To interconnect two Virtual Chassis for QFabric system control plane redundancy (see
Figure 59 on page 226 and Figure 59 on page 226 ):
WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to transceivers emit laser light that can damage your eyes.
1.
If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap.
Save the cap.
2.

Secure the cables so that they are not supporting their own weight. Place excess cable
out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain
their shape.
