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
<cr>
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.
