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.
• 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 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.
1. Maximum of 2 of any card whose maximum power exceeds 15W.
2. Refer to the expansion card documentation to ensure that the maximum power does not exceed
15W.
