This guide describes how to the install Cisco SM-X Layer 2/3 EtherSwitch Service Module (Cisco SM-X Layer 2/3 ESM) on the Cisco 2900 and Cisco 3900 Series Integrated Services Routers Generation 2 (ISR G2) and how to connect the ESMs to your network.
The Cisco SM-X Layer 2/3 EtherSwitch Service Modules 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.
Each router can support the maximum number of mixed service modules introduced in all releases. The service modules in Cisco IOS Release15.3(3)M and later releases 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
Cisco IOS Release15.3(3)M and later releases support the three above mentioned SKUs on Cisco ISR G2. These modules support 125 MHz, 2 Gb with ECC of system 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 any of the ISR-G2 router at the same time is dictated by the total service module slot present in the router. Table 1-1 lists the maximum number of service modules supported on each router.
For information about other features available in Cisco SM-X Layer 2/3 ESMs, see the Cisco SM-X Layer 2/3 EtherSwitch Service Module Configuration Guide.

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.
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.
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, 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 802.3at-compliant and noncompliant PoE devices such Cisco IP phones, Cisco access points, and some Cisco switches. Power over Ethernet, formerly referred to as inline power, is available in all network module form factors supported by Cisco routers.
Table 3 provides information on Cisco SM-X Layer 2/3 EtherSwitch Service Module port speed and duplex mode.
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.
All Cisco SM-X Layer 2/3 EtherSwitch Service Modules 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 4 lists the EN LED colors and their meanings.
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 5 explains how to interpret the port LED colors for link status on the Cisco SM-X Layer 2/3 EtherSwitch Service Modules.
- Safety Warnings
- Preventing Electrostatic Discharge Damage
- General Maintenance Guidelines and Safety Recommendations for Cisco SM-X Layer 2/3 ESMs
Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector or 2) while the housing is open, or both. Statement 1043
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026
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
Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Statement 1015
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection.
port #1~16 for SM-X-ES3-16-P, port #1~24 for SM-X-ES3-24-P, and port #1~ 48 for SM-X-ES3D-48-P Statement 1044
Electrostatic discharge (ESD) can damage equipment and electrical circuitry. Electrostatic discharge occurs when electronic printed circuit cards, such as those used in Cisco service module and network modules, are improperly handled and can result in complete or intermittent equipment failure. Always observe the following procedures to prevent ESD damage 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.
- 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.
- 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:
- Software Requirements for the Cisco SM-X Layer 2/3 ESM
- Removing the Cisco SM-X Layer 2/3 ESM from a Cisco ISR G2
- Installing the Cisco SM-X Layer 2/3 ESM in a Cisco ISR G2
- Verifying Cisco Cisco SM-X Layer 2/3 ESM Installation on a Cisco ISR G2
Caution 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 Cisco SM-X Layer 2/3 ESM. Connect the equipment end of the wrist strap to the metal part of the chassis.

Step 1 Read the “Safety Warnings” section before you perform any module replacement.
Step 3 Push the Cisco SM-X Layer 2/3 ESM into place until you feel the edge connector seat securely into the connector on the router backplane. The module faceplate should contact the chassis rear panel.
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.
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
Table 1-6 lists the maximum power dissipation and consumption for the use of the 12 V power on the Cisco SM-X Layer 2/3 ESM.
- 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 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.
A 10/100/1000 Gigabit Ethernet (GE) port or an SFP module 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.
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 intrabuilding cable must be shielded and the shield must be grounded at both ends.
