Replacing or Installing Power Supplies
The Cisco Nexus 5500 Platform switches and the Cisco Nexus 5000 Platform switches support two
front-end AC or DC power supplies, but may be used with one power supply. The switches each require
one power supply, but you can include a second power supply for power redundancy. If you use only one
power supply, you must fill the second power supply slot with a blank module to maintain the designed
airflow.

The airflow direction must be the same for all power suply and fan modules in the chassis. You can order
all modules with front to back airflow but you can alternatively order back to front airflow for the Cisco
Nexus 5548UP switch modules. Back to front airflow modules have a black stripe.Make sure that all
modules have either a black strip for back to front or no stripe for front to back.
