Chapter 3, “Installing and Removing AC- and
Alarm Input Port
The switch supports four alarm inputs. The alarm input is a dry-contact alarm port. Use the CLI to define
each alarm input to respond to a normally open or closed dry-contact closure and to define the alarm
severity as minor, major, or critical. When a condition triggers an alarm, the console displays an alarm
message, and the corresponding Alarm LED responds (see the
Cisco ME 3400E Ethernet Access Switch Hardware Installation Guide
1-4
“Alarm LEDs” section on page 1-11).
OL-16447-01
Chapter 1 Product Overview
Management Port
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. The 10/100 Ethernet management port connection
uses a standard RJ-45 crossover or straight-through Ethernet cable. The console port connection uses the
supplied RJ-45-to-DB-9 female cable.
The Ethernet management port operates in any combination of half duplex, full duplex, or 10 or
100 Mb/s, and its traffic is isolated from the other ports. See Tab le 1-7 for descriptions of the Ethernet
management port LEDs. See the “10/100 Ethernet Management Port” section on page B-3 for pinout
information.
For console port and adapter pinout information, see the “Console Port Adapter Pinouts” section on
page B-7.
10/100 Fast Ethernet Ports
You can set the 10/100 ports on the switch to operate in any combination of half duplex, full duplex, or
10 or 100 Mb/s. You can set the ports for speed and duplex autonegotiation. The default setting is
autonegotiate.
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
Front Panel
meters).
Dual-Purpose Ports
You can configure the dual-purpose ports on the switch as either 10/100/1000 ports or as SFP-module
ports. You can set the 10/100/1000 ports to autonegotiate. You can also configure them as fixed 10, 100,
or 1000 Mb/s (Gigabit) Ethernet ports.
By default, the switch dynamically selects the medium for each dual-purpose port (10/100/1000BASE-T
or SFP). When a link is achieved on one media type, the switch disables the other media type until the
active link goes down. If links are active on both media, the SFP-module port has priority, but you can
manually designate the port as an RJ-45 port or an SFP port by using the media-type interface
configuration command.
You can configure the speed and duplex settings consistent with the selected media type. For information
on configuring interfaces, see the switch software configuration guide.
SFP Modules
The switch Gigabit Ethernet SFP modules are used for connections to other devices. These transceiver
modules are field-replaceable, providing the uplink interfaces when inserted in an SFP-module slot. You
can use any combination of SFP modules. The SFP modules have LC connectors for fiber-optic
connections or RJ-45 connectors for copper connections.

For more information about SFP modules, see your SFP module documentation and the “Installing and
Removing SFP Modules” section on page 2-19. For cable specifications, see Appendix B, “SFP Module
Connectors.”
SFP Module Patch Cable
The switch supports the SFP-module patch cable, a 0.5-meter, copper, passive cable with SFP module
connectors at each end (see Figure 1-4). The patch cable connects two switches in a cascaded
configuration.

OL-16447-01
Chapter 1 Product Overview
See the “Inserting and Removing the SFP Module Patch Cable” section on page 2-21 for more
information about using the SFP module patch cable.
You can order the SFP module patch cable (part number CAB-SFP-50CM=).
UNIs, NNIs, and ENIs
The switch supports user-network interfaces (UNIs), network node interfaces (NNIs), and enhanced
network interfaces (ENIs). UNIs are typically connected to a host, such as customer premises equipment
(CPE) or a home access gateway. NNIs are typically connected to a router or to another switch. ENIs
have the same functionality as UNIs, but can be configured to support protocol control packets for
Cisco Discovery Protocol (CDP), Spanning-Tree Protocol (STP), Link Layer Discovery Protocol
(LLDP), EtherChannel Link Aggregation Control Protocol (LACP), or Port Aggregation Protocol
(PAgP). Every port is in an UNI, ENI, or NNI mode at any time, but not all ports have to all be set the
same.
By default, the dual-purpose ports on the Cisco ME 3400E-12CS-M and on the
Cisco ME 3400EG-2CS-A are configured as UNIs, and the SFP-only uplink ports are configured as
NNIs. You must specifically configure ports to be ENIs; no ports are ENIs by default. By default, the
10/100 ports on the Cisco ME 3400E-24TS-M are UNIs, and the dual-purpose ports are NNIs.
A port can be reconfigured from UNI to NNI or an ENI, and the reverse. When a port is reconfigured as
another interface type, it inherits all the characteristics of that interface type. For information on
configuring interfaces, see the switch software configuration guide.

Dual-Purpose Port LEDs
The dual-purpose port LEDs on the switch show the connection of either a copper-based connector or
an SFP module. See Figure 1-8. The ports can autonegotiate, or you can manually configure each
dual-purpose port as either an 10/100/1000 with copper connectors or as an SFP-module port, but not
both types at the same time.
Link fault. Error frames can affect connectivity, and errors such as excessive

Power Supply Features
The Cisco ME 3400E-24TS-M and Cisco ME 3400EG-12CS-M support two modular redundant power
supplies, either AC or DC. The switch requires a single power supply to operate. If a failure occurs with
a power supply, replace only that failed power supply to maintain redundancy.
See Chapter 3, “Installing and Removing AC- and DC-Power-Supply Modules,” for instructions on
installing the AC- and DC-power supplies. See Appendix A, “Technical Specifications,” for voltage and
other specifications.

Management Options
• Cisco IOS CLI
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 C, “Configuring the Switch with the
CLI-Based Setup Program.”
• CiscoView application
The CiscoView device-management application displays the switch image so that you can set
configuration parameters and 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.
• SNMP network management
You can manage switches from a SNMP-compatible management station that is running platforms
such as HP OpenView or SunNet Manager. The switch supports a comprehensive set of Management
Information Base (MIB) extensions and four Remote Monitoring (RMON) groups. See the switch
software configuration guide on Cisco.com and the documentation that came with your SNMP
application for more information.
