Power Supplies On both the S50N and S50V, either the AC or DC power supplies alone are sufficient to power the switch. When both AC and DC power supplies are connected, they act in roughly a 60%/40% load-sharing mode. WARNING: To prevent electrical shock, make sure the system is grounded properly. If you do not ground your equipment correctly, excessive emissions may result. Use a qualified electrician to ensure that the power cables meet your local electrical requirements. Fans Ventilation is side-to-side, with six fans on the left side of the switch as you face the PSU side. The fan speed increases when the temperature reaches 72 degrees C, and decreases to normal speed when the temperature falls to 57 degrees C. The switch never intentionally stops managing traffic. Status logging is identified by unit in the system log. Fan replacement in the field is not offered as an option.
