To provide PoE with the 48-port PoE 10/100BASE-TX switching module in a
Catalyst 4006 switch, you must have a power entry module (PEM) and 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
