PoE on 48 Port Switch

WashburnIT

I need to replace some old PoE Switches.  I'm looking at the Cisco Catalyst 2960X-48LPS-L, 48-Port Gigabit Power over Ethernet Switch.  In it's documentation it states a total of 370W.  It then states, "Maximum Number of PoE (IEEE 802.3af) Ports" is "24 ports up to 15.4W".

It also says " Intelligent power management allows flexible power allocation across all ports."

Does the intelligent power management statement mean that I can put power out every port, or am I limited to only sending power on 24 ports at a time?

We need the PoE for IP Phones, and each line only needs 7.4W.  If I were to use each of the 48-Ports with 7.4W, I'd still be under the 370W power limit.

Can I use all 48-Ports with setting the power inline consumption, or am I limited to only being able to use 24 PoE ports at a time?

Thanks in advance!

It means you are allowed 370w of PoE power.  You can have a mix of 7.7w PoE or 15.4w PoE as long as you don't exceed 370w PoE power available.
