About the Power over LAN Midspan
PowerDsine’s family of Power over LAN Midspans, series 3000, injects power
over data-carrying Ethernet cabling. The PD-3006/3012 Midspans, support 6
and 12 ports respectively in a 10/100BaseTx Ethernet network, over TIA/EIA-
568 Category 5/5e/6 cabling. The DC operating power for the 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 splitter in order to be powered.
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)
* Power management for PD-3012 only
* Independent overload and short-circuit protection per channel
* Port status indications
* Optional 19-inch rack kit.
2.1
Power Management (PD-3012 only)
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 (92 W). 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 out-of-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 port 12 down until the total power is once again under the
maximum limit.

10/100BASE-TX Ports Definition
2.2.1
Data Input Ports
The Midspan has 6 (or 12) 10Base-T/100Base-TX- data input ports,
configured in a non-crossover manner (straight-wired). These ports, shown in
Figure 2-1 (bottom row of connectors), are designed to carry Ethernet data
only (Tx/Rx) over the standard 2-wire pairs (pins 1/2 and 3/6).
2.2.2
Data & Power Output Ports
The Midspan has 6 (or 12) Data & Power ports also configured in non-
crossover 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).
According to IEEE 802.3 standard, the maximum allowable distance
between two Ethernet links is 100 m (328 ft). The Power over LAN Midspan
is garanteed to work up to this distance.
Figure 2-1: Power over LAN Midspan, Front View (PD-3012)
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 Indicator
A Main (power) indicator on the front panel, shows the status of the Midspan.
This indicator illuminates green when power is applied to the Midspan. In case
of a problem with the device, the indicator illuminates in orange.

2.3.2
Port Indications
The status of each port is monitored by a bi-color LED indicator (green and
orange). Green indicates that the PD has been identified as "Power over LAN
enabled", is active and is receiving power.
Orange indicates that the port is not supplying power and is not active. Refer
to Table 2-2 for additional information.
In the event that an Ethernet device that is not Power over LAN enabled is
connected to the Power over LAN Midspan (indicator is orange or off), the
Ethernet device will be unaffected due to the fact that power is not being
supplied.

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.
Figure 3-1: Typical Installation
3.2
Connecting 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).

3.3
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 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 the Main indicator illuminate green.
2. Port indicators and the Main indicator illuminate orange.
3. Main indicator remains lit green; port indicators are out.
Ports are now enabled for normal operation.
(optional only)
Rack-Mounting Brackets
3.4
Mounting brackets are available to install the Midspan in a 19-inch rack. An
optional accessory kit can be ordered as PowerDsine catalog number PD-
3000/MK. This kit consists of:
* Left-hand bracket (MB-6831-011)
* Right-hand bracket (MB-6831-012)
* Screws (MS-1413-001) qty 4
See Figure 3-2 for installing the brackets on the Midspan. It may be necessary
to remove the four rubber legs prior to installing the brackets, so as to maintain
a one rack-unit height. Once the brackets are installed, the device can be
mounted in a 19-inch rack assembly, using the holes shown in Figure 3-3.
Rack mounting screws are not provided.

Troubleshooting
3.5.1
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.
3.5.2
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.
Table 3-1: Troubleshooting Steps
Symptom
Corrective Steps
1. Verify that a known-good power cord is used.
Midspan does not
power up
2. Verify that the voltage at the power inlet is between
100 and 240 Vac.
3. Remove and reconnect 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.

2. Verify that the PD is IEEE 802.3af-compliant.
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.

Table 3-1: Troubleshooting Steps
Corrective Steps
Symptom
The end device
operates, but
there is no data
link.
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.
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.
Is it safe to keep

During these conditions, port power is disconnected.
