Issue: PoE not providing enough power to charge the HelloDoor Surface device

Resources » FAQ » Issue: PoE not providing enough power to charge the HelloDoor Surface device

The Surface Go in HelloPorta needs 24W power in order to operate, so our Gigabit PoE+ Splitter needs to receive this.  Check if the server does not provide this, then need to install a small PoE+ switch as shown in the below image :

If the Cisco switch doesn’t deliver the PoE+ power we need, then by applying a command on the Cisco to force the Power Delivery to PoE+ for the specific port: 

SW#sh version | i IOS

Cisco IOS Software, C2960X Software (C2960X-UNIVERSALK9-M), Version 15.2(2)E7, RELEASE SOFTWARE (fc3)

 SW(config-if)#power inline ?

  auto        Automatically detect and power inline devices

  consumption  Configure the inline device consumption

  never        Never apply inline power

  police      Police the power drawn on the port

  port        Configure Port Power Level

  static      High priority inline power interface

SW(config-if)#power inline consumption ?

  <4000-30000>  milli-watts

 SW(config-if)#power inline static ?

  max  Maximum power allowed on this interface


 SW(config-if)#power inline static max ?

  <4000-30000>  milli-watts

 In general, the static value is configured to maximum value and it is permanent (But it can fail if the Switch doesn’t have enough energy), In this case, not exist analyzing of consumption by hours, days, etc. This configured has high priority

 About the consumption value, it is configured based in an estimation (because the CDP protocol can do an automatic adjustment), for that reason it is optional and it doesn’t have high priority.
