To connect the VERSAstream™ VS-1022SX-SX SPAN Series aggregator/regenerator, refer to Figure 13 and follow these steps:

1.Two power supplies are provided. Use of the second power supply is strongly recommended to assure uninterrupted monitoring. Connect both power supply barrel connectors into the power 1 and 2 ports, respectively, of the VERSA- stream™. Plug the power supplies into the external power source, furthermore, connecting the second power supply to a different external power source circuit than the first power supply eliminates power as a single point of failure. The POWER 1 and 2 LEDs illuminate indicating power 1 and 2, respectively, are on. Either LED not illuminated indicates a defective power source and immediate replacement is required to insure redundant power integrity.
