powered ports in a rack, the maximum capacity would not reach 240 x 15.4W = 3696W due to power supply and heat dissipation problems. To better manage actual power as opposed to standard maximum power, Cisco came up with intelligent power management features.
For example, the Catalyst 4500/6500 series switch has three PoE modes:
∙Auto PoE interface. The supervisor engine directs the switching module to power up the interface only if the switching module discovers the PD and the switch has enough power. You can specify the maximum wattage that is allowed on the interface. If you do not specify the wattage, then the switch will deliver no more than the
∙Static - High priority PoE interface. The supervisor engine
∙Never - Data interface only. The supervisor engine never powers up the interface, even if an unpowered phone is connected. This mode is only needed when you want to make sure power is never applied to a
To properly operate
∙Use Static mode and allocate 10,000 mW of power per
Or
∙Use Auto mode with same setting (10,000 mW).
If you get an error doing this operation – you need to check your PoE limitations (refer to the product manual for additional information).
