Slot Bypass Board Manufacturers
Slot Bypass Card Description
Slot bypass boards are designed to act as a blank panel and extend all the way to the back plane to jumper backplane daisy chain signals. Some interface standards include signals that run from card slot-to-slot, daisy chained. The signals need either a card inserted in a slot or a jumper placed on the backplane to allow the signal(s) to pass to the next slot. Slot bypass boards jumper the signals eliminating the need for a circuit card or jumper on the backplane.
Slot bypass boards are also called air diverters because the blank metal plate that extends from the front of the chassis to the rear of the card cage blocks air from passing through that empty slot. Air diverters like Filler Panels are used in a chassis to cover an unused card slot, they are always blank and have no cut-outs. These panels may also be called an Air Dam.
A Slot By-Pass card stops air from moving out the front of the card cage [Filler Panel], and forces air toward cards on either side of the empty slot, cooling adjacent cards.
When metal Card Guides are used Slot By-Pass cards will also act as an EMI Shield between cards on either side of the slot. So a Slot By-pass card may provide EMI protection for the card cage by providing a blank panel and provide protection between adjacent cards.
