Cabling Guide Brackets Installation on Either Sides of the
Chassis (Line Boards Cables)
The 4700 cabling guide brackets are installed at the rear of the rack, in-line with the Line
Boards and are designed to accommodate adequate cable bend radius.
The cabling guide brackets are part of the basic chassis configuration.
Selecting the optimal InfiniBand cable length depends on the overall cluster configuration and
requires proper planning to produce orderly and maintainable cabling.
HyperScale cable guide requires an additional 1U of rack space, making the total height 20U
instead of 19U.
The 4700 space in the Rack should be free from obstructions such as power strips.
The rack mounted cabling guide bracket should be installed with its bend facing out, otherwise
it will prevent Line Boards from being inserted or removed.
It is recommended that the rack rails that overlap with the 19U of the 4700 chassis are free of
PDU and power inlets.
The 4700 cabling guide brackets are illustrated in the following section.
