Functions and Features
The High-Power Gigabit single port PoE (Power over Ethernet)
PD-9501G/24AC Midspan injects power over data-carrying Ethernet cabling. It
maintains the IEEE802.3at draft 3.2 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 Transmitters, PTZ Cameras & more. The PD-9501G/24AC "DATA &
POWER OUT" port is designed to carry Gigabit Ethernet data & power over a
standard CAT5e cable, delivered through all 4-pairs
(Alt A: pins 1,2 (-) & 3,6 (+), Alt B: 4,5 (+) and 7,8 (-)).
EMC Compliance

Preliminary Steps
•
Ensure
24
VAC power is applied to the PoE Midspan, using cables of 12
AWG for each terminal or 2X16 AWG for each terminal
(rated for 6
Amperes)
, with an appropriate separate ground connection (when
needed).
•
Ensure
output Ethernet cable is connected to the
"DATA & POWER OUT" port.
•
Verify that power ready Ethernet compatible device is connected.
WARNING
Do not use cross over cable between the PoE Midspan output port
and the load device
Installation
The PoE Midspan may be located on a desktop or wall/bench mounted using the
rear side mounting holes.
•
Associated Ethernet wiring shall be limited to inside of the building
•
The power inlet cable and chassis connection cable is not supplied with the
product
:
Before mounting the PoE Midspan to a fixed location:
•
Do not to cover PoE Midspan or block the airflow to the PoE with any foreign
objects. Keep the PoE Midspan away from excessive heat and humidity and
free from vibration and dust.
•
Ensure that the cable length from Ethernet network source to the terminal
does not exceed 100 meters (333 Feet). The PoE is not a repeater and does
not amplify the Ethernet data signal.
•
Use a splitter if desired; ensure that the splitter is connected close to the
terminal and
not
on the Midspan!
•
No “on-off” switch exists; simply plug the PoE Midspan into a
24
VAC power
source.
Installing the Unit
•
Verify the
24
VAC power source is turned off.
•
If the supplemental earth ground is replaced, apply 5Lb/In torque.
(Optional)
•
Tighten the 2 connector screws (See Figure 2).
•
Connect the PoE Midspan Input connector to cables of Stranded Tinned
Copper, 12 AWG for each terminal or 2X16 AWG for each terminal
(rated for 6 Amperes) and tighten the 2 Cable inlet screws
(See Figure 2).
:
The polarity of the input connection is not important.
•
Connect the "DATA IN" jack (input) to the remote Ethernet network
switch's Patch panel and the "DATA & POWER OUT" jack (output) to
the terminal (See Figure 3).
•
Turn on the
24
VAC power source and verify appropriate leds indication.

Troubleshooting
Symptom
Corrective Steps
PoE Midspan
does not
power up
1. Ensure
that
the
installation was
according to "Installing the Unit" section
in this user guide.
2. Ensure that the power source voltage is
between 22-28VAC 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 Powered
Device (PD)
does not
operate
1. Verify that the PD is designed for PoE
operation according to IEEE802.3af/at
standard.
2. Verify that you are using a standard
straight-wired four Pairs cable
(UTP/FTP Category 5/5e/6).
3. Verify that the PD is connected to the
PoE Midspan "DATA & POWER OUT"
port.
4. If an external power splitter is in use,
replace it with a known-good splitter.
5. Remove and re-apply power to the PoE
Midspan, and check the led indicators
during power up sequence.
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
straight-wired four Pairs cable
(UTP/FTP Category 5/5e/6).
3. Verify that the Ethernet cable length is
less than 100 meters from Ethernet
source to load/remote terminal.
4. Ensure that the input Ethernet cable is
connected to the PoE Midspan "DATA
IN" port.
5. If an external power splitter is in use,
replace it with a known-good splitter.
