Installing System Components 119
• Three full-height, half-length PCIe x4 (slots 1, 4, and 5)
To identify expansion slots, see Figure 6-1.
Expansion Card Installation Guidelines
Observe the following notes and guidelines regarding the expansion-card
slots:
• The expansion-card slots are not hot-swappable.
• PCI Express Generation 2 and Generation 1 expansion cards are supported
in all slots.
• Although slots 1, 4, and 5 are physically PCIe x8 connectors, they function
only as PCIe x4 link slots.
• Slots 2 and 3 support full-length expansion cards; slots 1, 4, and 5 support
half-length expansion cards.
• The system supports up to two SAS or PERC expansion cards (in addition
to the integrated storage controller) to manage internal tape drives or
external storage.
CAUTION: To ensure proper cooling, no more than two of the five expansion
cards can have a power consumption of greater than 15 W (up to 25 W maximum
each), not including the integrated storage controller.
• Table 3-1 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.
