The EPS can provide a maximum of up to 900 watts of PoE power to each of the two EPS ports depending on which power supply is used. It is important to understand the PoE power requirements of the 5400zl Series switches because if the PoE power is not planned and implemented correctly the end devices connected to the switch ports may not receive power if an internal switch PoE power supply should fail. For further information regarding the Power Supply Shelf PoE capabilities, see the ProCurve Power over Ethernet (PoE) for zl and yl Products Planning and Implementation Guide and the ProCurve Power Supply Shelf Installation and Getting Started Guide, which is on the ProCurve Web site. See page 5-1 for details. Power Supply Shelf LEDs The EPS LEDs are duplicated on the front and back of the device. The following graphic shows an example of the front of the EPS.
