Time delay in PoE Management

Aruba Employee
Requirement:

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.



Solution:

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.



Configuration:

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>

 

 

Sample Configuration
(host) (config) #poe-management-profile slot 0
(host) (poe-management profile "0") #config-delay 3000



Verification

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"
