- Frame-level hardware-based trunking (even distribution of frames across trunk links)

• A reduced-depth, rack-mount design using existing rail kits (fixed, mid-mount, or Telco rack

mount kits

• Extensive diagnostics and system-monitoring capabilities for enhanced high Reliability,

Availability, and Serviceability (RAS)

• Optimized airflow (a choice of front-to-back or back-to-front flow)

• A real-time clock (RTC) with battery

• SEEPROM for switch identification

• Voltage monitoring

• Fan monitoring

• Three temperature sensors

• I

C interface to monitor and control environmental aspects

NOTE

Port numbering for the Brocade VDX 6720 begins with 1, not 0.
