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.

2 Description

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 equip­ment. 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.
