Table A-4. Troubleshooting Chart

Symptom Cause Solution

Power LED is off. No power is received. Check the power cord connections and the connected

device. Ensure that all cables used are correct and

comply with Ethernet specifications.

Link LED is off or

intermittent.

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 switch and the connecting device. Ensure that

all cables used are correct and comply with Ethernet

specifications. Check for a defective computer 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-duplex or full-duplex

setting on the switch and

the connected device are

not the same.

Make sure that the attached device is set 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. Equipment might have been accidentally

disconnected.

ACT LED is blinking

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. After you connect to the switch management

interface, you can configure the Spanning Tree

Protocol (STP) to prevent network loops.
