Chapter 1 Product Overview
Cisco 7600 Series Router Components
Note For the Cisco 7606 router, you can mix one 2700 W AC-input (PWR-2700-AC) load-sharing power
supply with one 2700 W DC input (PWR-2700-DC) load-sharing power supply.
• Cisco 7604 router and Cisco 7606-S router—Ability to house two fully redundant, AC-input or
DC-input, load-sharing power supplies
Note For the Cisco 7604 router and Cisco 7606-S router, you can mix one AC-input load-sharing
power supply with one DC-input load-sharing power supply.
• Cisco 7609 router, Cisco 7609-S, and Cisco 7613 router—Ability to house two fully redundant,
AC-input or DC-input, load-sharing power supplies
Note For the Cisco 7609 router, Cisco 7613 router, and Cisco 7609-S router, you can mix one
AC-input load-sharing power supply with one DC-input load-sharing power supply.
Note In certain configurations using modules with high power dissipation, the power supplies are
not fully redundant. See the
“WarningThis unit is intended for installation in restricted
access areas. A restricted access area can be accessed only through the use of a special tool,
lock and key, or other means of security.” section on page 2-2 to calculate your power
requirements.
• Cisco 7603 router, Cisco 7603-S router, Cisco 7604, Cisco 7606 router, Cisco 7606-S router, and
Cisco 7613 router—A hot-swappable fan assembly containing multiple fans
• Cisco 7609 route and Cisco 7609-S—Redundant hot-swappable fan assemblies containing multiple
fans
• Redundant backplane-mounted clock module
Component Hot Swapping
You can hot swap all modules (including the supervisor engine if you have a redundant supervisor
engine) and fans. You can add, replace, or remove modules without interrupting the system power or
causing other software or interfaces to shut down.
Note Although the FlexWAN module supports hot swapping, individual port adapters do not. To replace port
adapters, you must first remove the FlexWAN module from the chassis and then install or replace port
adapters as required.
