Chapter 3 High Availability and Redundant Operation
Power Supply Redundancy
Note AC power redundancy for the Cisco ASR 9010 Router, Cisco ASR 9922 Router, and Cisco ASR 9912
Router requires that power modules be installed in multiple power trays.
DC Power Redundancy
The DC power modules are a modular design allowing replacement without any outage. Each tray houses
up to three version 1 power modules or four version 2 power modules. Figure 3-7 shows the minimum
and maximum module configurations for the version 1 power modules. Figure 3-8 shows that version 2 is
similar, with a minimum of one module per tray.
The Cisco ASR 9000 Series Routers have two available DC power modules, a 2100 W module and a
1500 W module. Both types of power modules can be used in a single chassis. See Appendix A,
“Technical Specifications,” for power module specifications.
The slot location of a module in a tray is irrelevant as long as there are N+1 number of modules.
