Question 1

What are Cisco ISR 4000 router modules and cards?

Accepted Answer

Cisco ISR 4000 router modules and cards are modular hardware components that extend the connectivity, security, and performance of the ISR 4000 series by adding interfaces (Ethernet, T1/E1, DSL, cellular), services (WAN optimization, security, voice) and advanced features.

Question 2

Which network interface modules are available for Cisco ISR 4000?

Accepted Answer

Cisco ISR 4000 supports Network Interface Modules (NIM) and Service Modules (SM-X), including Ethernet NIMs (1G, 10G), T1/E1 NIMs, DSL/Cable NIMs, LTE/4G modules, and integrated SM-X options for high-density Ethernet, WAN optimization and voice.

Question 3

How do I choose the right module for my Cisco ISR 4000 router?

Accepted Answer

Select modules based on required port types (Ethernet, T1/E1, cellular), bandwidth needs, form factor (NIM vs. SM-X), power/goals, and feature licenses. Review the data sheet for slot capacity, performance tiers, and IOS support.

Question 4

Are Cisco ISR 4000 modules hot-swappable?

Accepted Answer

Most Cisco ISR 4000 NIMs and SM-X modules support hot-swap when installed in routers with redundant power supplies and the correct IOS image. Always consult the hardware installation guide and pre-check compatibility.

Question 5

What maximum throughput do Cisco ISR 4000 modules support?

Accepted Answer

Throughput varies by module: e.g., SM-X-1GE ports support up to 1 Gbps each, LTE-A modules up to 150 Mbps, and SM-X-10GE up to 10 Gbps. Overall router performance is governed by the selected performance license tier.

Question 6

Can I mix different module types in the same Cisco ISR 4000 chassis?

Accepted Answer

Yes. You can install NIM, SM-X and integrated modules in the same ISR 4000 chassis within slot and power budget limits. Follow Cisco slot population and power-budget guidelines in the installation manual.

Question 7

How do I install a module in a Cisco ISR 4000 router?

Accepted Answer

1. Power off the router. 2. Remove the blank faceplate. 3. Slide the module into the slot until it locks. 4. Secure with screws. 5. Power on and verify installation with 'show platform' in the CLI.

Question 8

What power supplies are required for Cisco ISR 4000 modules?

Accepted Answer

Cisco ISR 4000 supports AC and DC power supplies with redundant options. Power-budget requirements vary by module; consult the hardware installation guide for the correct PSU model and wattage per module.

Question 9

Which SFP transceivers are compatible with Cisco ISR 4000 cards?

Accepted Answer

Compatible SFP/SFP+ optics include Cisco GLC series (GLC-SX-MMD, GLC-LH-SMD), 10G SFP+ (SFP-10G-SR, SR-LX), and DWDM modules. Verify optics support in the ISR 4000 software and hardware compatibility matrix.

Question 10

How do I upgrade firmware on Cisco ISR 4000 modules?

Accepted Answer

1. Copy the new IOS image to flash via TFTP/FTP. 2. Update the boot variable with 'boot system'. 3. Reload the router. 4. Confirm firmware version with 'show version'. For module-specific updates, follow Cisco TAC guidance.

Question 11

Do Cisco ISR 4000 routers support PoE modules?

Accepted Answer

Yes. ISR 4000 supports PoE via the SM-X-8-PoE module, delivering IEEE 802.3af/at power for IP phones, wireless access points and other PoE devices directly from the router.

Question 12

What WAN interface options are available for Cisco ISR 4000?

Accepted Answer

WAN options include T1/E1 NIMs, DSL/Cable NIMs, LTE/4G-A modules, Ethernet and fiber via SM-X or SFP, and optional voice/WAN optimization modules. Choose based on service provider and bandwidth requirements.

Question 13

How do I troubleshoot a faulty Cisco ISR 4000 module?

Accepted Answer

Check system logs with 'show log', verify module status via 'show platform', reseat the module, ensure IOS compatibility, inspect LEDs, and if unresolved, escalate to Cisco TAC with module serial details.

Question 14

Can I manage ISR 4000 modules with Cisco DNA Center?

Accepted Answer

Yes. Cisco DNA Center offers automated provisioning, inventory tracking, health monitoring, firmware management and analytics for all modules in the ISR 4000 series via its northbound APIs.

Question 15

What licensing is required for Cisco ISR 4000 interface modules?

Accepted Answer

Interface modules may require Performance, Security or Unified Communications licenses. Activate features through Smart Licensing. Refer to the feature-license matrix for each module in the Cisco product documentation.

Question 16

How do I verify module status on my Cisco ISR 4000 router?

Accepted Answer

Use CLI commands like 'show platform hardware slot status' or 'show inventory' to display module presence, part number, serial number and operational state on the ISR 4000.
