The ARTM-HD installs into the rear of the ATCA enclosure, opposite an ATCA blade
server designed for compatibility with the AdvancedRTM specification. The
ARTM-HD connects to the blade server’s Zone 3 rear connectors through the
midplane. The ARTM-HD carries one serial port, one 10/100/1000 MBASE-T
management port (RJ-45), and two external SAS ports to its faceplate (
FIGURE 1-1 ).
FIGURE 1-2 shows the physical relationship between the blade server, ARTM-HD, and
the midplane in a typical ATCA system.
