Replacing an AC Power Supply Unit During Operations
Step 5 Plug the other end of the power cable into the AC power source. The Input LEDs light up.
Step 6 Turn the Power switch from standby to on (from 0 to 1 as labelled on the power switch). The Output LED
lights up.
If one or more of these LEDs is red, turn the power switch to standby (0), check the AC power
connection, and then turn the power switch back on (1). The Input and Output LEDs for the connected
power supply units should be green.
For more information about the power supply unit LED states, see Appendix D, “Chassis and Module
LEDs.”
Removing an 6-kW or 7.5-kW AC Power Supply Unit During Operations
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing. Statement 1034
To replace an AC power supply unit while a Cisco Nexus 7000 Series switch is operating, follow these
steps:
Step 1 Make sure that the power supply units not being replaced have their power switches turned to ON.
Step 2 Turn the power switch on the power supply that you are removing to standby (STBY).
The Output LED turns off.
Step 3 Unplug the power cords from the AC power source. If the power supply unit has only one AC power
cable, unplug just that cable. Otherwise, unplug both AC power cables.
Step 4 Unscrew the four captive screws on the power supply unit so that they are no longer in contact with the
chassis.
Step 5 With one hand on the handle of the power supply unit, pull the unit part way out of the chassis.
Step 6 Place your other hand underneath the power supply unit to support its weight and then pull the unit fully
out of the chassis.
Step 7 Place the power supply unit on an antistatic mat or repack it in its original shipping materials. To repack
a 6-kW AC power supply unit, see Figure 10-1. To repack a 7.5 kW AC power supply unit, see
Figure 10-2.
