1 PCI Hot Plug Utility for Windows NT
Opening the Hot Plug Utility
Use this topic only for Microsoft's Windows NT 4.0 on the HP NetServer LXr
8500 using the software utility to perform PCI Hot Plug Replacement (or Online
Replacement) operations. This topic and its subsequent topics describe how to
turn power Off and On to the PCI slots (P1-P10) using the PCI Hot Plug Utility.
For Novell's NetWare 5 NOS, go to the topics under Chapter 2 "Hot Plug
Replacement (NetWare)".
CAUTION To prevent a system crash or hang, never remove a PCI board
from a slot with power on. Always use the Hot Plug Utility to
turn power off to the Hot Plug slot before performing any
replacements.
The PCI board is only Hot Plug-capable if it has a hot plug compliant driver
available and installed on the HP NetServer. If the PCI board is not Hot Plug-
capable, remove and replace the board with the HP NetServer's power turned off.
Microsoft’s Windows NT 4.0 does not, by itself, support hot plug replacement,
but HP Configuration Assistant on the HP Navigator CD-ROM, installs the PCI
Hot Plug Utility on the NT server, along with the system software and the drivers
for some of the HP supported PCI Hot Plug boards. Through this Utility,
Windows NT 4.0 does support hot replacement of identical boards. The PCI Hot
Plug Utility is also found in the diskette library on the Navigator CD-ROM. If
using manual installation, follow the installation instructions found in the
readme.txt file to install the Utility on the NT NetServer.
The Hot Plug Utility is used to replace the PCI Hot Plug board in a four-step
process:
1. Turning power off to the PCI slot
2. Removing the PCI board
3. Replacing the PCI board
4. Turning power on to the PCI slot
The Hot Plug Utility is used to turn power off to the PCI slot before removing the
PCI board, and then after replacing the PCI board, it is used to turn power back on

to the PCI slot. Refer to the Help File for a description of the PCI Hot Plug
Utility's buttons and functions.
NOTE The Power Button is the only button required to do basic Hot
Plug Replacement.
Opening the PCI Hot Plug Utility
Use this procedure to open the PCI Hot Plug Utility in Windows NT 4.0.
NOTE If the left P (Power) LED is lit (green) in the PCI Hot Plug
Utility, the corresponding Power LED on the rear panel will be
green. This is also true for the right A (Attention) LED; that is,
if the right A (Attention) LED is lit (red) in the PCI Hot Plug
Utility, the corresponding Attention LED on the rear panel will
be amber.
1. In Windows NT 4.0, click on the Start button and then select the
Programs menu.
2. From the Programs menu, select PCI Hot Plug and then select the PCI Hot
Plug Utility.
A display similar to the example shown in Figure 1 appears.
This example has 9 slots filled with PCI boards. Slot 1 shows no board
installed and slot 2 has no hot plug compliant driver. Slots 2 to 6 and 9 to
10 all have power applied to the slot, shown by the P (Power) LED turned
on, (left P LEDs are green with Normal in status field) and are operating
normally. Slot 7 has a left P LED on (green), but also has a fault condition
indicated by the right A (Attention) LED (red), with its status field
displaying Link Fault, suggesting a corrective action. Slot 8 has a green P
LED, but has *Mixed – multiple device board (represents a multifunction
adapter) in the status field. See Help file for more information about
functions and buttons.

3. If no hot plug support appears under Board in the Utility's window
instead of the desired PCI board, one of the following conditions might be
true:
àThe PCI Hot Plug board is not supported by a hot plug compliant
software driver.
àThe software driver for the PCI Hot Plug board is not properly installed
and loaded.
See Windows NT Help for how to load drivers.
àThe PCI board may not use a driver, or the driver is defective.
NOTE If you have a board without a hot plug compliant driver in one
of the hot plug slots, the board will show up in the Utility as no
hot plug support, and the Utility will not allow you to power
down the slot.
4. Identify the physical location of the desired PCI Hot Plug board, using the
PCI Hot Plug Utility and Figures 2 and 3.
