The Model RT-PoE4N/10G is the initial version in production. It can be recognized by
the version string as follows (see VERSION command; also seen on power-on).

2. General
2.1. Overview
Manufacturers of Ethernet Power Sourcing Equipment (PSE) such as Ethernet Switches
need to test PoE power functionality during manufacturing. Once a unit is in
manufacturing, it can be assumed that it has already been tested for full Compliance with
the applicable IEEE 802.3 PoE standard. It is not cost-effective, nor necessary, to
perform full compliance testing at the manufacturing stage. What is needed is a
functional test that verifies the software’s ability to detect and control power, and the
basic connectors’and magnetics’ability to provide power and pass data.
The Reach RT-PoE tester family has been designed for cost-effective functional
production test. It assumes that the PSE can be operated in a “diagnostic” mode whereby
the power control and detection functions of the PSE can be individually tested. The
LLDP protocol specified by the 802.3at standard is not supported so as to keep the cost of
the tester low. Most switches provide a way of bypassing LLDP to provide full power to
a particular port. LLDP is implemented in firmware: if the unit can pass data under power
it can pass LLDP packets, and so testing LLDP functionality is not necessary for a
production test.
The Reach Power-over-Ethernet Tester Model RT-PoE4N/10G provides diagnostic
functional testing of 24 PSE ports compatible with IEEE Standards 802.3af and 802.3at,
plus it will support data path speeds up to 10GBASE-T. In addition, it can test high
power ports such as UPoE that use all four pairs to provide power. It can draw up to
660mA per power pair while passing 10Gb traffic. It provides high density with 24
Powered Device (PD) loads in a 1U high chassis.
Each RT-PoE4N/10G section has a “UUT” port (Unit Under Test). The UUT port is
connected to the PSE and acts as a PD load to that port. The UUT data path is connected
via power-isolating magnetics to the adjacent UUT port (1 to 2, 3 to 4, 5 to 6, etc.). In this
way, an external data bit error tester or PSE test functionality can be used to test data
integrity while power load is enabled.

2.5. Electrical Characteristics
The RT-PoE4N/10G is powered via a locking power DIN 4 pin connector and requires
12V DC at a maximum of 8.5 Amps.
The unit is supplied with a worldwide universal AC input power supply brick. Its
characteristics are:
85-264VAC input, 87.5% efficient, 0 to 40C operation, IEC320/C14 input
2.6. Environmental
Operating temperature range is 0C to 40C. Storage is -30C to 70C.
Humidity is 85% maximum, non-condensing
2.7. Warranty
The RT-PoE4N/10G is warranted by Reach Technology against manufacturing defects
for one year.
2.8. Operating Software
No Software license is required.
2.9. Calibration
The unit performs self-calibration on power-on, or on command.

3. Configuration Guide
3.1. Power
The power input is located on the rear of the unit. The power supply provided is a
"desktop" type brick with a three prong IEC input connector. An AC power cord
compatible with U.S. power outlets is optional. There is no power switch; it is on when
the power is applied.
3.2. Serial Console
The serial console port is located at the rear of the unit. It is an RJ-45 with a three-wire
RS-232 level interface. The interface has the same pinout as found on Cisco routers and
switches. The baud rate factory default is 9600, 1 stop, no parity, 8 bits. The baud rate
can be changed by software command –see the BAUD command in the Command
Reference section. Characters are echoed as they are typed (full duplex).

3.3. UUT Connections
The RT-PoE4N/10G has 24 test ports, configured as 12 pairs (1-2, 3-4, 5-6, etc.). Each
port has the ability to act as a PD load to the UUT. In addition, each port pair can be
configured to pass data from one port to the other via internal straight through
connections, allowing the loads to be applied while passing traffic. All data path
connections are made via signal relays and 100 ohm differential pairs for data integrity.
Connect the port of the PoE supplying device under test to the UUT connector via a
standard straight through Ethernet connector (see the Ethernet Cables section for more
information regarding cables). There is an 802.3at class transformer isolating the UUT
ports in each port pair so that power can be tapped from the UUT (see the Data Path
section for more details).
Note that the devices connected to any given port pair cannot "see" the power from the
other port. In other words, the UUT ports in a port pair are connected from a data
perspective, and each UUT port connects to the RT-PoE4N/10G active load from a power
(PoE) perspective.
NOTE: with high power loads, the DC balance of the patch cables used is important to
avoid DC saturation of the Ethernet transformers. DC Balance (DC resistance per side
of the power carrying pair) should be within 3%. The standard patch cable
specifications of Cat 5, 5e, and 6 do not specify DC balance.

4. Connectors and Jumpers
4.1. RJ-45 Ethernet Connectors
Picture 2: Far left side of RT-PoE4N/10G front panel
There are 24 numbered UUT ports. The RJ connector should be cabled to the
corresponding PSE port using a standard Ethernet 1-1 jumper cable. When enabled via
software command, the data component of the port N (N=1,3,5,…) will be connected to
the data of port N+1 via Ethernet transformers and relays. This is a straight-through
connection, not a crossover.
4.2. Rear Connectors
Picture 3: Far left side of RT-PoE4N/10G rear panel
The rear of the unit, left side is shown above. The power jack is a power DIN 4 pin with
lock type, KYCON KPPX-4. Pin 1,4 are 12VDC and pin 3,4 are GND. Below that is a
console connector RJ45 three wire RS232. See the Serial Console section for pinout.

4.3. Ethernet Power Selection
Unlike the RT-PoE3N model, there are no jumpers required to set which conductors
provide power. The unit contains two separate power paths for pairs 1,2 / 3,6 and 4,5 /
7,8. These have the standard full wave bridge so any polarity is accepted. The voltage
measurement function handles either polarity and can be used to validate the expected
PSE port polarity.
