Expansion Cards and Expansion-Card Risers
Expansion Card Installation Guidelines
Your system supports up to six
Generation 2
PCIe expansion cards using
connectors on the system board and two expansion-card risers. To locate the
expansion-card connectors on the system board, see
Figure 6-1 and to locate
the
expansion-card connectors on the expansion-card risers, see
Figure 6-4 and
Figure 6-5.
The following are the slot configurations on the risers and the system board:
•Riser 1
– Slot 1: x8 link expansion slot (24.13 cm [9.5"] length)
– Slot 2: x4 link expansion slot (low-profile 24.13 cm [9.5"] maximum
length, with a standard height bracket)
• System Board
– Slot 3: x8 link expansion slot (
low-profile
24.13 cm [9.5"] length)
– Slot 4: x8 link expansion slot (
low-profile
24.13 cm [9.5"] length)
•Riser 2
– Slot 5: x8 link expansion slot (24.13 cm [9.5"] length)
– Slot 6: x8 link expansion slot (24.13 cm [9.5"] length)
NOTE: The length specified above is of the expansion cards.
NOTE: Ensure that both riser 1 and riser 2 are installed in the system before you
turn the system on.
CAUTION: To ensure proper cooling, only two out of the six expansion cards can
have a power consumption greater than 15 W (up to 25 W maximum), not including
the integrated storage controller.
Table 3-4 provides a guide for installing expansion cards to ensure proper
cooling and mechanical fit. The expansion cards with the highest priority
should be installed first using the slot priority indicated. All other expansion
cards should be installed in card priority and slot priority order.
