Switch, spine and monitoring line cards

The Myrinet system interconnect uses three types of cards. This chapter presents
the following information:
• A description of the switch card (Section 3.1).
• A description of the spine card (Section 3.2).
• A description of the monitoring line card (Section 3.3).

3.1 Switch card

The Myrinet system interconnect 8-port switch card (Figure 3-1) connects up to
eight nodes together. It has connectors to the backplane on the back side, and
connectors to external links on the front panel. It has a Status LED located on the
left front side of the card. This LED turns green after passing its self diagnostics.
If it fails, the LED turns yellow. These tests assess voltage levels, temperatures,
and internal status bits.
