Amplifier Set-up

2.4.1. Amplifier LED Indicators

The MAXNET II QMP200 Amplifiers have two LED indicators: PWR and ALM.

The PWR (Power) LED verifies that the amplifier module is receiving power from the MAXNET II Power Supply

through the 24 VDC Chassis Bus. The PWR LED is always solid green when the module is powered. If no powering

is available then the PWR LED is off. The PWR LED does not have a flashing condition.

The ALM LED will FLASH RED if there is a problem with the amplifier or if any of its monitored functions are beyond

the specified limits (e.g. absence of RF input signal).

2.4.2. Amplifier Front Panel Controls (Padding & Equalizer)

The QMP200 Amplifier plug-in padding and plug-in equalizer are accessible by removing the front cover. Remove the access

cover from the front of the QMP200 Amplifier module by turning the thumbscrew counter-clockwise. This will expose two

blocks of two PAD's/EQ's. The ones on the left side are connected to the RF Input and the ones on the right side are

connected to the RF Output.

__________________________________________________

If the ALM LED is flashing red at a slow rate of approximately 1s on-1s off, this is indicative of a communications failure between this module and

the chassis. See Troubleshooting section.
