Installing Power Supply Units

This chapter describes how to install AC and DC power supply units in any Cisco Nexus 7000 Series
chassis. The AC power supply units convert the AC power from your facility to DC power for use in the
chassis; the DC power supply units take DC power from your facility for use in the chassis. In the same
chassis, you can install AC power supply units, DC power supply units, or a combination of AC and DC
power supply units. If there are open power supply bays, you must fill them with blanks to maintain the
designed airflow.

Installing Power Supply Units
You can install up to two power supply units in the Cisco Nexus 7009 chassis, up to three power supply

chassis. In each type of chassis, you must fill each power supply bay with one of the following to
maintain the designed airflow for the chassis:

For the Cisco Nexus 7009 switch, the chassis ships with its power supply units already installed. For the
Note
Cisco Nexus 7010 and 7018 switches, the power supply units ship with the chassis but are boxed
separately, so you must install them using the instructions provided in this chapter.
When you install AC and DC power supply units in a Cisco Nexus 7000 Series chassis, you mount them
in the same way, but you ground them differently. For an AC power supply unit, you automatically
ground it when you connect it to the AC power source. For a DC power supply unit, you must connect
the power supply unit to the earth ground before you connect it to the DC power source.
