Power Supplies
The Cisco Nexus 5548 switches uses a front-end power supply. The chassis has slots for two power
supplies. Two power supplies can be used for redundancy, but the Cisco Nexus 5548 switch is fully
functional with one power supply. See
Table 1-2
for the list of power supplies that you can order with
the Cisco Nexus 5548UP and 5548P switches. Note that the Cisco Nexus 5548P switch supports only
front-to-back (port-side exhaust) airflow and the Cisco Nexus 5548UP switch supports either
front-to-back (port-side exhaust) or back-to-front (port-side intake) airflows.
