DHU Laser Diode does not detect any optic output power.
② PD Fault: Displays the alarm state of the Laser Diode. Generates alarm when the
DHU Photo Diode does not detect any optic input power.
③ Optic RF Fault: Displays the alarm state of the Amplifier of the Optic module.
④ LD Power: Displays the Laser Diode optic output power.
⑤ PD Power: Displays the Photo Diode optic input power.
4. Environment
① AC Fault: Displays the alarm state of the main input power of the DHU.
② DC Fault: Displays the alarm state of the power supply of the DHU. Generates an
alarm when the DHU power supply detects a fault in its circuit.
③ Batt Fault: Displays the alarm state of the Battery of the DHU.
④ Hi Temp: Displays the alarm generated when the detected DHU temperature is
higher than the set ⑧ Hi Temp.
⑤ FAN Fault: Displays the alarm state of the Fan of the DHU.
⑥ Door Open: Displays the alarm state of the Door of the DHU.
⑦ Low Temp: Displays the alarm generated when the detected DHU temperature is
lower than the set ⑨ Low Temp.
⑧ Hi Temp: Sets/Displays the maximum temperature limit.
⑨ Low Temp: Sets/Displays the minimum temperature limit.
⑩ Temp: Displays the current temperature of the DHU.
⑪ Current: Displays the amount of current consumed by the repeater.
5. DL
① DL RF Fault: Displays the alarm state of the Downlink Amplifier.
② DL-0 ATT: Sets/Displays the Downlink-0 attenuation. Accurately matches the input
level of the DHU to the optic module dynamic range input.
③ DL-1 ATT: Sets/Displays the Downlink-1 attenuation. Accurately matches the input
level of the DHU to the optic module dynamic range input.
