* Note that calculations for heat dissipation is based on one power supply operating at maximum output power.
** Measured when two AC power shelves are strapped together and contain 3x2500W AC power supplies.
*** Measured when using Cisco prestandard PoE line cards (WS-X4148-RJ45V).
Additional notes for Table 7 and 8:
1. Output power is per power supply, unless otherwise stated.
2. Heat dissipation numbers represent the power-conversion losses of the power supply in operation.
3. The number of power devices supported will depend on customer configuration.
