OLVING

The SNMP network management application 
cannot access the stack. Check that:

■

The switch’s IP address, subnet mask and default 
router are correctly configured and that the switch 
has been reset since configuring this information; 
refer to 

■

The switch’s IP address is correctly recorded by the 
SNMP management application. For information on 
how to do this, refer to the documentation 
accompanying the application.

The SNMP network management application can 
no longer access the switch. Check that the port 
through which you are trying to access the switch has 
not been disabled. If it is enabled, check the 
connections and network cabling at the port. Try 
accessing the switch through a different port. If you 
can now access the switch, a problem with the 
original port is indicated. Re-examine the connections 
and cabling.

Possibly there is a network problem preventing you 
from accessing the switch over the network. Try 
accessing the switch through its console port and 
reset the switch.
