Chapter 1 Product Overview Power Connectors Caution You must connect the Catalyst 2924M XL DC switch only to a DC-input power source that has an input supply voltage from -36 to -72 VDC. If the supply voltage is not in this range, the switch might not operate properly or might be damaged.
Chapter 1 Product Overview Power Connectors RPS Connector on the Catalyst 2912 LRE and 2924 LRE XL Switches The RPS is a 300W redundant power system that can support six external network devices and provides power to one failed device at a time. It automatically senses when the power supply of a connected device fails and provides the necessary power to the failed device to prevent loss of network traffic.
