The minimum assembly bending radius (close to the connector) is 10x the cable’s outer diameter. The repeated bend (far from the connector) is also 10x the cable’s outer diameter. The single bend (far from the connector) is 5x the cable’s outer diameter.

**’Combined’ end is the ‘head’ where the cables join together, inserted into the switch. ‘Single’ end is the ‘tail’ which plugs into the HCA/NIC in a server.

L = Assembly Space. Minimum value depends on the backshell (connector housing) dimensions = the space for the cable assembly behind the rack door.

Handling Precautions and Electrostatic Discharge (ESD)

The cable is compatible with ESD levels in typical data center operating environments and certified in accordance with the standards listed in the Regulatory Compliance Section. The product is shipped with protective caps on its connectors to protect it until the time of installation. In normal handling and operation of high-speed cables and optical transceivers, ESD is of concern during insertion into the QSFP cage of the server/switch. Hence, standard ESD handling precautions must be observed. These include use of grounded wrist/shoe straps and ESD floor wherever a cable/transceiver is extracted/inserted. Electrostatic discharges to the exterior of the host equipment chassis after installation are subject to system level ESD requirements.

Cable Management Guidelines

It is important to follow the instructions and information detailed NVIDIA Cable Management Guidelines and FAQ Application Note to insure proper and optimal installation of this cable and avoid physical damage.
