Note The ExpressCard strain-relief assembly cannot strain relieve cables when an
extended ExpressCard is installed. Also, the assembly may be unable to strain relieve
cables with very large or unusually shaped housings. However, when you cannot strain
relieve the ExpressCard cable, you still can secure the ExpressCard itself as shown in
Figure 1.
