What is a riser card?
An expansion card that is used to extend a slot for an I/O card in a
fully loaded computer to make room to plug it in. It may also refer
to a card that contains several slots used in low-profile,
space-saving enclosure. The I/O
cards are plugged into the riser card and reside parallel with the
motherboard.
Picture shown here identifies the PCI slots location on a 7-slots
standard ATX form factor board, from
left is PCI slot-1,
slot-2, slot-3, slot-4, slot-5, slot-6 and AGP slot-7 (Only PCI
slot-4, slot-5, slot-6 and AGP slot-7 on a micro ATX board).
The position of slot-6 lines up with the horizontal cutouts of the
rackmount chassis
The riser cards for 1U & 2U are not standard items. In general,
the slot that is next to the center mounting holes has to be PCI
slots, unless you choose the ones with ribbon cable. Usually 1U & 2U
come with a metal bar in the middle for securing the riser card. |
