Chapter 1 Product Overview
Cisco 7600 Series Router Components
Note
The status LEDs and captive installation screws are in the same location on the 950 W AC- and DC-input
power supplies, in the 1900 W AC- and DC-input power supplies, and in the 2700 W AC- and DC- power
supplies.
The Cisco 7603-S router (
Figure 1-20
), Cisco 7603 router (
Figure 1-21
), and Cisco 7606 router
(
Figure 1-22
) power supplies have no external connectors but use a power entry module (PEM), located
on the front of the chassis, to connect the site power source to the power supply. For more information
on the PEM, see the
“PEM” section on page 1-32
.
The Cisco 7604 router, the Cisco 7606 router, and the Cisco 7606-S with the 2700 W AC power supply
(
Figure 1-25
) use an external power code directly connected to the AC power supply.
The Cisco 7604 router, the Cisco 7606 router, and the 7606-S router with the 2700 W DC input power
supply (
Figure 1-26
) uses an external terminal block on the back side of the chassis for input power
connection. The 7606-S router with the 4500 W DC input power supply (
Figure 1-27
) also uses an
external terminal block on the back side of the chassis for input power connection.
Both The AC-input and DC-input and DC-input power supplies support redundancy. When power is
removed from one supply, the redundant power feature causes the second supply to produce full power.
For power supply LED descriptions, see the
“Environmental Monitoring of the Power Supply” section
on page 1-32
. For complete power specifications, see
Appendix A, “Technical Specifications.”
