Remove the fiber-optic array cable connector from the fiber-optic array on the
5.
faceplate of theT640-SIB.
WARNING: Do not look directly into a connector at the end of a fiber-optic
adapter orfiber-optic array cable connector attached to an adapter. The
fiber optics emit laser light that can damage your eyes.
Install a dust cover on the cable connector you removed from the T640-SIB. Align
6.
the dust cover with the cable connector and carefully press them together until they
stop. The cover and the cable connector are keyed to ensure proper mating. Secure
the dust cover by tightening the thumbscrew and captive screw on the connector.
(Use the supplied small slotted screwdriver to tighten the captive screw.)
Move the fiber-optic array cables to the side of the T640-SIB so they do not interfere

9.
of the way out of the chassis.
Place one hand underneath the T640-SIB to support it and slide it completely out of
10.
the chassis. Place it on the antistatic mat.
CAUTION: Do not stack hardware components on one another after you
remove them. Place each component on an antistatic mat resting on a
stable, flat surface.
If you are not reinstalling a SIB into the emptied SIB slot within a short time, install a
11.
