Troubleshooting the opening of a switch

If the switch does not open, Device Manager displays a timeout message.

To troubleshoot opening a switch:

• In slower networks, increase the retransmission retries and timeout interval.
• In the Open Device dialog box, make sure you entered the correct read and write community information.
• If you cannot reach the switch through an IP address or the management station cannot communicate with the switch, check the following possibilities:

- Is the switch connected to the network?

- Is the switch turned on?

- Does the switch have an incorrect IP address?

- Is the incorrect IP address specified in the Open Device field in Device Manager?

- Is the network misconfigured?
