FAN unit disconnection

Step 1
- Remote fan unit power off ?
Check the remote fan unit is power ON or not.

Check and make sure fan unit level is unique and not duplicated in the same
Master IP group.
( Please refer to user manual < 2.5 > for the fan unit level setting )
2. GUI shows from a certain level remote fan unit to the last one disconnected
(Except Master IP fan unit)
Step 1 - Cable disconnected, loose or defective ?
Check the Cat. 5 / 6 cable connection between remote fan units. Make sure the
connectors are fi rmly attached. And check if any defects on your cables or not.
If yes, replace a new one.
Step 2
- The fi rst disconnected remote fan unit failed ?
Unplug the Cat. 5 / 6 cable on the fi rst disconnected remote fan unit, then plug it
to the second disconnected remote fan unit to check if the problem caused by
the fi rst disconnected remote fan unit.
3. GUI shows the whole group of remote fan unit(s) disconnected
Step 1
- Cable disconnected, loose or defective ?
Check the Cat. 5 / 6 cable connection to remote fan units and network devices.
Make sure the connectors are fi rmly attached. And check if any defects on your
cable or not. If yes, replace a new one.
Step 2
- Master IP fan unit failed ?
i. Check if the network setting of the Master IP fan unit is correct or not.
If duplicate IP address is in the network, it may cause such problem.
ii. Disconnect the Master IP fan unit from the network and try to direct connect
the Cat. 5 / 6 cable from the <IP> port to a computer network port and use
IP Setup utilities to check if the Master IP fan unit can be found or not.
If it cannot be found, the Master IP fan unit may be failed.
