Expansion Cards for a W or U Model Chassis
The W or U model chassis accomodates expansion cards using riser cards. If your
motherboard supports a Supermicro universal I/O (UIO) card, the U model chassis
supports an additional three full-height expansion cards and three low prole expan-
sion cards. If the motherboard does not support a UIO, then the W model chassis
supports four full-height expansion cards and three low prole expansion cards.
Installing a UIO Card
1. Power down the system as described in Section 5-2 and remove the cover.
2. Release the clamp that secures all four full-height PCI shields (Figure 5-12).
Looking at the rear of the chassis, this clamp is in the right corner. Unscrew
the single screw that secures the clamp and rotate the clamp away from the
shields. Remove the blank PCI shield covering the expansion slot in the chas-
sis.
3. Place the UIO card horizontally in the rear left area of the chassis bottom and
insert it into the UIO slot in the motherboard, while aligning it with slot in the
rear of the chassis.
4. Secure the shield to the rear of the chassis with the lever.
