Remove a DPCC
on the system module (SMOD). This internal slot is used for server HBA and provides SAS
connectivity to the server storage drives.
Dual PCIe Card Carriers (DPCCs)
The server contains eight hot-service PCIe Gen 3 DPCCs. Each DPCC has two low-profile
PCIe Gen 3 slots, an 8-lane slot and a 16-lane slot. Each DPCC can contain up to two PCIe
cards.
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 Fault-Service Required LED, 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.
For component serviceability, locations, and designations, see “Identifying
Components” on page 24 .
Remove a DPCC
This component is accessed directly from the back of the server. Dual PCIe Card Carriers
(DPCCs) can house two PCIe cards. You need to perform this procedure to replace or to remove
and install a PCIe card.
