Cisco Enhanced Power Over Ethernet for 802.11ac support

[briansciarra]

Hello,

We are quoting equipment for a new site.

The 2602 AP's we normally get have been replaced the the 2702.

The 2702 supports 802.11ac, but only when a POE switchport is providing 20w power.

Our 2960 switches (WS-C2960+48PST-L) running at 15.4w per switchport.

I read about Cisco Enhanced Power Over Ethernet, where you can modify the wattage to run at 20w.

My question is does the model switch referenced above support Cisco Enhanced Power Over Ethernet?

Hi brian,

Looking at the datasheet, the 2960+ series don't appear to support 802.11at/PoE+ at all and max out at 15.4W

Table 2. Switch PoE Power Capacity

Switch Model	Maximum Number of PoE (IEEE 802.3af) Ports*	Available PoE Power
Cisco Catalyst 2960-Plus 48PST-L	24 ports up to 15.4W	370W
Cisco Catalyst 2960-Plus 24PC-L	24 ports up to 15.4W	370W
Cisco Catalyst 2960-Plus 24LC-L	8 ports up to 15.4W	123W
Cisco Catalyst 2960-Plus 48PST-S	24 ports up to 15.4W	370W
Cisco Catalyst 2960-Plus 24PC-S	24 ports up to 15.4W	370W
Cisco Catalyst 2960-Plus 24LC-S	8 ports up to 15.4W	123W

Also theCisco Enhanced PoE technology is only available on a select few switches which don't include the 2960+ series according to this:

If you are reluctant to replace your switches then you can purchase 'midspan' devices which provide the necessary power through a power injector. These come in single 'brick' styles (lookup Cisco AIR-PWRINJ4) or in switch-like multiple Access Point midspan PoE devices.

Note - These devices only provide power and no other functionality.
