2 About the Power over LAN Midspan
PowerDsine’s family of Power over LAN Midspans, series 6000, injects power
over data-carrying Ethernet cabling. The PD-6006/6012/6024 Midspans,
support 6, 12 and 24 ports respectively in a 10/100BaseTx Ethernet network,
over TIA/EIA-568 Category 5/5e/6 cabling. DC operating power, for data
terminal units, is fed over unused pairs of the cabling (7/8 and 4/5).
The Power over LAN Midspan normally powers devices that are Power over
LAN enabled or are equipped to receive power over Ethernet. These devices
are called Powered Devices (PDs). Devices that are not equipped to receive
power over Ethernet may require an external power adapter in order to be
powered. Contact PowerDsine for such an adapter.
Power over LAN Midspan main features:
Remote power feeding of Ethernet terminals
Eliminates the need for AC outlets, local UPS and AC/DC
adapters
Universal range power input (100-240 VAC, 50/60 Hz and/or
46 to 57 VDC)
Power management
SNMP management (optional)
Independent overload and short-circuit protection per channel
Port status indications
Standard 19-inch rack mountable.
2.1 Power Management
When establishing a network, the total power required by PDs may exceed the
total power available from the Midspan. The built-in Power Management
feature will not allow the total power output to exceed the maximum power
available (refer to the Technical Specifications). When the total power
available is near maximum, attempts to connect an additional PD to a free port
will cause the corresponding LED of the port to blink orange, indicating an outof-power budget. This port will not deliver power. Power distribution is based
on “first come, first served” logic.
It is possible that connected and operating PDs will significantly increase or
suddenly raise their power requirements. If the power required exceeds the
power available, the Power over LAN Midspan will start to turn off ports,
starting from the last port down, until the total power is once again under the
maximum limit.

PD-6006/12/24
2.2 10/100BASE-TX Ports Definition
2.2.1 Data Input Ports
According to the model acquired, the Midspan has 6, 12 or 24 10BaseT/100Base-TX- data input ports, configured in a non-crossover manner
2-1 (bottom row of connectors),
(straight-wired). These ports, shown in Figure
are designed to carry Ethernet data only (Tx/Rx) over the standard 2-wire pairs
(pins 1/2 and 3/6).
2.2.2
The Midspan has 6, 12 or 24 Data & Power ports also configured in noncrossover manner (straight-wired). These ports are designed to carry Ethernet
data over the standard 2-wire pairs (pins 1/2 and 3/6) and DC power over the
spare pairs (pins 4/5 and 7/8).
The Power over LAN Midspan is not a repeater. As such, the maximum distance from the
Ethernet switch is not to exceed 100 meters (328 ft). In accordance with the IEEE 802.3
standard, the Power over LAN Midspan is guaranteed to work up to this distance.
Data & Power Output Ports

2.3 Indicators
A set of indicators provide the status of the Power over LAN Midspan and its
ports. Refer to Table
2-1 and Table 2-2 for status information during operation.
2.3.1 Primary Power Indicators
Depending on the configuration ordered, there may be two LEDs on the front
panel, marked by “AC” and “DC”, to provide the Power over LAN Midspan
power status. When either one of the indicators is illuminated in green, the
Power over LAN Midspan is receiving AC or DC power. The “AC” and “DC”
indicators are lit in orange to indicate an internal fault. Refer to Table
additional information.

2.4 Connectors
The front panel of the Midspan includes a Console port (DB-9 connector). The
user may connect a terminal and perform software loading, via this connector,
using a standard null modem cable. The console port is set to 19,200-baud, 8
data bits, no parity and 1 stop bit. Pin connections for this connector are:
Pin 2 is Receive (RXD) Pin 3 is Transmit (TXD)
Pin 5 is Ground Pins 1 and 6 are shorted
Each data port is configured
as shown in Figure

3 Installing the Power over LAN Midspan
3.1 Background Information
As shown in Figure 3-1, the Midspan is connected in series to an Ethernet
switch/hub. The data outputs from the switch are connected to the Midspan.
The Midspan delivers power over spare twisted pairs (pins 7/8 and pins 4/5) of
the Category 5 cabling, without degrading the quality of data communications.
Most installations require the Midspan to be rack mounted, as described
hereafter.
Figure 3-1: Typical Installation
3.2 Rack Mounting Brackets
The Midspan comes with 19-in.
mounting brackets and screws. To
install the Midspan into a 19-in.
rack, first remove the selfadhesive rubber feet from the
bottom surface. Install the
brackets using two screws per
side. Rack-mounting screws are
not provided.

Power over LAN Solutions 11 Cat. No.: 06-6800-056
3-2: Installing Mounting Brackets
PD-6006/12/24
3.3 Connecting Ethernet Cables
The ports on the front panel of the Midspan are configured as "route through"
ports for all eight conductors of the RJ-45 connectors. Use Category 5 cabling
in making connections.
1. Connect cables from the Ethernet Switch to the Data ports (bottom
row on Midspan).
2. Connect the cables from the IEEE 802.3af ready terminals (PDs) to
the corresponding Data & Power ports (top row on Midspan).
3.4 Connecting Power Cables
When using AC to power the Midspan, plug in the power cord supplied, at the
rear AC connector. If DC is to be used (as primary or back-up power), connect
the DC primary wiring to a Molex P/N 44441-2002 connector, with 2 Molex
terminals P/N 4330-75/0001. Pin 1 is the positive polarity of the DC connector,
at the rear of the chassis.
3.5 Powering up
The Power over LAN Midspan has no on/off switch. To apply or remove power
to the Midspan, insert or remove the power cable from the receptacle(AC
and/or DC) on the rear panel of the unit.
With power applied, the Midspan powers-up and the internal fan operates;
then, the device runs through its power-on self-test (POST), which takes less
than 10 seconds. During the POST, all ports are disabled and the indicators
illuminate in the following sequence:
1. Port indicators and power indicators (AC & DC) illuminate green.
2. Port indicators and the AC indicator illuminate orange.
3. Main (AC or DC) indicator remains lit green; port indicators are out.
Ports are now enabled for normal operation.
3.6 Troubleshooting
3.6.1 Preliminary Steps
If you encounter problems, check that:
Power is applied to the Midspan
A crossover-type Ethernet cable has not been used
The Ethernet cable from the network is connected to the Data port
The Ethernet cable to the PD is connected to the Data & Power port
Cable pairs are attached to corresponding ports.

3.6.2 Troubleshooting Guide
This paragraph provides a symptom and resolution sequence in order to assist
in the troubleshooting of minor operating problems. If the steps given do not
solve your problem, do not hesitate to call your local dealer for further
assistance. Refer to Table 3-1.

1. Verify that a known-good power cord is used.
2. Verify that the voltage at the power inlet is between 100
and 240 Vac.
3. Remove and re-apply power to the device and check the
indicators during power up sequence.
Power-on self-test failed: the Midspan detected an internal
fault. In this case, contact your local dealer.

A port indicator is
not lit and the
corresponding PD
does not operate.
The end device
operates, but there
is no data link.
1. The Midspan did not detect a PD and therefore the port is
not enabled.
2. Verify that the PD is designed for Power over LAN
operation.
3. Verify that you are using a standard Category 5/5e/6,
straight-wired cable, with four pairs.
4. If an external power splitter is in use, replace it with a
known-good splitter.
5. Verify that the PD is connected to the Data & Power port.
6. Try to reconnect the same PD to a different port on the
same or into different Midspan. If it works, there is
probably a faulty port or RJ-45 connection.
1. Verify that the port indicator on the front panel is
continuously lit.
2. If an external power splitter is in use, replace it with a
known-good splitter.
3. Verify that for this link, you are using standard UTP/FTP
Category 5 straight (non-crossover) cabling, with all four
pairs. Check that the link is 100 m or less.
4. Try to re-connect the same end device into a different
port on the same unit or into different unit – if it works,
there is probably a faulty port or RJ-45 connection.

Table 3-1: Troubleshooting Steps
Symptom Corrective Steps
Is it safe to keep
the Midspan
running while a port
indicator is orange?
This is a safe condition. The orange indication is due to:
1. A device, not compliant to IEEE 802.3af, was detected.
2. Terminals 4/5 and 7/8 are shorted together.
3. Forced external power fed into the port.
During these conditions, port power is disconnected.
