Ping the EUM

Note that the EUM3006 may be on a different sub-net than the end-user’s PC, so pinging the

IP address assigned to the EUM3006 will go through the CCU. Therefore, we ping the

EUM3006 using the local link IP address as the 1st test.

1. Ensure the end-user’s PC is configured with an IP address of 169.254.10.251,

netmask = 16 (or 255.255.0.0). See Setup Menu on page 15 for more information.

2. Ping the EUM’s local-link IP address 169.254.10.250, from the end-user’s PC, as

follows:

• Open a DOS window in the end-user’s PC.

• At the command prompt, type ping 169.254.10.250 and press Enter.

3. If there is no response, check the following:

• The end-user’s computer IP address settings.

• The Ethernet link light on the PC.

• The Ethernet crossover cable between the PoE Injector and the end-user’s

PC, to ensure that the pins have not been damaged.

• The PoE Injector’s POWER LED should be on.

• The Ethernet cables are plugged into the correct ports of the PoE Injector.

• If you have an MDB1000, cycle the power at the PoE Injector to reboot the

EUM3006 and verify that the EUM3006 is communicating with the MDB1000.

Note that the MDB1000 needs to be near the EUM3006. Also, if the EUM3006

has been on for more than 1 hour, it will have stopped sending the magnetic

signal to the MDB1000, hence the reason for cycling the power on the

modem.

4. If there is a response, but with errors, check the Ethernet crossover cable.

This is what a successful ping from the end-user’s PC to the EUM looks like:

C:\>ping 169.254.10.250
