Note Never leave a power supply slot empty. If you remo ve a po wer 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.
Fan Module
The Cisco Nexus 6004 switch has four fan modules. Although the switch can function when a fan stops
functioning within a fan module, if a whole fan module stops functioning, you must replace the fan
module. The Cisco Nexus 6004 switch supports the front to back airflow (N6K-C6004-F AN-F) and back
to front airflow (N6K-C6004-FAN-B).
Figure 1-6 shows a fan module.
Caution You must order all fan modules and power supplies in the same chassis so that they have the same
direction of airflow with coolant air entering the chassis from the cold aisle and exhausting to the hot
aisle.
