WS-X4248-RJ21V

The WS-X4248-RJ21V 48-port IEEE 802.3af-compliant PoE 10/100BASE-TX

RJ-21 switching module (see Figure 1-21) has the following specifications:

Figure 1-21 WS-X4248-RJ21V IEEE 802.3af-Compliant PoE 48-Port 10/100-Mbps Switching Module

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
