Install a Power Supply
This procedure describes how to install a power supply (PSU). When installing a PSU, ensure
that the pawl near the hinge of the latch engages the slot in the sidewall of the PSU bay. The
pawl supplies the necessary leverage to seat the PSU connector with the PSU backplane.
The correct power supply for the Sun Server X4-4 is the
A239C
model.
Caution -
System overheat and shut down. Installing the incorrect model of power supply can
cause the server to over heat. Install only the supported model.
