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.
