Overview of Cisco 3600 Series Routers

Cisco 3600 series routers are modular access routers with LAN and WAN connections that can be configured by means of interchangeable modules and WAN interface cards. The modular design of the routers provides flexibility, allowing you to configure or reconfigure your router according to your needs.

This guide discusses the following router models:

• Cisco 3620 router (contains two slots)

• Cisco 3640 router (contains four slots)

• Cisco 3660 router (contains six slots)

This chapter includes the following sections:

• Hardware Features

• Network Modules and WAN Interface Cards

• Memory

• System Specifications

• Regulatory Compliance

Hardware Features

Figure 1-1 through Figure 1-3 show the front panels of the routers.

Figure 1-4 and Figure 1-5 show Cisco 3660 AC power supplies installed. The DC power supplies differ in appearance but occupy the same bays in the router.

Network Modules and WAN Interface Cards

In an effort to provide the latest information on network module and WAN (and voice) interface cards for Cisco 3600 series routers, this information is contained in separate publications that accompanied your router package.

• For information on network modules, see the publication Cisco Network Modules Hardware Installation Guide.

• For information on WAN interface cards, see the publication Cisco WAN Interface Cards Hardware Installation Guide.

• For software configuration information, see the publication Software Configuration Guide (for Cisco 3600 series and Cisco 2600 series routers).

These manuals are also on the Documentation CD-ROM that accompanied your router and on Cisco Connection Online (CCO). (See the "Cisco Connection Online" section, and the "Documentation CD ROM" section.)

Memory

Cisco 3600 series routers support the following types of memory:

• DRAM or SDRAM---Serves two functions: it stores the running configuration and routing tables and is used for packet buffering by the router's network interfaces. The Cisco IOS software executes from DRAM memory.

• Nonvolatile random-access memory (NVRAM)---Stores the system configuration file and the virtual configuration register. (For more information, see Appendix D, "Virtual Configuration Register.")

• Flash memory---Stores the operating system software image. You can also add Flash memory on PCMCIA cards.

• EPROM-based memory---Stores the ROM monitor, which allows you to boot an operating system software image from Flash memory or PCMCIA memory when Flash memory does not contain a valid boot image.

Table 1-1 through Table 1-3 list processor and memory specifications for the routers.

Regulatory Compliance

The following regulatory compliance information pertains to Cisco 3600 series routers.

FCC Part 68 Notice

The router complies with Part 68 of the FCC rules. On the bottom of the router is a label that contains, among other information, the FCC registration number. If requested, you must provide this information to the telephone company.

The router uses universal service order code (USOC) jacks as described in Table 1-7.

CS-03 Certification

The routers are CS-03 certified. Observe the following general information and safety precautions:

• The Industry Canada label identifies CS-03 certified equipment. This certification means that the equipment meets certain telecommunications network protection, operation, and safety requirements as described in the appropriate terminal equipment requirements document(s). The Department does not guarantee the equipment will operate to the user's satisfaction.

• Before installing the router, ensure that it is permissible to connect the router to the facilities of the local telecommunications company. The router must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

• Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

• Ensure that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

EMC Compliance

Cisco 3600 series routers comply with the following EMC standards:

• EN55022: 1994 Class B (including amendments 1 and 2)

• FCC 47CEF15 subpart B: 1997

• VCCI: V-3/97.04

• AS/NZS 3548: 1995

• BCIQ CNS 13438

EN55022/FCC Class B Compliance

The equipment described in this document generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco's installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
