The equipment rack must begrounded to the same ground point used by the power service in your area. The ground path must bepermanent.Fans and AirflowVentilation is side-to-side, with six fans on the left side of the switch. For proper ventilation, position theswitch in an equipment rack (or cabinet) with a minimum of five inches (12.7 cm) of clearance around theside intake and exhaust vents. When two S-Series systems are installed side by side, position the twochassis at least 5 inches (12.7 cm) apart to permit proper airflow. The acceptable ambient temperatureranges are listed in Environmental Parameters on page 48.As listed in Table 2-2 on page 12 , the front panels of the S50N and S50V series have an Alarm statusLED, which is green when the switch is operating within required temperature parameters and allcomponents are operating normally, including fans. The LED is amber when the temperature orcomponents are outside expected parameters, red in a major alarm.The fan speed increases when the temperature reaches 72 degrees C, and decreases to normal speed whenthe temperature falls to 57 degrees C. The switch never intentionally stops managing traffic.SFTOS logs a temperature warning message when a temperature of 77 degrees C is reached, and logsanother message when the temperature returns to normal. The Command Line Interface (CLI) alsoreports an alarm.Use the show logging command to see the log messages. For details, see the System Logs chapters of theSFTOS Command Reference and SFTOS Configuration Guide.In a stack, each unit has its own temperature monitoring and control. Status logging is identified by unitin the system log.Fan replacement in the field is not offered as an option.PowerS50N-DCAs shown below, the right side of the S50N-DC contains two terminal blocks for two 150W DC powersupply inputs. The terminal blocks are labeled DC1 and DC2, which corresponds to the labels of thestatus LEDs on the front left of the switch. When both blocks are connected, they act in load-sharingmode with backup capability (one power supply can run the whole system).
