2.2 HPOE-460 and POE-162S, the IEEE

802.3at Injector / Splitter and Equipment

Installation

For the places hard to find the power inlet, the
HPOE-460 and IEEE 802.3at High Power over Ethernet
Splitter (POE-162S / IPOE-162S) provides the easiest
way to power your Ethernet devices such as IP Camera
on the ceiling and the Wireless Access Point installed
on the top of the building. With 4 10/100/1000Base-T
Gigabit Ethernet ports, the HPOE-460 supports full
52V DC power for any remote IEEE 802.3af / 802.3at
powered device (PD).

To control the power system of your networking devices,
the HPOE-460 can directly co-work with PoE IP phone to
build VoIP telephony network in the office. Furthermore,
the HPOE-460 can be directly connected to any third
party IEEE 802.3af / 802.3at compliant devices installed
100 meters away.

3. Troubleshooting

This chapter contains information to help you solve
issue. If the High Power over Ethernet Injector Hub
is not functioning properly, make sure the High Power
over Ethernet Injector Hub was set up according to
instructions in this manual.

How to let my Non IEEE 802.3af / 802.3at
network devices work with HPOE-460?

Solution:
You can use PLANET Power over Ethernet Splitter, such
as PLANET POE-162S / IPOE-162S to work as a power
transformer between HPOE-460 and Non IEEE 802.3af /
802.3at devices. The POE-162S and IPOE-162S provide
12V DC and 24V DC voltage output through DIP switch.

The HPOE-460 PoE LED is not light

Solution:
Check the cable connection between HPOE-460 and IEEE
802.3af / 802.3at devices.

Note

1. According to IEEE 802.3af and IEEE

802.3at standard, the HPOE-460 will not
inject power to the cable if not connect
to IEEE 802.3af and IEEE 802.3at
standard devices.

2. Due to the capability of IEEE 802.3af

and IEEE 802.3at standard, the HPOE-
460 can directly connect with any
IEEE 802.3af or IEEE 802.3at standard
compliant end-nodes.

Why can not power my PoE device on when
connect with HPOE-460?

Solution:
1. Please check the cable type of the connection from

HPOE-460 to the other end. The cable should be an
8-wire UTP, Category 5/5e/6, EIA568 cable within 100
meters. A cable with only 4-wire, short loop or over
100 meters, all will affect the power supply.

2. Please check and assure the device that fully complied

with IEEE 802.3af and IEEE 802.3at standard.

deploying the cables into your network.

Energy Saving Note of the Device

This power required device does not support Standby mode operation.
For energy saving, please remove the power cable to disconnect the device
from the power circuit.
Without removing power cable, the device wills still consuming power
from the power source. In the view of Saving the Energy and reduce the
unnecessary power consuming, it is strongly suggested to remove the
power connection for the device if this device is not intended to be active.
