The QSFP+ ports accept supported QSFP+ modules. The QSFP+ module provides
an MTP cable connector for connecting to external devices.
To install a QSFP+ module in a QSFP+ port on the switch, complete the following
steps.
Note: To avoid damage to the cable or the QSFP+ module, do not connect the cable
before the QSFP+ module is installed in the switch port.
The module has a mechanical guide key to prevent you from inserting the
module incorrectly.
Attention: To avoid damage to the fiber optic cables, follow these guidelines:
Do not route the cable along a folding cable‐management arm.

 When you attach the cable to a device on slide rails, leave enough slack in the
cable so that it does not bend to a radius of less than 38 mm (1.5 in.) when the
device is extended or become pinched when the device is retracted.
 Route the cable away from places where it can be snagged by other devices in
the rack.
 Do not overtighten the cable straps or bend the cables to a radius of less than 38
mm (1.5 in.).
 Do not put excess weight on the cable at the connection point. Make sure that the
cable is well supported.
