Connecting DC-Powered Switches to a Power Source

Some Summit switches come with installed power supplies that are designed to be connected to DC power. The instructions in this section provides additional details about connecting the following Summit switches:

You must adhere to specific safety requirements when you connect any of these Summit switches to a DC power source.



For centralized DC power connection, these products are intended to be installed in Restricted Access Locations – like dedicated equipment rooms and equipment closets – in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70.

An optional redundant power supply, the EPS-150DC, is available for use with the Summit DC-powered switches. When the EPS-150DC is used with a DC-powered Summit switch, the power supplies (internal and redundant) are fully fault tolerant and load-sharing. If one power supply fails, the other power supply will provide sufficient power to operate the switch. See EPS-150DC External Power Module (with EPS-T2) for further details.

Before you connect the switch to a power source, complete the physical installation of the switch as described in Installing Other Summit Switches in a Rack.
