HPE Apollo 2000 System
Introduction
The HPE Apollo 2000 System consists of a chassis and nodes. There are three chassis options with different
storage configurations. To ensure proper thermal cooling, the four server tray slots on the chassis must be
populated with server nodes or node blanks.
Chassis
• HPE Apollo r2200 Chassis (12 low-profile LFF model)
• HPE Apollo r2600 Chassis (24 SFF model)
• HPE Apollo r2800 Chassis (24 SFF model with storage expander backplane)
Nodes
• HPE ProLiant XL170r Gen9 Server Node (1U)
• HPE ProLiant XL190r Gen9 Server Node (2U)
The chassis supports the combination of 1U and 2U nodes. One chassis can support a maximum of the
following:
• Four 1U nodes
• Two 1U nodes and one 2U node
• Two 2U nodes
For more information about product features, specifications, options, configurations, and compatibility, see the
product QuickSpecs on the Hewlett Packard Enterprise website .

Planning the installation
Safety and regulatory compliance
For important safety, environmental, and regulatory information, see Safety and Compliance Information for
Server, Storage, Power, Networking, and Rack Products, available at the Hewlett Packard Enterprise website
(http://www.hpe.com/support/Safety-Compliance-EnterpriseProducts).
Product QuickSpecs
For more information about product features, specifications, options, configurations, and compatibility, see the
product QuickSpecs on the Hewlett Packard Enterprise website.
Determine power and cooling configurations
Validate power and cooling requirements based on location and installed components.
Power requirements
Installation of this equipment must comply with local and regional electrical regulations governing the
installation of IT equipment by licensed electricians. This equipment is designed to operate in installations
covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of
Electronic Computer/Data Processing Equipment). For electrical power ratings on options, refer to the user
documentation supplied with that option.
WARNING:
To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply
branch circuit that provides power to the rack. Consult the electrical authority having jurisdiction over
wiring and installation requirements of your facility.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating UPS. This
device protects the hardware from damage caused by power surges and voltage spikes and keeps the
server in operation during a power failure.
HPE Apollo Platform Manager
HPE Apollo Platform Manager, formerly named HPE Advanced Power Manager, is a point of contact for
system administration.
To install, configure, and access HPE APM, see the HPE Apollo Platform Manager User Guide on the Hewlett
Packard Enterprise website (http://www.hpe.com/support/APM_UG_en).
Hot-plug power supply calculations
For more information on the hot-plug power supply and calculators to determine server power consumption in
various system configurations, see the Hewlett Packard Enterprise Power Advisor website.
Planning the installation 9

Server warnings and cautions
WARNING:
The chassis is very heavy. To reduce the risk of personal injury or damage to the equipment:
• Observe local occupational health and safety requirements and guidelines for manual material
handling.
• Remove all installed components from the chassis before installing or moving the chassis.
• Use caution and get help to lift and stabilize the chassis during installation or removal, especially
when the chassis is not fastened to the rack.
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment, remove the power
cord to remove power from the server. The front panel Power On/Standby button does not completely
shut off system power. Portions of the power supply and some internal circuitry remain active until AC
power is removed.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating uninterruptible
power supply. This device protects the hardware from damage caused by power surges and voltage
spikes and keeps the system in operation during a power failure.
CAUTION:
Do not operate the server for long periods with the access panel open or removed. Operating the server
in this manner results in improper airflow and improper cooling that can lead to thermal damage.
CAUTION:
To ensure proper thermal cooling, the four server tray slots must be populated with server nodes or
node blanks.
Space and airflow requirements
To allow for servicing and adequate airflow, observe the following space and airflow requirements when
deciding where to install a rack:
• Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
• Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or
row of racks.
Hewlett Packard Enterprise node s draw in cool air through the front door and expel warm air through the rear
door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to
enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the
cabinet.
CAUTION:
To prevent improper cooling and damage to the equipment, do not block the ventilation openings.
10 Server warnings and cautions

When vertical space in the rack is not filled by a server or rack component, the gaps between the components
cause changes in airflow through the rack and across the servers. Cover all gaps with blanking panels to
maintain proper airflow.
CAUTION:
Always use blanking panels to fill empty vertical spaces in the rack. This arrangement ensures proper
airflow. Using a rack without blanking panels results in improper cooling that can lead to thermal
damage.
The 9000 and 10000 Series Racks provide proper server cooling from flow-through perforations in the front
and rear doors that provide 64 percent open area for ventilation.
CAUTION:
When using a Compaq branded 7000 series rack, install the high airflow rack door insert (PN 327281-
B21 for 42U rack, PN 157847-B21 for 22U rack) to provide proper front-to-back airflow and cooling.
CAUTION:
If a third-party rack is used, observe the following additional requirements to ensure adequate airflow
and to prevent damage to the equipment:
• Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow 5,350 sq
cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to
the required 64 percent open area for ventilation).
• Side—The clearance between the installed rack component and the side panels of the rack must be
a minimum of 7 cm (2.75 in).
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the rack in a well-ventilated,
climate-controlled environment.
The operating temperature inside the rack is always higher than the room temperature and is dependent on
the configuration of equipment in the rack. Check the TMRA for each piece of equipment before installation.
CAUTION:
To reduce the risk of damage to the equipment when installing third-party options:
• Do not permit optional equipment to impede airflow around the chassis or to increase the internal
rack temperature beyond the maximum allowable limits.
• Do not exceed the manufacturer’s TMRA.
Grounding requirements
• The building installation must provide a means of connection to protective earth.
• The equipment must be connected to that means of connection.
• A service person must check whether the socket-outlet from which the equipment is to be powered
provides a connection to the building protective earth. If the outlet does not provide a connection, the
service person must arrange for the installation of a protective earthing conductor from the separate
protective earthing terminal to the protective earth wire in the building.
Temperature requirements 11

Rack warnings
WARNING:
To reduce the risk of personal injury or damage to the equipment, be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING:
To reduce the risk of personal injury or equipment damage when unloading a rack:
• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can
weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and might become unstable
when being moved on its casters.
• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle the
rack from both sides.
WARNING:
To reduce the risk of personal injury or damage to the equipment, adequately stabilize the rack before
extending a component outside the rack. Extend only one component at a time. A rack may become
unstable if more than one component is extended.
WARNING:
When installing a server in a telco rack, be sure that the rack frame is adequately secured at the top and
bottom to the building structure.
