Fan exhaust for supervisor and I/O modules5Power supply units (up to 4)—these modules are
a combination of the following:
• 6 kW AC power supply (N7K-AC-6.0KW)
• 7.5 kW AC power supply
(N7K-AC-7.5KW-INT [international
plugs])(N7K-AC-7.5KW-US [US plugs])
• 6 kW DC power supply (N7K-DC-6.0KW)
• Blank filler plate (replaces missing power
supplies to maintain the designed airflow)

Figure 8: Standard Hardware Features on the Front and Sides of the Cisco Nexus 7018 Chassis, on page 16
and Figure 1-12 show the Cisco Nexus 7018 chassis as it appears when it is fully configured before including
cables for connections to the Internet and the console. The systems that are not fully configured with the
maximum number of supervisor modules, I/O modules, fabric modules, or power supplies have blank panels
installed in place of the missing components to maintain the designed airflow for system cooling.
Note
