Q
What are Cisco Router ISR G2 SM ISM Modules?
A
Cisco Router ISR G2 SM ISM Modules are plug-in service modules (SM) and integrated service modules (ISM) designed to extend WAN, LAN, security, and voice functionality on Cisco 1900, 2900, and 3900 Series ISR Generation 2 platforms.
Q
Which SM ISM Modules are compatible with Cisco ISR G2 Routers?
A
Compatible modules include Cisco SM-ES2-2, SM-X-1GE-SFP, SM-4T, SM-X-8A/S, ISM-2FXS/2FXO, and ISM-2WIC-PWR for ISR 1900, 2900, and 3900 Series Generation 2 platforms.
Q
How do SM modules differ from ISM modules on ISR G2 Routers?
A
SM modules are hot-swappable WAN/LAN service modules that fit into dedicated SM slots; ISM modules integrate services like voice, PSTN, or PoE directly into the ISR G2 chassis expansion slot.
Q
How do I install an SM ISM Module in a Cisco ISR G2 Router?
A
Power off the router, remove the blank faceplate, slide the SM or ISM module into the designated slot until it clicks, secure it with the captive screw, then power on the router to auto-detect the new module.
Q
What performance benefits do SM ISM Modules provide on ISR G2?
A
SM ISM Modules deliver dedicated hardware acceleration for encryption, voice processing, and WAN optimization, enabling higher throughput, lower latency, and scalable services on ISR G2 platforms.
Q
Which interface types are supported by ISR G2 SM ISM Modules?
A
Supported interfaces include Gigabit Ethernet (copper and SFP), T1/E1/Serial, DSL, analog voice (FXO/FXS), GSM/3G/4G LTE, and PoE, depending on the selected SM or ISM model.
Q
How do I upgrade the firmware on ISR G2 SM ISM Modules?
A
Use Cisco IOS CLI or Cisco Configuration Professional to upload the latest SM/ISM firmware image to flash, then execute the 'service-module slot {slot} install' command to perform the upgrade.
Q
What are the power requirements for SM ISM Modules on ISR G2?
A
Power requirements vary by module: typical consumption ranges from 5W for pure data SMs up to 30W for voice or PoE ISMs. Refer to the Cisco datasheet for exact power draw per module.
Q
Can I hot-swap SM ISM Modules on a Cisco ISR G2 Router?
A
Yes, SM modules support hot-swap in ISR G2 Series; you can safely insert or remove most SMs without powering down the router. ISM modules generally require a reboot to fully initialize.
Q
How do SM ISM Modules enhance WAN connectivity on ISR G2 Routers?
A
SM ISM Modules add native WAN interfaces like T1/E1, xDSL, LTE, and SFP ports, enabling flexible, high-availability WAN links with hardware-accelerated QoS, encryption, and WAN optimization.
Q
Are Cisco ISR G2 SM ISM Modules covered by SMARTnet?
A
Yes, all Cisco ISR G2 SM and ISM Modules are eligible for Cisco SMARTnet® support contracts, which include 24/7 access to Cisco TAC, hardware replacement, and software updates.
Q
How do I troubleshoot common issues with SM ISM Modules on ISR G2?
A
Use 'show platform hardware service-module' and 'show platform hardware integrated-service-module' commands for status, verify IOS firmware compatibility, check power and cabling, and consult Cisco TAC logs.
Q
What is the maximum throughput achievable with SM ISM Modules on ISR G2?
A
Throughput depends on the ISR G2 model and services enabled. With Cisco Performance on Demand and hardware acceleration, ISR 3900 with SM/ISM can exceed 300 Mbps to 1 Gbps aggregate throughput.
Q
Do SM ISM Modules support advanced security features on ISR G2 Routers?
A
Yes, select SM and ISM models include hardware crypto engines for IPsec, DMVPN, SSL VPN, firewall, and Cisco Trust Anchor, ensuring line-rate encryption and advanced threat protection.
Q
What licensing is required for SM ISM Modules on Cisco ISR G2?
A
Most SM ISM Modules leverage the Universal IOS licensing model. You may need performance or feature licenses (e.g., Security or Unified Communications) to unlock full module capabilities.
Q
Where can I purchase genuine Cisco ISR G2 SM ISM Modules?
A
Authorized Cisco Partners, the Cisco online store, and certified resellers offer genuine ISR G2 SM ISM Modules with valid warranties, ensuring product authenticity and support eligibility.
Q
What warranty and lifecycle support exist for ISR G2 SM ISM Modules?
A
Cisco provides a limited lifetime warranty on SM ISM Modules for the life of the product. End-of-Sale and End-of-Life dates are published in Cisco’s product bulletin and lifecycle documentation.
