This section describes the Cisco SM-X Layer 2/3 ESM. It contains the following sections:
Cisco SM-X Layer 2/3 ESM Overview
The Cisco SM-X Layer 2/3 EtherSwitch Service Modules (ESMs) are switch modules to which you can connect Cisco IP phones, Cisco wireless access point workstations, and other network devices such as servers, routers, switches, and other network switch modules.
Cisco SM-X Layer 2/3 EtherSwitch Service Modules are supported on the Cisco 4451-X ISR.
Each router can support the maximum number of mixed service modules introduced in supported Cisco IOS XE releases. The service modules in Cisco IOS Release 15.3(3)M will have multiple SKUs with three different port densities:
- 16-port 10/100/1000 RJ45 L3 SKU
- 24-port 10/100/1000 RJ45 L3 SKU
- 48-port 10/100/1000 RJ45 plus 2 100/1000 SFP L3 SKU
These modules support 125 MHz, 2 Gb with error correcting code (ECC) of system double data rate (DDR2) running at 250 Mbps data rate and uses a 64 Mb Numonyx boot flash.
The maximum number of Cisco SM-X Layer 2/3 ESM units that can be present on the Cisco 4451-X ISR is dictated by the total service module slots present in the router. Table 1-1 lists the maximum number of service modules supported on the router,
For information about these and other features available in Cisco SM-X Layer 2/3 ESMs, see the Cisco SM-X Layer 2/3 EtherSwitch Service Module Configuration Guide at the following URL:

Cisco SM-X Layer 2/3 ESM Ports
The following sections describe the port numbering and port types on the service modules:
Port Numbering
The Ethernet ports are numbered left to right, top to bottom. The port numbering scheme to configure the ports on the Cisco SM-X Layer 2/3 ESM includes the port type (such as gi or gigabitethernet for Gigabit Ethernet), the module slot number (always 0), and the switch port number.
For example, to configure Gigabit Ethernet port 3 in slot 0, the interface configuration command would be:
Port Types
The following sections describe the port types on the service modules:
All Cisco SM-X Layer 2/3 ESMs, use RJ-45 connectors to provide Gigabit Ethernet (GE) connections.
Note
Cisco SM-X Layer 2/3 EtherSwitch Service Modules do not have a physical console interface, but they are accessible for software configuration and other operational procedures through console sessions between the Cisco SM-X Layer 2/3 ESM and the host router.
10/100/1000 RJ45 Ports
You can set the 10/100/1000 RJ45 ports for speed and duplex autonegotiation in compliance with IEEE 802.3ab. (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 Cisco SM-X Layer 2/3 ESM port negotiates the best connection (that is, 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 100 meters (328 feet).
All 10/100/1000 RJ45 ports on the Cisco SM-X Layer 2/3 ESM can provide power to IEEE 802.3af-compliant and non-compliant PoE devices. Power over Ethernet (PoE) devices are Cisco IP phones, Cisco access points, and some Cisco switches. PoE, formerly referred to as inline power, is available in all service module form factors supported by Cisco modular access routers.
Table 2 provides information on Cisco SM-X Layer 2/3 ESM port speed and duplex mode.
SFP Modules
The Cisco SM-X Layer 2/3 ESM supports Gigabit Ethernet SFP modules for fiber-optic connections. These laser optical transceiver modules are field-replaceable, and you can insert them into an SFP module slot. You can use fiber-optic cables with local connectors (LC) to connect to an SFP module. You can use the SFP modules for gigabit uplink connections to other devices.
The SFP modules support 850- to 1550-nm nominal wavelengths.
You can install the following SFP module types in the Cisco SM-X Layer 2/3 ESMs with SFP module slots:
Note
Cisco SM-X Layer 2/3 ESM LEDs
Cisco SM-X Layer 2/3 ESM LEDs provide green, amber, and off states for system and port status. The following sections describe LEDs on the service modules:
Note
EN LED
All Cisco SM-X Layer 2/3 ESMs have an enable (EN) LED. This LED indicates that the module has passed its self-test and is available to the router. (See Figure 4.) Table 3 lists the EN LED colors and their meanings.
Port LEDs
Each port has a port LED. These port LEDs, as a group or individually, display information about the module and about the individual ports. Table 4 explains how to interpret the port LED colors for link status on the Cisco SM-X Layer 2/3 ESMs.

Preventing Electrostatic Discharge Damage
Electrostatic discharge can damage equipment and electrical circuitry. Electrostatic discharge occurs when electronic printed circuit cards, such as those used in Cisco service modules are improperly handled and can result in complete or intermittent equipment failure. Always observe the following procedures to prevent electrostatic discharge damage (ESD) when installing, removing, and replacing any electronic printed circuit cards:
- Make sure that the router chassis is electrically connected to earth ground.
- Wear an ESD-preventive wrist strap, and make sure that it makes good contact with your skin.
- Connect the wrist strap clip to an unpainted portion of the chassis frame to channel unwanted ESD voltages to ground.
- The wrist strap and clip must be used correctly to ensure proper ESD protection. Periodically confirm that the resistance value of the ESD-preventive wrist strap is between 1 and 10 megohms (Mohm).
- If no wrist strap is available, ground yourself by touching the metal part of the router chassis.
General Maintenance Guidelines
- Keep the router chassis area clear and dust-free during and after installation.
- If you remove the chassis cover for any reason, store it in a safe place.
- Do not perform any action that creates a hazard to people or makes equipment unsafe.
- Keep walk areas clear to prevent falls or damage to equipment.
- Follow installation and maintenance procedures as documented by Cisco Systems, Inc.
- Always wear an electrostatic discharge (ESD)-preventive wrist strap and ensure that it makes good contact with your skin when you remove or install an EtherSwitch Service Module (ESM). Connect the equipment end of the wrist strap to the metal part of the chassis.
- Handle the ESMs by the edges only. ESMs are ESD-sensitive components and can be damaged by mishandling.
Safety Recommendations
To prevent hazardous conditions, follow these safety recommendations while working with this equipment:
- Keep tools away from walk areas where you or others could fall over them.
- Do not wear loose clothing around the router. Fasten your tie or scarf and roll up your sleeves to prevent clothing from being caught in the chassis.
- Wear safety glasses when working under any conditions that might be hazardous to your eyes.
- Locate the emergency power-off switch in the room before you start working. If an electrical accident occurs, shut the power off.
- Before working on the router, turn off the power and unplug the power cord.
- Disconnect all power sources before doing the following:
–
- Do not work alone if potentially hazardous conditions exist.
- Always check that power is disconnected from a circuit.
- Remove possible hazards from your work area, such as damp floors, ungrounded power extension cables, or missing safety grounds.
- If an electrical accident occurs, proceed as follows:

Power Specifications for the Cisco SM-X Layer 2/3 ESMs
The Cisco SM-X Layer 2/3 ESMs supports inline power on IP phones with –48 V power. This allows IP phones to be plugged into a standard RJ-45 jack and be powered from the switch rather than from an AC wall outlet.
The Cisco SM-X Layer 2/3 ESM distributes the –48 V power to each of the Ethernet ports that are configured for PoE. Each port can be independently configured for PoE.
The following limitations and specifications apply to the 12 V and -48 V power supplied to the ESM:
Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. Statement 1072
ESM 12-Volt Power Requirements
Table 1-5 lists the maximum power dissipation and consumption for the use of the 12 V power on the Cisco SM-X Layer 2/3 ESM.
PoE 48-Volt Power Restrictions
The following are the Power over Ethernet (PoE) 48 V power restrictions:
- Some platforms may limit –48 V power to a lower level than the maximum.
- The service module connector supports the 802.3at isolation requirements for the PoE/PoE+.
- The –48V power can dip to a low of approximately 46.2 V for a short duration when the system power supply fails and the RPS supply takes over.
- The Single Wide design can draw a maximum of 750 W on a supported platform.
- The Double Wide design can draw a maximum of 1000 W on a supported platform.
- The software must manage per-port current for each switch SKU without exceeding the total available PoE power.
Connecting to the Cisco SM-X Layer 2/3 ESM Ports
Both FE and GE ports are used to connect PCs or workstations to the network.
A 10/100/1000 Gigabit Ethernet (GE) port can be used as an uplink port to connect to another router or a server, or the GE port can trunk to another Cisco SM-X Layer 2/3 ESM or switch located in the same chassis or in a separate installation.
Note
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the Cisco SM-X Layer 2/3 ESM only to intra-building or unexposed wiring or cable. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. The intra-building cable must be shielded and the shield must be grounded at both ends.
