Removing and Replacing the SilkWorm 4016
To remove a failed or replaced SilkWorm 4016:
1. Back up the switch configuration to an FTP server by typing the configUpload command and
following the prompts.
This command uploads the switch configuration to the server, making it available for downloading
to a replacement switch if necessary. Brocade recommends backing up the configuration on a
regular basis to ensure that a complete configuration is available for downloading to a replacement
switch.
2. Stop all SAN activity requiring the ports used by the SilkWorm 4016.
For details about port management, refer to your blade server documentation. Verify that there is no
activity by viewing the SilkWorm 4016 LEDs. For details about LED activity on the SilkWorm
4016, see “Interpreting LED Activity” on page 4-4.
3. Remove all cables from the SFP modules.
4. Remove the SFP modules according to the manufacturer’s instructions.
