The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If the equipment causes interference to radio or television reception, which can be
determined by turning the equipment off and on, users are encouraged to try to correct the interference by using one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Modifications to this product not authorized by Cisco could void the FCC approval and negate your authority to operate the product.

CHAPTER
1
Overview of Cisco 4000 Series ISRs
Cisco 4000 Series Integrated Services Routers (ISRs) are modular routers with LAN and WAN
connectivity. They support several interface modules, including Cisco Enhanced Service Modules
(SM-X) and Cisco Network Interface Modules (NIMs).
Cisco 4000 Series ISRs target these applications:
• Enterprise applications—Intended for mid-size aggregation and gateway router that is located in a
regional or large branch office:
–
WAN aggregation at Cisco Enterprise core
–
Internet gateway
–
Branch or regional office aggregation
–
Remote access aggregation
• Service provider applications—Intended for high-end Enterprise Branch environments:
–
High-end customer premises equipment (CPE) for business-quality Internet access
–
Service provider leased line aggregation
–
Provider edge (PE) and high-end customer edge (CE) for Layer 2 VPN or Layer 3 VPN services
–
Low-end Ethernet aggregation
Cisco 4000 Series ISRs are available in these models:
• Cisco 4461 ISR
• Cisco 4451-X ISR
• Cisco 4431 ISR
• Cisco 4351 ISR
• Cisco 4331 ISR
• Cisco 4321 ISR
• Cisco 4221 ISR
For more information on the features and specifications of Cisco 4000 Series Integrated Services Routers
(ISRs), refer to the Cisco 4000 Series Integrated Services Routers datasheet.
Note Sections in this documentation apply to all models of Cisco 4000 Series ISRs unless a reference to a
specific model is made explicitly.

1 SM-X slot 1 2 SM-X slot 2
3 SM-X slot 3
To remove an SM-X:
Step 1 Read the “Safety Warnings” section and disconnect the power supply before you replace any module.
Step 2 Access the SM-X slot. See Figure 1-3 for the various NIM and SM-X slot locations.
Step 3 Loosen the captive screws to open the slot cover.
Step 4 Pull the SM-X out of the connector on the motherboard. Keep the SM-X parallel with the motherboard
to prevent damage to the slot and standoff.
Note When you remove the SM-X slot 2, it removes the blank slot which is attached to the special divider.
See Figure 1-4.
Step 5 Place the SM-X in an anti-static bag to protect it from ESD damage.
Note For more details on installation of SM-Xs, NIMs, and Cisco E-Series Server Modules, see the hardware
installation guide for the particular module you have purchased.
