Chapter 3: Test Equipment <strong>and</strong> Spares<br />
RECOMMENDED SPARES<br />
<strong>Daniels</strong> <strong>Electronics</strong> recommends one complete radio system spare for every ten radio systems (or less)<br />
in operation to account for lightning damage or other maintenance issues. The amount of spares could<br />
be dependant on the critical nature of the radio system <strong>and</strong> the availability of service for the system.<br />
<strong>Daniels</strong> recommends a complete radio system spare for every critical / essential site in the system. The<br />
design of <strong>Daniels</strong> <strong>Electronics</strong> Ltd. <strong>MT</strong>-<strong>4E</strong> radio systems makes it easy to swap components of a radio<br />
system <strong>and</strong> can save valuable time <strong>and</strong> effort during maintenance. The exact spares would depend on<br />
the types of systems in operation, but would typically include:<br />
Subrack / Motherboard<br />
