Known issues

VSIS-149 Upgrading INCA stations might fail in some very rare cases

In case station is not upgraded, simply run upgrade on failed stations again. In more severe cases, restarting station to factory defaults is necessary to make upgrade possible.

MTN-1112 Image upgrade does not work with 802.1x authentication enabled in switch

  • Remove security on the switch-port, upgrade and set security back on the switch port.
  • Un-mount the station, connect it to a non-802.1x port and do a manual upgrade.
The reason for this is that during upgrade of the IP-station, 802.1X will not be running after first Ethernet link down/up and image download start.

MTN-1052 PTT does not work between Gateway and INCA station
