PCI/PCI-X/PCIe Card Slot
The server has eight public, hot-pluggable PCI/PCI-X/PCIe slots and two private core I/O slots.
Each slot has an attention LED that serves two purposes (Figure 13). It indicates a potential problem
with the slot that requires immediate attention. Additionally, the LED can function as a locator used
to identify a particular PCI/PCI-X/PCIe slot. You can activate the locator functionality using various
software utilities.
CAUTION: Private core I/O slots are not hot-pluggable. Do not remove the cards in these slots
without first powering off the server and unplugging the power cords.
