Riser Boards The server board supports two riser boards, a 3.3-Volt riser board and a 5-Volt full-height riser board. The 3.3-Volt riser board is standard and the 5-Volt full-height riser board is optional. Features of the 5-Volt riser board include: • Support for three 33-MHz 5-Volt 64-bit PCI add-in cards • Provides 5-Volt to 3.3-Volt signal level translation • Support for a Zero Channel RAID (ZCR) card The 5-Volt riser board contains voltage level translation converting the 5-Volt PCI add-in card signals to conform to the server board, which has 3.3-Volt signaling levels. The board provides up to 25 Watts per slot. Figure 3-1 illustrates the 5-Volt riser board. Figure 3-1. 5-Volt Riser Board The 3.3-Volt riser card supports three 3.3-Volt 64-bit slots. The bus speed varies from 33 MHz to 133 MHz depending on the type of PCI adapters configured in the 3.3-Volt riser card. Figure 3-2 illustrates the 3.3-Volt riser board. Figure 3-2. 3.3-Volt Riser Board The 3.3-Volt riser board supports ZCR cards. To operate correctly, insert the ZCR card into the lower slot of the 3.3-Volt riser board, and then insert the 3.3-Volt riser board into the low-profile riser board slot on the server board. For the location of the low-profile riser board slot, see callout K on Figure 2-5. 30 Chapter 3

Riser Boards
The server board supports two riser boards, a 3.3-Volt riser board and a 5-Volt full-height riser board. The
3.3-Volt riser board is standard and the 5-Volt full-height riser board is optional. Features of the 5-Volt riser
board include:
•
Support for three 33-MHz 5-Volt 64-bit PCI add-in cards
•
Provides 5-Volt to 3.3-Volt signal level translation
•
Support for a Zero Channel RAID (ZCR) card
The 5-Volt riser board contains voltage level translation converting the 5-Volt PCI add-in card signals to
conform to the server board, which has 3.3-Volt signaling levels. The board provides up to 25 Watts per slot.
Figure 3-1 illustrates the 5-Volt riser board.
Figure 3-1.
5-Volt Riser Board
The 3.3-Volt riser card supports three 3.3-Volt 64-bit slots. The bus speed varies from 33 MHz to 133 MHz
depending on the type of PCI adapters configured in the 3.3-Volt riser card. Figure 3-2 illustrates the
3.3-Volt riser board.
Figure 3-2.
3.3-Volt Riser Board
The 3.3-Volt riser board supports ZCR cards. To operate correctly, insert the ZCR card into the lower slot of
the 3.3-Volt riser board, and then insert the 3.3-Volt riser board into the low-profile riser board slot on the
server board. For the location of the low-profile riser board slot, see callout K on Figure 2-5.
