ATTENTION: Do not force the module into the
backplane connector. If you cannot seat the module
with firm pressure, check the alignment and keying.
Forcing the module can damage the backplane
connector or the module.
5. Snap the chassis locking bar (or locking latch on earlier chassis)
over the top of the module to secure it. Make sure the locking
pins on the locking bar are fully engaged.
Note: The chassis locking bar will not close if all modules are not
properly seated.
