Expansion Cards and Expansion-Card Risers
The appliance supports up to four PCI Express (PCIe) expansion cards on two
expansion-card risers.
◆
Expansion-card riser 1 provides two PCIe x4-link Gen 2 expansion slots.
◆ Expansion-card riser 2 provides two PCIe x8-link Gen 2 expansion slots.
c
Expansion cards can only be plugged into the slots on the expansion-card risers.
Do not plug any expansion cards into the riser connectors on the system-board.
To identify expansion slots, see Expansion Cards and Expansion-Card Risers on
page 47.
Expansion Card Installation Guidelines
Observe the following notes and guidelines regarding the expansion-card slots:
◆ PCI Express Generation 2 and Generation 1 expansion cards are supported in
all slots.
◆
In slots 2, 3, and 4, expansion cards can have a maximum length of 24.13 cm
(9.5 in). Slot 1 supports a full-length (30.99-cm [12.2-in]) expansion card.
◆ The appliance supports three full-height expansion cards and one low-profile
expansion card (slot 2).
◆
Although slots 1 and 2 are physically PCIe x8 connectors, they function only as
PCIe x4-link slots.
◆ The expansion-card slots are not hot-swappable.
◆
Besides the integrated storage controller, the appliance supports a maximum of
two RAID controller expansion cards to manage external storage.
c
To ensure proper cooling no more than two of the four expansion cards can have a
power consumption of greater than 15W (up to 25W maximum each), not
including the integrated storage controller.
◆
Table 5 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.
