Committing a
New Software
Load
/system/commit load
Once you have activated the unit with new software load, you can commit it
with this command. See
CAUTION!
This command copies the contents of the active software bank to the standby
bank. For example, if the active software bank is A, its contents overwrite those
of bank B. Backing out is no longer possible after the new software load has
been committed. After the new software load has been committed, you can no
longer back out of the upgrade; but you can downgrade the unit. For
instructions on how to downgrade a unit, contact BelAir Networks.
