Installing and Removing SFP Modules
–
In the
Telnet Password
field, enter a password. The Telnet password can be from 1 to 25
alphanumeric characters, is case sensitive, allows embedded spaces, but does not allow spaces
at the beginning or end. In the
Confirm Telnet Password
field, re-enter the Telnet password.
–
In the
SNMP
field, click
Enable
to enable Simple Network Management Protocol (SNMP).
Enable SNMP only if you plan to manage the switch modules by using CiscoWorks 2000 or
another SNMP-based network-management system.
–
If you enable SNMP, you must enter a community string in the
SNMP Read Community
field,
the
SNMP Write Community
field, or both. SNMP community strings authenticate access to
MIB objects. Embedded spaces are not allowed in SNMP community strings. When you set the
SNMP read community, you can access SNMP information, but you cannot modify it. When
you set the SNMP write community, you can both access and modify SNMP information.
Step 3
Click

to save your settings, or click
Cancel
to clear your settings.
When you click
Submit
, the switch module is configured and exits Express Setup mode. The PC displays
a warning message and then attempts to connect with the new switch module IP address. If you
configured the switch module with an IP address that is in a different subnet from the PC, connectivity
between the PC and the switch module is lost.
Step 4
Disconnect the switch module from the PC, and install the switch module in your network. See the
“Management Options” section on page 1-6
for information about configuring and managing the switch
module.
If you need to rerun Express Setup, see the
“Running Express Setup” section on page 2-9
.
To install additional switch modules, repeat the steps in the
“Installing the Switch Module in the Blade
Server” section on page 2-6
through the
“Running Express Setup” section on page 2-9
.
Refreshing the PC IP Address
After you complete Express Setup, you should refresh the PC IP address:
•
For a dynamically assigned IP address, disconnect the PC from the switch module, and reconnect
the PC to the network. The network DHCP server assigns a new IP address to the PC.
•
For a statically assigned IP address, change it to the previously configured IP address.
Installing and Removing SFP Modules
These sections describe how to install and remove SFP modules. The modules are inserted into the
SFP module slots on the front of the switch module. These field-replaceable modules provide uplink
interfaces.
You can use any combination of SFP modules. Refer to the switch module release notes for the list of
SFP modules that the switch module supports. Each port must match the wave-length specifications on
the other end of the cable, and the cable must not exceed the stipulated cable length for reliable
communications. See the
“Installation Guidelines” section on page 2-3
for cable stipulations for
SFP connections.
