3 Open the 9U expansion module's access door and raise the guide pin by pulling it up and turning it
slightly as if it were a screw. Otherwise, the guide pin may scratch the front doors of the module on which
you are stacking it.
4 Lift the new 9U expansion module and, from the front of the library, place it in the desired location.
5 If there is already a module installed, secure the two modules together by tightening the two
thumbscrews at the base of the front of the module and the two thumbscrews located at the base of the
back of the module. Then lower the module's guide pin (located at the base of the front of the module)
by turning it and pushing it down.
6 Tighten all thumbscrews located at the base of the front and back of the modules.
7 Fasten the module to the rack with rack ears.
