To provide PoE with the 24-port PoE 10/100BASE-TX switching module in a
Catalyst 4006 switch, you must have a power entry module (PEM) and a power
shelf installed. The Catalyst 4006 switch can provide 312 W per PoE module to
powered devices. If the powered devices are using the maximum 15.4 W per port,
there is only enough power for 18 powered devices. If the powered devices are
using less than 15.4 W per port, more powered devices can be powered, up to the
312 W maximum. For more information about installing the PEM or the external
power shelf, refer to the Catalyst 4000 Series Installation Guide, Catalyst 4500
Series Installation Guide, Installation and Configuration Note for the Catalyst
4500 Series AC Power Shelf, or the Catalyst 4500 Series Power Entry Module and
External Power Shelf Installation Note.
To provide PoE with the 24-port PoE 10/100BASE-TX switching module in a
Catalyst 4500 series switch, you must have a PoE-enabled power supply. All
power supplies support PoE except the 1000 W and 1400 W AC power supplies.
Auto MDIX is not supported on PoE enabled switching modules.
