Chapter 2 Preparing for Installation
Preparing Your Site
The supplier of the fiber-optic cable may have a test report available. If no report
is available, remote link tests must be performed to verify that parameters are
within specifications. Table 2-2 lists the remote link tests required, the
measurement the test is to be specified in, and the instrument required to perform
the test.
Cord Selection for Operation in USA and Canada
Use a detachable electrical cord with national certification (type SVT or SJT).
One end terminates in a NEMA-style attachment plug rated for supply voltage
(120V or 240V), and the other end attaches to an IEC 320-type appliance coupler.
Warning This unit might have more than one power cord. To reduce the risk
of electric shock, disconnect the two power supply cords before
servicing the unit.
Preparing Your Site
This section describes the various tasks required for preparing your site for
installation, and it indicates who (you or the Cisco authorized representative) is
