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. With over 70 modular
interface options, Cisco 3600 series routers provide solutions for data, voice, video, hybrid dial access,
Virtual Private Networks (VPNs), and multiprotocol data routing.

This chapter includes the following sections:

• Hardware Features, page 1-1

• Regulatory Compliance, page 1-15

Hardware Features

The Cisco 3600 series includes the Cisco 3620, Cisco 3640, Cisco 3631, and Cisco 3660 routers, which
have the following features:

• Two slots for Personal Computer Memory Card International Association (PCMCIA) cards

(Cisco 3620, Cisco 3640, and Cisco 3660 routers only)

• Flash memory capability

• Sockets for memory modules; either:

–

Four sockets for DRAM single in-line memory modules (SIMMs), user-configurable as shared
memory or main (processor) memory (Cisco 3620 and Cisco 3640 routers only)

–

Two sockets for SDRAM dual in-line memory modules (DIMMs), user-configurable as shared
memory or main (processor) memory (Cisco 3631 and Cisco 3660 routers only)

• High-speed console and auxiliary ports (up to 115.2 kbps)

• Hardware thermal alarm to warn of excessively high operating temperature

Note The Cisco 3660 router platform consists of two router models: Cisco 3661 and Cisco 3662. The

Cisco 3661 router with one Fast Ethernet interface (part number CISCO3661-xC) is shown in

Figure 1-5, and the Cisco 3662 router with two Fast Ethernet interfaces (part number CISCO3662-xC or

CISCO3662-xC-CO) is shown in Figure 1-6.

Figure 1-5 and Figure 1-6 show Cisco 3660 AC power supplies installed. The DC power supplies differ

in appearance but occupy the same bays in the router.

Note In this publication, references to Cisco 3660 routers include both Cisco 3661 and Cisco 3662 models.
