Getting Started The High Availability function allows you to connect two Firewalls
together as a pair. Although only one Firewall will function at a time the
second will automatically take over from the first in the event of a failure.
Before attempting to configure two Firewalls as a High Availability pair,
check the following requirements:
■
You have two Superstack 3 Firewalls available. The Firewalls must be
running the same version of firmware which must be version 6.0 or
above.
The 3Com Firewalls 3CR16110-95 and 3CR16110-97 use identical
hardware and can be used as a high availability pair provided that they
are using the same version of firmware.
