Rack Mount Warnings

The following installation guidelines are required by safety regulatory for maintaining
safety compliance when installing your system into a rack.

The equipment rack must be anchored to an unmovable support to prevent it from tip­ping when your system or piece of equipment is extended from it. The equipment rack
must be installed according to the rack manufacturer's instructions.

Install equipment in the rack from the bottom up, with the heaviest equipment at the bot­tom of the rack.

Extend only one piece of equipment from the rack at a time.

You are responsible for installing a main power disconnect for the entire rack unit. This
main disconnect must be readily accessible, and it must be labeled as controlling power to
the entire unit, not just to the system(s).

To avoid risk of potential electric shock, a proper safety ground must be implemented for
the rack and each piece of equipment installed in it.

Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the oper­ating ambient temperature of the rack environment may be greater than room ambient.
Therefore, consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (Tma) specified by the manufac­turer.

Reduced Air Flow - Installation of the equipment in a rack should be such that the amount
of air flow required for safe operation of the equipment is not compromised.

Mechanical Loading - Mounting of the equipment in the rack should be such that a haz­ardous condition is not achieved due to uneven mechanical loading.

Circuit Overloading - Consideration should be given to the connection of the equipment
to the supply circuit and the effect that overloading of the circuits might have on over-cur­rent protection and supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.

Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.

Particular attention should be given to supply connections other than direct connections
to the branch circuit (e.g. use of power strips).

PRECAUTIONARY MEASURES

XIV

Electrostatic Discharge (ESD)

Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only
by their edges without any component and pin touching. After removing a board from its
protective wrapper or from the system, place the board component side up on a
grounded, static free surface. Use a conductive foam pad if available but not the board
wrapper. Do not slide board over any surface.

Cooling and Airflow

Please be aware that slots and openings on the front and rear side of the chassis are
designed for ventilation; to make sure reliable operation of your system and to protect it
from overheating, these openings must not be covered or blocked. The openings should
never be covered or blocked by placing the product on a bed, sofa, rug, or other similar
surface. This product should never be placed near or over a radiator or heat register, or in a
built-in installation unless proper ventilation is provided.

Laser Peripherals or Devices

ified in this manual. Use of other products / components will void other safety regulatory
approvals of the product and will most likely result in non-compliance with product regu­lations in the region(s) in which the product is sold.

System power on/off: To remove power from system, you must remove the system from
rack. Make sure the system is removed from the rack before opening the chassis, adding,
or removing any non hot-plug components.

Hazardous conditions, devices and cables: Hazardous electrical conditions may be
present on power, telephone, and communication cables. Turn off the system and discon­nect the cables attached to the system before servicing. Otherwise, personal injury or
equipment damage can result.

Electrostatic discharge (ESD) and ESD protection: ESD can damage drives, boards, and
other parts. We recommend that you perform all procedures in this chapter only at an ESD
workstation. If one is not available, provide some ESD protection by wearing an antistatic
wrist strap attached to chassis ground (any unpainted metal surface on the server) when
handling parts.

ESD and handling boards: Always handle boards carefully. They can be extremely sensi­tive to electrostatic discharge (ESD). Hold boards only by their edges. After removing a
board from its protective wrapper or from the system, place the board component side up
on a grounded, static free surface. Use a conductive foam pad if available but not the
board wrapper. Do not slide board over any surface.

Installing or removing jumpers: A jumper is a small plastic encased conductor that slips
over two jumper pins. Some jumpers have a small tab on top that can be gripped with fin­gertips or with a pair of fine needle nosed pliers. If the jumpers do not have such a tab,
take care when using needle nosed pliers to remove or install a jumper; grip the narrow
sides of the jumper with the pliers, never the wide sides. Gripping the wide sides can dam­age the contacts inside the jumper, causing intermittent problems with the function con­trolled by that jumper. Take care to grip with, but not squeeze, the pliers or other tool used
to remove a jumper, or the pins on the board may bend or break.

INTRODUCTION ABOUT THE SYSTEM

1-1

1.1 Introduction

High Density 2U4N design for maximum performance

The Rackgo X F03A is designed for the highest compute density with four nodes in a 2 OU
space. Each node can install up to two SATADOMs for the operating system and up to four
extra hot-swappable SSD/HDDs for cache or data storage. Its RAID-ready configuration
preserves data integrity and avoids data corruption.

Vanity Free Design for better MTBF

By centralizing power supplies in the rack and removing unnecessary components from
the system, the F03A enhances system MTBF by 58% compared to other conventional
2U4N systems in the market. This will avoid system downtime caused by component fail­ure and minimize maintenance efforts.

VGA-redirection for on-site troubleshooting

F03A offers an optional dual-port 10Gbps SFP+ mezzanine card with an ASPEED 2300
chip, providing VGA-redirection for datacenters requiring on-site troubleshooting.
