www.dell.com | support.dell.com The Power Connections on the Switch The S50V and S50N contain both AC and DC connections. An AC cable is supplied with the switch (see Supplying Power on page 27). You can connect one or both of the AC or DC inputs to power. If both connections are made and able to supply power, the switch will use them in load-sharing mode. The DC input to the switch uses industry-standard terminal leads on a terminal block. The S50V has four connections - ground (FG), -48 volt input, return (RTN), and Current Sharing, as shown in Figure 5-1: Figure 5-1. DC Terminals on the S50V The S50N has three DC connections - return (RTN), -48 volt input, field ground (FG) - from left to right. Figure 5-2. DC Terminals on the S50N The S50N-DC has two terminal blocks, each with the same three DC connections as the S50N. WARNING: A qualified electrician should make the DC connections. Installing the Backup DC Power Supply for the S50V The Redundant Power Supply Unit (PSU) for the S50V is a 470W AC/DC rectifier. It includes rackmounting hardware, an AC cable, and a cable to connect to the DC power leads on the S50V. The power supply is oversized to support the Power over Internet (PoE) feature, too large to install in the S50 External Power Shelf. Instead, to install the Redundant Power Supply in a rack, complete the steps below 30 | Installing Backup Power
