Warning and caution messages
WARNING! To reduce the risk of personal injury or damage to equipment, heed all warnings
and cautions throughout the installation instructions.
WARNING! To reduce the risk of personal injury or damage to the equipment, be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING! To reduce the risk of personal injury or equipment damage when unloading a rack:
• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack
can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and might
become unstable when being moved on its casters.
• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always
handle the rack from both sides.
WARNING! The enclosure is very heavy. To reduce the risk of personal injury or damage to
the equipment:
• Observe local occupational health and safety requirements and guidelines for manual material
handling.
• Remove all hard drives before installing or moving the enclosures.
• Use caution and get help to lift and stabilize enclosures during installation or removal,
especially when the enclosure is not fastened to the rack.
• Never stack an enclosure on top of another enclosure.
• Never place equipment on top of an enclosure.
• Never place an enclosure on a surface that cannot support up to 163.3 kg (360.0 lb).
WARNING! To reduce the risk of personal injury or damage to the equipment, you must
adequately support enclosures during installation and removal.
WARNING! Always use at least two people to lift an enclosure into the rack. If the enclosure
is being loaded into the rack above chest level, a third person must assist with aligning the
enclosure with the rails while the other two people support the weight of the enclosure.
WARNING! Be sure to install enclosures starting from the bottom of the rack and work your
way up the rack.
WARNING! To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Never reach inside the chassis while the system is connected to a power source.
• Perform service on system components only as instructed in the user documentation.
WARNING! A risk of electric shock from high leakage current exists. Before connecting the
AC supply to the power enclosures, be sure that the electrical outlets are properly grounded
(earthed).
Safety precautions 9
CAUTION: Always be sure that equipment is properly grounded and that you follow proper
grounding procedures before beginning any installation procedure. Improper grounding can result
in ESD damage to electronic components. For more information, see “Preventing electrostatic
discharge” (page 7)
CAUTION: When performing non-hot-plug operations, you must power down the server blade
and/or the system. Use caution when performing other operations, such as hot-plug installations
or troubleshooting.
CAUTION: Protect the equipment from AC power fluctuations and temporary interruptions with
a regulating facility UPS device. This device protects the hardware from damage caused by
power surges and voltage spikes and keeps the system in operation during a power failure.
Precautions for maintaining and servicing products
To reduce the risk of electric shock or damage to the equipment when installing, maintaining, or
servicing products, observe the following precautions:
• Some products contain power supplies that are capable of producing hazardous energy
levels. Refer to the documentation included with your product to determine whether it contains
these power supplies. The installation of internal options and routine maintenance and
service of this product should be performed by individuals who are knowledgeable about
the procedures, precautions, and hazards associated with equipment containing hazardous
energy levels.
• Allow the product to cool before removing covers and touching internal components.
• Do not use conductive tools that could bridge live parts.
• Remove all watches, rings, or loose jewelry when working in hot-plug areas of an energized
server and storage products.
• Do not attempt to defeat safety interlocks (where provided).
• Some products have covers or doors to access hot-plug components and may allow access
to hazardous energy circuits or moving fans.
◦ The doors should remain locked during normal operation.
OR
• The product should be installed in a controlled access location where only qualified personnel
have access to the product.
• Power down the equipment and disconnect all AC power cords before removing any access
covers for non-hot-plug areas.
• Do not replace non-hot-plug components while power is applied to the product. First, shut
down the product and disconnect all AC power cords.
• Do not exceed the level of repair specified in the procedures in the product documentation.
All troubleshooting and repair procedures are detailed to allow only subassembly or
module-level repair. Because of the complexity of the individual boards and subassemblies,
do not attempt to make repairs at the component level or to make modifications to any printed
wiring board. Improper repairs can create a safety hazard.
• Verify that the AC power supply branch circuit that provides power to the rack is not
overloaded. This will reduce the risk of personal injury, fire, or damage to the equipment.
The total rack load should not exceed 80 percent of the branch circuit rating. Consult the
electrical authority having jurisdiction over your facility wiring and installation requirements.
10 Removal and replacement procedures
Power cords
To reduce the risk of electric shock or damage to the equipment:
• Use an approved power cord. If you have questions about the type of power cord to use,
contact your Hewlett Packard Enterprise authorized service provider.
• If you have not been provided with a power cord for your product or for any AC-powered
option intended for your product, purchase a power cord that is approved for use in your
country.
• You must use a power cord rated for your product and for the voltage and current marked
on the electrical ratings label of the product. The voltage and current rating of the cord must
be greater than the voltage and current rating marked on the product.
• Do not place objects on AC power cords or cables. Arrange them so that no one may
accidentally step on or trip over them.
• Do not pull on a cord or cable. When unplugging from the electrical outlet, grasp the cord
by the plug.
• Make sure that the total ampere rating of all products plugged into an extension cord or
power strip does not exceed 80 percent of the ampere ratings limit for the extension cord or
power strip.
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at
all times.
Power supplies
Hot-plug power supplies are not designed to be removed or installed with AC power connected
to the power supply. To reduce the risk of electric shock or damage to the equipment when
handling hot-plug power supplies:
• Install the power supply before connecting the power cord to the power supply.
• Unplug the power cord before removing the power supply from the product.
• If the system has multiple sources of power, you must unplug all AC power cords from the
power supplies to completely disconnect power from the system.
Verify that the external power source connected to your product matches the type of power source
indicated on the electrical ratings label. If you are not sure of the type of power source required,
consult your authorized service provider or local power company.
Powering off disk enclosures
IMPORTANT: Always power off disk enclosures after controller enclosures and servers.
IMPORTANT: When installing a hot-pluggable component, such as a disk drive, it is not
necessary to power down the enclosure.
To power off a disk enclosure:
1. Power off any attached servers. For more information, see the server documentation.
2. Power off the controller enclosure (if included in the configuration.) For more information,
see the controller enclosure documentation.
3. Disconnect power cords.

Observe the following best practices before powering on the enclosure for the first time:
• Complete the server, controller, or controller enclosure installation. For more information,
see the server, controller, or controller enclosure user documents.
• Install the disk enclosures.
• Install disk drives in the disk enclosures so that the connected host controller can identify
and configure them at power on.
• Connect the SAS cables and power cords to the enclosure.
Power on procedures
1. Connect the enclosure to a live power source.
NOTE: There is no power on/standby button. Power flows to the enclosure immediately
upon connecting to a live power source.
2. Once power is applied to the power supplies, the enclosure starts running.
The power on LED turns solid green.
3. Wait a few minutes for the disk enclosures to complete their startup routines.
CAUTION: If power is applied to the server before the disk enclosures complete their
startup routine, the server might not properly discover the storage.
4. Apply power to the controller enclosure (if included in the configuration).
5. Power on (or restart) the server with access to the disk enclosures, start the operating system,
and log on as administrator.
CAUTION: When you power on the server, the monitor might display a “New Hardware
Found” message. Cancel out of this window to prevent the installation of unsupported
software.
6. Verify that each component is operating properly.
