Powering up procedure

To power up a Myrinet system interconnect, plug the power cord into the standard

C14 power jack labeled 100–127/200–240 V-. The power cord is rated 10A for the

5U interconnect, and 15A for the 9U chassis. There is no power switch on the

enclosure, which prevents an accidental network shutdown.

Typical operating temperatures for the components of the switch are in the range

of 30–39 degrees Celsius (86–102 Fahrenheit). If you see temperatures in the range

of 50–55°C (122–131°F), the switch is too hot and shutdown may occur. Shutdown

occurs at 55°C (131°F) and operation resumes at 50°C (122°F).

The temperatures reported by the monitoring line card are not air temperatures,

but are the temperatures of the line card circuit boards on which the thermometer

chips are mounted. Hence, the temperatures reported are very close to the

temperatures of the components on the circuit boards. If the inlet air temperature

is 40°C (104°F), the monitoring line card circuit-board temperatures may be as

high as 50°C (122°F), even on the inlet side.
