Installation Completion

To set the neon voltage ring ping:

1.Call a telephone with a neon message indicator and leave a message.

2.Check for “ring ping” (single ring pulse) each time the lamp flashes (approximately every 3 seconds).

3.Adjust the control clockwise in small increments until the ring ping stops. Be sure that the message lamp still lights when the adjustment is finished.

Installation Completion

To complete the installation:

1.Type logoff and press Enter to prevent unauthorized changes to data.

2.Set the left and right doors onto the hinge pins and close the doors. The doors must be closed to prevent EMI emissions. Tighten the door screws.

3.Set the right cover panel onto the right panel and secure. Do not use force.

Power Supply LED Indications

It is not possible to view the alarm log to determine which power unit in a multi-cabinet system is defective. Use the LEDs on the front of each power unit to determine its state.

Table 30 shows the LED and alarm conditions. Ring voltage and neon bus output do not activate alarm status.
