Using Device Manager for the SAM

Troubleshooting the opening of a device

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

To troubleshoot opening a device:

• 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 strings.
• If you cannot reach the switch through an IP address or the management station cannot communicate with the switch, check the following:

­	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?
