IBM service replacement responsibilities

IBM System Services Representatives (SSR) are responsible for the physical replacement and labeling of
the chassis. The SSR performs the following tasks during the replacement:

1. "Disconnecting the cables"

2. "Remove the old switch chassis and install the new switch chassis"

Disconnecting the cables

Procedure
1. 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.
2. After ensuring that the cables are properly labeled, and the port connection information is recorded
(see Appendix B, "Cable routing table," on page 87), 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" on page 46).
3. Group the cables together and position them safely away from the switch to avoid damage during the
chassis replacement process.

Remove the old switch chassis and install the new switch chassis

About this task
Follow these steps to remove the switch chassis from the cabinet. The rack mount hardware from the old
chassis will be used for installing the new chassis in the cabinet. Depending on how the switch chassis
was installed, you will need to complete the appropriate instructions in reverse to remove the chassis
from the cabinet and the rack mounting kit hardware from the old chassis. Then complete the
appropriate instructions from the beginning to attach the rack mounting kit hardware to the new chassis
and install it into the cabinet. Refer to "Mounting the switch" on page 13 for more information.
Procedure
Complete these steps after the new chassis is installed in the cabinet.
1. Reconnect all transceivers and fiber cables, using the information recorded in Table 19 on page 87 to
ensure that connections are made to the correct ports.
2. Connect the two power cables to the power sources. The switch will begin to power up and start the
POST as soon as the first power cable is connected.
3. Once POST has completed, the switch is ready to restore the saved configurations. Refer to the Fabric
OS Command Reference for more information on the CLI commands.
