If the DCP phones connected through the Avaya R300 are not receiving power, do the 
following:

■

Verify the phones are supported by the Avaya R300. For valid phone types, see the 
supported station tables in Chapter 1.

■

Verify that the phones are properly plugged into the Avaya R300 Interconnect. (Hit 
the “Test” button.)

■

Verify that the Interconnect unit’s power cord is plugged into the outlet and that the 
outlet is live.

■

Verify the -48 volt power source works properly.

■

Verify that both plugs from the Y-cable (DCP and analog/power) are correctly 
plugged into the Interconnect unit.

■

Verify the Y-cable is correctly plugged into the Combo Blade Card on the Avaya 
R300 unit.

If the phones connected through the Avaya R300 do not have audio signal, do the 
following:

■

Verify the phones are getting power by pressing the TEST button (DCP phones 
only). The LED next to the Test button should light. If the LED does not light, the 
phone is not getting power, and you should refer to the section Phones Not 
Receiving Power for a solution.

■

Verify IP connectivity between the Avaya R300 and the DEFINITY Gatekeeper 
(C-LAN). Go to terminal server mode (Ctrl-d then e). Type “ping <C-LAN IP 
address>”. If this fails, refer to the section No IP connectivity between Avaya 
R300 and DEFINITY Gatekeeper (C-LAN).

■

Verify IP connectivity between the Avaya R300 and the DEFINITY Media 
Processor. 

■

Go to terminal server mode (Ctrl-d then e). 

■

Type “ping <Media Processor IP Address>.” 

■

If this fails, refer to the section No IP connectivity between Avaya R300 
and DEFINITY IP resource.
