Identifying the Problem 131
The module status LED on the front
panel of the Switch flashes slowly
when the Layer 3 Module is
present. Switch software version in your
Switch does not support the Layer 3
Module. Upgrade the Switch software to a
version that supports the Layer 3
Module.
The software on the Switch must be
version 2.4 or later.
To determine the version of
software installed on the Switch, do
one of the following:
■
Use the Unit Status page on the
Web interface of the Switch.
■
Use the
system display
command on the Switch. The
software version is identical to
the Operational Version.
For further information, see your
Switch management guide.
Cannot contact any Layer 3 Module
IP address. Layer 3 Module is disabled on the
Switch. Use the
system module mode
command on the Switch to enable
the Layer 3 Module. You may have
to restart the Switch if you change
the enabled/disabled state of the
module.
Cannot ping or Telnet to the Layer
3 Module VLAN 1 IP address. Layer 3 Module has not finished
booting. The Layer 3 Module takes up to 90
seconds to start after the Switch has
been powered up. Check to see if
the module packet LED is blinking,
indicating that the module is
receiving packets from the network.
Layer 3 Module does not have a
VLAN 1 IP address. The Layer 3 Module must have a
VLAN 1 IP address. Define a VLAN 1
IP address on the Switch. The IP
address is then allocated to the
module each time the unit is
powered up. The Layer 3 module
VLAN 1 IP address must be on the
same network and subnet as the
Switch management IP address.
See step 3 on page 31 for more
information about setting IP
addresses on the Switch.
