Product Overview
The Cisco Catalyst Switch Module 3110G, 3110X, and 3012 for IBM BladeCenter—referred to as the
switch modules—are Ethernet switch modules that you install in an IBM BladeCenter
enclosure—referred to as the blade enclosure. You can connect devices to the switch modules for
connections to other network devices such as routers, servers, and other switches.
The Catalyst Switch Module 3110G and 3110X support stacking through Cisco StackWise Plus
technology. The Catalyst Switch Module 3012 does not support stacking. Unless otherwise noted, the
term switch module refers to a standalone switch module and to a switch stack.
Note
This product is not intended to be connected directly or indirectly by any means whatsoever to interfaces
of public telecommunications networks.

10/100/1000 Ethernet Ports
The Catalyst Switch Module 3110G and 3012 10/100/1000 Ethernet ports use standard RJ-45 connectors
with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and
1000BASE-T traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP)
cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable.
For information about the 10/100/1000 Ethernet port connections and specifications, see the
“Connecting Devices to the Ethernet Ports” section on page 2-13 and Appendix B, “Connector and
Cable Specifications.”

10-Gigabit Ethernet Module Slot
The Catalyst Switch Module 3110X 10-Gigabit Ethernet module slot is used for an uplink connection to
other switches and routers. The module slot operates in full-duplex mode and uses the hot-swappable
Cisco X2 transceiver modules.
The X2 transceiver modules have a dual SC/PC connector (-SR, -LX4) or an Infiniband 4x connector
(-CX4) for connections to multimode fiber (MMF), single-mode fiber (SMF), or 4x Infiniband cable.
These are the supported Cisco X2 transceiver modules:
•
X2-10GB-SR
•
X2-10GB-CX4
•
X2-10GB-LX4
For information about installing a transceiver module, see the “Installing Devices in the 10-Gigabit
Ethernet Slot” section on page 2-11. For cable specifications, see Appendix B, “Connector and Cable
Specifications.”

1. The number of internal ports is determined by the blade enclosure model. See the blade enclosure documentation for more
information about internal port numbering.
Internal 100BASE-T Ethernet Management Port
The internal Ethernet management port (Fa0) is used only for switch module management traffic, not for
data traffic. It is connected to the IBM advanced Management Module (aMM) through the blade
enclosure backplane connector. Traffic to and from this port is isolated from the switch module ports.
This port only supports autonegotiation with 100 Mb/s and full-duplex mode.

StackWise Plus Ports
The switch module ships with a 1-meter StackWise Plus cable that you can use to connect the StackWise
Plus ports (only Catalyst Switch Module 3110G and 3110X).
Caution
Use only approved cables and connect only to Catalyst Switch Module 3110G and 3110X. Equipment
might be damaged if connected to nonapproved Cisco cables or equipment.
You can order these StackWise Plus cables from your supplier:
•
CAB-STK-E-0.5M= (0.5-meter cable)
•
CAB-STK-E-1M= (1-meter cable)
•
CAB-STK-E-3M= (3-meter cable)
Console Port
You can connect the switch module to a host such as a PC, workstation, or a terminal server through the
console port (shown in Figure 1-1). Use the supplied USB-to-DB-9 cable to connect the switch module
to a host.
For more information about the console port, see the switch module getting started guide, the software
configuration guide, and the command reference on Cisco.com.
Management Options
The switch module offers several management options:
•
Cisco IOS CLI
The switch module command-line interface (CLI) is based on Cisco IOS software and is enhanced
to support desktop-switching features. You can fully configure and monitor the switch module and
switch stack members from the CLI. You can access the CLI by connecting your management station
directly to the switch module console port or by using Telnet from a remote management station.
See the switch module getting started guide, the software configuration guide, and the command
reference on Cisco.com for more information.
•
BladeCenter Advanced Management Module
For standalone switch modules, you can use the aMM to configure the switch module. See the IBM
BladeCenter Advanced Management Module User’s Guide for more information. For stacked
switches, use the CLI to configure and manage the switch stack.

Management Options
•
IBM Director
For standalone switch modules, you can use the IBM Director to view the hardware configuration
of remote systems, monitor the usage and performance of critical components, centrally manage
individual or large groups of IBM and non-IBM Intel®-processor-based servers, desktop computers,
workstations, and mobile computers on a variety of platforms. See the IBM documentation for more
information.
•
Device manager
You can use the device manager, which is in the switch module memory, to manage standalone
switch modules and switch stacks. This web interface offers quick configuration and monitoring.
You can access the device manager from anywhere in your network through a web browser. For more
information, see the getting started guide and the device manager online help.
•
Cisco Network Assistant
Cisco Network Assistant is a PC-based network management GUI application optimized for LANs
of small and medium-sized businesses. Cisco Network Assistant offers centralized management of
Cisco switches ranging from the Catalyst Express 500 through the Cisco Catalyst 4506. Through a
GUI, users can configure and manage standalone switch modules and switch stacks. Cisco Network
Assistant is available at no cost and can be downloaded from this URL:
http://www.cisco.com/go/cna_doc
For information on starting the Network Assistant application, see the Getting Started with Cisco
Network Assistant guide on Cisco.com.
•
SNMP network management
You can manage switch modules from a SNMP-compatible management station. The switch module
supports a comprehensive set of Management Information Base (MIB) extensions and four Remote
Monitoring (RMON) groups. See the switch module software configuration guide on Cisco.com and
the documentation that came with your SNMP application for more information.
•
CiscoWorks application
The CiscoWorks device-management application displays the switch module image that you can use
to set configuration parameters and to view switch module status and performance information. The
CiscoView application, which you purchase separately, can be a standalone application or part of a
Simple Network Management Protocol (SNMP) platform. See the CiscoView documentation for
more information.
Network Configurations
See the switch module software configuration guide on Cisco.com for network configuration concepts
and examples of using the switch module to create dedicated network segments and interconnecting the
segments through Gigabit Ethernet connections.
