Sun Server X2-8 Subassembly Module Overview

The subassembly module (SAM) resides inside the chassis and contains the midplane on the internal front-facing side of the SAM and the back side server components on the external rear-facing side of the SAM.

The SAM provides the interconnect between the AC power input lines and the power supply. It also provides the midplane interconnect between the back-end components (EMs, NEMs, and SP) and the front-side components (hard drives and CPU modules). Additionally, the SAM contains the cooling system for the CPU modules (CMODs). Cooling to the EMs, NEMs, and the SP module is provided by the power supply fans.

Note - The SAM is designated as a field-replaceable unit (FRU).

Four hot-pluggable fan modules (FMs) controlled by two fan module controller boards (FBs) provide chassis cooling capability for up to 800W per CMOD (front-to-back air flow).
Two hot-pluggable network express modules (NEMs) with four 10/100/1000Base-T Ethernet ports (per NEM), four 10 GigabitEthernet SFP+: SR, LR, LRM, Twin-ax (per NEM), and two (unsupported) 4x mini SAS connectors (6.0 Gb/s, 3.0 Gb/s, 1.5 Gb/s) (per NEM).
Eight hot-pluggable Constellation PCIe ExpressModules with 8x PCIe 5 GT/s or 2.5 GT/s.
A hot-pluggable SP module with two 10/100/1000Base-T chassis management ports, a serial console port (RJ-45), and a UCP (universal connector port) for a multiport cable that provides KVMS access.
AC power block. Four AC power connectors with latching mechanisms.
