6. Lift the card into place and carefully align first the bottom, then the top of the card with the guides
inside the card cage.
7. Slide the card all the way into the card cage until you feel resistance.
8. For SCBs, observe these points regarding the ejector handles:
When removing or inserting an SCB, ensure that the SCBs or blank panels in adjacent slots are fully
inserted to avoid hitting them with the ejector handles. The ejector handles require that all adjacent
components be completely inserted so the ejector handles do not hit them, which could result in
damage.
The ejector handles have a center of rotation and need to be stored toward the center of the board.
Ensure the long ends of the ejectors located at both the top and the bottom of the board are vertical
and pressed as far as possible toward the center of the board. Once you have installed an SCB, place
the ejector handles in their proper position, vertically and toward the center of the board. To avoid
blocking the visibility of the LEDs,position the ejectors over the PARK icon.
To insert or remove the SCB card, slide the ejector across the SCB horizontally, rotate it, and slide it
again another quarter of a turn. Turn the ejector again and repeat as necessary. Use the indexing
feature to maximize leverage and to avoid hitting any adjacent components.
9. Grasp both ejector handles and rotate them simultaneously clockwise until the card is fully seated.
10. Insert the appropriate cable into the cable connector ports on each card. Secure each cable so that it
is not supporting its own weight. Place excess cable out of the way in a neatly coiled loop, using the
cable management system. Placing fasteners on a loop helps to maintain its shape.
CAUTION:
allow the fastened loops of a cable to dangle, which stresses the cable at the
fastening point.
CAUTION:
An arc smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
Do not let fiber-optic cables hang free from the connector. Do not
Avoid bending a fiber-optic cable beyond its minimum bend radius.
