  • Page 4: Revision History

    Revision History RTI-PoE4N - Base Model 1.1. The Model RT-PoE4N is the initial version in production. It can be recognized by the version string as follows (see the VERSION command; also seen on power-on). Reach PoE Tester Model RT-PoE4N/24 PN 53-0003-11 Rev A 01 SW 1.02 07/01/2014 Copyright (C) 2005-2014 by Reach Technology Inc.

  • Page 5: General

    24 Powered Device (PD) loads in a 1U high chassis. Each RT-PoE4N port passes up to GbE speed traffic to the next port to facilitate data traffic testing. That is, Port 1 data connects to Port 2, 3 to 4, and so on. This is useful when the PSE has diagnostics to do port-to-port traffic testing, or when the PSE is set up for port pair VLANs to force traffic through all ports.

  • Page 6: Features

    1.74" high Electrical Characteristics 2.5. The RT-PoE4N 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...

  • Page 7: Configuration Guide

    UUT (Unit Under Test) Connections 3.3. The RT-PoE4N has twenty-four identical test ports. Connect the port of the PSE (PoE Supplying Equipment) under test to the port connector via a standard straight through Ethernet cable. The PSE data will be routed to the next port (1 to 2, 3 to 4, etc) on a straight-through, non-crossover basis.

    RJ-45 Ethernet Connectors 4.1. Picture 2: Far left side of RT-PoE4N 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...

  • Page 9: Ethernet Power Selection

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

  • Page 10: Operational Overview

    Operational Overview Data path 5.1. The data path section allows the UUT port data to be in two states: disconnected, or connected to the data of the next UUT port. This allows data to pass from port to port for testing.

  • Page 11: Power Input

    Power input 5.2. Power Input (above); 2 instances, one for each power pair: Each UUT port can have either power pair measured (reported voltage can be positive or negative depending on polarity), or connected to the Full Wave Bridge and subsequent load circuits.

  • Page 13: Fans

    Fans 5.4. The fans engage when any of the test ports have been issued the “connect” command. After all ports are no longer connected (e.g. reset command has been issued) the fans will stay on until nominal heatsink temperature has been reached. RJ45 LEDs 5.5.

  • Page 14: Command Reference

    This section describes the commands available. For typical command sequences, see Appendix When the unit is ready for a command, it issues the default prompt "RT-PoE4N>". The prompt may be changed via the "hostname" command so that a unit can be identified by its prompt.

  • Page 15: Error Check

    ERROR CHECK Description: The unit maintains an error flag that is set if any error message is generated. This command reports the error flag value. A test script can run an entire sequence of commands and check at the end to make sure there were no errors instead of having to check on a command-by- command basis.

  • Page 16: Echo

    ECHO Description: Used to test the communication between the host and this unit. This is useful at higher baud rates to validate a baud can be used without error. A script can repeat the echo command continuously and verify that no communication errors are present.

  • Page 17: Cap

    Description Controls the 10uF capacitor across the full-wave bridge. This represents either a legacy capacitive signature or an AC load. cap [on|off] Command: printf(":p%d cap %d\r\n", port, state); Response: state = 1 or 0 for on and off respectively. CLASS Description Sets the IEEE load class.

  • Page 18: Connect

    CONNECT Description Controls the relays that connect the power load circuitry to the UUT port via the GbE transformer. From a power perspective, this is equivalent to plugging in the RJ45 from the UUT. See the Operational Overview section for more details. Connect must be on for the UUT to see an IEEE 802.3af/at PoE load.

  • Page 19: Measure

    MEASURE Description Measures the voltage from the UUT (center taps of GbE magnetics) of the main. Reports the voltage as either positive or negative depending on the polarity of the pair. The “Cisco” standard 1,2 = negative, 3,6 = positive is reported as a positive voltage. meas[ure] Command: printf(":p%d %d.%uV\n\r",port,fval);...

  • Page 20: Set

    Description Sets power load value in milliamps. If set too low, the minimum value will be set; if at or above 1400mA an error will occur. Note that this is the load for both the main and the alt pair. set <value>...

  • Page 21: Appendix A - Operational Notes

    When the unit is powered on, it performs a self-calibration of its power load. This takes around 10 seconds. While calibrating, the unit flashes the front panel LED and displays the following. The prompt "RT-PoE4N>" indicates that the unit is ready for commands. RT-PoE4N>”(revision dependent version string)”...
