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.

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.

Installing the PowerHub

6.1 Choosing a Suitable Site

The PowerHub is suited for use in an office environment where it can be
mounted in a standard 19-inch equipment rack, or free standing.
Alternatively, the PowerHub can be rack-mounted in a wiring closet or
equipment room. In order to supply back-up power to the Ethernet
terminal a UPS (Uninterruptible Power Supply) should be available,
where the PowerHub is installed.

When deciding where to position the PowerHub, ensure that:

Y You are able to meet the configuration rules for Fast Ethernet
Y The PowerHub is accessible and cables can be connected easily.

Cabling is away from:
Y Sources of electrical noise such as radios, transmitters and

broadband amplifiers

Y Power lines and fluorescent lighting fixtures
Y Water or moisture cannot enter the case of the PowerHub.
Y Airflow is not restr icted ar o und the Po wer Hub or throu gh the vents in

the side of the PowerHub. We recommend that you provide a
minimum of 25 mm (1in.) clearance.

Y In a free-standing configuration no more than four PowerHub units

should be placed on top of each other.

6.2 Mounting the PowerHub

6.2.1 Rack Mounting

The PowerHub is 1.5U high and fits in most standard 19-inch racks.

''''

CAUTION! Prior to mounting, disconnect all cables from the PowerHub



before continuing.
Remove all self-adhesive rubber feet from the underside of the PowerHub
if they have been fitted.

1. Place the PowerHub right side up on a hard flat surface, with the front
facing towards you.

9

Installing the PowerHub

2. Locate a mounting bracket over the mounting holes on one side of the
PowerHub, as shown in the figure over leaf.

3. Insert the three screws and tighten with a suitable screwdriver.

Fitting a bracket for rack mounting.

''''

NOTE: You must use the screws supplied with the mounting brackets.



Damage caused to the unit by using incorrect screws invalidates your
warranty.

4. Repeat steps 2 and 3 for the other side of the PowerHub.

5. Insert the PowerHub into the 19-inch rack and secure it to the rack
with suitable screws (not provided). Ensure that ventilation holes are
not obstructed.

6.2.2 Shelf Mounting

When shelf mounting the PowerHub, the self-adhesive rubber feet
provided in the kit should be placed on the underside of the PowerHub.
Be sure to place the rubber feet on the provided 90° angle marking in
order to assure stable placement.

No more than 5 PowerHubs are to be placed on top of one another if the
units are shelf mounted.

10

Installing the PowerHub

6.3 Connecting the Hub to the Ethernet
Network

The PowerHub is installed in tandem with an Ethernet switch or Ethernet
hub. Twisted pair cables (from the Ethernet switch or Ethernet hubs) are
connected to the lower row of the RJ45 connectors (Data In) on the
PowerHub. Twisted pair cables from the upper row of RJ45 connectors
(Data & Power Out) are connected to the patch panel, from where the
Ethernet wiring goes out into the building.

The PowerHub automatically adds power, only when a terminal
connected to a socket is Power-over-Ethernet enabled.

The twisted pair cable connecting the PowerHub with the Ethernet switch
or Ethernet hub should be selected so that it is as short as possible
(since it is a part of the 100m maximum cable according to the
IEEE802.3).

By connecting port one on the Ethernet to port one on the PowerHub
etc., the installation is easier to maintain.

6.4 Connecting a Terminal to the PowerHub

- Example

Only a twisted pair cable is needed when a Power-over-Ethernet ready
terminal is connected to the PowerHub.

It is also possible to supply power to Ethernet terminals that were not
originally designed for Power-over-Ethernet, such as the Ericsson Dialog
3413 IP Phone. In this case a passive splitter is needed. The passive
splitter physically splits the data pairs and the power pairs in the twisted
pair cable.

6.5 Connecting the PowerHub to AC and
Power-up

The following sections describe how to get your PowerHub powered-up
and ready for operation.

6.5.1 Powering-up the PowerHub

Use the following sequence of steps to power-up the PowerHub.

''''

CAUTION: The PowerHub has no ON/OFF switch; the only method of



connecting or disconnecting main power is by connecting or disconnecting
the power cord.

11

Installing the PowerHub

1. Plug the power cord into the power socket at the rear of the
PowerHub.

2. Plug the other end of the power cord into your power outlet or UPS

The PowerHub powers-up and runs through its Power On Self-Test
(POST), which takes approximately 10 seconds.

6.5.2 Checking for Correct Operation

During the Power On Self-Test, all ports on the PowerHub are disabled
and the LEDs light in the following sequence:

Y All unit LEDs light green & orange for 2 sec.
Y All unit LEDs off for 2 se c.
Y AC power LED is continually lit
Y All ports LED are ready for normal indications
