Power supply and fans

The switch has a single power supply that converts 100–240 VAC to DC voltages for the various switch
circuits. Four internal fans provide cooling. The switch monitors internal air temperature, and therefore does
not monitor or report fan operational status. Air flow is front-to-back. To energize the switch, plug the
power cord into the switch AC receptacle (located on the back of the switch) and into a 100–240 VAC
power source.

Switch management

The switch supports the following management tools and protocols:
• QuickTools web
• Simple SAN Connection
• Command line
• Enterprise Fabric Management
• Simple Network Management
• Storage Management Initiative–Specification
• File transfer
