As of HiPath 4000 V4, this feature is supported for all common gateway boards.
Regardless of the boards configuration as single feature mode or as multiple
feature support (MFS).

This feature is designed to increase the availability of IP terminals, IP trunking

HFA infrastructure
This is achieved through the introduction of a standby board. In the event of a
board or LAN cable defect, standby boards can inherit the IP stations or IP
trunking lines, etc. assigned to an active board. If appropriately configured, this
action can be performed automatically, that is, without manual intervention or use
of AMO commands. This is illustrated in the following example which depicts a
common gateway with HFA stations.
In the example in Figure 18 HFA infrastructure, the standby board is the HG 3500-
3. If, for example, an HG 3500-1 fails, the IP Phone 2160 will be reconfigured to
HG 3500-3 and goes into operation with the new board.
Provided this feature was preconfigured (see below), automatic switchover takes
place in the following events:
•
When the board is removed without prior deactivation
