4. If a card uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a
rubber safety cap. Arrange the disconnected cables in the cable management system, to prevent the
cables from developing stress points.
WARNING:
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to a transceiver emit laser light that can damage your eyes.
CAUTION:
are inserting or removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
CAUTION:
An arc smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
5. 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.
6. Simultaneously turn both the ejector handles counterclockwise to unseat the card.
7. Grasp the handles and slide the card straight out of the card cage halfway.
8. Place one hand around the front of the card and the other hand under it to support it. Slide the IOC
completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.
Do not look directly into a fiber-optic transceiver or into the ends
Do not leave a fiber-optic transceiver uncovered except when you
Avoid bending a fiber-optic cable beyond its minimum bend radius.
