Cisco Systems Cisco 3600 Manual De Usuario

Cisco routers are normally shipped with network modules, WAN interface cards (WICs), voice interface 
cards (VICs), advanced integration modules (AIMs), and power supplies already installed. If you need 
to remove or install any of these items, refer to the applicable documents online.

If there are modules, interface cards, or power supplies to be removed or installed, Cisco suggests that 
you perform the installation or removal before you install the chassis. If a chassis cover needs to be 
removed, the chassis may have to be removed from the rack to permit cover removal.

The Cisco 3660 accommodates two AC or two DC hot-swappable power supplies (PS1 and PS2) in bays 
at the rear of the unit. Each unit provides up to 250 W of power, and a single installed power supply 
meets the router's requirements. The second installed power supply provides redundancy, load sharing, 
and increased system availability. It can be removed without affecting system operation.

If the required network modules, interface cards, and power supplies are already installed, proceed to 
the
