General Troubleshooting Steps
1. Verify the status of the LEDs on the controller. See “Checking the
Status LEDs” on page 217.
2. From the Maintenance Terminal, review the Alarm details. Identify and
fix each alarm.
3. For IP Phone and physical network connectivity problems:
- Verify that the phone has power. (The display lights up if the phone
is receiving power from the Layer 2 port).
- Verify the status of the port link integrity LEDs at each end of the cable.
- Verify that each device transmits a link integrity pulse (LINK LED on).
- Verify that proper cabling is installed between the end devices.
- Verify that a crossover cable was not used to connect the IP Phone
to the controller instead of a straight-though cable.
If the IP phone still fails, try plugging it into the port of a working IP
Phone (isolates problem directly to phone or programming if phone
fails to boot) or directly into the SX-200 ICP (do this after hours since
all other phones will be out of service.)
