Electrostatic Discharge CAUTION: Connect to ground with a wrist strap. Connection can be made to any grounded metal assembly in the cabinet. Both you and the electronic devices must be grounded to avoid static discharges that can cause damage. CAUTION: Observe all ESD safety precautions before attempting the following procedures. Failure to follow ESD safety precautions could result in damage to the server. HP systems and peripherals contain assemblies and components that are sensitive to electrostatic discharge (ESD). Carefully observe the precautions and recommended procedures in this manual to prevent component damage from static electricity. Take these precautions: • Prepare an ESD-safe work surface large enough to accommodate the various assemblies handled during the upgrade. Use a grounding mat and an anti-static wrist strap, such as those included in the ESD Field Service Kit (A3024-80004). • The anti-static bag cannot function as a static dissipating mat. Do not use the anti-static bag for any other purpose than to enclose a product. • Treat all assemblies, components, and interface connections as static-sensitive. • When unpacking cards, interfaces, and other accessories that are packaged separately from the system, keep the accessories in the conductive plastic bags until they are ready to be installed. • Avoid working in carpeted areas, and keep body movement to a minimum while installing accessories. Powering down Hardware Components and Powering on the Server When you remove and replace hardware, you may need to power off hardware components as part of the remove and replace procedure. This section gives details on how to power off and on hardware components. Powering Off Hardware Components To power off individual components or the entire cabinet: 1. Log in to the management processor (MP) of the server. 2. If the component you will power off is assigned to an nPartition, then use the Virtual Front Panel (VFP) to view the current boot state of the nPartition. HP-UX on the nPartition must be shut down before you power off any of the hardware assigned to the nPartition. See Appendix E "Operating System Boot and Shutdown". When you are certain the nPartition is not running HP-UX, you can power off components that belong to the nPartition. Refer to Appendix E "Operating System Boot and Shutdown" for details on determining the nPartition boot state and shutting down HP-UX. 3. Access the MP Command menu. From the MP Main menu, enter CM to access the Command menu. 4. Use the MP Command menu PS command to check details about the hardware component you plan to power off. The PS command enables you to check the status of the cabinet, system backplane, MP core I/O, PCI power domains-or bricks-in the I/O card cage, and cells.

Electrostatic Discharge
CAUTION:
Connect to ground with a wrist strap. Connection can be made to any grounded
metal assembly in the cabinet. Both you and the electronic devices must be grounded to avoid
static discharges that can cause damage.
CAUTION:
Observe all ESD safety precautions before attempting the following procedures.
Failure to follow ESD safety precautions could result in damage to the server.
HP systems and peripherals contain assemblies and components that are sensitive to electrostatic
discharge (ESD). Carefully observe the precautions and recommended procedures in this manual
to prevent component damage from static electricity.
Take these precautions:
•
Prepare an ESD-safe work surface large enough to accommodate the various assemblies
handled during the upgrade. Use a grounding mat and an anti-static wrist strap, such as
those included in the ESD Field Service Kit (A3024-80004).
•
The anti-static bag cannot function as a static dissipating mat. Do not use the anti-static bag
for any other purpose than to enclose a product.
•
Treat all assemblies, components, and interface connections as static-sensitive.
•
When unpacking cards, interfaces, and other accessories that are packaged separately from
the system, keep the accessories in the conductive plastic bags until they are ready to be
installed.
•
Avoid working in carpeted areas, and keep body movement to a minimum while installing
accessories.
Powering down Hardware Components and Powering on the Server
When you remove and replace hardware, you may need to power off hardware components as
part of the remove and replace procedure.
This section gives details on how to power off and on hardware components.
Powering Off Hardware Components
To power off individual components or the entire cabinet:
1.
Log in to the management processor (MP) of the server.
2.
If the component you will power off is assigned to an nPartition, then use the Virtual Front
Panel (VFP) to view the current boot state of the nPartition.
HP-UX on the nPartition must be shut down before you power off any of the hardware
assigned to the nPartition. See Appendix E “Operating System Boot and Shutdown”.
When you are certain the nPartition is not running HP-UX, you can power off components
that belong to the nPartition.
Refer to Appendix E “Operating System Boot and Shutdown” for details on determining
the nPartition boot state and shutting down HP-UX.
3.
Access the MP Command menu.
From the MP Main menu, enter
CM
to access the Command menu.
4.
Use the MP Command menu
PS
command to check details about the hardware component
you plan to power off.
The
PS
command enables you to check the status of the cabinet, system backplane, MP core
I/O, PCI power domains—or bricks—in the I/O card cage, and cells.
