In addition, if the N5500 is able to access the Internet and you want to keep the NTP

Network > WAN > DNS Server)
Dual DOM Supports for Dual Protection
The most advance and useful of N5500 is Dual DOM implemented. In the normal
circumstance, it has no need to have this feature involved. But with irresistible
cause like power cut or human error by accident occurred especially during system
booting stage, this will become the great feature to prevent system down time.
Practically while it happened, system will try to recovery the DOM 1 from DOM 2 first.
If it is unachievable then system can boot from DOM 2. And all of this procedure can
be operated by LCM.
NOTE
The Dual DOM in DOM1 is default master and FW upgrading will only
execute in DOM1 unlike DOM2 is ‘Read only” initially.
Any circumstance occurred, while DOM2 successes recover DOM1. The
FW will be version of DOM2. Therefore, it may need to upgrade to the
version of DOM1 it has.
If DOM1 can not be recovery from DOM2, then system will boot up from
DOM2. The original configuration in DOM1 may need to setup again with
DOM2 operation.
