Figure 5-2: Ejecting a Switch Card

It is normal that the ejection is a little stiff while the line card’s front panel is

in contact with the front panel or bezels above and below. The bottom of each

front panel and the bottom of the top bezel have spring gasketing as an EMI

seal. Once the handles reach their outward extreme, the line card should slide

easily out of the card cage (Figure 5-3).

3.

The backplane power connector ( Figure 5-4) in the center of the line card

protrudes downward below other components on the bottom of the circuit

board. Before the card is completely free, lift the card slightly so that the

power connector will clear the top of the front panel or bezel below the line

card you are removing.

To insert a line card, reverse the previous steps. Be sure to start with the handles

in their out position, and guide the line card slowly and gently into the card guides.

The signal pins and ground blades on the high-density connectors on the line

card align themselves by means of alignment posts on the backplane. Conical

depressions on the line card connectors center themselves on the posts to align

the connectors with great precision. When you use the lever handles to complete

the insertion of the line card, you will hear the locks snap into place and see the

red tabs pop out.

When the connectors start to seat, you may see the Status LED momentarily

showing yellow before it becomes green. As the line card becomes fully inserted,

the Status LED should show green. The green Status LED indicates that the line

card has passed all of its self-tests and is operating.
