1 Hardware features By default, the BigIron RX Series switch polls the temperature sensor on each module every 60 seconds to get a temperature reading. Depending on the temperature readings for the modules, the system can do the following: • Leave the fan speed as is • Increase the fan speed • Decrease the fan speed • Shut down a module to prevent damage If the temperature of a module exceeds specified high temperature thresholds, the system generates a Syslog message and SNMP trap. The system can also shut the module down if the temperature exceeds the highest threshold. LEDs The BigIron RX-32 fan control modules include a bi-color LED, which indicates the status of the fans. Table 8 describes the LED. TABLE 8 LED Fan control module LED Position State Meaning Fan control module Rear of chassis Off LED Green Amber The fans are not receiving power.

Rack mount kit The BigIron RX Series switches are shipped equipped for mounting in a standard 19-inch (EIA310-D) rack as described: • The BigIron RX-4 and BigIron RX-8 are equipped with built-in mounting brackets and are shipped with mounting screws. • The BigIron RX-16 and BigIron RX-32 switches ship with two L-shaped mounting brackets and mounting screws. Alternatively, you can use a mid-mount kit (ordered separately) to center-mount the BigIron RX chassis using two L-shaped mounting brackets. The mid-mount kit comes with instructions for installing the mounting brackets and mounting the device in a rack. Contact Brocade for information about mid-mount kits. In a rack, you can install the following number of BigIron RX Series chassis depending on the model: • BigIron RX-32 - 1 BigIron RX-32 chassis 22 BigIron RX Installation Guide 53-1001811-01
