About the Cisco SM-X Layer 2/3 EtherSwitch Service Module

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,

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 right to left, 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:

Switch (config)# interface gi 0/3

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 and 10/100/1000 Ports

You can set the 10/100 ports on the Cisco SM-X Layer 2/3 ESM to operate in any combination of half duplex, full duplex, 10 Mbps, or 100 Mbps. You can set the 10/100/1000 ports to operate at 10 Mbps, 100 Mbps, or 1000 Mbps in full duplex. You can also set these 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).

Barring SM-X-ES3-24-P module ports, all 10/100 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.

 

Table 2 Port Speed and Duplex

Port Function
Explanation

Speed

The operating speed of the switch port. You can choose Auto (autonegotiation) if the connected device can negotiate the link speed with the switch port.

The default settings are:

  • Auto for the external 10/100-Mbps Fast Ethernet ports
  • Auto for the external Gigabit Ethernet RJ-45 (10/100/1000-Mbps) ports
  • 1000 Mbps for the SFP module ports

Duplex

The duplex mode of the switch port. Choose from one of the following:

  • Auto (autonegotiation) if the connected device can negotiate with the switch
  • Full (full duplex) if both devices can send data at the same time
  • Half (half duplex) if one or both devices cannot send data at the same time

The default settings are:

  • Auto for the external 10/100-Mbps Fast Ethernet ports
  • Auto for the external Gigabit Ethernet RJ-45 (10/100/1000-Mbps) ports
  • Full for the 1000-Mbps ports (SFP)

Note You cannot set the port to Half duplex if the port speed is set to Auto.

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:

  • GLC-LH-SM
  • GLC-S-MM
  • GLC-ZX-SM
  • GLC-BX-D
  • GLC-BX-U
  • GLC-T
  • GLC-GE-100FX

Note Only the 48-port Cisco SM-X Layer 2/3 ESMs support SFP.


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 Port LEDs on nonstacking Cisco SM-X Layer 2/3 ESMs only show link status.


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.

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 and Safety Recommendations for Cisco SM-X Layer 2/3 ESMs

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:

Installing or removing a router chassis

Working near power supplies

  • 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:

Use caution; do not become a victim yourself.

Turn off power to the room using the emergency power-off switch.

Determine the condition of the victim and send another person to get medical aid or call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

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.

Table 1-5 Maximum Power Dissipation and Consumption

Service Modules
Power Consumed and Dissipated
Power Passed Through

SM-X-ES3-16-P

40 W of 12 V power

480 W of -54 V

SM-X-ES3-24-P

47 W of 12 V power

720 W of -54 V

SM-X-ES3D-48-P

47W of 12 V power

1000 W of -54 V

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 Connecting a GE port to the network requires a Category 5 cable with RJ-45 male connectors, not provided with the switch module. Category 5 cables are widely available.



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.
