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).

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.

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 pre­positioned 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.

Accessories

To complement the functionality of your standard rack, a wide assortment of accessories is available.
Accessories shown below are a quartz gray color and are also available in a graphite color (denoted by an
asterisk*). These accessories allow you to complete your system with only the items you require while
providing you a certified and tested solution.

PDUs

The HP Power Distribution Units (PDUs) are designed to provide flexibility for your power requirements.
To provide power to the rack, a PDU must be ordered as an accessory. There are different types of PDUs
available for different voltages. All input leads from the mains, except safety ground, are interrupted in the
event of a short circuit.

The PDUs can be mounted both vertically and horizontally on the rear rack columns, depending on your
rack configuration. If you purchased the bundle containing both the 10 and 16-amp products, you can con­nect them to each other with the provided cord. Use the EIA holes for horizontal mounting, and the acces­sory holes for vertical mounting.

Each rack can be equipped with up to six PDUs. Each PDU must be purchased as an accessory. Figure 2-3
shows some PDU Mounting schemes.

Front Door

Standard is a right-opening, perforated front door with a lockable slam latch and sheet metal catch providing
ventilation and security. The rear door can be mounted to open from either the left or the right.

Support Rails

Some equipment is supported in the rack by support rails running from front to back. The rails are
screwed to the vertical columns

Only after securing a pair of rails with screws can equipment be installed.
The mounting slots in the columns are positioned to make support rail placement convenient in EIA units.

Rack Lifting Hooks

Four lifting hooks can be fitted to the top of the rack. Together, they can support the weight of a rack
loaded to maximum recommended gross weight. Each hook is capable of supporting 248.6 kg (547 lbs).
Maximum recommended gross weight is 995 kg (2188 lbs).

Side Panels

Sectioned side panels are injection molded PC-ABS plastic and come in two sizes: 9 EIA unit and 8 EIA
unit. All three racks use the 9 EIA unit panel at the bottom, and 8 EIA unit panels for the remainder. Pull
out-and-off side panels allow fast and easy access from either side for installation, servicing, and removal of
equipment.

Filler Panels

To ensure adequate cooling in racks using extractor fans, all unused front panel space must be covered
with blank filler panels and the rear door must be closed.

Filler panels are 1 U in height, and snap on and off without tools or mounting hardware.

Keyboard Tray

A pullout keyboard tray is available. The keyboard tray can be installed with either a sitting, or standing
operator in mind. The tray is mounted on rollers that allow it to be retracted or extended.

Chapter 2 Description

Monitor Mount Kit

An optional universal monitor rack mount kit is available. A shelf that can be mounted for a sitting, or
standing operator. The shelf has channels cut from it that accommodate the securing clamps.

Universal Mounting Rails

Some equipment is supported by and anchored to universal rails made of cold rolled steel that weigh 2.7
kg (6 lbs) and support up to 68.2 kg (150 lbs). Hollow metal blocks have lips that fit into the support rails
and holes for screws. The blocks are slid into contact with the equipment, and are then attached to the rail
with screws.

Spacers are fit between the rails and the columns.

Ballast

Ballast is available in 30 lb. and 120 lb. kits, and may be required when using slide-mounted products
and/or keyboard/ work surface products. Use the stability work sheets to determine ballast requirements.

CAUTION Do not ship racks with ballast installed.
CAUTION Always mount ballast in the rear of the rack.

NOTE The anti-tip feet are not a substitute for ballast.

3 Installation Guidelines

The following section defines the floor loading requirements, and set up guidelines.

Floor Space and Loading

Observe floor loading requirements (especially raised floors) and ensure adequate space before moving
your Rack System/E, and all safety items while moving.

At maximum gross weight, the floor must be able to support 677-kg/ sq cm (2000 lb./sq in).
WARNING It is the customer’s responsibility to determine the floor loading capacities at the

installation site, and for the entire route when moving. Failure to do so could
result in personal injury and/or equipment damage.

Because the weight is concentrated on the four casters, a maximum weight rack requires a reinforced
floor. Hewlett-Packard recommends removing components and moving them separately when moving a
rack over a floor (especially a raised floor) of unknown capacity.

WARNING Heavily loaded racks may require reinforced tiles or a sub structure on a

raised floor.

Rack Space

Select a location for the rack that will afford adequate space for the doors to open freely, and slide-mount­ed equipment to be extended.

Door Clearance

The rack requires a minimum of 600 mm (23.6 in) for rear door clearance. The same amount is required
for the front door, if installed.

Cable Access

The base of the rack stops 100 mm (3.9 in) short of the rear door, providing an access path for power and
signal cables.

Installing Equipment in the Rack

Two main considerations should be kept in mind when installing equipment into racks: weight and balance
(especially for slide-mounted equipment), and heat dissipation. This section includes some worksheets for
calculating the weight and balance for slide mounted products and an optional work surface.

Always install equipment from the bottom to the top to keep the center of gravity as low as possible. The
order that you put them should be based on how well a given piece of equipment promotes or impedes
heat removal, if heat removal is an issue.

Ventilation and Heat Dissipation

Most HP products draw air in through the front and exhaust out the back. The Rack System/E is designed
to accommodate this cooling scheme. Any trapped heat will be convected through the top perforations.

Chapter 3 Installation Guidelines

Figure 3-1. Air Flow through the System/E

When the proper system is installed, internal temperature rise is typically less than 15C (27F) over

ambient temperature.

NOTE Hewlett-Packard recommends that the customer monitor the internal temperature of the

rack. The internal temperature should not exceed the heat rating of any installed instruments.

Installing Rail Mounted Equipment into the Rack

Equipment is installed by first attaching equipment rails between both front and rear columns, as shown in
Figure 3-2. A clip nut goes behind the rail and a spacer block at the top hole the EIA unit. This is the same
hole the screw lines up with.

Figure 3-2. Attaching Rail to Column

Chapter 3 Installation Guidelines

Stability

For stability, the sum of the moments above the 32 U critical height must be less than the sum of the
moments below the 32 U critical height. As long as the weight above critical height is less than the weight
below, the moments will most likely cancel. The center of gravity of the cabinet itself is well below the
critical height, adding stability. Because the racks are deeper than they are wide, they are more stable from
front to back, than side to side, as shown in Figure 3-4.

TAN 10 degees = 11.0/Z
Z = 11.0/TAN 10 degrees
Z = 62.4 in (1.58 m)

As you can see from illustration on 3.3, 1.25 m racks are “unconditionally” stable, and 1.6 m racks are very
difficult to overload, as they extend only 1 U above the critical height.

For 1.6 m and 1.96 m racks, add the weights of the units which have centers of gravity above 32 U, then
compare the sum of the weights below 32 U. Always configure racks for the majority of the weight below
the critical height.

Assumptions/Disclaimers

The center of gravity for the racks is found in the geometric center. Centers of gravity of products is assumed
to be at their Front/Back, Left/Right centers. Grossly imbalanced equipment will void the calculations. If
doubt exists, stability should be verified by tip-over testing, per UL-1950, SECTION 4.1.

WARNING The stability information/work sheets in this manual are for stationary racks. When moving

a rack, take additional precautions to prevent tipping, including the following.

• Confirm that equipment is installed according to the users guide.

• Be especially careful with fully loaded racks, which have more momentum when moving, or top loaded
racks, which have a higher center of gravity.

• Before any movement, check that any movable items mounted in the rack are fully pushed in and
mechanically secured.

• Loosen the bolts securing the anti-tip feet and raise both feet. Tighten the bolts in the raised position.

• Move SLOWLY over any obstructions such as power cords, elevator thresholds, cracks in sidewalk,
tile/carpet interfaces, etc., which can catch the front wheels and start tipping.

• STOP PUSHING IMMEDIATELY if any tipping occurs and allow the rack to right itself.

• Negotiate obstacles one wheel at a time, rather than two wheels at a time, to minimize the possibility of
tipping.

• Keep speed SLOW ‹ heavy racks are hard to start moving and hard to stop.

• Exercise common sense and caution when moving ANY equipment configuration.

Slide-Mounted Products

Slide-mounted products and work surface/keyboard products need weight and balance calculations per­formed to determine the need for ballast to reduce the risk of cabinet instability. The worksheets for both
are provided on the following page. If both slide-mounted and work surface/keyboard products are being
used, calculate both and add the results.

To reduce the risk of rack instability when operator serviceable, slide-mounted products are installed, use
the following worksheet to determine the need for additional counterweight ballast. If there are no operator
serviceable, slide-mounted products in the rack, this worksheet can be ignored.

An operator serviceable, slide mounted product is defined as any product which can be extended from the
rack for servicing without requiring the use of any tool. A product requiring the use of a tool to facilitate
servicing or extending the product is the definition of trained service personnel serviceable only. When a
trained service personnel serviceable only product is extended, the use of the anti-tip feet is required, but
counterweight ballast is not. See Figure 3-5.

Also note that some HP products preclude the use of counter weight, due to their mounting depth. These
products are appropriately labeled, and require that the rack anti-tip feet are installed before the slider
product is pulled out. Also, it is recommended that no more than one slider product be pulled out at one
time, to ensure the greatest possible stability.

NOTE No slide mounted products may be extended at the same time the work surface is in use.

Figure 3-5. Moment Illustration for Slide Mounted Products

Weight and Balance Worksheet:

1. Total the weight of operator serviceable slide-mounted products:
A=________lbs; B=________lbs; C=_________lbs; D=_________ lbs; A + B + C + D=____________________________

2. Total the weight of all fixed and trained service personnel serviceable products:
a=________lbs; b=_________lbs; c=__________lbs; d=_________ lbs; a + b + c + d=____________________________

3. Calculate the moment for both the operator serviceable slide-mounted products (M1) and the fixed and trained
service personnel serviceable products (M2) totals from above:

M1 M2

(A + B + C + D ...) * 1.25 ft -97.2 ft-lbs + (a + b + c + d + ....) * 1.00 ft

M1 = Moment on rack with all operator serviceable slide mounted products extended.
M2 = Moment of all fixed and trained personnel serviceable slide mounted products and rack.
M2 moment calculations assume a 1.00 ft center of gravity for installed products.

If M1 is less than or equal to M2, no additional counter weight is needed.
If M1 is greater than M2, use the formulas below to determine the required counter weight.

Force (in lbs) = M1- M2 ft-lbs / 2.46 = amount of force required at 2.46 ft
X = Force lbs / 30 lbs = number of C2790A 30 lbs ballast kits to install, where “X” is rounded up to the

next highest integer, e.g., 1.2 = 2 ballast kits.

Weight and Balance Worksheet

1. Maximum extended length of the keyboard/work surface product:
D=_________ft

2. Total the weight of all fixed and trained service personnel serviceable slide-mounted products:
a=________lbs; b=_________lbs; c=_________lbs; d=_________ lbs; . . .

3. Calculate the moment for both the (M1) and the fixed and trained service personnel serviceable slide-mounted
products (M2) totals from above:

Model M1 M2

1.25 m (not available in graphite) 180 lbs * D ft 220.2 ft-lbs + (a + b + c + d + ....) * 1.00 ft

1.6 m 180 lbs * D ft 246.0 ft-lbs + (a + b + c + d + ....) * 1.00 ft

1.96 m 180 lbs * D ft 271.8 ft-lbs + (a + b + c + d + ....) * 1.00 ft

M1 = Moment of rack with 180 lbs of force applied at D ft.
M2 = Moment of all fixed and trained personnel serviceable slide mounted products.

M2 moment calculations assume a 1.00 ft center of gravity for installed products.

If M1 is less than or equal to M2, no additional counter weight is needed.
If M1 is greater than M2, use the formulas below to determine the required counter weight.

Determine required counter weight if M1 is greater than M2:
Force (in lbs) = M1 - M2 ft-lbs/2.46 = amount of force required at 2.46 ft

X = Force lbs/30 lbs = number of C2790A 30 lbs ballast kits to install, where “X” is rounded up to the next
highest integer, e.g., 1.2 = 2 ballast kits.

CAUTION The anti-tip feet are not a substitute for ballast.

4Procedures

This chapter describes unpacking and repackaging your HP rack for shipment, and common procedures
such as positioning racks, installing accessories, and reversing the rear door.

Receiving

This section contains information pertaining to unpacking, inspection, and reshipment.
If the rack package is damaged upon receipt, request that the carrier’s agent be present when the protec-

tive covering is removed. Inspect the rack for damage (scratches, dents, bent pieces, etc.). If the rack is
damaged, notify the carrier and the nearest Hewlett-Packard Sales and Service office immediately.

CAUTION Do not lift an unpackaged rack with a fork lift

Unpacking, Handling and Moving

After unloading the rack at the shipping dock, check the order documents to the packing or shipping list to
see all parts arrived in good condition. Most likely you will move it on its pallet to its uncrating point.

Ensure clear passage from the receiving site to the uncrating site. The shipping dimensions and weights
are given below. Casters come attached, so the rack can be rolled when uncrated, to its next destination.
