The Firmware & Configuration page allows the system administrator to:
Configure the FTP, SFTP, or TFTP server that will be used to provide firmware updates and save/restore configurations. (TFTP is only used for firmware updates and configurations restored via DHCP/TFTP Zero Touch Provisioning.)
Set up the location or method that will be used to save or restore configurations (Local Disk, FTP, SFTP, NFS, CIFS, or PC Card). Update the version of the firmware running on the SLC or SLB unit.
Save a snapshot of all settings on the SLC or SLB device (save a configuration).
Restore the configuration, either to a previously saved configuration, or to the factory defaults.
For dual boot SLC or SLB units, view the firmware version on each boot bank, select the bank to boot from, and copy the contents of one boot bank to the other.
To configure firmware and configuration settings:
Complete or view the following sections:
Reboot |
To reboot the SLC or SLB unit immediately, select this option. This feature is unchecked by default. Note: The front panel LCD displays the "Rebooting the SLC" message and the normal boot sequence occurs. |
Shutdown |
Select this option to shut down the SLC or SLB unit. This feature is unchecked by default. |

Zero Touch Provisioning Configuration Restore
The Zero Touch Provisioning feature allows a factory defaulted SLC or SLB to acquire a default configuration from a DHCP server and TFTP server when it is booted. At boot-time, before the normal startup process, a unit will attempt to acquire network parameters and a configuration file, first over Eth1, and then over Eth2:
The unit will broadcast on the Eth1 network port for a DHCP server on the local subnet, requesting DHCP options "TFTP Server" (DHCP option #66) and "Boot Filename" (DHCP option #67).
If it receives both options from the DHCP server, and the Boot Filename is a valid SLC or SLB configuration filename ending in "-slccfg.tgz", it will attempt to download the Boot Filename from the TFTP Server.
If it is able to download the Boot Filename from the TFTP Server, it will restore the configuration onto the SLC, and begin the normal startup process.
If any of these steps fail for the Eth1 network port, it will repeat the process of trying to acquire a configuration over the Eth2 network port.
After attempting to acquire a configuration over the Eth2 network port, the unit will begin the normal startup process.
Any results of attempting to acquire and restore a configuration file will be output to the console port and the system log. Configurations for firmware versions that are newer than the firmware version running on the unit will not be restored. Spaces are not supported in either the directory or filename portion of the Boot Filename path.
