Chapter 6 Installing Power Supplies; Required Tools And Equipment - Cisco Nexus 7000 Hardware Installation And Reference Manual

Installing Power Supplies
This chapter describes how to install AC and DC power supplies in any Cisco Nexus 7000 Series chassis.
The AC power supplies convert the AC power from your facility to DC power for use in the chassis; the
DC power supplies take DC power from your facility for use in the chassis. In the same chassis, you can
install AC power supplies, DC power supplies, or a combination of AC and DC power supplies, but the
power supplies must be the right size for the power supply slots (you cannot mix the smaller power
supplies designed for the Cisco Nexus 7004 switch with the larger units designed for the Cisco Nexus
7009, 7010, and 7018 switches).
