6-3

To remove the CPU module, do the following:

1.

Determine the firmware version. Open a Telnet session and enter the Show 
Version command to determine the current firmware version. Make note of 
the firmware version. If the switch is inaccessible, you can obtain the 
firmware version from another switch in the fabric or records you may have 
kept. Refer to 

 for more information.

2.

Configure the Telnet window to log output to a file. Enter the Show Support 
command to document the switch and capture the output on a file.

3.

Back up the switch configuration. Enter the Config Backup command to 
back up the switch configuration to a file on the switch named configdata. 
You can also back up the switch configuration using the Archive function in 
the SANbox Manager application. Refer to the SANbox2-64 Switch 
Management User’s Guide for more information.

4.

Back up the event log. Enter the Set Log Archive command to back up the 
event log to a file on the switch named logfile.

5.

Download the configuration and log files to your workstation. Open an FTP 
session to download the configdata and logfile files onto your workstation. 
Later, you will restore the switch configuration using the configdata file.

6.

Power down the switch. Open a Telnet session and enter the Shutdown 
command then disconnect the power cords from the power supplies.

7.

Label and disconnect the Fibre Channel port cables. This will avoid 
compromising security and prevent data corruption when the switch is 
powered up with the new CPU module. Label I/O blades by slot number. I/O 
blade slots are numbered 1–4 and 6–9. Label Fibre Channel port cables by 
slot number and port number. Ports on each I/O blade are numbered 0–7 
from top to bottom.
