Chapter 1 Cisco uBR7200 Series Overview
Cisco uBR7200 Series Universal Broadband Router
Cisco uBR7246 Router
Note
This product is end of sale (EOS).
The Cisco uBR7246 router chassis has:
•
Four slots for cable interface cards
•
Two slots for port adapters (one slot for a dual-width port adapter)
•
One slot for an I/O controller
•
One slot for a network processing engine
A fully configured Cisco uBR7246 router can operate with only one installed power supply. A second
power supply may be installed in the chassis to provide load-sharing, redundant power, and
hot-swappable capabilities. In a chassis using two power supplies, if one power supply fails or is
removed, the other power supply immediately takes over the router’s power requirements and maintains
normal operation without interruption. See
Figure 1-1 on page 1-4
and
Figure 1-2 on page 1-5
.
Caution
If you are using two power supplies, ensure that each power supply is plugged into a separate branch
circuit.
Note
The Cisco uBR7246 router does not support a mix of AC-input and DC-input power supplies in the same
chassis. If an AC-input power supply is installed and you want to add a second, redundant power supply,
you must add another AC-input power supply. If you want a redundant DC-input power supply
configuration, you must remove any installed AC-input power supplies and replace them with two
DC-input power supplies.
A fully configured Cisco uBR7246 router, with two installed power supplies and all chassis slots filled,
weighs approximately 100 pounds (45.4 kg). For clearance requirements and rack-mount installation
considerations, refer to the
“Site Environment” section on page 2-6
