tion can no longer access the device:
Check that Remote Telnet access or Commu-
nity-SNMP access is enabled.

access the device has not been disabled; refer to
“Setting Up the Switch Ports” on page 4-12. If it is
enabled, check the connections and network cabling
at the port.
Check that the port through which you are trying to
access the device is in VLAN 1 (the Default VLAN).
