Removing and installing a power supply
Use this procedure to remove and install a power supply.
Attention: Depending on the blade configuration of the chassis and the number
of power supplies installed, the SAN768B-2 may be able to continue operating
during the replacement. See “Power specifications” on page 150 to determine your
power requirements. If insufficient power is present, the chassis will start powering
down blades until the power demand can be met.
