Installation safety recommendations
To avoid bodily injury or damage to the server, read the following information carefully before you
operate the server.
General operating safety
To avoid bodily injury or damage to the server, follow these guidelines when you operate the server:
•Only H3C authorized or professional server engineers are allowed to install, service, repair,
operate, or upgrade the server.
•Make sure all cables are correctly connected before you power on the server.
•Place the server on a clean, stable table or floor for servicing.
•To avoid being burnt, allow the server and its internal modules to cool before touching them.
Electrical safety
WARNING!
If you put the server in standby mode (system power LED in amber) with the power on/standby
button on the front panel, the power supplies continue to supply power to some circuits in the server.
To remove all power for servicing safety, you must first press the button, wait for the system to ente
r
standby mode, and then remove all power cords from the server.
To avoid bodily injury or damage to the server, follow these guidelines:
•Always use the power cords that came with the server.
•Do not use the power cords that came with the server for any other devices.
•Power off the server when installing or removing any components that are not hot swappable.
Rack mounting recommendations
To avoid bodily injury or damage to the equipment, follow these guidelines when you rack mount a
server:
•Mount the server in a standard 19-inch rack.
•Make sure the leveling jacks are extended to the floor and the full weight of the rack rests on the
leveling jacks.
•Couple the racks together in multi-rack installations.
•Load the rack from the bottom to the top, with the heaviest hardware unit at the bottom of the
rack.
•Get help to lift and stabilize the server during installation or removal, especially when the server
is not fastened to the rails. As a best practice, a minimum of two people are required to safely
load or unload a rack. A third person might be required to help align the server if the server is
installed higher than check level.
•For rack stability, make sure only one unit is extended at a time. A rack might get unstable if
more than one server unit is extended.
•Make sure the rack is stable when you operate a server in the rack.
•To maintain correct airflow and avoid thermal damage to the server, use blanks to fill empty rack
units.

ESD prevention
Electrostatic charges that build up on people and tools might damage or shorten the lifespan of the
system board and electrostatic-sensitive components.
Preventing electrostatic discharge
To prevent electrostatic damage, follow these guidelines:
•Transport or store the server with the components in antistatic bags.
•Keep the electrostatic-sensitive components in the antistatic bags until they arrive at an
ESD-protected area.
•Place the components on a grounded surface before removing them from their antistatic bags.
•Avoid touching pins, leads, or circuitry.
•Make sure you are reliably grounded when touching an electrostatic-sensitive component or
assembly.
Grounding methods to prevent electrostatic discharge
The following are grounding methods that you can use to prevent electrostatic discharge:
•Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
•Take adequate personal grounding measures, including wearing antistatic clothing, static
dissipative shoes, and antistatic gloves.
•Use conductive field service tools.
•Use a portable field service kit with a folding static-dissipating work mat.
Cooling performance
Poor cooling performance might result from improper airflow and poor ventilation and might cause
damage to the server.
To ensure good ventilation and proper airflow, follow these guidelines:
•Install blanks if the following module slots are empty:
{Drive bays.
{Fan bays.
{PCIe slots.
{Power supply slots.
•Do not block the ventilation openings in the server chassis.
•To avoid thermal damage to the server, do not operate the server for long periods in any of the
following conditions:
{Access panel open or uninstalled.
{Air baffles uninstalled.
{PCIe slots, drive bays, fan bays, or power supply slots empty.
•Install rack blanks to cover unused rack spaces.
Battery safety
The server's system board contains a system battery, which is designed with a lifespan of 5 to 10
years.
If the server no longer automatically displays the correct date and time, you might need to replace
the battery. When you replace the battery, follow these safety guidelines:
4
•Do not attempt to recharge the battery.
•Do not expose the battery to a temperature higher than 60°C (140°F).
•Do not disassemble, crush, puncture, short external contacts, or dispose of the battery in fire or
water.
•Dispose of the battery at a designated facility. Do not throw the battery away together with other
wastes.

Preparing for installation
Prepare a rack that meets the rack requirements and plan an installation site that meets the
requirements of space and airflow, temperature, humidity, equipment room height, cleanliness, and
grounding.
Rack requirements
IMPORTANT:
As a best practice to avoid affecting the server chassis, install power distribution units (PDUs) with
the outputs facing backwards. If you install PDUs with the outputs facing the inside of the server,
please perform an onsite survey to make sure the cables won't affect the server rear.
The server is 2U high. The rack for installing the server must meet the following requirements:
•A standard 19-inch rack.
•A clearance of more than 50 mm (1.97 in) between the rack front posts and the front rack door.
•A minimum of 1200 mm (47.24 in) in depth as a best practice. For installation limits for different
rack depth, see Table 2.
Table 2 Installation limits for different rack depths
Rack depth Installation limits
1000 mm
(39.37 in)
•The H3C cable management arm (CMA) is not supported.
•A clearance of 60 mm (2.36 in) is reserved from the server rear to the rear rack
door for cabling.
•The slide rails and PDUs might hinder each other. Perform onsite survey to
determine the PDU installation location and the proper PDUs. If the PDUs hinder
the installation and movement of the slide rails anyway, use other methods to
support the server, a tray for example.
1100 mm
(43.31 in)
Make sure the CMA does not hinder PDU installation at the server rear before
installing the CMA. If the CMA hinders PDU installation, use a deeper rack or change
the installation locations of PDUs.
1200 mm
(47.24 in)
Make sure the CMA does not hinder PDU installation or cabling. If the CMA hinders
PDU installation or cabling, change the installation locations of PDUs.
For detailed installation suggestions, see Figure 1.
