Functions and Features
The high-power gigabit single port PoE (Power over Ethernet)
PD-9501G/48VDC Midspan injects power over data-carrying Ethernet
cabling. It maintains the IEEE802.3at and IEEE802.3af standard, while
doubling the output power (60W). These power levels allow usage by a
new range of Ethernet-based applications such as Video Phones, 802.11n
access Points, WiMAX
TM
Transmitters, PTZ Cameras & more. The
PD-9501G/48VDC
"DATA & POWER OUT"
port is designed to carry
Gigabit Ethernet data & power over a standard CAT5/5e/6 cable, delivered
through all 4-pairs

Preliminary Steps
•
Ensure
DC
power is applied to the PoE Midspan, using stranded tinned
copper 16 AWG cables for each terminal (rated for 2 Amperes), with an
appropriate separate ground connection (when needed).
•
Ensure that the output Ethernet cable is connected to the
"DATA &
POWER OUT"
port.
•
Verify that an Ethernet compatible device is connected to the output
Ethernet cable, and that it is arranged to receive power on its Ethernet
port.
WARNING
Do not use a cross over cable between the PoE Midspan output port and the
load device.
Installation
The PoE Midspan may be located on a desktop/ floor or mounted on a
wall/bench using the rear side mounting holes.
•
Associated Ethernet wiring shall be limited to inside of the building
•
Power inlet cable and chassis connection cable are not supplied with the
product
:
Before mounting the PoE Midspan to a fixed location:
•
Make sure the PoE Midspan and the airflow to it, are not covered or
blocked by any foreign objects. Keep the PoE Midspan away from
excessive heat and humidity and ensure it is free from vibration and
dust.
•
Ensure that the total Ethernet cable length does not exceed 100 meters
(333 feet). The PoE is not a repeater and does not amplify the Ethernet
data signal.
•
A splitter may be used if desired; ensure that the splitter is connected
close to the PD but not to the Midspan.
•
There is no “On-Off” switch; simply plug the PoE Midspan into a
DC
power source.
Installing the Unit
•
Verify that
DC
power source is off.
•
If supplemental earth ground is replaced, apply 5Lb/In torque (optional).
•
Tighten the 2 connector screws (see Figure 2).
•
Connect the PoE Midspan PWR connector to stranded tinned copper
cables, 16 AWG for each terminal (rated for 2 Amperes), and tighten the
2 Cable inlet screws (See Figure 2).
•
Connect the “DATA IN” jack (input) to the data source (switch) and the
“DATA & POWER” jack (output) to the terminal (PD) (See Figure 3).
•
Turn on the
DC
power source and check the appropriate LED indicators
to verify that power is on

Troubleshooting
Symptom
Corrective Steps
PoE Midspan
does not
power up
1. Ensure that the installation was in
accordance with the "Installing the
Unit" section in this user guide.
2. Ensure that the power source
supplies between 36-60VDC and can
carry out 80W.
3. Remove and re-apply power to the
PoE Midspan, and verify that the main
led indicator on the front panel is
continuously lit.
The PD
(Powered
Device)
does not
operate
1. Check the Midspan’s LED indicators.
2. Remove and re-apply power to the
PoE Midspan, and check the led
indicators during power up sequence.
3. Verify that the PD is designed for PoE
operation.
4. Verify that you are using a standard
UTP/FTP category 5/5e/6, straight-
wired four pairs cable.
5. Verify that the PD is connected to the
"DATA & POWER OUT" port.
6. If an external power splitter is in use,
replace it with a splitter known as
good.
The end device
operates,
but there is
no data link
1. Verify that the port LED indicator on
the front panel is continuously lit.
2. Verify that you are using a standard
UTP/FTP Category 5/5e/6, straight-
wired cable.
3. Verify that the Ethernet cable length is
less than 100 meters from the POE
source to PD.
4. Ensure that the input Ethernet cable
is connected to the "DATA IN" port.
5. If a splitter is in use, replace it with a
splitter known as good.
