802.3af modular installed base considerations
802.3af minimum PSE voltage: 44V
Modular switches
– 44V power supply is deployed with chassis
– Customer expectation: 802.3at-blades added to 802.3af-chassis
– 51V minimum at PSE
Æ Boost converter MUST be placed on blade
More power dissipation at blade
More components added to crowded blade
