Problem Possible Cause Possible Solution
The interconnect switch is not
connected properly to the network.
Check the cable and connections and make
sure there is network connectivity between the
interconnect switch and the DHCP server.
The DHCP server is not available on
the network or VLAN that is attached
to the switch management port.
Make sure DHCP server is present on the
network or VLAN attached to the interconnect
switch.
The DHCP server is not able to offer
IP settings to the interconnect switch
as it is out of available IP addresses.
Make sure the IP addresses are available.
The interconnect switch
fails to get its IP settings
from DHCP server, even
though by default it is
configured for DHCP.
NOTE: If you are running
in spanning tree mode, it
can take 60-90 seconds
for the switch module to
get its IP settings.
The interconnect switch timed out its
request for IP settings.
• Go to the Switch IP Settings screen and
click Apply, to make the interconnect
switch retry DHCP.
• Reset/reboot the interconnect switch.
The interconnect switch IP address
may not be configured or correct.
• From the serial console interface, on the
Switch IP Settings screen, make sure
that the interconnect switch IP address is
configured and valid on your network.
• Use the correct IP address to establish the
Telnet connection with the interconnect
switch.
The setting allowing access to the
interconnect switch using the Telnet
interface is disabled.
From the serial console interface, on the
Advanced Switch Settings screen, make
sure the Telnet interface is enabled.
The Security IP list (if used) does not
contain the IP address of your
management station.
From the SNMP Manager Configuration
screen, make sure that security IP list or
Management IP Station list has the IP address
of your management station.
Cannot connect to the
interconnect switch
console interface remotely
using Telnet.
The internal switch processor port
(meant for supporting switch
management interfaces) and the port
to which you have connected to
access the switch from the Telnet,
Web, or SNMP interfaces are not in
the same VLAN.
Make sure that the Management VLAN ID on
the Switch IP Settings screen is the same as
the VLAN ID of the port that is trying to make
the Telnet, Web, or SNMP connection. If not,
change it to match.
