Cable Power Classes
Chassis and switches need to be able to dissipate the heat generated by high power I/O
cables and modules. The Mellanox IS5x00 series chassis are rated for cables up to class 2
as per the SFF committee classification (
SFF-8436.PDF
).

For a valid physical connection both ends of the cable must be connected to working
devices.
Take care to not impede the air flow through the ventilation holes next to the Infini-
Band ports. Use cable lengths which allow routing horizontally around to the side of
the chassis before bending upward or downward in the rack.
Do NOT mix replacement parts based on different generations of chip.
Do not install InfiniScale IV based replacement parts within a SwitchX® based chas-
sis and vice versa. All Replacement modules must be consistent with the Chassis fam-
ily and switch chip generation.
When hot-swapping any of the units, it is necessary to wait 1 minute after removing
the defective part before inserting the new part. This is necessary so that the manage-
ment module will start a new cycle checking through the leafs and spines for the FW
versions.
