Opening a Switch 11
Troubleshootingthe Opening of a Switch
Errors can occur during the opening of a switch. If an error occurs, ASEM
displays an error message. This message is illustrated in "Connection Error
Message" (page 11).
Connection Error Message
If this message is displayed, the following items should be checked:
•In slower networks, increase the Retry Count and Timeout values on
the Properties screen. See "Setting ASEM Properties" (page 5) for
information on performing this task.
•In the Open Device screen, ensure that the correct read and write
community strings have been entered for SNMP version 1 and 2
connections. See "Opening a Switch Using SNMP versions 1 or 2"
(page 8) for more information on performing this task.
•In the Open Device screen, ensure that the correct SNMP version 3
information has been entered for SNMP version 3 connections. See
"Opening a Switch using SNMPv3" (page 10) for more information on
performing this task.
•Ensure that the switch is physicallyconnected to the network.
•Ensure that the switch is turned on and receiving power.
•Ensure that the switch has been assigned a correct IP address.
•Ensure that the correct IP address is being used in the Open Device
screen.
•Ensure that the problem does not exist because of an unrelated network
misconfiguration.
•Ensure that SNMP access is enabled on the switch. Refer Nor tel
Application Switch Operating System 24.0 Command Reference
(NN47220-105) for information on enabling SNMP access.
•Ensure that switch is not blockingaccess from the client IP address.
