Installing Hardware Options, Hot-Pluggable PCI Hot Plug I/O Expansion Boards The ProLiant DL760 G2 server supports PCI Hot Plug. PCI Hot Plug and the operating system of the server work together to allow the following hot-plug actions: • Hot-replace-Allows you to replace a failed expansion board with an identical expansion board without powering down the server. • Hot-add-Allows you to install new PCI/PCI-X expansion boards in previously empty slots without powering down the server under some operating systems. • Hot-upgrade-Allows you to replace an expansion board with a different expansion board without powering down the server. PCI Hot Plug is backward-compatible, although system components fit into one of two categories: hot-plug aware or non-hot-plug aware. The following three components are required in the server for complete PCI Hot Plug capability: • PCI Hot Plug system hardware (available in this server) • Operating system with PCI Hot Plug support (support levels vary) • PCI Hot Plug device drivers (available from operating system vendors, the SmartStart CD, HP website, and some individual hardware vendors) WARNING: To reduce the risk of personal injury from hazardous energy or damage to the equipment when working on energized servers: • Remove all watches, rings, and any other loose-fitting jewelry. • Avoid the use of conductive tools that could bridge live parts. IMPORTANT: If any of the three required components are non-hot-plug aware, the system is fully functional but is not PCI Hot Plug-capable. 5-40 HP ProLiant DL760 Generation 2 Server User Guide
