2. Power off the chassis by flipping all ac power switches to the off position " O "
(the LEDs inside the clear plastic ac power switches should turn off).
3. Remove the power cords from the power supplies and the power outlets.
4. Label the cables connected to all blades, if not already labeled, and record the
connections in the Table 19 on page 129, making extra copies as needed.
5. Disconnect the cables from the SFP+ transceivers in the application and port
blades and set them aside. If you have mSFP transceivers in FC8-64 port
blades, or QSFP transceivers in FC16-64 port blades, remove the transceivers
and cables together and set them aside. The SFP+ transceivers can be left in the
port blades or removed.
Note: Follow the instructions in “Removing and installing transceivers” on
page 108 for more details.
6. Disconnect all cables from the control processor and core switch blades.
7. Disconnect any ICL or QSFP cables (see “Removing and replacing inter-chassis
link (QSFP) cables” on page 113).
