Overview Of Cisco 2600 Series Routers
C H A P T E R1Overview of Cisco 2600 Series RoutersCisco 2600 series routers are modular access routers with LAN and WAN connections that can beconfigured 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 1-12Hardware FeaturesTable 1-1 lists the router models described in this guide and summarizes the LAN interfaces supportedon each model. These router models are similar in functionality, but differ in the number of interfacesthat are supported as well as the system specifications.

In Cisco 2691 routers, flash memoryis a CompactFlash memory card. In all other Cisco 2600 series routers, flash memory is a singleinline 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 modemFigure 1-1 and Figure 1-2 show examples of Cisco 2600 series routers.NoteCisco 2600 series routers are either single rack-unit (1RU) or two rack-unit (2RU) high.NoteThe number and type of interfaces vary, depending on the specific router.Figure 1-1Cisco 2600 Series Router Rear Panel—Example of 1RU RouterCisco 2650SERIAL 1Cisco 2650SERIAL 1CONNSERIAL 0SEE MANUAL BEFORE INSTALLATIONW1WICCONN 2A/SSERIAL 0CONNCONN100-240V– 1A50/60 Hz 47 WWIC2TSEE MANUAL BEFORE INSTALLATIONW010/100BASE-TEthernet 0/0(RJ-45)CONSOLEAUXConsoleport (RJ-45)Auxiliary port(RJ-45)31617LINK ETHERNET 0 ACTCisco 2600 Series Routers Hardware Installation Guide1-2OL-2171-06

Two examples are: Ethernet 0/0 Serial 1/2The slot number is 0 for all built-in interfaces and 0 for all WIC interfaces; the slot number is 1 fornetwork module interfaces.Interface (port) numbers begin at 0 for each interface type, and continue from right to left and (ifnecessary) 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 Serial0/1 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 2613routers only: Token Ring interface 0/0Cisco 2600 Series Routers Hardware Installation GuideOL-2171-061-9
