1 Safety information

Safety sign conventions

To avoid bodily injury or damage to the server or its components, make sure you are familiar with the

safety signs on the server chassis or its components.

Table 1-1 Safety signs

Sign Description

Circuit or electricity hazards are present. Only H3C authorized or professional

server engineers are allowed to service, repair, or upgrade the server.

WARNING!

To avoid bodily injury or damage to circuits, do not open any components marked

with the electrical hazard sign unless you have authorization to do so.

Electrical hazards are present. Field servicing or repair is not allowed.

WARNING!

To avoid bodily injury, do not open any components with the field-servicing

forbidden sign in any circumstances.

The RJ-45 ports on the server can be used only for Ethernet connections.

WARNING!

To avoid electrical shocks, fire, or damage to the equipment, do not connect an

RJ-45 port to a telephone.

The surface or component might be hot and present burn hazards.

WARNING!

To avoid being burnt, allow hot surfaces or components to cool before touching

them.

The server or component is heavy and requires more than one people to carry or

move.

WARNING!

To avoid bodily injury or damage to hardware, do not move a heavy component

alone. In addition, observe local occupational health and safety requirements and

guidelines for manual material handling.

The server is powered by multiple power supplies.

WARNING!

To avoid bodily injury from electrical shocks, make sure you disconnect all power

supplies if you are performing offline servicing.

1-2

Power source recommendations

Power instability or outage might cause data loss, service disruption, or damage to the server in the

worst case.

To protect the server from unstable power or power outage, use uninterrupted power supplies (UPSs)

to provide power for the server.

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.

• Place the server on a clean, stable table or floor for servicing.

• Make sure all cables are correctly connected before you power on the server.

• 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

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.

1-3

• 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.

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 and static

dissipative shoes.

• 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.

1-4

• To maintain correct airflow and avoid thermal damage to the server, install rack blanks to cover

unused rack units.

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:

• 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.

2-1

2 Preparing for installation

Prepare a rack that meets the rack requirements and plan an installation site that meets the

requirements for space and airflow, temperature, humidity, equipment room height, cleanliness, and

grounding.

Installation site requirements

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 onsite survey to make sure the cables won't affect the server rear.

The server is 1U 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 2-1.

Table 2-1

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 2-1.

Temperature and humidity requirements

To ensure correct operation of the server, make sure the room temperature and humidity meet the

requirements as described in "Appendix A Server specifications."

Equipment room height requirements

For the server to operate correctly, make sure the equipment room height meets the requirements

described in "Appendix A Server specifications."

Cleanliness requirements

Mechanically active substances buildup on the chassis might result in electrostatic adsorption, which

causes poor contact of metal components and contact points. In the worst case, electrostatic

adsorption can cause communication failure.
