Boot Banks and Bootloader Settings
Key
A key for validating the firmware file. The key is provided with the firmware file
(32 hex characters).
Load Firmware Via
From the drop-down list, select the method of loading the firmware. Options are
FTP, TFTP, HTTPS, NFS, USB, and SD Card. FTP is the default.
If you select HTTPS, the Upload File link becomes active. Select the link to
open a popup window that allows you to browse to a firmware update file to
upload.
If you select NFS, the mount directory must be specified.
The SD Card option must be selected if an SD card is to be used.
Note: Connections available depend on the model of the SLC unit.
Bank 1
Displays the version of SLC firmware in bank 1.
Note: The word "current" displays next to the bank from which the SLC
booted.
Bank 2
Displays the version of SLC firmware in bank 2.
Next Boot Bank
Displays the current setting for bank to boot from at next reboot.
Switch to Bank 2
If desired, select the alternate bank to boot from at next reboot.
Copy configuration
from Bank 1 to Bank 2
during firmware update
If checked, will copy the configuration from the current bank to the bank being
updated. The two numbers are automatically generated so that the first
number is the current bank.
Boot Count, Boot Delay,
Boot Limit
Parameters that control how the SLC boots and when it switches to the
alternate boot bank.
Boot Delay - how many seconds the bootloader pauses before booting the
SLC. Default is 3 seconds, range is 3 - 1800 seconds.
Boot Limit - how many times the SLC will fail to boot before switching to the
alternate boot bank. After the SLC fails to boot 2 times Boot limit (so it has
attempted to boot Boot Limit times on each bank), the SLC will go into
advanced recovery mode, which may require support from Technical
Support to resolve so that the SLC can be booted again. Default is 3 boots,
range is 3 - 20.
Boot Count - how many times the SLC has failed to boot. If this value
reaches Boot Limit, the SLC will switch to the alternate boot bank. The SLC
will switch to the alternate boot bank only once. For example, if it fails to
boot Boot Limit times on bank 1, it will automatically switch to bank 2; if it
fails to boot Boot Limit times on bank 2, it will enter advanced recovery
mode. If Boot Count has reached Boot Limit, setting this value to 0 will
enable the SLC to boot again. Default is 0, range is 0 - 1.
High Resolution Timers Enables or disables timers with a high degree of accuracy. High resolution
timers are required for Performance Monitoring, but may affect SLC
performance if they are enabled. Off by default. Changing this value requires a
reboot for the change to take effect.
Watchdog Timer Timer that will reboot the SLC if the boot fails to properly complete. If the timer
expires without a successful boot of the SLC, the timer will automatically reboot
the SLC. The default is 300 seconds. A value of zero will disable the watchdog
timer.
