InfiniBand Cabling - QDR

Selecting proper InfiniBand cable lengths depends on the overall cluster configuration and
requires proper planning to produce orderly and maintainable cabling.
We recommend dressing the cables from each row of QSFP connectors into two groups
running them left and right, and fastening them down gently after connectivity was verified.
They will be routed down along the Rack side wall.
It is assumed here that the cable lengths and inter-rack cable routing have already been
determined.
The InfiniBand cables are connected to the 4036/2036 switch rear panel.

IMPORTANT: You can connect and disconnect cables while the 4036/2036 switch is
powered on.
