Role
Role of Master and Backup is
configurable. Master takes over
from Backup if the Master goes
down and then becomes the
Master again if it comes back
online again (failback).
Role of active and passive is not configurable. The active
model is the one whose heartbeat interface comes online
first. The passive becomes active if active goes down and
stays active even if the previous active comes online again.
Firmware
Upgrade
Master remains Master by default
when new firmware is uploaded.
If Device HA Pro is enabled, then both the active and
passive Zyxel Device must be online and connected in
order to upload firmware. New firmware is first uploaded to
the passive device and then uploaded to the active
device. By default, the passive device reboots after
firmware upload making it become the active device.
Don’t select the
Reboot
prompt after uploading firmware to
the passive device if you want the passive device to remain
passive when new firmware is uploaded. Alternatively,
disable Device HA Pro if you want to just upload firmware to
the active Zyxel Device.
