Servicing System Module (Smod) Components; Remove The Smod - Oracle X5-8 Service Manual

DPCCs connect directly to connectors on the back of the CMODs, so DPCCs and CMODs have
a one-to-one relationship with one another. In a four CMOD-configured server, the first four
slots (right to left from the back of the server), are active. In an eight CMOD-configured server,
all eight slots are active.
DPCC Indicator Panel
Two indicator panels are located on the front of the DPCC. Both panels include an OK
indicator, a Service Action Required indicator, and two ATTN buttons. The buttons are used
to alert the OS to a request for DPCC/PCIe card removal and to request acknowledgement of a
DPCC installation. For a DPCC removal, the OS responds by lighting the indicators on the front
of the DPCC. For an installation, the OS lights the green OK indicators.
DPCC Population Rules
One populated DPCC with at least one PCIe card must be installed for each CMOD (four or
■
eight populated DPCCs).
All eight DPCCs must be installed in the system regardless of the system configuration and
■
whether the DPCC contains a PCIe card.
