InfiniScale® IV 36-Port QSFP InfiniBand Switch User Manual
Note: Cables in the bottom row should be inserted up side down in relation to the how the cables are
inserted in the top row.
To remove, disengage the locks and slowly pull the connector away from the port receptacle. Both LED
indicators will turn off when the cable is unseated.
Care should be taken not to impede the air exhaust flow through the ventilation holes next to the InfiniBand
ports. Cable lengths should be used which allow for routing horizontally around to the side of the chassis
before bending upward or downward in the rack.
