THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

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: The equipment described in this manual 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.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

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.

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Obtaining Additional Publications and Information

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

In addition to the interfaces listed in Tabl e 1-1, Cisco 2600 series routers include the following hardware features:

• Dynamic random-access memory (DRAM) for main memory and shared memory (Cisco 261x and

Cisco 262x routers)

• Synchronous dynamic random-access memory (SDRAM) for main memory and shared memory

(Cisco 26xxXM, Cisco 265x, and Cisco 2691 routers)

• Nonvolatile random-access memory (NVRAM) for storing configuration information

• Flash memory—Stores the operating system software image. In Cisco 2691 routers, flash memory

is a CompactFlash memory card. In all other Cisco 2600 series routers, flash memory is a single inline memory module (SIMM).

• EIA/TIA-232 (RJ-45) console port for local system access by using a console terminal

• EIA/TIA-232 (RJ-45) auxiliary port for remote system access or dial backup by using a modem

Figure 1-1 and Figure 1-2 show examples of Cisco 2600 series routers.

Interface Numbering

Each interface (port) on a Cisco 2610, Cisco 2620, and Cisco 2650 series router is identified by number as described in the following sections.

Interface Numbering

WAN and LAN Interface Numbering

Cisco 2600 series routers contain the following WAN and LAN interface types:

• Built-in LAN interfaces: Ethernet, FastEthernet, Token Ring

• Two or three slots in which you can install WAN interface cards (WICs)

• One slot in which you can install a network module

The numbering format is interface-type slot-number/Interface-number. Two examples are:

• Ethernet 0/0

• Serial 1/2

The slot number is 0 for all built-in interfaces and 0 for all WIC interfaces; the slot number is 1 for network module interfaces.

Interface (port) numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top.

Figure 1-11 shows a router of 1-RU height with:

• A WIC in each WIC slot (containing interface Serial 0/0 in physical slot W0, and interface Serial

0/1 in physical slot W1)

• A 4-serial-port network module in slot 1 (containing the following ports: Serial 1/0, Serial 1/1,

Serial 1/2, and Serial 1/3)

• First built-in Ethernet interface—Ethernet 0/0

• Second built-in Ethernet interface—Ethernet 0/1, or optionally in Cisco 2612 and Cisco 2613

routers only: Token Ring interface 0/0

Figure 1-12 shows a router of 2-RU height with:

• A 2-port T1 network module in slot 1 (containing the following ports: T1 1/0 and T1 1/1)

• Two built-in Ethernet 10/100 interfaces—Fast Ethernet 0/0 and Fast Ethernet 0/1

• A WIC in each WIC slot (containing interfaces Serial 0/0 and Serial 0/1 in physical slot W0,

interface Serial 0/2 in physical slot W1, and interface BRI 0/0 in physical slot W2)

–

If physical slot W0 is empty and physical slot W1 contains a 1-port serial WIC, the interface number in the WIC is numbered Serial 0/0.

–

If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1 is numbered Serial 0/2.

–

If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the interface in physical slot W1 is numbered BRI 0/0.

Note The slot number for all WIC interfaces is always 0. (The W0 and W1 slot designations are for

physical slot identification only.) Interfaces in the WICs are numbered from right to left, starting with 0/0 for each interface type, regardless of which physical slot the WICs are installed in.
