Performing Hot-Plug Operations; Before You Begin - HP Integrity rx1620 Software Manual

4 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," and removing a card is called a "hot-plug deletion."
IMPORTANT:
PCI card hot-plug addition or deletion.

Before you begin

Review the following terms before beginning hot-plug operations:
Attention button
•
the attention button varies, depending on the server. For example, HP Integrity rx7620,
rx7640, rx8620, 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 rx3600, rx4640,
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 servers do
not have attention buttons.
• MRL latch
MRL is open, the power is turned off to the slot to prevent electrical damage to the card and
the system. HP Integrity rx7620, rx7640, rx8620, and rx8640 servers have a blue lever at the
top rear of the PCI slot. The HP Integrity rx4640 server has a black lever at the rear of the
PCI slot and a black latch at the rear of the PCI slot separator. 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 servers do not have MRLs.
Online replacement
•
Such an action requires two steps: hot-plug deletion first, and then hot-plug addition.
Therefore, some applications will notice the loss of an adapter.
Power indicator
•
on all HP Integrity servers. When this indicator is on (or flashing), the slot is powered and
should not be disturbed. When the indicator is off, you can safely add a PCI card to and
remove it from the slot.
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, complete the following
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 should be
named hpcsr.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.
Whenever 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 will be off, and the attention LED will be either
off or blinking.
HP Integrity rx1620, rx2620, rx2660, BL860c, and BL870c servers do not support
Use the attention button to initiate hot-plug operations. The location of
The MRL sensor is activated by the manual retention latch (MRL). When the
