Gaining Access to the Card Cage
Removing Rear Card Cage Slot Shields
The rear card cage is not protected by a cover plate. However, individual slots that are not
being used (no card installed) are protected by metal shields secured by two thumbscrews.
To remove a metal slot shield, loosen the two (2) thumbscrews (one at the top edge and one
at the bottom edge), and remove the shield from the card cage (see Figure 3-3).
Figure 3-3
Rear Card Cage Slot Shields
To install a slot shield, set the shield over the slot so that the screws are aligned with the
holes in the card cage frame. Tighten the two thumbscrews with a screwdriver so that they
are more than finger-tight. (The torque specification for the thumbscrews is 24-28
inch-lbs.)
Note that the left-most slot shield is a "transitional shield." This shield has a wide sidewall
for EMI emissions control. This transitional slot shield should always be located
immediately to the right of the right-most BC card.
If a slot shield does not fit easily into place when you are installing it,
NOTE
do not force it. Instead, lever the shield into place from the bottom, from
the top, or from the left side. Forcing the shield into place may damage
the EMI contacts on the right side of the shield.
