Dress the fiber-optic array cables so that they are not touching or blocking access to

Replace each T640-SIB with a SIB. Use the standard replacement procedure described

in the T640 Core Router Hardware Guide.
Do not bring any of the SIBs online.
NOTE: Ensure that the ejector handle tabs are properly mated inside their
corresponding chassis slots before you tighten the captive screws on the
ejector handles. You might have to close and open the handles a few times
before the tabs catch the slots.
