PRODUCT DESCRIPTION AND USER’S MANUAL

Alarm Fault and most probable cause and Recommendation

causes (sun, hot environment, air flow is blocked). Eliminate the

reason for excessive heat.

Donor Power

Too Low

Description: Signal from the Donor antenna (DL) is too low -

relatively to the desired output signal configured by the user.

Recommended action:

• Check the Donor/Base connections and antenna position.

• Check the signal level of the Donor/Base antenna.

•

If the Donor Power Too Low alarm is still raised, then you can

raise, the value of the DL Output Threshold Delta[dBm] as

needed

(PAmp)

Current

Description: Power Amplifier current is not within limits (too high

or too low). If the Mute option is enabled, then this is not a fault

since it indicates low Power Amplifier current caused by the mute.

Recommended action: Check the LEDs status in the Repeater

and Contact Axell service support.

RSSI Description: Generates an alarm when a high donor input signal

causes system gain reduction

VSWR Description: This alarm is triggered when the return loss of the

Downlink or Uplink antenna or cable connection exceed the allowed

limit.

This alarm provides an indication of the status of the cable/antenna

connected to the antenna. If a cable/antenna is defective, the

VSWR is decreased and the alarm is triggered.

Recommended action: Check the cable.
