CMOB Operation Issues

• Client Computer can not connect to a CMOB-enabled SSID
— The PXU profile should have at least one PXU Module (Primary/Secondary) enabled
— The AP should be registered with the PXU Module
— The PXU Module (that the AP is registered with) should be registered with the Current Master PXU Module.
Refer to the ProximUnify User Guide for more details.
• AP does not register with the PXU
— The AP's "Domain Name" and "Shared Secret" should match the "Domain Name" and "Domain Password"
configured on the PXU Module.
— The PXU profile should have at least one PXU Module (Primary/Secondary) enabled.
— Management VLAN ID of the PXU module and the AP must be the same.
— VLAN status of the PXU module and AP must be enabled.
— AP must have a CMOB enabled SSID tagged to the proper VLAN ID configured in the uplink table.
• AP gets de-registered from the PXU and re-registers for no apparent reason, OR it ping-pongs between Primary
and Secondary PXU Modules.
— If MESH backhaul is being used, RF Interference may cause packet loss or connectivity loss resulting in this
scenario.
— If there is traffic congestion in the network segments connecting the AP with the PXU, refer to the PXU User
Guide for making configuration changes to mitigate this scenario.
• Client Computer associates and connects but can not ping some other computer: refer to the PXU User Guide for
more details.

Power-Over-Ethernet (PoE)

The AP Does Not Work
1. Verify that you are using a standard UTP Category 5 cable.
2. Try a different port on the same PoE hub (remember to move the input port accordingly) – if it works, there is probably
a faulty port or bad RJ-45 port connection.
3. If possible, try to connect the AP to a different PoE hub.
4. Try using a different Ethernet cable – if it works, there is probably a faulty connection over the long cable, or a bad
RJ-45 connection.
5. Check power plug and hub.
6. If the Ethernet link goes down, check the cable, cable type, switch, and hub.
There Is No Data Link
1. Verify that the indicator for the port is "on."
2. Verify that the PoE hub is connected to the Ethernet network with a good connection.
3. Verify that the Ethernet cable is Category 5 or better and is less than 100 meters (approximately 325 feet) in length
from the Ethernet source to the AP.
4. Try to connect a different device to the same port on the PoE hub – if it works and a link is established, there is
probably a faulty data link in the AP.
5. Try to re-connect the AP to a different output port (remember to move the input port accordingly) – if it works, there is
probably a faulty output or input port in the PoE hub or a bad RJ-45 connection.
