Product Overview

The Cisco ® SM-2GE-SFP-CU Service Module has 2 Small Form-Factor Pluggable (SFP) slots that can be plugged into Cisco Integrated Services Routers Generation 2 (ISR G2) Service Module slots to provide additional copper and optical Gigabit Ethernet ports
Figure 1 shows the Cisco SM-2GE-SFP-CU Service Module faceplate.

Figure 1. Cisco SM-2GE-SFP-CU Service Module


Cisco SM-2GE-SFP-CU Service Module is based on EHWIC-1GE-SFP-CU technology.
SFP & feature support is therefore identical to that of the EHWIC-1GE-SFP-CU module
More information on features and a list of supported SFPs is found in the EHWIC-1GE-SFP-CU Data sheet

Platform Support

The Cisco SM-2GE-SFP-CU Service Module increases the SFP port density in the Cisco 3900 and Cisco 3900E Integrated Services Routers.
The service module also carries the following:

• Support for a service module in any service module slot

• Support for 2 Ethernet high-speed SFP ports per service-module card

Table 1 lists the Cisco 3900 and 3900E Integrated Services Routers supported by the Cisco SM-2GE-SFP-CU Service Module and the Cisco IOS ® Software releases required to support the platforms.

Table 1. Cisco SM-2GE-SFP-CU on Cisco 3900 and 3900E Routers

Maximum number of SFP ports supported per chassis is 6 with any combination of EHWIC-1GE-SFP-CU and SM-2GE-SFP-CU modules

Note: The Cisco IOS Software releases provided are typically the minimum version required to support the platform, module, or feature in question. Use the Software Advisor (available to registered customers only) to choose the appropriate software for your Cisco product.


Service modules and network modules can be installed either before or after mounting the router.
Always make sure that the router is off when installing the Cisco SM-2GE-SFP-CU.
For important tips, safety warnings, and other information you need to know before and during installation of the Cisco SM-2GE-SFP-CU Service Module, refer to "Installing Cisco Network Modules and Service Modules in Cisco Access Routers" at:
Warning: To comply with the Telcordia GR-1089 Network Equipment Building Standards (NEBS) standard for electromagnetic compatibility and safety, connect the Gigabit Ethernet ports only to intrabuilding or unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The intrabuilding 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 intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.


This module is managed using existing Cisco IOS command-line interface (CLI) commands and external management tools such as Cisco Configuration Professional.
For configuration instructions, refer to the "Configuring Ethernet, Fast Ethernet, or Gigabit Ethernet Interfaces" chapter of "Configuring LAN Interfaces". The guidelines in this chapter apply to all Cisco modular access routers.
For more configuration instructions and other related documents, refer to the "Related Documents and Links" section on page 6 of that document.

Note: Use the show diag command to check the hardware information of the Cisco SM-2GE-SFP-CU module.

Port Numbering

For external interfaces, two-tuple numbering is followed. The interface is addressed as GigabitEthernet <slot/port>.
Use the show diag CLI command to display the hardware information of the Cisco SM-2GE-SFP-CU Service Module.

Note: On the Cisco 3900 Series routers, some slots are built into the chassis and some are external. Slots that are part of a network module have numbers that begin with "1". Refer to the "Slot, Port, and Interface Information" section of "Cisco 3900 Series and Cisco 2900 Series Hardware Installation Guide" for more information.


The Cisco SM-2GE-SFP-CU Service Module has an EN LED located on the right side of the module. This LED indicates that the module has passed its self-test and is available to the router.
Table 2 lists the EN LED colors and their meanings
