Because DMC Stratex Networks is constantly seeking to improve quality and performance,
specifications and configurations may be subject to change without notice. As periodic
changes are made to the information contained herein, DMC Stratex Networks will
incorporate these changes into any new versions of this manual as they are released.

While every effort has been made to verify the operation of DXR100 with many different
communications products and networks, DMC Stratex Networks makes no claim of
compatibility between DXR100 and other vendors' equipment. It is assumed that users have
thoroughly evaluated the performance of DXR100 in the environment in which it is to be
used.

)GPGTCN
Please observe the general safety precautions outlined in this section during all phases of
operation and service of DXR100. If you do not comply with these precautions or with
specific safety warnings contained elsewhere in this manual or on the product itself, you will
violate the standards of design, manufacture, and intended use of the product. DMC Stratex
Networks does not assume any liability for any failure to comply with these precautions.
To help you to easily recognise safety warnings or precautions contained in this manual they
are prefixed by the warning symbol shown above.
)TQWPFKPI
The DXR100 chassis must be grounded. If a short circuit occurs, grounding will reduce the
risk of electrical shock by keeping the equipment at the same potential as a person touching it.
Do not remove the external covers unless you are authorised to service the equipment.
%JCUUKU6GORGTCVWTG
The DXR100 chassis is designed to conduct any heat generated by the DXR100 internal
components to the outside environment. Therefore, it can become uncomfortably warm to
