Dell PowerConnect J-Series J-EX8216 Ethernet Switch Hardware Guide The fan trays continue to operate indefinitely and provide sufficient cooling even when a single fan fails provided the room temperature is within the operating range. You can check the status of fans and the chassis temperature from the Environment Status option in the Status menu on the LCD panel. See "LCD Panel in a J-EX8200 Switch" on page 19. You cannot replace a single fan. If one or more fans fail, you must replace the entire fan tray. WARNING: There is no fan guard on the fans. Be careful to keep your fingers clear of moving fan blades when you are removing the fan trays.

The Routing Engine (RE) modules, power supplies, fan trays, and line cards plug into the midplane from the front of the chassis. The Switch Fabric (SF) modules plug into the midplane from the rear of the chassis. The midplane contains an EEPROM that stores the serial number and revision level of the midplane. The midplane performs the following functions: • Power distribution-The midplane distributes power to all the switch components from the power supplies that plug into it. • Control-signal connectivity-The midplane transports the control signals exchanged by system components for monitoring, control, and management purposes. • Transfer of data between line cards and SF modules-The midplane provides connectivity for data traffic to and from the line cards and the SF modules. WARNING: High levels of electrical energy are distributed across the switch midplane. Do not touch the midplane connectors or any component connected to the midplane with any metallic object while you are servicing components installed in the switch.
