Symptom

Solution
Power LED is off.
No power is received.
• 
Check the power cord connections at the 
smart switch and the power source.
• 
Ensure that all cables are used correctly and 
comply with the Ethernet specifications.
Combined Link, Speed, 
Activity LED is off when 
the port is connected to 
a device.
Port connection is not working.
• 
Check the crimp on the connectors and 
make sure that the plug is properly inserted 
and locked into the port at both the smart 
switch and the connecting device.
• 
Ensure that all cables are used correctly and 
comply with the Ethernet specifications. 
• 
Check for a defective port, cable, or module 
by testing them in an alternate environment 
where all products are functioning.
File transfer is slow or 
performance is 
degraded.
Half-duplex or full-duplex setting on 
the smart switch and the connected 
device are not the same.
Make sure that the attached device is configured 
to autonegotiate.
A segment or device is 
not recognized as part 
of the network.
One or more devices are not 
properly connected, or cabling does 
not meet Ethernet guidelines.
• 
Verify that the cabling is correct. 
• 
Ensure that all connectors are securely 
positioned in the required ports. It is possible 
that equipment was accidentally 
disconnected.
Combined Link, Speed, 
Activity LED is blinking 
continuously on all 
connected ports and 
the network is disabled.
A network loop (redundant path) 
was created.
Break the loop by ensuring that only one path 
exists from any networked device to any other 
networked device. After you connect to the smart 
switch web management interface, you can 
configure the Spanning Tree Protocol (STP) to 
prevent network loops.
A unit is linked to a 
stack but does not join 
the stack.
The stacking ports of the new unit 
are configured differently from the 
stack, or the unit is configured as a 
standalone unit.
Remove the unit from the stack. Use the web 
management interface to configure the unit as a 
stackable unit, with combo links used as the 
stacking ports.
