CAUTION:
If it is necessary to replace both the chassis and the SP module, do not replace at the same time.
Important configuration information can be lost. In this instance, you must do a serial swap in which the SP
module is replaced first, the system is booted, the system is brought down, and then the chassis is replaced.
Shut down and disconnect the system
Steps
1. Stop the system using the system poweroff command to allow the proper shut down of the file system and other system
components.
NOTE:
The system poweroff command completes when the front panel blue LED turns off.
For help connecting to a system using a laptop computer and terminal emulator, see the document F
E Toolkit Inventory and
Common Procedures for FRU Tasks at https://support.emc.com.
2. Label each of the cables as to their connection location. Taking a photograph for reference is also helpful for re-connecting
the cables.
3. Disengage the wire clips, then disconnect both AC power cords from the rear of the system.
