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.

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them,
and we strive to correct all vulnerabilities quickly. If you think that you might have identified a
vulnerability in a Cisco product, contact PSIRT:
• Emergencies — security-alert@cisco.com
An emergency is either a condition in which a system is under active attack or a condition for which
a severe and urgent security vulnerability should be reported. All other conditions are considered
nonemergencies.
• Nonemergencies— psirt@cisco.com
In an emergency, you can also reach PSIRT by telephone:
• 1 877 228-7302
• 1 408 525-6532
Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive
information that you send to Cisco. PSIRT can work from encrypted information that is compatible with
PGP versions 2.x through 8.x.
Preface
Never use a revoked or an expired encryption key. The correct public key to use in your correspondence

highlighted. Locate the serial number label on your product and record the information before placing a
service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3
and S4 service requests are those in which your network is minimally impaired or for which you require
product information.) After you describe your situation, the TAC Service Request Tool provides
recommended solutions. If your issue is not resolved using the recommended resources, your service
request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
Obtaining Technical Assistance
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone.
(S1 or S2 service requests are those in which your production network is down or severely degraded.)
Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business
operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
OL-7678-01
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.

Setting up the Switch
CHAPTER
1
Features
See the Cisco ME 3400 and Cisco ME 2400 Ethernet Access Switches Getting Started Guide that shipped
with the switch for instructions on how to initially configure your switch. The getting started guide also
covers switch management options, basic rack-mounting procedures, port and module connections,
power connection procedures, and troubleshooting help.
For instructions on setting up your switch using the command-line interface (CLI), see Appendix D,
“Configuring the Switch with the CLI-Based Setup Program.”
The Cisco ME switch can be deployed as a backbone switch, aggregating 10BASE-T and 100BASE-TX
Ethernet traffic from other network devices. The switch supports AC power and DC power. See the
switch software configuration guide for examples showing how you might deploy the switch in your
network. All Cisco ME switches have 24 10/100 ports and 2 small form-factor pluggable (SFP) ports.
• These are the switch models:
• Cisco ME-2400-24TS-AC
• Cisco ME-2400-24TS-DC
• The switch supports these SFP modules; also see the “SFP Modules” section on page 1-4.

10/100 Ports
OL-7678-01
You can set the 10/100 ports on the switch to operate in any combination of half duplex, full duplex,
10 Mbps, or 100 Mbps. You can set the ports for speed and duplex autonegotiation, in compliance with
IEEE 802.3ab. (The default setting is autonegotiate.)
Cisco ME 2400 Ethernet Access Switch Hardware Installation Guide
1-3
Front Panel Description
When set for autonegotiation, the port senses the speed and duplex settings of the attached device and
advertises its own capabilities. If the connected device also supports autonegotiation, the switch port
negotiates the best connection (the fastest line speed that both devices support and full-duplex
transmission if the attached device supports it) and configures itself accordingly. In all cases, the
attached device must be within 328 feet (100 meters).
UNIs and NNIs are supported on the Cisco ME switch. UNIs are typically connected to a host, such as
a PC or a Cisco IP Phone. By default, the 10/100 ports on the Cisco ME switch are configured as UNIs.
A port can be reconfigured from UNI to NNI and the reverse. When a port is reconfigured as another
interface type, it inherits all the characteristics of that interface type. All ports on the Cisco ME switch
are either UNI or NNI at any time.
For information on configuring interfaces, see the software configuration guide.
SFP Module Slots
The SFP module slots support the SFP modules that are supported on the Cisco ME switch. These are
listed in the “SFP Modules” section on page 1-4.
By default, the SFP module ports on the Cisco ME switch are configured as NNIs. A port can be
reconfigured from UNI to NNI and the reverse, but only four ports on the switch can be NNIs at the
same time.
Chapter 1 Product Overview
SFP Modules
For more information on configuring interfaces, see the software configuration guide.
The Cisco ME switch uses Gigabit Ethernet SFP modules to establish fiber-optic and 1000BASE-T
connections. These transceiver modules are field-replaceable, providing the uplink interfaces when
inserted in an SFP module slot. You can use the SFP modules for Gigabit uplink connections to other
switches. You use fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic SFP
module. You use Category 5 cable with RJ-45 connectors to connect to a copper SFP module.
The Cisco ME switch supports these Cisco SFP modules:
• 100BASE-BX
• 100BASE-FX
• 100BASE-LX
• 1000BASE-BX
• 1000BASE-LX/LH
• 1000BASE-SX
• 1000BASE-T
• 1000BASE-ZX
• CWDM
For more information about these SFP modules, see your SFP module documentation.

Management Options
Console Port
You can connect the switch to a PC by means of the console port and an RJ-45-to-DB-9 female cable.
If you want to connect the switch console port to a terminal, you need to provide an RJ-45-to-DB-25
female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from
Cisco. For console port and adapter pinout information, see the “Connector and Cable Specifications”
section on page B-1.
Management Options
These management options are available for the Cisco ME switch:
• Cisco IOS CLI
The switch CLI is based on Cisco IOS software and is enhanced to support desktop-switching
features. You can fully configure and monitor the switch from the CLI. You can access the CLI either
by connecting your management station directly to the switch console port or by using Telnet from
a remote management station. See the switch command reference on Cisco.com for more
information.
For setup instructions that use the CLI, go to Appendix D, “Configuring the Switch with the
CLI-Based Setup Program.”
• CiscoView application
The CiscoView device-management application displays the switch image that you can use to set
configuration parameters and to view switch 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.
