1 Performing Hot-Plug Operations
This chapter describes adding and removing PCI cards on HP Integrity servers. Adding a card to
your system is called a hot-plug addition. Removing a card is called a hot-plug deletion.
IMPORTANT:
HP Integrity rx2660, rx2800 i2, BL860c, BL870c, and BL8x0 i2 servers do not
support PCI card hot-plug addition or deletion.
Before you begin
Review the following terms before beginning hot-plug operations:
Attention button
Use the attention button to initiate hot-plug operations. The location of the attention
button varies, depending on the server. For example, HP Integrity rx7640 and rx8640
servers have a white bell-shaped image button, located at the top rear of the PCI slot.
To access, remove the button cover. HP Integrity rx6600, BL860c, and BL870c servers
have a maroon-colored button on the top of the PCI slot separator, just below the manual
retention latch (MRL). HP Integrity Superdome sx2000 servers have attention buttons.
MRL latch
The MRL sensor is activated by the manual retention latch (MRL). When the MRL is
open, the power is turned off to the slot to prevent electrical damage to the card and
the system. HP Integrity rx7640 and rx8640 servers have a blue lever at the top rear
of the PCI slot. HP Integrity rx3600 and rx6600 servers have a black latch on top of
the PCI slot that you must press down then pull upward to activate. HP Integrity
Superdome sx2000 servers have MRLs.
Online
replacement
Windows does not natively support I/O card online replacement. Such an action
requires two steps: first, hot-plug deletion, and then hot-plug addition. Therefore, some
applications might notice the loss of an adapter.
Power indicator
The green power indicator LED is located at the top of the slot separator on all HP
Integrity servers. When this indicator is on (or flashing), the slot is powered and must
not be disturbed. When the indicator is off, you can safely add a PCI card to and
remove it from the slot.
TIP:
If you perform hot-plug additions or deletions on the HP Integrity server and you do not
achieve the expected results, verify installation of the driver.
To verify driver installation on HP Integrity mid-range or high-end servers, follow these steps:
1.
Launch the Windows Device Manager and expand the system devices. Right-click
HPCSR
OpRegion Driver
. Then click
Properties
and go to the
Driver
tab. The driver is named
hpcsr2.sys
, Version 1.1.0.0, dated 6/13/03. If it is not, you must update the driver.
2.
Open the Online Reference page on the desktop.
3.
Click
OEM Drivers
.
4.
In the Description column, click
HP (Hotplug) Region Driver
. This starts the hot-plug driver
update.
5.
Click
Yes
to install the driver.
When you activate a PCI slot that is already powered on, its solid orange attention LED light turns
on, indicating an error. Also, if you try to activate a slot that is not occupied, it flashes the attention
LED to identify that slot. This is expected behavior, and not an error. When the PCI slot is powered
off, the power LED for that slot is off, and the attention LED is either off or blinking.
