Troubleshooting
Symptom Possible causes
The PoE access point, switch, or other powered
device will not turn on. •
Try changing the PoE mode to “forced on”
from the interfaces menu. Remember, never
force PoE on a non-PoE device!
•
Select the appropriate voltage when setting
the power to “forced on”. 802.3af/ at devices
will require “high” voltage.
I can’t get VLANs to work correctly. •
The router must be configured to work with
VLANs for most operations.
•
Ensure the trunk ports are tagged correctly.
•
Contact CIS for assistance.
I can’t get a connection when using the SFP port. •
CIS recommends DAC SFP cables such as the
CIS-SFP-001 and 003, though other SFP
modules are compatible.
•
Try a different SFP port. Two ports are set at
10 Gbit and the other two are set at 1 Gbit to
maximize compatibility.
•
Ensure the SFP cables are inserted completely.
There should be a slight click as they are
inserted. They will slide in most of the way
when upside down but will not fit completely.
•
Check the interface status. Click Interfaces,
then the Ethernet tab. Click on the SFP port in
question. Determine if it is passing traffic.
Consider disabling auto negotiation and
setting the speed and duplex manually.
I can’t enable IGMP Snooping , etc. •
