Appendix F: Installing the SRX5400 Services Gateway Without a Mechanical Lift
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius. An arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
For SCB, observe these points regarding the ejector handles:
5.
When removing or inserting the SCB, ensure that the SCB 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 the 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.
Simultaneously turn both the ejector handles counterclockwise to unseat the card.
6.
Grasp the handles and slide the card straight out of the card cage halfway.
7.
Place one hand around the front of the card and the other hand under it to support it.
8.
Slide the card completely out of the chassis, and place it on the antistatic mat or in
the electrostatic bag.
CAUTION: The weight of the card is concentrated in the back end. Be
prepared to accept the full weight—up to 18.3 lb (8.3 kg)—as you slide the
card out of the chassis.
When the card is out of the chassis, do not hold it by the ejector handles,
bus bars, or edge connectors. They cannot support its weight.
Do not stack cards on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a flat,
stable surface.
