Caution To maintain agency compliance requirements and meet EMI emissions standards in Cisco 7513, Cisco 7513-MX, and Cisco 7576 chassis with a single power supply, a power supply blank must remain in the power supply bay adjacent to the power supply. Do not remove this blank from the chassis unless you do so to install a redundant power supply.

Note To prevent system problems, do not mix AC-input and DC-input power supplies.

Warning High current levels on the power supply connections at the rear of the power supply bay are exposed with the power supply or blank removed. Do not insert anything conductive into the open power supply bay while power is ON.
