Key Benefits

Distribute data

and power across

the network using

your existing

LAN cabling

Power over Ethernet

Powers up to 24 data connections for

network jacks, wireless LAN access

points, IP phones, and other Power

over Ethernet-compatible networked

devices—over your existing network

infrastructure.

Cost Savings

Centrally distributed power helps

lower operating costs and eliminates a

clutter of local power hardware,

cords, and battery backups.

Easy Installation

No new wiring for power required.

Midspan solution introduces power to

connections coming from the switch,

preserving investments in existing

data equipment and Ethernet wiring.

Reliable Power

Combining an uninterruptible power

supply (UPS) and midspan solution in

the wiring closet helps ensure contin-

uous availability of IP phones and

wireless LAN access points during

power failures.

Scalable Solution

24-port solution powers a variety of

Ethernet infrastructures and devices.

Multiple power sources can be config-

ured to support additional devices.

IEEE P802.3af compliant

Fully compliant with the IEEE

P802.3af draft specification, to help

ensure interoperability with a wide

range of Ethernet technologies and

hardware.

Safe Power Source

Resistive power discovery automati-

cally detects power-compatible devices.

Power is witheld from legacy, nonstan-

dard, and unpowered devices—for

maximum flexibility and safety.

Backwards Compatible

3Com

NBX

Phone Power Module

enables a 3Com NBX phone to receive

Power over Ethernet from any

P802.3af-compliant power source,

including 3Com Network Jacks.

The 3Com Power over Ethernet

Multiport Midspan Solution powers

network jacks, NBX telephones, Wi-Fi

access points, and other Power over

Ethernet-compatible devices using

standard Ethernet cabling. Installing

this 24-port midspan power source in

a secure wiring closet or other cen-

tralized location gives administrators
