Chassis Overview
The chassis consists of the front accessible components, internal components, and
components accessible from the back of the server:
Chassis Front Side Components
The following figure shows the front side components:
The front-side components include:
|

|
2
|
Four power supplies
|
|
3 and 4
|
Eight fan modules (FMs) in two fan frames
|
|
5
|
Two internal CMOD bays
|

Chassis Internal Components
The following figure shows the chassis internal components:
The chassis internal components include:
|
|
|
1
|
CPU module (CMOD) bays
|
CMOD bays can support either four or eight CMODs. Servicing
CMODs requires warm or cold service.
|
2
|
Midplane/busbar
|
The mid-plane assembly provides an interconnect between the
backside components and the front-side components. This
component requires cold service.
|
|
Chassis Backside Components
The following figure shows the chassis backside components:
The chassis backside components include:
|
|
|
1
|
System Module (SMOD)
|
The SMOD has internal components that can only be accessed by
removing it from the backside of the server.
|
2
|
Dual PCIe card carrier (DPCC) bay
|
The DPCC bay contains eight DPCCs and up to 16 PCIe cards.
|
3
|
