THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE
OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following inform ation is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

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.
This chapter provides a functional overview of the switch modules and covers these topics:
• Switch Modules, page 1-1
• Hardware Features, page 1-2
• Management Options, page 1-9

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
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.”

Hardware Features
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
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.”

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.
Management Options
Table 1-11 lists the LED colors and their meanings.
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
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.
Figure 1-1). Use the supplied USB-to-DB-9 cable to connect the switch module
OL-12192-01
• 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.
