Note Never leave a power supply slot empty. If you remove a power supply, replace it with another one. If you
do not have a replacement power supply, leave the non functioning one in place until you can replace it.
The Cisco Nexus 5548UP has front-to-back (port-side exhaust) or back-to-front (port-side intake)
airflow. The Cisco Nexus 5548P has front-to-back (port-side exhaust) airflow only. Figure 1-25 shows
the AC power supply, with two LEDs: one for power status and one for failure condition.

Caution The airflow direction should be the same for power supplies and fan modules.

The Cisco Nexus 5548 switches require two fan modules. Each fan module has four fans. If more than
one fan fails in one of these modules, you must replace the module. Figure 1-26 identifies the
