Connecting to an ePMP 1000 or ePMP 2000

Use this procedure to configure the local management PC to communicate with the ePMP module.


Select Properties for the Ethernet port.

In Windows 7 this is found in Control Panel > Network and Internet >
Network Connections > Local Area Connection



Select the Internet Protocol (TCP/IP) item:


Click Properties.


Enter an IP address that is valid for the 192.168.0.X network, avoiding:, and 192.168.03

A good example is



Enter a subnet mask of

Leave the default gateway blank.


Click OK, then click Close

Connecting to the PC and powering up

Use this procedure to connect a management PC directly to the ePMP for configuration and alignment purposes and to power up the ePMP device.


Check that the device and power supply are correctly connected (the device Ethernet port is connected to the power supply Ethernet power port).


Connect the PC Ethernet port to the LAN (AP:  “Gigabit Data”, SM:  “10/100Mbit Data”) port of the power supply using a standard (not crossed) Ethernet cable.


Apply mains or battery power to the power supply. The green Power LED must illuminate continuously.



If the Power and Ethernet LEDs do not illuminate correctly, see Testing hardware below

Testing hardware

This section describes how to test the hardware when it fails on startup or during operation.

Before testing hardware, confirm that all outdoor cables, that is those that connect the AP or SM to equipment inside the building, are of the supported type, as defined in Ethernet cabling on page 95

Checking the power supply LED

When the power supply is connected to the main power supply, the expected LED behavior is:

  • The Power (green) LED illuminates steadily.

If the expected LED operation does not occur, or if a fault is suspected in the hardware, check the LED states and choose the correct test procedure:

  • Power LED is off on page 309
  • Ethernet LED is off on page 309

Power LED is off

Meaning: Either the power supply is not receiving power from the AC/DC outlet, or there is a wiring fault in the unit.

Action: Remove the AP/SM cable from the PSU and observe the effect on the Power LED. If the Power LED does not illuminate, confirm that the mains power supply is working, for example, check the plug. If the power supply is working, report a suspected power supply fault to Cambium Networks.

Ethernet LED is off

Meaning: There is no Ethernet traffic between the AP/SM and power supply.

Action: The fault may be in the LAN or AP/SM cable:

  • Remove the LAN cable from the power supply, examine it and confirm it is not faulty.
  • If the PC connection is working, remove the AP/SM cable from the power supply, examine it, and check that the wiring to pins 1&2 and 3&6 is correct and not crossed.
