Trouble Shooting Procedures
The following procedure provides a step-by-step process for identifying and rectifying
installation problems with the Switch Module and Remote Module. Each step is a question
requiring a “Yes” or “No” response. Each response has a series of checks or actions
necessary to correct the problem.
Prerequisites:
ƒ Both units must be powered-up with some LED blinking patterns visible.
ƒ Both units must be connected to an active network capable of sending and receiving
packets.
System Status LEDs
After the units have completed the self-diagnostic tests, is the Status 1 LED on (solid
green) on each unit? If the Status 1 LED is not lit, check that the power cable is properly
connected. Below is the complete list of the System Status LEDs:
Syste

Port Status LED
After the units have gone through the self-diagnostics tests and loading the runtime image
(the unit’s software), the telephone port LED should be solid green. This indicates that the
telephone port is connected to a digital port on the PBX and to a telephone connected to
the Remote Module, but not extended.
1. If the port LED blinks with a green flicker this indicates that the port is enabled but
there is a bad connection to the PBX or phones.
2. If the ports are ready, press ‘1’ to connect to the Switch Module. As the telephone is
connected the LED will begin to flash slowly. This means that the telephone is
enabled but still not in use (on-hook).
3. Check the log messages within the MC for obvious port errors.
4. Are there any messages displayed on the telephones connected to the Remote
Module?
5. Place a call using a telephone connected to the Remote Module. As the remote user
places a call the LED will begin to flash faster. This means that the telephone is
extended and in use (off-hook) by the remote user.
6. Check the wiring to the PBX.
