occurred.
v
QPI ports:
Insert either a QPI cable or a filler panel in each of these connectors.
Attention:

the high density interface. Dropping and incorrectly connecting the QPI cables
can damage the high density interface. Store the protective covers that come on
the end of the QPI cables for reuse when you perform maintenance on the
server or MAX5 or when you remove the cables for some reason.

v
DC power LED:
Each hot-swap power supply has a dc power LED and an ac
power LED. When the dc power LED is lit, it indicates that power supply is
supplying adequate dc power to the MAX5 expansion module. During normal
operation, both the ac and dc power LEDs are lit.
