Chapter 1
Introduction
The HPE Apollo kl20 server is a 2U rackmount server (see below). It has two main
subsystems: the 2U server chassis and four nodes based on single-socket serverboards.
Figure 1-1 The HPE Apollo kl20Server
This chapter describes the server using the following topics:
•“Server Chassis Features”
•“Serverboard Features”
•“Additional Hardware Components”
•“Special System Notes”

10
Server Chassis Features
Table 1-1 describes the main features of the HPE Apollo kl20 server chassis. For a
comprehensive description of the server features, please see the QuickSpecs at:
www.hpe.com/servers/apollo-kl20
Table 1-1 Server Chassis Features
Feature Description
System power The chassis includes a high-efficiency 80-plus Platinum certified power
supply, rated at 2000 Watts plus one redundant backup power supply. In the
unlikely event your power supply fails, replacement is simple and can be
accomplished without tools.
SATA subsystem The chassis supports up to 12 hot-swappable 2.5-inch or 3.5-inch SATA
drives in trays (3 for each node). These drives are hot-swappable units and
are connected to a backplane that provides power and control.
Note: The operating system you use must have RAID support to enable the
hot-swap capability of the drives.
Front control panel The chassis includes four front control panels on the handles of the chassis.
Each control panel provides you with system monitoring and control for one
server node. LEDs indicate system power, HDD activity, network activity,
system overheat, and power supply failure. A main power button is also
included on each control panel.
I/O ports The chassis is a proprietary-form-factor chassis designed to be used in a 2U
rackmount configuration. The chassis provides two low-profile add-on card
slots, a COM port, a VGA port, two USB 2.0 ports, one IPMI Ethernet port,
and four G-bit Ethernet ports per node.
Cooling system The chassis has four system fans powered from either the backplane or the
serverboards. If not powered from the backplane, the chassis powers the four
fans from the four motherboards so that when one of the motherboard
drawers is removed, the other motherboards will continue running all fans.
Air shrouds The chassis includes four plastic air shrouds that direct the airflow where
cooling is needed on each serverboard. Always use the air shrouds included
with your chassis on each serverboard.
Mounting rails The chassis includes a set of quick-release rails and can be placed in a rack
for secure storage and use. To set up your rack, follow the step-by-step
instructions included in this manual.

Additional Hardware Components
In addition to the serverboards and chassis, the following hardware components have been
included with the server:
• Four 1U passive CPU heat sinks
• Four plastic air shrouds
• Four 80x80x38mm cooling fans
• Four SATA backplanes
• Twelve hot-swap 3.5” HDD trays
• Eight 21-centimeter SATA cables
• Four riser cards
• One rail set

16
Special System Notes
With four serverboards acting as four separate nodes all incorporated into a single chassis, the
HPE Apollo kl20 server is a unique server system. The following sub-sections describe some
special notes affecting these aspects of the configuration:
• Independent nodes
• System power
• SATA backplanes/drives
Independent Nodes
Each of the four serverboards act as a separate node in the system. As independent nodes, each
may be powered off and on without affecting the others. In addition, each node is a hot-swappable
unit that may be removed from the rear of the chassis. The nodes are connected to the server
backplane by means of an adapter card.
Note: A guide pin is located between the upper and lower nodes on the inner chassis wall. This
guide pin also acts as a stop when a node is fully installed. If too much force is used when inserting
a node, this pin may break off. When inserting a node, slowly slide the node in until you hear the
click of the locking tab seating itself.
System Power
Dual 2000-Watt power supplies are used to provide the power for all four serverboards. Each
serverboard, however, can be shut down independently of the other with the power button on its
own control panel.

17
SATA Backplane/Drives
As a system, the HPE Apollo kl20 server supports the use of twelve SATA drives. A single
SATA backplane works to apply system-based control for power and fan speed functions but, at
the same time, logically connects a set of three SATA drives to each serverboard. Consequently,
RAID setup is limited to a three-drive scheme—that is, RAID cannot be spread across all twelve
drives. See section “Installing and Removing Disk Drives” for the logical hard drive and node
configuration.

Chapter 2
System Safety
This chapter describes basic safety precautions.
Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and
the HPE Apollo kl20 system from damage, as follows:
• Be aware of the locations of the power on/off switch on the chassis as well as the room's
emergency power-off switch, disconnection switch or electrical outlet. If an electrical
accident occurs, you can then quickly remove power from the system.
• Do not work alone when working with high voltage components.
• Power should always be disconnected from the system when removing or installing main
system components, such as the serverboard, memory modules and disk drives. When
disconnecting power, you should first power down the operating system first and then
unplug the power cords. The unit has more than one power supply cord. Disconnect two
power supply cords before servicing to avoid electrical shock.
• When working around exposed electrical circuits, another person who is familiar with the
power-off controls should be nearby to switch off the power if necessary.
• Use only one hand when working with powered-on electrical equipment. This is to avoid
making a complete circuit, which will cause electrical shock. Use extreme caution when
using metal tools, which can easily damage any electrical components or circuit boards they
come into contact with.
• Do not use mats designed to decrease static electrical discharge as protection from electrical
shock. Instead, use rubber mats that have been specifically designed as electrical insulators.
• The power supply power cords must include a grounding plug and must be plugged into
grounded electrical outlets.

19
General Safety Precautions
Follow these rules to ensure general safety:
•Keep the area around the HPE Apollo kl20 system clean and free of clutter.
•The HPE Apollo kl20 system weighs approximately 88 lbs (40 kg.) when fully loaded.
When lifting the system, two people at either end should lift slowly with their feet spread
out to distribute the weight. Always keep your back straight and lift with your legs.
• Place the chassis top cover and any system components that have been removed away from
the system or on a table so that they won't accidentally be stepped on.
• While working on the system, do not wear loose clothing such as neckties and unbuttoned
shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling
fan.
• Remove any jewelry or metal objects from your body, which are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit
boards or areas where power is present.
• After accessing the inside of the system, close the system back up and secure it to the rack
unit with the retention screws after ensuring that all connections have been made.
Caution: The HPE Apollo kl20 system and any other rackmounted equipment is not to be used
as a shelf or workspace.

ESD Precautions
Caution: Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to neutralize this
difference. The discharge can damage electronic components and printed circuit boards.
The following measures are generally sufficient to neutralize this difference before contact is
made to protect your equipment from ESD:
• Use a grounded wrist strap designed to prevent static discharge.
• Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for
use.
• Touch a grounded metal object before removing the board from the antistatic bag.
• Do not let components or PCBs come into contact with your clothing, which may retain a
charge even if you are wearing a wrist strap.
!
• Handle a board by its edges only; do not touch its components, peripheral chips, memory
modules or contacts.
• When handling chips or modules, avoid touching their pins.
• Put the serverboard and peripherals back into their antistatic bags when not in use.
• For grounding purposes, make sure your computer chassis provides excellent conductivity
between the power supply, the case, the mounting fasteners and the serverboard.
Operating Precautions
The following are two noteworthy operating precautions:
• Ensure that the chassis cover is in place when the server is operating to ensure proper
cooling. Out-of-warranty damage to the system can occur if this practice is not strictly
followed.
• Please handle used batteries carefully. Do not damage the battery in any way. A damaged
battery may release hazardous materials into the environment. Do not discard a used battery
in the garbage or a public landfill. Please comply with the regulations set up by your local
hazardous waste management agency to dispose of your used battery properly.
