Installing Hardware Options, Hot-Plug
Adding a PCI Hot Plug Expansion Board
The PCI/PCI-X slots of the I/O board are hot-plug-capable and support a variety of
industry-standard expansion boards. For a list of supported I/O expansion boards,
refer to the QuickSpecs for ProLiant DL740 servers:
www.hp.com
CAUTION: Do not attempt this hot-plug operation if your operating system does not
provide PCI/PCI-X Hot Plug support or if you do not have the appropriate drivers
installed. Failure to properly execute a hot-plug operation can halt your system.
Refer to Figure 5-19, Figure 5-20, and Table 5-6 for definitions of the PCI Hot Plug
LEDs. To add a PCI/PCI-X expansion board into PCI Hot Plug slots 1 through 6:
1. Open the top access panels.
2. If the PCI Hot Plug green LED is on, power down the slot by pressing the PCI
Hot Plug button corresponding to the slot or by using a PCI Hot Plug software
application. Wait until the flashing green LED is off. For more information about
PCI Hot Plug LEDs, refer to “PCI Hot Plug LED Indicators” earlier in this
chapter.
CAUTION: To avoid system power-down and subsequent data loss, do not
open the slot release lever unless the green PCI Hot Plug LED of the slot is off.
NOTE: To cancel this action, press the PCI Hot Plug button again within five seconds of
the first press.
3. Disconnect the cables to the PCI/PCI-X board when the green LED of the slot is
off.
