or SNMP software

• Be sure you have configured the agent with a valid

address, subnet mask and default gateway.

• If you are trying to connect to the agent via a tagged VLAN

group, your management station must include the

appropriate tag in its transmitted frames.

• Check that you have a valid network connection to the

switch and that the port you are using has not been

disabled.

• Check network cabling between the management station

and the switch.

• If you cannot connect using Telnet, there may already be

four active sessions. Try connecting again at a later time.

pin-out connections provided in the Installation Guide.
