Caution
Do not mix power supplies in Cisco 7200 VXR routers. In dual power supply configurations, both power supplies
must be of the same type (two AC-input power supplies or two DC-input power supplies).
Caution
To ensure adequate airflow across the router power supplies, a power supply or a power supply filler plate must be
installed in each power supply bay. Figure 18 shows a Cisco 7206VXR with an installed power supply filler plate.
Caution
The DC return connection to this system is to remain isolated from the system frame and chassis (DC-I).
