In the downlink (DL), the Node AM4 picks up signals coming from the base station, filters them, amplifies them, and retransmits them to the mobile. In the uplink (UL), it picks up signals from the mobile, filters them, amplifies them, and retransmits them to the base station.
Connect power and the antenna coaxial cables to the Node AM4. Open the small User Interface cover plate Establish a connection from the laptop or computer to the Node AM4. Login to the unit and use the Technician Setup page (see Software manual) for configuration.
Node AM4 is 220 m³/h which will be reached at an environmental temperature of around 45°C and above. We suggest to supply the repeater at the air inlet with fresh air and to conduct warm air at the air outlet off the Node AM4 without feedback in order to avoid a 'thermal short-circuit'.
Note: because it is required if the Node has to be sent back, e.g. for a repair or upgrade. 3.1.4. 19 Inch Rack Mounting of the Node AM4 1) 19’’ Rack for Node AM4 (and LMR450) rack mounting 2) Mounting material:...

4.3.4. Power Supply Unit The power supply unit is mounted in the interior cabinet of the Node AM4. This device transforms mains power into predefined DC voltages. When performing maintenance, ensure that all circuits are voltage-free and that the Node AM4 is disconnected from mains.
To delete the false alarm, the unit has to be shut down and powered up again. During shutdown, the battery disconnect button must not be pressed see also notice in chapter 5.2.2). The following figure illustrates the general type; of UI1 Board. MF0121ACP_uc.docx Manual for Node AM4 Page 41...
The external alarms are used to monitor the status of one or more external devices via the Node AM. A UPS or entry alarm is among the items that might be connected to the contact relay and monitored via the Node AM4. The cage clamp connectors are located on the UI1-board.
The summary alarm is a DC potential-free contact relay. Observe that the cross-sectional area of the wires to be connected must be in the range from 0.4 – 0.8 mm (AWG 26-20). Pin No.: figure 4-13 Summary alarm relay Page 44 MF0121ACP_uc.docx Manual for Node AM4...

Maintenance of the Node AM should be performed on a field replaceable unit (FRU) basis only. Do not damage the warranty labels on the components as this voids the warranty. Unless otherwise agreed to in writing by CommScope, CommScope’s general limited product warranty (http://www.commscope.com/Resources/Warranties/) shall be the warranty governing the Node AMs, including the installation, maintenance, usage and operation of the Node AMs.
This is to avoid possible damage when inserting the new RF card. If any FRU not contained in the following chapter needs to be replaced, please contact customer service for additional instructions. Page 54 MF0121ACP_uc.docx Manual for Node AM4...
Note: Removal and installation of a combiner on-site must only be done by a service technician of CommScope or by a qualified person authorized and trained for this procedure who is observing the corresponding safety procedures required by local, regional and country-specific regulations which have to be observed during all times of this procedure.
Page 56
Attention: Be careful with all cables connected. Do not squeeze or damage any cables, and make sure that no cables get disconnected by accident.
