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.
To connect the fiber optic cable to the QSFP+ module, complete the following steps.
1. Remove the protective caps from the end of the fiber optic cable.
