot <0-7>
(host) (poe-management profile "<0-7>") #config-delay <config-delay>
(host) (config) #poe-management-profile slot 0
(host) (poe-management profile "0") #config-delay 3000
Verifying Delay Configuration
Execute the following command to verify the configured delay time for applying the PoE configuration between ports:
(host) #show poe-management-profile slot 0
poe-management profile "0"
