Microsemi 9501G/48VDC User Manual

Safety Information

Important Safety Information

♦ Install ation and removal of the PoE Midspan must be

carried out only by qualified personnel.

♦ Only an isol ated AC/DC power source should be used

to power up the POE Midspan.

♦ The external power supply for t he equipment will be a

listed, direct plug in power unit, marked Class 2, or
listed ITE power supply, marked LPS, which has
suitably rated output voltage and current.

♦ DC Power Inlet:

 The power connector supplied with the PoE Midspan

(included in the package) has 2 terminals; '+' (POS)
and '-' (NEG) (See Figure 2).

 The power inlet cables (not included in the package)

must be rated for current capacity of 2 Amperes
(Stranded

tinned copper 16 AWG for each terminal).

 Before connecting power inlet cables t o the connector

terminals verify that the power source is off.

 After inserting a cable inlet to the connector terminals,

tightly fasten all 4 connector screws (See Figure 2).

 This clause is optional:

For improved EMI performance, connect chassis
ground connection to "Earth/Ground" connection at

the working area.
There is no safety hazard when the chassis ground
connection is not connected to the "Earth/Ground".

The PoE Midspan "DATA IN" and "DATA & POWER OUT"
ports are shielded RJ45 data sockets. They cannot be used
to connect telephone wiring. Only RJ45 data connectors
can be connected to these sockets.

The DC power source should be situated near the PoE
Midspan and easily accessible. To disconnect the power
from the PoE Midspan, disconnect the DC power cord from
either the DC power source or from the PoE Midspan power
connector.

The PoE Midspan “DATA IN” and “DATA & POWER OUT”
interfaces are qualified as SELV (Safety Extra-Low Voltage)
circuits according to IEC 60950-1. These interfaces can be
connected only to SELV interfaces of other equipment.

WARNINGS:

• Before connecting the PoE Midspan to its power source,
read the installation instructions.

• Whenever connecting the PoE Midspan to its power source,
follow basic electricity safety measures.

• A voltage mismatch can cause equipment damage and may
pose a fire hazard. If the voltage indicated on the label is
different from the power outlet voltage, do not connect the
PoE Midspan to this power outlet.

• Take extra care when connecting the power inlet
terminals, so that '+’ (POS) and '-' (NEG) terminals are

connected to the proper polarity.

Mounting Instructions

Perform the following instructions:

1. Install two screws in the wall or shelf as shown in Figure 1.

Figure 1: PoE Midspan mounting instructions

2. Align the PD-9501G/48VDC mounting slots to capture the surface
screws.

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 p ower (60W). These power lev els allow usage by a
new range of Ethernet-based applicati ons such as Video P hones, 80 2.11n
access Points, WiMAX

TM

Transmitters, PTZ Cameras & more. The
PD-9501G/48VDC "DATA & POWER OUT" port is designed to carry
Gigabit Ethernet dat a & pow er over a stan dard CA T5/5e/6 cable, delive red
through all 4-pairs

EMC Compliance:

• FCC Part 15 class B

• EN55022 class B

• EN55024

Safety compliance:

♦ UL60950-1
♦ GS compliance

Preliminary Steps

• Ensure DC pow er is applied t o the PoE Midspan, using stranded tinned

copper 16 AWG cables for each t erminal (r ated for 2 Amper es), with an
appropriate separate ground connection (when needed).

• Ensure that the output Ethernet c able is connected to the "DATA &

POWER OUT" port.

• Verif y that an Ethernet compatible d evice is connected to the outpu t

Ethernet cable, and that i t is arranged to r eceive 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 l ocated on a desktop/ floor or mount ed 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 conne ction cable are not supplied wit h the

product

: Before mounting the PoE Midspan to a fixed location:

• Make sure the PoE Midspan and the airflo w to it, are not covered or

blocked by any foreign objects. Keep the PoE Midspan away from
excessive heat and humidit y and ensure it is free from vibration and
dust.

• Ensure that the total Ethernet cable length does not exceed 100 met ers

(333 feet). The PoE is not a repeater and does not amplify the Eth ernet
data signal.

• A splitter may be used if desired ; ensure that the spli tter is connected

close to the PD but not to the Mids p an.

• 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 termin al (rat ed for 2 Amperes), and tighten the
2 Cable inlet screws (See Figure 2).

• Connect the “DATA IN” jack (input) to the data source (s witch) and the

“DATA & POWER” jack (output) to the t erm i nal (P D) (See Figure 3).

• Turn on the DC power source and ch eck the app ropriat e LED indica tors

to verify that power is on

continuously lit.

The PD
(Powered

Device)

does not

operate

1. Check the Midspan’s LED indicators.

2. Remove and re-apply power to the

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, straight­wired four pairs cable.

5. Verify that the PD is connected to the
"DATA & POWER OUT" port.

6. If an external po wer splitter is in use,
replace it with a splitter known as
good.

The end device

operates,
but there is
no data link

1. Verify t hat 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, straight­wired 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 spl itter is in use, replace it with a
