Power Supply
The Cisco Nexus 5596UP uses a front-end power supply. The chassis has slots for two power supplies.

power supply for power redundancy.
Table 1 -1 lists the power supplies that you can order with the Cisco Nexus 5500 Platform switches.
Note Front to Back (FAF) Airflow and DC Power Supply is now supported for the Cisco Nexus 5596T. For
