1 About This Guide

This guide provides all the information you need to install and use the
Ethernet PowerHub unit with default settings.

The guide is intended for network administrators responsible for installing
and setting up network equipment; consequently, it assumes a basic
working knowledge of LANs (Local Area Networks).

Introducing the Ethernet PowerHub

2 Introducing the Ethernet

PowerHub

This chapter contains introductory information about the PowerHub and
how it can be used in your network.

By connecting the PowerHub to a UPS (Uninterruptible Power Supply),
the PowerHub provides a cost-effective way to distribute back-up power
for Ethernet terminals. This capability increases IP telephony service
reliability by ensuring that IP phones keep working in the event of a
power failure.

In addition to greater network availability, the PowerHub reduces
installation and maintenance costs by eliminating the need for the
installation of additional power outlets. This is particularly true in hard-to­reach places such as ceilings, where other IP devices such as wireless
access points or Web cameras are normally located.

The PowerHub sits in tandem to an existing Ethernet or Fast Ethernet
and connects via standard CAT 5 cabling. This architecture also serves
to protect customers´ investments in both CAT 5 infrastructure and in
Ethernet switch equipment.

By sending 24V DC over 100 meters, Ethernet terminals, including IP
phones, wireless LAN access points and Web-cameras can utilize power
provided from the PowerHub.

Features

3 Features

Advanced Auto-Sensing Algorithm – The Ericsson PowerHub 4012
features a unique load auto-sensing algorithm that automatically detects
Power-over-Ethernet compatible terminals and supplies inline power. The
per-port, sophisticated power control and monitoring circuit enables fast
installation while ensuring continuous proper operation of devices such
as ordinary Network Interface Cards (NIC) that do not expect power on
their Ethernet connection.

Y Easy to Use - The PowerHub is a plug-and-play product. Once

turned on, it will automaticall y detect all Po wer- o ver- Et hernet
compatible terminals and supply inline power immediately. All port
interfaces are located on the front panel providing easy access.

Y Compact size – The standard 19”, 1.5U high PowerHub allows easy

rack mounting while consuming minimal space in the wiring closet.

Y Concise LED displays – The PowerHub provides real-time network

monitoring through the front panel, including two LED per port
indicating normal and overload or short circuit conditions
respectively. Additional LED indicators are included for main power
supply and internal self-test monitoring.

Y Wide Range AC Input - The PowerHub Power-over-Ethernet hub

supports a wide range of AC input voltages at 100-240V AC and DC
voltages at 24V DC.

Y Standard Compliance – The PowerHub is fully compatible with the

802.3 standard when no inline is supplied. The 802.3 standard does
not include specification for providing power over the Ethernet.
