Replacing a CPU Module:

2.Unscrew the two thumb screws for the CPU module that you are replacing.

3.Using both hands pull on both thumb screws to slide the CPU module out of the 9000BP.

4.Align the new CPU Module such that it slides on the rails and firmly push it into the unit.

5.Screw both thumb screws down till they are finger tight.

6.Reapply the power to the switch.

NOTE: All configuration settings are saved to the NVRAM which is stored locally on the CPU Module. If you replace the CPU Module all settings will move with the CPU Module. You can save and download a custom configuration to a TFTP or an FTP server. The switch‟s MAC Address and IP Address will also move with the CPU Module.
