page 53.
Removal
Attention: Do not remove two power supplies at the same time if performing hot-plug
procedures. Power supplies are considered as hot-pluggable FRUs only if you remove
one power supply at a time. The power supplies can be removed from the front of the
I/O subsystem.
1. Disconnect the power cord from the power supply.
2. Unlatch the power supply handle and rotate the handle downward to unseat the
power supply.
Attention: Do not remove a power supply for more than four minutes. If you
cannot replace the power supply in less than four minutes, shut down the system
and then remove the power supply.
3. Pull the power supply straight out from the I/O subsystem.
Replacement
To replace the power supply, perform the steps in the removal procedure in reverse
order.
