IP Configuration Errors

IP Configuration Errors

If you are using IP communications, make sure your IP configuration param- eters are set properly. Use the switch console’s IP Configuration function as described in chapter 4. Incorrect IP configuration on the Switch Management Module will prevent it from communicating with the network management station, and may cause other network problems.

In particular, make sure you provide the Switch Management Module with a unique IP address, and that you use the correct subnet mask for your network.

Diagnostic Tests

The HP AdvanceStack Assistant and switch console provide tests and indica- tors that can be used to monitor the switch and its network connections.

Testing the Switch and Management Module

If you believe that the switch or its Management Module are not operating correctly, remove and reinsert the power cord for that switch. This procedure causes the switch and module to complete their power-on self test.

Normally, when the self test completes, the module’s Self Test LED and all Fault LEDs on the switch and module will go OFF. If any error conditions exist in the switch or the module, the LEDs should display the condition. See the HP AdvanceStack Switch 208/224 Installation and Reference Guide to interpret the LED display for the switch. For the module, see the table under “Checking the Module LEDs” at the beginning of this chapter.
