3 Installation Requirements
To achieve reliable operation, and maximum performance, an appropriate installation location must be chosen.
3.1 Outdoor Locations to Avoid
Although Ericsson declares this product suitable for most outdoor environments, this does not cover installations where
the planned installation site for the unit is a potential microclimate location. Typical examples of these microclimate
locations are sites where the products are not only exposed to the actual temperature, but also additional temperature
as heat coming from dark-colored planes, for example, reflections from the floor or walls. The additional temperature
can generate heat traps with temperatures up to 10°C higher than expected.
Avoid installing equipment in the following locations:
– Near the exhaust of the building ventilation system.
– Near the exhaust of the chimney.
– Opposite large surfaces made of glass or new concrete.
– Near overhanging structures such as roof overhangs.
Avoid radio interference by keeping the area directly in front of the antenna clear of the following:
– Metal surfaces or objects such as railings, ladders or chains
– Equipment generating electromagnetic fields, such as electric motors in air conditioners or diesel generators
– RBS equipment

3.4 Installations that Require Fan Unit
The fan unit must be used in all installation scenarios where the cables from the radio are not pointing directly
downwards. The fan unit must also be used in extreme conditions, such as installations with poor ventilation or
installations with heat traps.
3.5 Painting Disclaimer
Ericsson recommends to not paint the product as it can affect performance of the product.
Ericsson applies limitations to the warranty and service contract if the product is painted.
If the product is painted, the following commercial limitations apply:
– Failure modes directly related to overheating because of painting are not valid for repair within the scope of the
warranty or standard service contract.
– Product failures related to paint contamination of components of the unit are not valid for repair within the
scope of warranty or standard service contract.
– When a painted unit is repaired, it might be restored to the standard color before being returned to the market. It
is not possible to guarantee that the same unit is sent back to the same place. This is also valid for units repaired
under a service contract.
– For repairs within the warranty period or a standard service contract, the customer is charged the additional
costs for replacing all painted parts of the unit or the complete unit.
If adaptations are required, contact Ericsson for information.

Radio 4466 Connection to Digital Unit and Baseband per RAT
Figure 15 shows the alternatives for connection to Digital Unit and Baseband.
Figure 15 Connections to Baseband
Radio 4466 can be connected to two Digital Units (DU) or Baseband units at a maximum through CPRI ports. The
ports can be used in the following ways:
– Non-Cascading:
• With one DU or Baseband, data ports 1, 2, 3, and 4 can be used for connection to DU or Baseband.
• With two DUs or Baseband units configurations which share radio, Node Group Synchronization must be
used, see Manage Node Group Synchronization.
– Cascading:
• Two data ports work in pairs, only connections between data ports 1 to 2, and 3 to 4 are supported. Data
ports 1 and 3 can only be used as Cascade-in port for connection to DU or Baseband; data ports 2 and 4 can
only be used as Cascade-out port for connection to the next cascading radio.
• When one pair of data ports is used by cascading, the other pair can be used simultaneously only when its
both ports are used by different Baseband units.
5.1 Antenna Interface
The antenna interfaces provide connections for the radio to antennas. RF cables connect the radio to the antenna.
The antenna interfaces also provide support for control and power to ALD.
The on-off keying (OOK) is supported on Antenna A port to Antenna D port; the DC bias is supported on Antenna A port
and Antenna C port.

The ALD control (ALD Ctrl) connects an ALD (RET) cable to the radio for antenna system communication. The interface
supports 3.2 A DC.
ALD control is also supported on Antenna Interface connectors.
5.6 Optical Cable Interface
The optical cable interfaces provide connections to optical cables for traffic and timing signals between Radio 4466
and a baseband unit. An SFP is used to connect the optical cable to Radio 4466.
Note: There are different SFP modules for different products.
Only use SFP modules approved and supplied by Ericsson.
For recommended SFP modules, see SFP Module Selector Guide.
5.7 −48 V DC Power Supply Interface
The −48 V DC power connection is made through a connector with a 3-wire (DC-I) connection or a connector with a 2wire (DC-C) connection.
For power cable dimensioning, see Site Installation Products Overview.
For determining which connector or junction box to use, see Table 29
