The Cisco SM-X-16G4M2X and SM-X-40G8M2X modules provide Small Form-Factor Pluggable (SFP) /Small Form-Factor Pluggable Plus (SFP+), 1 Gigabit, 2.5 mGiG, and 10G connectivity to the Cisco 4000 Series Integrated Services Routers (ISRs). They also, provide 10G-capable internal uplink to central forwarding data plane on modular ISR platforms.

The Cisco SM-X-16G4M2X and SM-X-40G8M2X service modules are capable of supporting standard Power over Ethernet (PoE), Power over Ethernet Plus (PoE+), Cisco Enhanced Power over Ethernet (EPoE), and Cisco Universal Power over Ethernet (UPoE) on all copper ports. A maximum of 60 watts of power for each copper port is supported by leveraging both signal and spare pairs.

This article describes how to install the SM-X-16G4M2X or the SM-X-40G8M2X module in the Cisco 4000 Series ISR. This installation includes the installation of Small-Form-Factor pluggable (SFP) modules. It also describes how to connect the service module in your network.

Limitations of Cisco SM-X-16G4M2X or SM-X-40G8M2X Service Modules

The limitations of the SM-X-16G4M2X and SM-X-40G8M2X service modules are:

  • Either the SM-X-16G4M2X or the SM-X-40G8M2X service module is supported within a single chassis.

  • Cisco NIM-ES2-4/NIM-ES2-8 and SM-X-16G4M2X cannot co-exist within a single chassis due to feature incompatibility. When you switch between legacy and next-generation switching modes, you need to reload the system.


    Note

    By default, the system boots up in legacy switching mode. In legacy switching mode, you can perform online insertion and removal of the previous generation NIM switching modules such as NIM-ES2-4/NIM-ES2-8. This does not introduce any behavior change in previous use cases.

  • After installing the service module, you must reload the system to enable and activate the new next-generation switching feature set.

Preparing for Installation

The following sections describe safety warnings, general maintenance guidelines, and safety recommendations that you must read before installing and using the service module:

DANGER

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. Statement 1044

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 not handled properly. Improper handling can result in complete or intermittent equipment failure. Always observe the following procedures to prevent electrostatic discharge damage (ESD) when installing, removing, or 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 a metal part of the router chassis.

General Maintenance Guidelines and Safety Recommendations for Cisco SM-X-16G4M2X Service Module

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 Service Module (SM). Connect the equipment end of the wrist strap to a metal part of the chassis.

  • Handle the SMs only by their edges. SMs 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 trip 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.

Installing SFP and SFP+ Modules

Before you begin

See the Cisco 4000 Series ISRs data sheet on Cisco.com for a list of supported SFP and SFP+ modules. Use only supported SFP/SFP+ modules on the router.


Warning
Class 1 laser product. Statement 1008

  • Do not remove the dust plugs from the SFP and SFP+ modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

  • Removing and installing an SFP and SFP+ module can shorten its useful life. Do not remove and insert any SFP/SFP+ module more often than is necessary.

  • To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.

  • When you insert several SFP and SFP+ modules in multiple ports, wait for 5 seconds between inserting each SFP/SFP+. This will prevent the ports from going into error disabled mode. Similarly, when you remove an SFP and SFP+ from a port, wait for 5 seconds before reinserting it.

Procedure

Step 1

Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Step 2

Find the send (TX) and receive (RX) markings that identify the top of the SFP/SFP+ module.

On some SFP/SFP+ modules, the send and receive (TX and RX) markings might be shown by arrows that show the direction of the connection.
Step 3

If the SFP/SFP+ module has a bale-clasp latch, move it to the open, unlocked position.

Step 4

Align the module in front of the slot opening, and push until you feel the connector snap into place.

Step 5

If the module has a bale-clasp latch, close it to lock the SFP/SFP+ module in place.

Step 6

Remove the SFP and SFP+ dust plugs and save.

Step 7

Connect the SFP and SFP+ cables.

LED Indicators

You can check the status of the SM-X-16G4M2X or SM-X-40G8M2X service module by referring to LED indicators. The following table summarizes the LED indicators that are located on the bezel of the service module.

I/O

Connecting to Cisco SM-X-16G4M2X or SM-X-40G8M2X Service Module

Before you can access the module, you must connect to the host router through the router console or through Telnet. After you are connected to the router, you must configure an IP address on the Gigabit Ethernet interface connected to your module. Open a session to your module using the hw-module session command in privileged EXEC mode on the router.

To establish a connection to the module, connect to the router console using Telnet or Secure Shell (SSH) and open a session to the switch using the hw-module session slot/subslot command in privileged EXEC mode on the router.

Use the following configuration examples to establish a connection:
Router# hw-module session slot/card
Router# hw-module session 0/1 endpoint 0
 
Establishing session connect to subslot 0/1

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

DANGER

To comply with the standard for electromagnetic compatibility and safety, connect the Cisco SM-X-16G4M2X or SM-X-40G8M2X 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.
