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 information 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.

10/100/1000 Ethernet Ports

The 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
Category

5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category

3 or Category 4 UTP cable.

For more information about the 10/100/1000 Ethernet port connections and specifications, see the

“10/100/1000 Ethernet Port Connections” section on page 2-16 and Appendix B, “Connector and Cable
Specifications.”

10-Gigabit Ethernet Module Slots

The switch 10-Gigabit Ethernet module slots are used for uplink connection to other switches and
routers. The module slots operate in full-duplex mode and use the hot-swappable Cisco X2 transceiver
modules and the Cisco TwinGig Converter Module.

For the list of supported X2 transceiver modules, see the switch release notes on Cisco.com.

For more information about the 10-Gigabit Ethernet module slots, see the “Installing Devices in

10-Gigabit Ethernet Slots” section on page 2-12. For cable specifications, see Appendix B, “Connector
and Cable Specifications.”

Cisco TwinGig Converter Module

The Cisco TwinGig Converter Module, also known as the converter module, has two SFP module slots
that convert a 10-Gigabit slot into a dual SFP module interface to establish Gigabit uplinks to network
devices.

SFP Modules

Front Panel Description

For more information about the Cisco TwinGig Converter Module, see the “Installing X2 Transceiver

and Converter Modules” section on page 2-12. For cable specifications, see Appendix B, “Connector
and Cable Specifications.”

The Gigabit Ethernet SFP modules connect to other devices and provide uplink interfaces when inserted
in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45
connectors for copper connections. You can use any combination of these field-replaceable modules:

• 1000BASE-SX

• 1000BASE-T

The Catalyst 2350 switch supports the SFP module patch cable, a 0.5-meter, passive copper cable with
SFP module connectors at each end. The patch cable can connect two Catalyst 2350 switches in a
cascaded configuration.

For more information about SFP modules, see your SFP module documentation and the “Installing SFP

Modules” section on page 2-14. For cable specifications, see Appendix B, “Connector and Cable
Specifications.”

LEDs

You can use the switch LEDs to monitor switch activity and its performance. Figure 1-2 shows the switch
LEDs and the Mode button that you use to select one of the port modes.

Port LEDs and Modes

Each Ethernet port and 10-Gigabit Ethernet module slot has a port LED. These port LEDs, as a group or
individually, display information about the switch and about the individual ports. The port mode
determines the type of information displayed through the port LEDs.

Catalyst 2350 Switch Power-Supply Modules

The switches have one internal 265-W power-supply module (Tabl e 1-5). The 265-W AC-power-supply
module is an autoranging unit that supports input voltages between 100 and 240 VAC. The
DC-power-supply module has dual input feeds (A and B) and supports input voltages between 36 and 72
VDC.

The AC-power-supply module uses an 18-AWG power cord for connection to an AC power outlet. The
DC-power-supply module requires wiring to a DC-power source.

Management Ports

Rear Panel Description

You can connect the switch to a host such as a Windows workstation or a terminal server through the
10/100

Ethernet management port or the console port (shown in Figure 1-3). The 10/100 Ethernet
management port connection uses a standard RJ-45 crossover or straight-through cable. The console port
connection uses the supplied RJ-45-to-DB-9 female cable.

Safety Warnings

This section provides the basic installation caution and warning statements. Translations of the warning
statements appear in the Regulatory Compliance and Safety Information for the Catalyst
document that shipped with the switch and online at Cisco.com. Read this section before you start the
installation procedure.

Warning

To prevent the switch from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of 113•F (45•C). To prevent airflow restriction, allow at least
3 inches (7.6 cm) of clearance around the ventilation openings.

Warning

Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals.

Statement 43

Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury
