2 Plug the power cords into the power cord receptacles on the rear of the expansion chassis.
3 Plug the other end of the power cords into the rack power source.
NOTE: Each expansion chassis takes approximately 3 minutes to power on (drives to spin up and/or
come online).
4 Turn on (1) the PSU0 power switch and then turn on the PSU1 power switch.
• Expansion chassis powers on within 3 minutes.
• While the expansion chassis power up, their LEDs blink. After the LEDs stop blinking—if no
LEDs on the front and back of the chassis are amber—the power-on sequence is complete, and
no faults have been detected.
• The Power on/Standby LED on the 5U Ops panel should be lit green when the chassis power is
activated.
• See 5U Chassis Ops Panel LEDs on page 128 for details pertaining to 5U84 Ops panel LEDs and
related fault conditions.
NOTE: Repeat these steps for any other expansion chassis within this configuration.
