¶ Troubleshooting
¶ Noise/Hum on One-Way Speakers
- Confirm power supply termination / connections. If power supply is suspected of inducing noise on the line, disconnect and utilize 2x 9V batteries connected in series as a temporary test measure. This will replicate a 24VDC power signal to the Valcom one-way speakers.
- Confirm installation of an audio isolation transformer between IP/Analog gateway (i.e. VE8004) and speaker runs. There may be a ground loop being induced on the line. A device such as Valcom VMT-2 may resolve this issue.
¶ Application Server Not Communicating
- Verify that the front panel power LED is illuminated
- Verify network connections, cables, network firewalls, and VLAN port (if configured)
- Scan your PA network with the VIP-102B tool. Does the Application Server show up? Confirm IP address.
¶ Grayed-Out Valcom Tablet / Console
- Grayed out console/tablet which indicates the handset was not connected all the way to the console base
¶ Orange LED
- If front panel power LED flashes a single white and three orange lights, you will need to send the application server in for repair
¶ Site Manager Not Accessible
-
Confirm that the PA headend equipment, the Site Manager (Dell PC), and the associated network switches are powered on.
-
Verify that the PA rack is properly connected to the PA network.
-
Check that the Site Manager (Dell PC) front-panel white power LED is illuminated.
- If the LED is not illuminated, press and hold the power button using a small terminal screwdriver until the white LED turns on.
- Allow several minutes for the system to fully boot, then test the bells.
- If the white power LED is already illuminated, perform a power cycle:
- Press and hold the power button (using a small terminal screwdriver) to power down the unit.
- Wait approximately one minute, then press and hold the power button again until the white LED turns on.
- Allow several minutes for the system to boot, then test the bells.
