The chassis in the Teradata platform system contain no user-serviceable components. Only a technically qualified customer service representative should service the system. The following cautions and warnings apply:
Proper Cooling and Airflow
Adequate ventilation must be maintained in the front and rear of the rack.
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. The customer must ensure that the receptacle is properly grounded.
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.
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.
Hazardous Electrical Conditions
Hazardous electrical conditions may be present on power, telephone, and communication cables. Power must be properly removed to access equipment. Contact Teradata Customer Support for assistance.
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).
Check nameplate ratings to assure there is no overloading of supply circuits that could have an effect on overcurrent protection and supply wiring.
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.
AC Input Rating Labels
- Cabinets with AC feeder boxes. 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.
- Cabinets with AC boxes (blue and orange). There are two AC boxes mounted in U spaces at the bottom of the cabinet. Each AC 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.)
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: 0617 represents June 2017.
