I do know that the current ESW 500 switch models do not have enough capacity to power all of the switchports at 15.4W, even though the ESW-540-8P model has almost enough capacity to power all of the switchports at 15.4W.
Reasons why new ESW 500 switches with increased PoE capacity are needed:
The existing ESW 500 PoE switches do not always have enough capacity when these devices are deployed with the UC500:
7945, 7965, and 797x phones
8900 and 9900 series phones (not yet supported with the SBCS solution)
PVC2300 Surveillance cameras
AP541N access points
The UC560 does not ship with any PoE ports and requires at least one ESW switch be deployed
The 48-port gigabit version of the ESW switch is currently available only in a non-PoE version, and there is a need for a 48-port gigabit version for users deploying the UC560 solution.
The PoE capacities of the existing ESW 500 switches are:
The PoE capacities of ESW 500 switches supporting the full 15.4W PoE power on all PoE ports are:
Are there plans to release new ESW 500 switch models with increased PoE capacity, enough to deliver the full 15.4W to all of the PoE ports?
