General

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.

Low

Sets the acceptable low range for the internal temperature of the SLC or SLB unit. If the temperature of the SLC or SLB device changes to be outside of this range, the SLC or SLB unit will issue an SNMP trap.

High

Sets the acceptable high range for the internal temperature of the SLC or SLB unit. If the temperature of the device changes to be outside of this range, the SLC or SLB unit will issue an SNMP trap.

Calibrate Offset

An offset for calibrating the internal temperature of the SLC or SLB unit. The offset will be applied one hour after setting the calibration value. Zeroing the offset will take effect immediately and will cancel any current and/or pending calibration.

Data Center
Rack Row

Set these fields to define where the SLC or SLB unit is located within a large data center. The default for these fields is 1.

Rack Center Rack Cluster

Set these fields to define where the SLC or SLB unit is located within a large data center. The default for these fields is 1.

Data Center Rack

Set these fields to define where the SLC or SLB unit is located within a large data center. The default for these fields is 1.

SLC/SLB Firmware

Update Firmware

To update the  SLC or SLB firmware, select the checkbox. If you select this option, the  SLC or SLB unit reboots after you apply the update.

To view a log of all prior firmware updates, click the Firmware Update Log link.

Note: For dual boot  SLC or SLB units, the non-active boot bank is updated during the firmware update, without requiring a reboot. The configuration on the current boot bank may optionally be copied to the non-active boot bank during the firmware update. For both single boot and dual boot  SLC or SLB units, prior to firmware update, the current configuration is saved to the Local Disk location with the name "before_MMDDYY_HHMM".

Firmware Filename

The name of the firmware update file that you have downloaded from the Lantronix web site.

Key

A key (32 hex characters) for validating the firmware file.  The key is provided with the firmware file.

Load Firmware Via

From the drop-down list, select the method of loading the firmware. Options are FTP, SFTP, TFTP, HTTP, NFS, USB and PC Card.  FTP is the default. For NFS, the mount directory must be specified. For PC Card, the slot must be selected. Connections available depend on the model of the SLB or SLC unit.

Load Firmware Via Options

Configuration Management

Configuration Management

 

From the option list, select one of the following:

No Save/Restore:  Does not save or restore a configuration.

Restore Factory Defaults:  Restores factory defaults. If you select this option, the SLC or SLB unit reboots after you apply the update. Select the SSH Keys checkbox to save any imported or exported SSH keys. Select the SSL Certificate checkbox to save an imported certificate. Select the Scripts checkbox to save any interface or batch scripts. Disabled by default.

Restore Saved Configuration:  Returns the SLC or SLB settings to a previously saved configuration.  If you select this option, the SLC or SLB device reboots after you apply the update.

Save Configuration:  Saves all settings to file, which can be backed up to a location that is not on the SLC or SLB unit.

Configuration Name to Save to or Restore From

If you selected to save or restore a configuration, enter a name for the configuration file (up to 12 characters).

Location for Save, Restore, or Manage

If you selected to save or restore a configuration, select one of the following options:

Local Disk – Saved Configurations:  If restoring, from the drop-down list, select a saved configuration.

FTP Server:  The FTP server specified above.

NFS Mounted Directory:  Path of the NFS server for mounting files.

CIFS Share – Saved Configurations:  If restoring, select a saved configuration from the drop-down list.

PC Card:  If a PC Card Compact Flash is loaded into one of the PC card slots of the SLC or SLB unit, and properly mounted,  the configuration can be saved to or restored from this location.  PC card slots are available for certain models of SLC and SLB units.

If you select this option, select the slot in which the PC card compact flash is mounted; then click a saved configuration from the drop-down list.

USB:  If a USB is loaded into the SLC or SLB unit,  the configuration can be saved to or restored from this location.  USB port(s) are available for certain models of SLC and SLB units.

HTTPS:  For saving, the browser will prompt the user to save the configuration. For restoring, the configuration will be uploaded to the Local Disk location.

Manage:  This option allows you to view and delete all configurations saved to the selected location. This feature is available for the Local Disk, NFS Mounts, CIFS Share, and PC Card locations.

Note:  If you selected an option that forces a reboot (restore configuration, update firmware, or reset factory defaults), the SLC or SLB unit automatically reboots at the end of the process.

 

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:

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.
