Netgear GS752TXS - Stackable Smart Gigabit Ethernet Switch 관리자 가이드

Troubleshooting Chart

The following table lists symptoms, causes, and solutions of possible problems.

Power LED is off.

No power is received.

Check the power cord connections for 
the switch at the switch and the 
connected AC power source.

Link/ACT LED is off 
when a cable 
connects the port to 
a valid device.

Port connection is not working.

•

Check the crimp on the 
connectors, and make sure that 
the plug is correctly inserted and 
locked into the port at both the 
switch and the connecting device. 

•

Ensure that all cables are used 
correctly and comply with the 
Ethernet specifications.

•

Check for a defective adapter 
card, cable, or port by testing 
them in an alternate environment 
where all products are 
functioning.

File transfer is slow, 
or performance 
degradation is a 
problem.

Half- or full-duplex setting on the 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 connected 
correctly, or cabling does not meet 
Ethernet guidelines.

Verify that the cabling is correct. 
Ensure that all connectors are 
securely positioned in the required 
ports. Equipment could have been 
accidentally disconnected.

Link/ACT LED is 
flashing continuously 
on all connected 
ports, and the 
network is disabled.

A network loop (redundant path) has 
been created.

Break the loop by ensuring that there 
is only one path from any networked 
device to any other networked device.
