A basic guide to riser card functionality and use for first time user new to bus extenders. |

extender and why would I need one? |

| Riser Card |
A riser card is a right angle expansion
card that is used to extend a slot for card in computer
to make room to plug it in. They are most commonly used
in low-profile, 1U and 2U rackmount chassis or embedded
systems. Riser cards cards plug into their respective
bus (they are available for PCI, PCI-X, AGP, AGP Pro,
PCI Express, ISA, or other busses) and rotate the peripheral
cards, that are plugged into the riser card, so that they
are parallel with the motherboard. Riser cards are available
in 1-slot passive risers all the way up to 3-slot passive
riser cards for 2U rackmounts.
For users that only have one PCI slot available on their
motherboard but require more, active riser cards are available
with PCI bridge chips on them to expand the PCI bus.

Right Angle Bus Extender |
Bus extenders are also riser cards however
they do not always rotate a card so it is parallel with
the motherboard. They are used like extension cords for
power outlets. They basically extend the bus to another
location so it is more convenient for the user.
Customers who have low profile applications such as
1U or 2U rackmount systems, embedded systems, or custom
projects where their peripheral cards plugged into the
onboard expansion slots are too tall for their application.
Or if that particular application requires them to relocate
their card to a different portion of their enclosure.
Riser cards and bus extenders can adapt your expansion
slots so that they work for you. |
