Connecting the DC Wiring Harness to the DC Source Voltage

After the internal DC power supply is installed, it must be connected to a DC power source. A
three-wire, 6-foot long DC wiring harness is included with the Summit DC switch and internal DC
power supply. The DC wiring harness must be properly connected to the DC source voltage at your
facility by a qualified electrician before the connector on the wiring harness can be attached to the DC
power supply socket on the switch. Figure 66 shows the wiring harness and connector. For information
about the wire-to-pin connection, see Table 42 on page 202.
WARNING!
The Summit X450a-24tDC or Summit X450a-24xDC switch and rack must be connected to protective earth ground
before installing any switch components.
