Start-up Problems

I’ve forgotten my password

Explanation: You are prompted for a password on the Login screen.

Action: Enter Maintenance Mode, and type: run defparm.

Consequence: This resets the conﬁguration to the default values so you can assign a new password.

When I make changes to the switch’s conﬁguration, they take effect but as soon as the switch is powered off and on again the changes are lost

Explanation: When you change the switch’s conﬁguration, you are changing the current active conﬁguration that is running in RAM. However, every time the switch starts up it loads the conﬁguration that is stored in its ﬂash memory. Therefore, if you make a change to the conﬁguration and want to keep it, you need to save the new conﬁguration to the switch’s ﬂash memory.

Action: Save the conﬁguration changes to ﬂash memory.

To check the status of the configuration, select Configura- tion>Software.

Performance Problems

One or more workstations cannot communicate with a server or other device through the switch

Explanation: This symptom might be noticed on one or more seg- ments connected to the switch, and could be caused by cable faults, inappropriate conﬁguration or faulty installation.

Action: Check all connections and verify your conﬁguration. Check any error counters for the ports.

The 100Mbps ports are not working, or work very poorly

Explanation: This is probably due to incorrect conﬁguration of the auto-negotiation duplex settings and link speeds.

Action: Check the negotiated settings in the switch and compare them to the expected values.
