PCI Hot Plug Cabling
Compaq ProLiant DL580 servers support PCI Hot Plug technologies.
Instructions for ensuring that your system is PCI Hot Plug capable are
provided in Chapter 6, “PCI Hot Plug Technology.”
Your server includes four PCI expansion slots that are hot-pluggable and two
PCI expansion slots that are non-hot-pluggable. As you begin to install
expansion boards, and before configuring and powering up the server for the
first time, allow some slack in cables that are used to connect PCI Hot Plug
expansion boards to system board or other connectors. Excessively tight
cabling configurations can interfere with hot-plug operations that are
performed while the server is active.
IMPORTANT:
Remember that the cable from any expansion board cannot be safely
removed if the slot for that board has not been powered down by either the PCI Hot Plug
button or the operating system.
IDE Media Cabling
Compaq ProLiant DL580 servers include an integrated IDE controller to
control the high-speed, low-profile IDE CD-ROM drive. No additional cabling
is required.
Power Cabling
WARNING:
Before removing the top access panel, make sure that the server is
powered down or in Standby mode, and that all power connections are
disconnected from the server. The system power in Compaq ProLiant DL580
servers does not completely shut off from the front panel Power On/Standby
switch. The two positions of the switch function as On and Standby modes,
rather than as On and Off modes. The Standby position cuts power from most of
the electronics and the drives while portions of the power supply and some
internal circuitry remain active.
Consequently, to remove all power from the system, it is necessary to
disconnect all power cords from the server in order to remove power completely
from the system.
