Arrange the cable to prevent it from dislodging or developing stress points. Secure

the cable so that it is not supporting its own weight as it hangs to the floor. Place
excess cable out of the way in a neatly coiled loop. Placing fasteners on the loop helps
to maintain its shape.
Verify that the FIC or PIC is functioning correctly by noting whether the normal function

indicator LED is lit. The normal function indicator LED is usually green; for more
information, see the M7i Multiservice Edge Router PIC Guide.
You can also verify correct PIC functioning by issuing the
command, described in "Maintaining the M7i FIC and FIC Cables and PICs and PIC
Cables" on page 70.

Small form-factor pluggables (SFPs) are optical transceivers that can be removed from
a PIC (for more information, see "M7i PICs Description" on page 16).
SFPs are hot-insertable and hot-removable. Removing an SFP does not interrupt PIC
functioning, but the removed SFP no longer receives or transmits data. To replace an
SFP, perform the following procedures:
