Glossary
This glossary provides entry-level explanations of common words and phrases used when mounting multiple
servers in racks. Detailed HP product information is available in numerous documents available from Hewlett-
Packard, such as technical data sheets and configuration guides. You can find them on our website at
http://www.hp.com/racksolutions/menu_lit.html.
1U – One EIA rack unit or 44.45 mm (1.75 inches) of vertical rack space. The
height of devices, when mounted in racks, are often expressed in multiples of
"units", for example, a 2U device requires two times 44.45 mm (1.75 inches) or a
total of 88.9 mm (3.5 inches) of vertical space in a rack. The actual device will in
reality be of slightly less height to eliminate mechanical interference with adjacent
devices.
Cable Management – Refers to a method of organizing and routing cables
(power and data) in the rear of the rack. Effective cable management means to
secure and bundle cables with the capability to efficiently route and channel the
cables in an organized fashion. HP offers a Rack Cable Management Kit (J1481A)
to provide a solution for the high-density rack environments associated with the
HP Netserver LP 2000r.
Console (sometimes referred to as a console system or KVM system) – Consists
of the video monitor, keyboard and mouse connected directly, or via a console
switch, to the rackmounted server for system administration purposes. Remote
management technologies enable the console and server to be physically separated.
Console Switch – A device that allows a user to operate multiple servers with
a single keyboard, monitor, and mouse.
KVM – Abbreviation for Keyboard/Video (Monitor)/Mouse as used in "KVM cable"
or "KVM switch." A console switch (above) is often referred to as a KVM switch.
PDU or Power Distribution Unit – Generally refers to a "power strip" with built-in
power protection and mounted within the rack to furnish AC power to a group of
rackmounted servers.
Rackmount Flat Panel Display – A system by which a flat panel monitor,
keyboard, and pointing device can be rack mounted to be used as system console
but only requiring 2U of “vertical rack space” instead of 13U as is common with
traditional monitor and keyboard combinations.

HP Netserver High Density Rack Solutions Overview (LP 2000r)
Retractable Keyboard Kit - A product, which allows for mounting a full-size
keyboard and mouse in a rack, occupying only 2U of vertical space and retracting
into the rack when not used.
Slides - A sliding rackmount solution comes standard with the HP Netserver LP
2000r. Slides enable in-rack serviceability of the server from the front of the rack.
Also included is a cable management arm, which allows the cabling to travel
effortlessly as the server extends from and retracts into the rack, similar to a
drawer in a filing cabinet.
UPS - Uninterruptible Power Supply. A device that provides battery power for a
server should the local AC power source fail. By providing this temporary power,
data corruption can be avoided when a power failure occurs.

Planning your racked system
After you've decided what computer and networking equipment and racks you need, you're faced with the
daunting task of physically locating the systems somewhere.
There are several conditions that must be met to assure that your system will work reliably and without
interruptions. First, you must plan for the physical space the equipment will occupy. Second, you must
ensure that the floor where the equipment will be located is strong enough to dependably support the
weight. Electronic equipment, although small in size, can be physically heavy—especially Uninterruptible
Power Supplies (UPS) that often use dense batteries.
Third, the system planner must calculate the power requirements and determine the number of Power
Distribution Units (PDU) and UPSs needed, as well as insuring that adequate circuitry is available in the
facility.
Lastly, you must insure that you can provide cooling for the equipment. Thermal requirements become a
concern when mounting a mass of electronic equipment in a small physical space and a conscientious plan-
ner will deal with thermal buildup in the preparation phase before the system is delivered and ready for
mounting in the rack.
Many of these calculations can easily be made with the special HP Netserver Rack Configuration
software available from HP for free at http://netserver.hp.com/netserver/tools/rack_asst.asp or by following
these basic steps:
1List all components.
2Configure those components into racks to determine the number and
size required.
Use the HP Netserver Configuration Guide, available at: http://http://netserver.hp.com/netserver/tools/, for
the height of the equipment. With this aid, calculate how many devices can be installed into any one rack
and its preliminary layout.
3Calculate the power requirements.
The electrical power required for a racked system must be calculated to:
1) Plan for an adequate facility supply for either 100-120V or 200-240V
2) Determine the number of Power Distribution Units needed
3) Determine the number of Uninterruptible Power Supplies required
Determine power requirements for the servers.
As mentioned above, the amount of servers that can be installed in one rack depends on a number of
parameters: Physical space in the rack, electrical (power) requirements and thermal limitations.
The worksheet at the end of this section allows you to calculate the actual power consumption for your
servers, including differences due to the number of processors, HDDs, and communication cards. Knowing
the actual power consumption lets you design a system, which precisely meets your current—and future—
requirements.
NOTE Always plan your infrastructure for appropriate expandability and future growth.

HP Netserver High Density Rack Solutions Overview (LP 2000r)
Calculate total input current requirements.
Input current requirements
Once you know the input power needed to operate the servers and other devices installed in the rack, you
can calculate the input current that is required for the rack by using this formula:
Input Power (W)
Input/Current (A) = AC Voltage (V)
Using this basic formula, you can evaluate whether your PDU, UPS and/or local AC power circuit can provide
the amount of current the equipment connected to it needs.
For example, if you are connecting four servers to a 16 A PDU, you can use the tables above and deter-
mine the total input power requirements for each server. In this example let’s assume we have calculated
these to be:
Server Total Input Power (W)
HP Netserver LP 2000r #1 176
HP Netserver LP 2000r #2 177
HP Netserver LP 2000r #3 180
HP Netserver LP 2000r #4 180
The total input power requirements for these four servers come to 713 W. By knowing that we are operat-
ing at a line power of 100 VAC and using the formula above we can calculate that the four servers will
require an input current of 7.13 A—well below the capacity of the 16 A rated PDU.
Circuit breakers
The HP Netserver LP 2000r power supply has been designed for low AC inrush current to reduce the pos-
sibility of tripping circuit breakers, typically located at a distribution panel.
Tripping of circuit breakers in the distribution panel may result from use of circuit breakers that are not
adequately rated for inrush current found in most electronic devices. Replacing the circuit breaker with a
suitable type is often the best solution.
The largest inrush current occurs when AC is first applied to the equipment in the rack. Often this inrush
current is independent of the “on” or “off” state of the individual devices. However, you can usually reduce
the total inrush current by applying power to the rack with the equipment in the “off” stage.
Power up sequence
Follow these instructions to minimize inrush currents and to minimize circuit breakers from tripping:
1. Power on peripherals one at a time; beginning with the tape back-up unit, followed by the mass-storage
units, keyboard, video monitor, and mouse switch, if any.
2. If your system includes an HP Console Switch, it must be powered on before the HP Netserver LP 2000r.
3. Last, power on each HP Netserver LP 2000r and wait for the fan in each server to spin up before power-
ing on the next one. If the HP Netserver LP 2000r doesn’t detect all the required components, it will not
complete the boot process and will report an error.
Power down sequence
There is no specific order to power down the equipment in a rack; however, there is an HP recommenda-
tion that it be done in the following sequence:
1. Ensure that the network users are properly warned of the power down.
2. Shut down the Network Operating System.
3. Power down the peripherals.
4. Power down the Netservers.

7
HP Netserver High Density Rack Solutions Overview (LP 2000r)
4Assess the thermal dissipation and ensure that there are adequate
cooling systems in place.
5Calculate the thermal conditions.
When mounting multiple servers in a rack you must also manage the thermal requirements. Although the
HP Netserver LP 2000r is specifically designed with excellent heat characteristics, you must know the
thermal load your particular rack configuration produces. This will allow you to manage the thermal envi-
ronment within the rack to provide the conditions required for optimum server operation.
The operating temperature specifications for the HP Netserver LP 2000r are:
5 to 35°C (41 to 95°F)1, 2
It is very easy to calculate the BTU/Hr an HP Netserver LP 2000r dissipates. Simply use the following
formula:
Input Power (watts) x 3.41=Thermal dissipation (BTU/hr)
If we use the example with the four servers above, we can easily calculate how many BTU/hr our servers
will produce:
713 W x 3.41 = 2,431 BTU/Hr
6Check your calculations.
As with any calculation or measurement, it is always valuable to check your numbers more than one time.
This is also the time to make adjustments to your layout. As you have gained insight into the power needs
and weight issues, you should adjust the placement of the equipment and add racks as needed. Plan for
easy access to equipment, which needs regular servicing, ensure that monitors and keyboards are easily
accessible to operators, and heavier items are placed low to provide stability for the system.
The special HP Netserver Rack Configuration software is available free of charge at:
http://netserver.hp.com/netserver/tools/rack_asst.asp.
1Subtract 1°C (2°F) to the maximum temperature for each 600 m (2000 ft) above sea level.
2Subtract 3°C (5°F) to the maximum temperature when it is mounted in a non-HP cabinet.

Power consumption worksheet - sample
The following worksheet makes it easy to make all the calculations you need to make.
Using the worksheet is simple. Inventory the HP Netservers LP 2000r that you will be rackmounting as to
the number of CPUs, memory boards, HDDs and add-in cards installed and input these numbers into the
“Number Installed” column. Multiply this number with the value in the “Unit Input Power (Watts)” column
to get the “Total Input Power (Watts)” for this particular server section. Finally, add all the values in the
“Total Input Power (Watts)” column to arrive at a total power consumption figure for the server.
Then using the formulas provided, calculate the current requirements and the BTUs/Hr.
For example: The calculations for an HP Netserver LP 2000r with 2 each 933 MHz processors, 2 GB of
memory, 2 each HDDs and a NetRAID 1M controller will show the following results:

Cable Management Accessory
The HP Netserver LP 2000r is delivered complete with slides ready for installation. However, if additional
cable management is needed, the HP Rack Cable Management Kit (J1481A) comes in handy.
It offers a solution to route and organize cables in high-density rack environments.
The kit contains four brackets for routing and channeling cables and 12 Velcro™ ties
for securing and bundling. The J1481A is designed to offer a flexible and scaleable
solution to accommodate various racking and cabling scenarios. Brackets can mount
on both the left and right rear columns and can be used with both rail and slide rack-
mounting. Multiple kits can be used in combination to provide additional cable man-
agement as the rack density increases. Each bracket is designed to contain approxi-
mately 30 large SCSI cables (1/2” diameter) or 120 LAN cables (1/4” diameter) or
any combination of the two (i.e. 15 SCSI/60 LAN).
The Rack Cable Management Kit offers complete compatibility with HP System/E
Racks and industry standard non-HP racks.

HP Power Distribution Options
HP offers a series of Power Distribution Units (PDU) for use when the HP Netserver LP 2000r is to be
mounted in a rack. The PDUs are especially convenient when mounting multiple servers as you simply
route each power cord to the closest PDU rather than to the local power source or the Uninterruptible
Power Supply (UPS), if used.
In addition to convenience, the HP PDUs also provide protection for the servers. All feature a circuit pro-
tector for each power phase. If one phase shorts, one or both of the circuit protectors trip.
Unlike other PDUs, the HP devices are slim and allow you to easily reach the servers and other equipment
from any angle. All mounting hardware is built in (mounting brackets) or included (mounting screws and
nuts) so there is nothing extra to order.
The PDUs mount quickly out-of-the-way on the rear posts of HP four-
post racks, either vertically along the posts or horizontally between
them, as your needs dictate. The rear columns have four dedicated
spaces to mount the PDUs, so that they won’t interfere with the
hinges and latches of the rack door or the equipment in the rack.
Routing power cords from the HP Netserver LP 2000r is straight for-
ward since the cords and the PDUs are all located at the rear of the
rack.
There are four types of PDUs available for use with the HP Netserver
LP 2000r, depending on your voltage and outlet requirements:

Because of the varying AC plug and receptacle requirements around the world, the PDUs do not come with
attached power cords. Separate cords must be ordered to fit your specific situation. These are the available
cords for each PDU:

HP recommends that you connect the power cord of the PDUs to an Uninterruptible Power Supply (UPS),
so be sure to read the chapter about UPSs and how to select the correct one for your application.
