Power off the chassis by disconnecting both power cords
from the power supplies and the power sources. Set the cords aside
for use with the new installation.
After ensuring that the cables are properly labeled, and
the port connection information is recorded (see Cable routing table), disconnect the cables and transceivers
from the ports. Use the pull tab on the 16 Gbps SFP+ transceivers
to remove the fiber cable and the attached SFP+ at the same time
(see Installing an SFP+ transceiver).
Group the cables together and position them safely away
from the switch to avoid damage during the chassis replacement process.
