QDR InfiniBand Switch Platform User Manual
PSUs. The connector side of the switch has the QSFP ports, system LEDs, and management con-
nection ports.
The switch platform contains auto-sensing 100 - 240 VAC connections for all possible PSUs.
The installer should use a rack capable of supporting the mechanical and environmental charac-
teristics of a fully populated platform.
The rack mounting holes conform to the EIA-310 standard for 19-inch racks. Take pre-
cautions to guarantee proper ventilation in order to maintain good airflow at ambient
temperature. Cable routing in particular should not impede the air exhaust from the
chassis.
3.6.2.1 Minimum and Maximum Rack Depth for this Switch
The short switch with the MIS000079 Rail kit can only go into a 19" rack whose vertical sup-
ports are between 380mm and 500mm apart.
To use the IS50XX in a rack deeper than 500mm, order the IS50XX with the stan-
dard depth, or order the MIS000083 rail kit. The both of these solutions will allow
you to install the switch in a 19" rack whose vertical supports are between 500mm
and 800mm apart.
The standard depth switch uses the MIS000085 rail kit for installation in a 19" rack whose verti-
cal supports are between 500mm and 800mm apart.
