Hardware
The chassis in a Vantage system contain no user-serviceable components. Only a technically-qualified customer service representative should service the system.
Failure to observe these precautions can kill or injure personnel or damage the system.

The following cautions and warnings apply:

General Cabinet Servicing

  • Do not extend more than one chassis in a cabinet at a time.
  • Do not compromise the weight distribution in the cabinet when removing or installing chassis.
  • Some chassis can weigh 50 pounds or more. If you must remove a chassis from the rack, two or more people may be required

Proper Cooling and Airflow

Adequate ventilation must be maintained in the front and rear of the rack.

Hazardous Electrical Conditions

Hazardous electrical conditions may be present on chassis and on power, telephone, and communications cables. Take appropriate precautions.

Grounding

This equipment has high leakage current. Reliable earth grounding of this equipment must be maintained. Grounding is provided by the power plug. The ground wire in each power cord is connected to a ground terminal in the power plug. You must ensure that the receptacle is properly grounded.

AC Power

  • The power on/off switches on rack chassis do not completely remove AC power. After shutting down and turning off a subsystem, the AC power cords must be unplugged from the chassis.
  • Do not service a non-hot-pluggable component unless the power off procedure has been performed and the AC power cord has been unplugged from the chassis.
  • The cabinet contains more than one AC power cord. To remove all power from the cabinet, you must disconnect all AC power cords from the site power source. Install the power outlets so they are near the equipment and easily accessible.
  • Do not plug unauthorized equipment into the AC feeder box. The AC feeder box provides at least 200 volts which will damage 120 volt equipment.

AC Input Rating Labels

AC input rating labels indicate the supply voltage and maximum number of Amps. There are two or four AC feeder boxes per cabinet. AC feeder boxes are mounted inside the rack on the right and left sidewalls. Each AC feeder box has one label.

The AC input rating label is located next to the AC power cord that connects to site power. (The site power cord is the power cord that leaves the cabinet through the top or bottom openings in the cabinet.)

Input Supply

Check nameplate ratings to assure there is no overloading of supply circuits that could have an effect on overcurrent protection and supply wiring.

Cabinet Power

The PDUs, AC feeder boxes, or AC boxes in a cabinet are not intended to provide power to equipment that is not mounted in the cabinet. Plugging equipment not authorized for the cabinet into the PDU, AC feeder box, or AC box may result in an overvoltage condition or damage the external equipment.

The cabinet contains more than one AC power cord. To remove all power from the cabinet, you must disconnect all AC power cords from the site power source. Install the power outlets so they are near the equipment and easily accessible.

Electrostatic Discharge Protection

  • Not following electrostatic discharge (ESD) precautions can damage your system.
  • Failure to completely and correctly seat a component, board, or adapter can result in damage to these parts.
  • ESD can damage disk drives, boards, adapters, and other parts. However, the chassis can withstand normal levels of environmental ESD while you are hot-swapping components.
  • Perform all service procedures only at an ESD workstation.
  • Wear an anti-static wrist strap attached to an unpainted metal surface on the rack or chassis when handling parts.
  • Always handle boards and adapters carefully and only by their edges.
  • After removing a board or adapter from its protective wrapper or from a chassis, place it component-side up on a grounded, static-free surface, or on a conductive foam pad.
  • Do not use the board or adapter protective wrapper in place of a grounded, static-free surface or conductive foam pad.
  • When removing components to reach others, store them on a static-free surface until reinstalling them.
  • Do not slide a board or adapter over any surface.

Electromagnetic Fields and Electrical Noise

Isolate the server from strong electromagnetic fields and electrical noise produced by electrical devices (such as elevators, copy machines, air conditioners, large fans, large electric motors, radio and TV transmitters, and high frequency security devices).

Rack Stabilization

Side stabilizers on the bottom of a stand-alone cabinet must remain in place as installed.

Two or more cabinets must be bolted together to prevent tipping when a chassis is extended.

No more than one chassis should be extended at one time. Extension of more than one loaded module could cause the rack to tip or fall.

A top-heavy rack could tip or fall. Proper weight distribution must be maintained.

Product Labels


  • Weight and opening one chassis caution labels

    Do not extend more than one BAR Data Domain chassis at a time.


  • Warning label about using rails and shelf properly

    Do not use equipment mounted on slides or rails as a shelf or work space.


  • Caution label about pushing cabinet and flooring

    Only push cabinet from front. Only roll over solid floor tiles.

Power overload warning label
To avoid power overload in a cabinet, only approved Teradata cabinet builds are supported. The cabinet build illustrations designate locations where chassis are not allowed. Installing chassis in these locations may result in a power overload if power to one side of the cabinet is lost.

Cabinet Manufacturing Date

The manufacturing date (month and year) is located in the lower right corner of the regulatory nameplate label. To find the regulatory nameplate, open the rear door and look down at the floor of the cabinet frame to the rear of the cable access hole. The date is of the form MMYY where MM represents the month (1 to 12) and the YY represents the year. Example: 0519 represents May 2019.
