Power-down procedure

Use the following procedure to power down the chassis and replace both CP blades. You can replace a single CP blade using the power-
up procedures.
1. Remove the chassis door.
2. If you haven't already done so, enter configupload - all, specifying a file name for saving configuration data.
This saves all system configuration data including chassis and switch configuration for all logical switches to the file name
specified. For more information, refer to the Brocade Fabric OS Command Reference.
3. If you haven't already done so, enter configupload -vf, specifying a file name for saving configuration data.
This saves the backbone virtual fabric data to the file name specified. For more information, refer to the Brocade Fabric OS
Command Reference.
4. If you haven't already done so, enter configupload -map, specifying a folder name.
This command saves the port-to-area addressing mode configuration files to the folder specified. With Fabric OS 7.4.0, you
need to upload the configuration with -map option in a FICON-enabled DCX 8510 chassis if port-bound addressing is used.
For more information, refer to the Brocade Fabric OS Command Reference.
5. Power down the chassis.

a) Disconnect all cables from the blades.
b) Unscrew the thumbscrew from both ejectors for a blade using the Phillips screwdriver.
c) Lever open both ejector handles simultaneously to approximately 45 degrees and pull the CP blade out of the chassis.
7. Replace the blades using the following steps:
a) Open the ejector handles to approximately 45 degrees. Orient the CP blade so that the handles are toward you.
b) Align the flat metal side of the CP blade inside the blade guides in the slot. Slide the CP blade into the slot until it is firmly
seated.
c) Tighten the thumbscrew inside each handle using the Phillips screwdriver.
