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 System Power LED on the 2U Ops panel should be lit green when the chassis power is
activated.
• See 2U Chassis Ops Panel LEDs on page 118 for details pertaining to 2U Ops panel LEDs and
related fault conditions.
NOTE: Repeat these steps for any other expansion chassis within this configuration.
