Attention: To avoid damage to the fiber optic cables, follow these guidelines:
v
Do not route the cable along a folding cable-management arm.
v 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.
v
Route the cable away from places where it can be snagged by other devices in
the rack.
v
Do not overtighten the cable straps or bend the cables to a radius of less than 38
mm (1.5 in.).
v Do not put excess weight on the cable at the connection point. Make sure that
the cable is well supported.
