Switch Module Ip Addresses; Running Express Setup - Cisco Catalyst 3020 Getting Started Manual

Step 6 Push the release latch on the front of the switch module to the closed position.

Switch Module IP Addresses

IP addresses can be assigned to two of the switch module interfaces:
• The fa0 Ethernet interface. This Layer 3 Ethernet interface is connected to the Onboard
Administrator through which you can manage the switch module. It is used only for switch
module management traffic, not for data traffic.
• The VLAN 1 interface. You can manage the switch module from any of its external ports through
VLAN 1.
If you want to assign the VLAN 1 IP address through Express Setup, you must start that process
immediately after installing the switch module in the blade server. If you miss the opportunity to have
the IP address assigned in this way, you can remove and then re-install the switch module. See the
"Running Express Setup" section on page 9 for instructions.
When you install the switch module, you need to determine whether the Onboard Administrator is
connected to a network in which a DHCP server is also connected or if the Onboard Administrator
has been configured as a DHCP server. If either of these conditions is true, the switch module
automatically obtains an IP address for its fa0 Ethernet interface that is connected to the Onboard
Administrator. In this case, a VLAN 1 IP address is not assigned, and to set up the switch module by
using the Device Manager you must use the fa0 interface IP address that the DHCP server assigns.
See the "Using the Onboard Administrator to Assign an IP Address to the Switch Module fa0
Interface" section on page 14 for how to set up the switch module if the IP address is being assigned
dynamically.
