Overview of Cisco 2600 Series Routers
Cisco 2600 series routers are modular access routers with LAN and WAN connections that can be
configured by means of interchangeable modules and WAN interface cards.
This guide discusses the router models listed in Table 1-1.
This chapter includes the following sections:
•Hardware Features, page 1-1
•Reading the Front-Panel LEDs, page 1-3
•Reading the Rear-Panel LEDs, page 1-5
•Interface Numbering, page 1-9
•System Specifications, page 1-11
•Regulatory Compliance, page 1-12
Hardware Features
Table 1-1 lists the router models described in this guide and summarizes the LAN interfaces supported
on each model. These router models are similar in functionality, but differ in the number of interfaces
that are supported as well as the system specifications. (See Table 1-6.)

Hardware Features
In addition to the interfaces listed in Table 1-1, Cisco 2600 series routers include the following hardware
features:
•Dynamic random-access memory (DRAM) for main memory and shared memory (Cisco 261xand
Cisco 262xrouters)
•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.
Note Cisco 2600 series routers are either single rack-unit (1RU) or two rack-unit (2RU) high.
Note The number and type of interfaces vary, depending on the specific router.

Reading the Front-Panel LEDs
The LEDs indicate the current operating condition of the router. By observing the LEDs, you can note
any fault condition that the router is encountering, and then contact your system administrator or
customer service, when necessary.
Figure 1-3 and Figure 1-4 show the locations of the LEDs on the front panel of Cisco 2600 series routers.
Table 1-3 and Table 1-3 describe these LEDs.

Interface Numbering
•For information on installing AIMs, refer to the following documents:
– AIM Installation Quick Start Guide: Cisco 2600, 3600, and 3700 Series
– Installing Advanced Integration Modules in Cisco 2600 Series, Cisco 3600 Series, and
Cisco 3700 Series Routers
•For information about installing DRAM, SDRAM, NVRAM, and flash memory SIMMs, refer to the
following hardware configuration note:
– Upgrading System Memory, Internal Flash Memory, and Root ROM in Cisco 2600 Series
Routers
•For information about installing CompactFlash memory cards, refer to the following hardware

Cards
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.
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

Interface Numbering
Figure 1-11 Interface Numbering in Chassis with 1-RU Height
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.
