connection. In some cases, the company's inside wiring associated with a single line individual service may
be extended by means of a certified connector assembly. The customer should be aware that the compliance
with the above conditions may not prevent degradation of service in some situations.

4

PoE-80 User’s Guide

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by
the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may
give the telecommunications company cause to request the user to disconnect the equipment.

For their own protection, users should ensure that the electrical ground connections of the power utility,
telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.

Caution

Users should not attempt to make such connections themselves, but should contact the appropriate electrical
inspection authority, or electrician, as appropriate.

1 About Your PoE-80

The PoE-80 Eight-port Power over Ethernet Hub is an eight-port power injector, designed for use
with 10/100 BaseT Ethernet networks. The PoE-80 injects DC power through the unused twisted­wires (pairs 4/5 and 7/8) of a standard 8-pin CAT 5 cable. This allows increased flexibility in the
locating of power over Ethernet (PoE) enabled devices by eliminating the need for a nearby power
source.

1.1 Key Features

 Eight RJ-45, 10/100 Mbps PoE-enabled ports

 Ensures a constant power supply to PoE-enabled devices.

 Automatically detects if connected devices are PoE-enabled to avoid sending power to non-

PoE devices.

 Supports power management

 Control, status, and parameters manageable per port

 Remote power feeding up to 100 meters

 Centralized power distribution

 Protection against short circuits

 Accepts a wide range of AC power input

 Automatically updates management information.

1.2 Packaging List

The following items come with your PoE-80.

2 Hardware and Installation

Do not block the device’s rear panel fans or the side panel ventilation

holes. Leave space between devices when stacking.

2.1 Desktop Installation

Step 1. Set the PoE-80 upside-down on a sturdy level space with a power outlet nearby.

Step 2. Make sure there is enough clearance around the PoE-80 to allow air circulation and the

attachment of cables and the power cord.

Step 3. Remove the adhesive backing from the supplied rubber feet.

Step 4. Attach the rubber feet to each corner on the bottom of the PoE-80. These rubber feet help

protect the PoE-80 from shock or vibration and ensure space between devices when
stacking.

Step 5. Turn the PoE-80 right-side up after you attach the rubber feet.

2.2 Rack-mounted Installation

The PoE-80 can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other
equipment. Follow the steps below to mount your PoE-80 on a standard EIA rack using the included
rack-mounting kit.

Step 1. Align one bracket with the holes on one side of the PoE-80 and secure it with the bracket

screws. Similarly, attach the other bracket.

10

PoE-80 User’s Guide

Step 2. After attaching both mounting brackets, position the PoE-80 in the rack by lining up the

holes in the brackets with the appropriate holes on the rack. Secure the PoE-80 to the
rack with the rack’s mounting screws.

2.3 Rear Panel Connections

Connect the female end of the power cord to the power receptacle. Connect the male end to a 100­240V AC, 50-60 Hz power source (wall outlet). Push the power switch to the ON position.

11

PoE-80 User’s Guide

2.4 Front Panel Connections

The DATA OUT ports send power and data to the PoE-enabled devices. Use Ethernet cables to
connect the eight DATA OUT RJ-45 Ethernet ports to PoE-enabled devices.

Use Ethernet cables to connect the eight DATA IN RJ-45 Ethernet ports to the LAN.

The maximum Ethernet cable length is 100m.

Use a console cable to connect the console port to a management computer.

2.5 Front Panel LEDs

The LEDs give real-time information about the system’s operational status.

6 Troubleshooting

Make sure you have securely attached the proper cables to the proper ports. Refer to the Rear Panel
Connections and Front Panel Connections sections for this information. If your PoE-80 still does

not work properly, refer to the table shown next.

PROBLEM CORRECTIVE ACTION

No LEDs are on when I
turn on the PoE-80.

The PWR FWD LED is
not on or is blinking.

Check to see that the power cord is properly connected to the PoE-80
and an appropriate power source.
Make sure the power source is turned on and that the PoE-80 is
receiving sufficient power.
Contact your local distributor if the problem persists.

Check to see that the Ethernet cables are connected properly.
Contact your local distributor if the problem persists.

21

PoE-80 User’s Guide

PROBLEM CORRECTIVE ACTION

Power is not being
supplied to my PoE­enabled devices.

Ensure that the Ethernet cables connecting the PoE-enabled devices
to the PoE-80’s DATA OUT ports are securely attached. Make sure
the PoE-80 is connected to a power source.
