FRU functional descriptions
K2 Summit system Field Replaceable Units (FRUs) are described in this section.
Front bezel assembly
The front bezel assembly includes the bezel, fans, and fan status board. The assembly has four fans
and provides cooling for the K2 Summit system chassis. Air intake is from the front of the K2
Summit system and outflow is through the rear. The assembly connects to the front interconnect
board and is secured to the chassis by two thumbscrews.
Disk modules
There are slots for disk modules in the K2 Summit system. The slots are located behind the front
bezel assembly in the front of the chassis. Each slot can contain one disk module, and each module
contains one hard drive. Depending on storage options, a K2 Summit system can be fully populated,
partially populated, or can contain no disk modules. Disk modules plug into the disk backplane
board.
Data is written or “striped” across the disks in a continuous fashion, which makes the disks a “stripe
group”. This stripe group appears as the V: drive to the Windows operating system.
