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.
