6. Maintenance
6.1. General
Read and observe chapter 1.2 Health and Safety.
Caution: The unit reaches high temperature in operation. Risk of burns by hot
surface. Do not touch the unit before it has sufficiently cooled down.
 Note: The Remote Unit does not require preventative maintenance measures.
 Note: We recommend checking the cleanliness of the unit and in particular of
the heat sink / fan (for units with active cooling) at appropriate intervals
depending on the degree of dust and dirt at the installation site. If
necessary, any dusty or dirty areas / parts should be cleaned at regular
intervals, which also depend on the degree of dust and dirt at the
installation site.
Maintenance of the RU should be performed by replacing only components that are
contained in this section. Take care not to unintentionally damage the seals on the
modules to maintain warranty. Please keep these guidelines in mind during
maintenance:
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 Remote Units, including the installation, maintenance, usage
and operation of the Remote Units.
The spare parts list, consequently, contains only units which can be replaced without
tuning or soldering work.
 Note: Ensure the Remote Unit has been disconnected from mains power
during maintenance of active cooling units.
 Note: When sending back the unit, use appropriate packaging (see also
section 7.2.3 Mechanical Specifications for details). Use of the original
packaging for shipping the unit is strongly recommended.
 Note: Defective parts should only be replaced by original parts from the
supplier. All service work performed inside the housing is performed at
the users own risk.
 Note: Label any unlabelled cables before disconnecting them to ensure
correct reconnection.
For most maintenance procedures, appropriate tools are required to ensure correct
handling. All of these tools can be ordered from the supplier.
 Note: All Remote Unit screws have a right-hand thread, and are tightened by
turning the screws clockwise and loosened by turning them counter-
clockwise with an appropriate tool.
Due to the design of the Remote Unit the only component recommended to be
replaced is the fan unit (only equipped in units with active cooling). For replacing any
other component, please contact the supplier.
