Remove the entire cover for full access to the processor baseboard and I/O
baseboard.
Remove the panel at the rear of the top cover for access to the four 64-bit
PCI slots on the I/O baseboard. These slots support PCI Hot Plug, and so

operating. The server can operate safely for long periods with this panel
removed.
