1.4.1 Riser Mechanical
This is a PCI side view. The PCI connectors and the power connector are mounted on this
side. The ISA connectors mount to the reverse side. See Riser Details for details.

1.5 L2 Card
1.5.1 Motherboard L2 Card Connector for 5v Tolerant Systems
This is the footprint of the L2 tag/SRAM card connector (mounted on the motherboard). It
is suggested for installation on motherboards that can tolerate L2 cards having 5v outputs.
The reference design is supplied with this connector.
1.5.2 Outline Drawing of 5v Output L2 Card
This is an outline drawing of an L2 tag/SRAM card that has 5v outputs. This card will only
mount in the 5v tolerant motherboard connector. It will not mount in the 3.3v only
motherboard connector.
1.5.3 Motherboard L2 Card Connector for 3.3v Only Systems
This is the footprint of the L2 tag/SRAM card connector (mounted on the motherboard) It
is suggested for installation on motherboards that can not tolerate L2 cards that have 5v
outputs. The reference design does not use this connector.
1.5.4 Outline Drawing of 3.3v Output L2 Card
This is an outline drawing of an L2 tag/SRAM card that uses 3.3v outputs. This card can
mount in either motherboard connector.
