1Safety and Regulatory Information

For your protection, this product has been tested for conformance to various national and international

regulations and standards. The scope of this regulatory testing includes electrical and mechanical safety,

electromagnetic emissions, immunity, ESD, and hazardous materials.

Where required, certifications are obtained from third party test agencies. Certification marks, when

required, appear on the product label. In addition, various regulatory bodies require some information

under the headings below.

This product and related documentation must be reviewed for familiarization with safety markings and

instructions before operation.

WARNING The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or situation

which, if not done correctly or adhered to, could result in injury. Do not proceed beyond a

WARNING sign until the indicated conditions are fully understood and met.

CAUTION The CAUTION sign denotes a hazard. It calls attention to an operating procedure, practice,

or situation which, if not done correctly or adhered to, could damage or destroy part or

the entire product. Do not proceed beyond a CAUTION sign until the indicated conditions

are fully understood and met.

Safety Warnings

The following warnings and cautions are applicable to the System/E rack. Please observe all safe-

ty precautions and warnings.

This product has not been evaluated for connection to an IT power system (an AC distribution

system having no direct connection to earth ground)- according to IEC/EN60950.

Grounding

WARNING This is a safety class I product and has a protective earthing (grounding) terminal. There

must be an uninterruptable safety earth ground from the main power source to the

product’s input wiring terminals, power cord, or supplied cord set. Whenever it is likely

that the protection has been impaired, disconnect the power cord until the ground has

been restored.

Leakage Current

WARNING Due to types of products that can be installed in this cabinet, there is a risk of high

leakage current (3.5 mA). Reliable ground circuit continuity is vital for safe operation of

this product. To reduce the risk of electric shock, earth (ground) connection is essential

before connecting the power supply. Never operate this cabinet with the ground conductor

disconnected.

Power Limitations

CAUTION To reduce the risk of overload, do not load any single PDU with more than its rated maximum.

Cabinet Stability

CAUTION To reduce the risk of cabinet instability, attach the anti-tip feet before installing or extend-

ing any devices. Extend only one device at a time. Do not stand or sit on any extended

device. Qualified service personnel should do all non-operator servicing.

Accessories

CAUTION This product is designed for use with specific electrical accessories (i.e.,PDUs and UPSs).

The use of any other accessory is not recommended or supported.

Chapter 1 Safety and Regulatory Information

WARNING!

IMPORTANT SAFETY NOTE FOR INSTALLATION

For installations using wide-voltage-range-rated switchless power distribution units (PDU part numbers E7670A,

E7671A, E7674A, and E7676A) for connection to an uninterruptable power supply (UPS) or other AC source

• CHECK THE VOLTAGE before connecting any equipment to the PDU! Failure to check the voltage could

lead to severe equipment damage!

The voltage of the PDU receptacles equals the voltage of the receptacle to which the PDU is connected.

This voltage must be within the input voltage range of the equipment and the PDU installed in the rack.

• CHECK THE POWER SOURCE RECEPTACLE to be sure it is installed near the rack and is easily

accessible, so that the plug on the PDU power supply cord can serve as the disconnect device for the rack.

• CHECK THE TOTAL INPUT CURRENT ratings of the equipment installed in the rack to avoid overloading

the PDU or any uninterruptable power supply (UPS) to which it may be connected.

The output current rating of the PDU equals the output current rating of the power source to which the

PDU is connected, but not more than the maximum current rating (amperage) marked on the PDU.

• CHECK THE GROUNDING when installing rack-mounted products with this PDU, there is a risk of high

leakage current. Reliable ground circuit continuity is vital for safe operation of this product. To reduce

the risk of electric shock, earth (ground) connection is essential before connecting the PDU. Never

operate this PDU with the ground conductor disconnected.

WARNING!

To prevent instability leading to possible injury when moving the 2 meter racks (e.g.: A4902A, A4902D)

• Follow all stability instructions in the user guide.

• Push against the rack at the 1.6M (63 inch) height or lower.

• Exercise extra caution when moving rack sideways (racks are more stable from front to back and when full).

2Description

The HP 19-inch Electronics Industries Association (EIA) racks, options, and accessories are designed

specifically to meet the needs of HP computer and storage product customers and make installing devices

in rack mounting systems simple.

Standard Racks

Your standard HP Rack System/E is a welded steel frame with a removable rear door, casters, side panels,

leveling feet, and an anti-tip feet. Figure 2-1 shows how two basic racks might look tied together. The top

is 11-gauge, cold rolled steel. The base is 11-gauge, cold rolled steel. Threaded grounding connections are

provided near two columns at the base, and another at the top, rear.

Racks heights are measured in meters, inches, EIA units, and “U.” 1 EIA unit equals 1 U, which equals

44.45mm (1.75 in). The columns are numbered EIA units. The U41 rack is 1.96m, or 41 EIA units.

Internally, rails and slides that hold your equipment lock into slots in the vertical mounting columns and are

sometimes fastened to the columns with screws. Column faces are numbered for easy placement of equip-

ment. An extendable top adds 8U of height. Tie-together kits allow easy, secure mating of 1.96m cabinets.

Tied together racks with the accessories are shown in Figure 2-2.

The following parts are standard with

every System/E rack.

Top Cap and Forehead

The top cap is 16-gauge, cold rolled steel

(CRS). The top cap and forehead are

attached at the factory. The top of the

rack incorporates a ventilation path

through the roof of the rack and a

convection current heat exit for the heat

generated by the installed equipment.

Chapter 2 Description

Heavy-duty Columns

The rack columns are a folded design made

of 12-gauge rolled steel that supports up to

2000 lbs. Running up the inside of the fold

are square mounting slots for the rails,

slides, and screw holes for securing the

rails. The hole placement conforms to EIA

standards.

The mounting columns are welded into

place at the bottom corners of the frame,

and bolted at the top. The columns accept

supporting rails into mounting slots. Each

support rail pair attaches between the

front and rear columns. The equipment is

then mounted on the support rails.

The mounting columns have pre-

positioned threaded inserts pressed into

the hexagonal accessories holes in the

front faces of the columns. The inserts are

positioned to accept tie brackets, hinges,

latches, and PDUs.

Anti-Tip Feet

A front and rear anti-tip foot are included

with HP Rack Systems to provide additional

stability. The anti-tip feet must be attached

before installing, servicing, or removing any

equipment. Do not remove the anti-tip feet

unless the optional tie-together kit is used

with multiple racks.

WARNING The stability work sheets should be used whenever a new system is configured, or a

change to a system is made, to assure rack stability.

Heavy-Duty Casters

Each System/E is provided with four,

7.6 cm (3 in) diameter, smooth rolling,

heavy-duty urethane casters to facilitate

moves over short distances. The casters

are rated at 454.5 kg (1000 lbs) per

caster.

CAUTION A fully loaded cabinet’s maximum gross weight of 995 kg (2188 lbs) can overload a raised floor.

Leveling Feet

Four adjustable leveling feet come with

the rack for stability and leveling.

Levelers are located in each corner to

level and stabilize the rack. For maxi-

mum accuracy, use a level while adjust-

ing the feet.

Rear Door

The rear door comes installed from the

factory. Standard is a right-opening, per-

forated rear door with a lockable slam

latch and sheetmetal catch providing

ventilation and security. The rear door

can be mounted to open from either the

left or the right. They are perforated for

maximum airflow. They lift on and off

their hinges when open to about 45

degrees. The 1.96 m door weighs 11.8

kg (26 lbs). The 1.6 m rear door weighs

9.1 kg (20 lbs). The 1.25 m rear door

weighs 7.7 kg (17 lbs).
