General Safety Guidelines and Warnings

The following guidelines help ensure your safety and protect the device from damage. The list of guidelines might not address all potentially hazardous situations in your working environment, so be alert and exercise good judgment at all times.

  • Perform only the procedures explicitly described in the hardware documentation for this device. Make sure that only authorized service personnel perform other system services.

  • Keep the area around the device clear and free from dust before, during, and after installation.

  • Keep tools away from areas where people could trip over them while walking.

  • Do not wear loose clothing or jewelry, such as rings, bracelets, or chains, which could become caught in the device.

  • Wear safety glasses if you are working under any conditions that could be hazardous to your eyes

  • Never attempt to lift an object that is too heavy for one person to handle.
  • Never install electrical jacks in wet locations unless the jacks are specifically designed for wet environments.
  • Operate the device only when it is properly grounded.
  • Do not open or remove chassis covers or sheet-metal parts unless instructions are provided in the hardware documentation for this device. Such an action could cause severe electrical shock.
  • Do not push or force any objects through any opening in the chassis frame. Such an action could result in electrical shock or fire.
  • Avoid spilling liquid onto the chassis or onto any device component. Such an action could cause electrical shock or damage the device.
  • Avoid touching uninsulated electrical wires or terminals that have not been disconnected from their power source. Such an action could cause electrical shock.
  • Some parts of the chassis, including AC and DC power supply surfaces, power supply unit handles, SFB card handles, and fan tray handles might become hot. The following label provides the warning for hot surfaces on the chassis:

  • Always ensure that all modules, power supplies, and cover panels are fully inserted and the installation screws are fully tightened.

  • Single/two-hole system grounding is preferred for AC and DC. AC can also use the grounding pin in the power cord, and DC can use the PSU lug or the power cord ground if present.

  • Users should not attempt to make electrical ground connections by themselves but contact the appropriate inspection authority or electrician.

  • Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected. This precaution may be particularly important in rural areas.

  • Before removing or installing components in our device, connect an electrostatic discharge (ESD) grounding strap to an ESD point and wrap and fasten the other end of the strap around your bare wrist. Failure to use an ESD ground strap could result in damage to the device.

  • Install the device in accordance to the following local, national, and international electrical codes:

    • United States - National Fire Protection Association (NFPA 70) United States National Electrical Code.

    • Other countries - International Electromechanical Commission (IEC) 60364, Part 1 through Part 7.

    • Canada - Canadian Electrical Code, Part 1, CSA C22.1

  • Evaluated to the TN Power System

  • Suitable for installation in Information Technology Rooms in accordance to article 645 of the National Electrical Code and NFPA 75.

  • Locate the emergency power-off switch for the room in which you are working so that if an electrical accident occurs, you can quickly turn off the power.

  • Ensure that grounding surfaces are cleaned and brought to bright finish before grounding connections are made.

  • Do not work alone if potentially hazardous conditions exist anywhere in your workplace.

  • Never assume that power is disconnected from circuit. Always check the circuit before starting to work.

  • Carefully look for possible hazards in your work area, such as moist floors, ungrounded power extension cords, and missing safety grounds.

  • Operate the device within marked electrical ratings and product usage instructions

  • To ensure that the device and peripheral equipment function safely and correctly, use the cables and connectors specified for the attached peripheral equipment, and ensure they are in good condition.

  • Never install equipment that appears to be damaged.

  • Before working on equipment that is connected to power lines, remove jewellery, including rings, necklaces, and watches. Metal objects heat up when connected to power and ground and can cause serious burns or can be welded to the terminals.

  • AC-powered devices are shipped with a three-wire electrical cord with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this safety feature. Equipment grounding must comply with local and national electrical codes.

  • You must provide an external certified circuit breaker (2-pole or 4-pole circuit breaker based on your device) rated minimum 13 A/16 A/20 A in the building installation.

  • The power-cord serves as the main disconnecting device for the AC-powered device. The socket outlet must be near the AC-powered device and be easily accessible.

  • Before working on the device or near power supplies, unplug all the power cords from the device. All connections must be removed completely to remove power from the unit.
