Remove a power supply
About this task
There are two power supplies. The power supplies are installed in the top and bottom nodes, and the top power supply is
installed upside-down. This procedure works for removing either power supply, however, the direction in which the retention bail
and release handle are pressed is reversed for the upside-down power supply.
NOTE: You do not need to power down the system to remove a power supply.
Steps
1. Rotate the power cable retention bail to the left (to the right for the upside-down power supply). Remove the power cable
from the power supply.
