ROUBLESHOOTING

Cannot connect using 

Telnet, web browser, 

or SNMP software

• Be sure the switch is powered up.
• Check network cabling between the management station 

and the switch.

• Check that you have a valid network connection to the 

switch and that the port you are using has not been disabled.

• Be sure you have configured the VLAN interface through 

which the management station is connected with a valid IP 
address, subnet mask and default gateway.

• Be sure the management station has an IP address in the 

same subnet as the switch’s IP interface to which it is 
connected.

• If you are trying to connect to the switch via the IP address 

for a tagged VLAN group, your management station, and 
the ports connecting intermediate switches in the network, 
must be configured with the appropriate tag. 

• If you cannot connect using Telnet, you may have exceeded 

the maximum number of concurrent Telnet/SSH sessions 
permitted. Try connecting again at a later time.
