Cisco launched a new version of PoE called ePoE or “enhanced” power over ethernet. What’s this? Confusing marketing at its finest? Let’s find out…
This new version of PoE is only available in the Catalyst 3750-E and 3560-E Series switches, with ePoE availability for Cisco’s Catalyst 6500 and Catalyst 4500-E Series devices scheduled to follow in the second quarter of this year.
One of the reasons for this new type of PoE is because of 802.11n wireless AP’s. These APs use a lot of power – more power than older APs. This was causing customers to have to supply two PoE cables to every 802.11n wireless AP. With the new ePoE, they don’t have to do that.
The cool thing is that you can just upgrade the IOS of your supported switch and get the new ePoE update. The downside is that ePoE is proprietary so you must use Cisco 802.11n wireless APs to take advantage of this new feature. You can read more about ePoE at Cisco’s website.
