InfiniBand Cabling on Either Side of the Chassis (for Line Cables)

It is recommended to dress the cables connected to the InfiniBand connectors of each line
board into two groups, left and right, and fasten them down gently after connectivity has been
verified.
The cables from the same half of the line boards are bundled on the corresponding hangers and
will be routed down along the rack side wall.
Cables should be arranged so that each line board's cables do not interfere with the neighbor
line board insertion or removal.

To connect an InfiniBand cable to an sLB-4018 Line Board:
1. Route the cable to the nearest cabling guide bracket hanger position.
2. Position the InfiniBand cable connector with the pulling tab at top, and push the connector
in place.
3. Verify that the cable is inserted properly into the connector by gently tugging the cable;
verify that the Link State green-colored LED lights (and does not flash) indicating a good
physical connection.
4. Gently fasten in place with Velcro tie or tie wraps.

Avoid using tie wrap guns or similar tools; do not fasten the InfiniBand cable too tightly, as this
may cause irreversible damage to the cables. Tie wraps and zip ties can damage the cables.
Velcro tie is the recommended option.

Do not bend the InfiniBand cables too sharply. The recommended minimum bend radius is 4"
(10 cm).
