Hardware Features
Figure 1-4 Front Panel of the Cisco 3660 Router
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.
