•A 240 VA protective shield on the I/O baseboard and the plastic dividers between PCI slots

The LED PC board contains both the green and amber LEDs, as well as the switch that controls the PCI slot power. These items will no longer reside on the I/O carrier baseboard. This LED board is mounted in the I/O tray directly above where the PCI cards were previously screwed into the tray ledge. The LEDs can be seen from both inside and outside of the chassis. Each switch hangs down off of the LED board so that it can be activated by the rocker mechanism as it is folded into the chassis. See Figure 3-9: Rocker Mechanism.

Figure 3-9: Rocker Mechanism

The rocker mechanism activates the slot power switch as it enters the I/O tray. The rocker can be released only from within the chassis. This is to prevent unintentional power down of PCI slots when the system is powered up and the chassis has not yet been pulled out of the rack. The rocker also acts as a retention mechanism for the PCI card. An additional retention mechanism at the back edge of the PCI card is currently being developed.

The opposite end of the PCI card is held in place by a plastic, snap-in, locking card guide. The guide, installed on the center support bracket, has a built in retention mechanism that secures the top-rear edge of the PCI card. (See Figure 3-10.)
