Safety Information

Dangers

  • Replace the power cable immediately if it shows any sign of damage.
  • Replace any damaged safety equipment (covers, labels and protective cables) immediately.
  • Use only original accessories or components approved for the system. Failure to observe these instructions may damage the equipment or even violate safety and EMC regulations.
  • Only authorized Extreme Networks service personnel are permitted to service the system.

Warnings

  • This device must not be connected to a LAN segment with outdoor wiring.
  • Ensure that all cables are run correctly to avoid strain.
  • Replace the power supply adapter immediately if it shows any sign of damage.
  • Disconnect all power before working near power supplies unless otherwise instructed by a maintenance procedure.
  • Exercise caution when servicing hot swappable components: power supplies or fans. Rotating fans can cause serious personal injury.
  • This unit may have more than one power supply cord. To avoid electrical shock, disconnect all power supply cords before servicing. In the case of unit failure of one of the power supply modules, the module can be replaced without interruption of power to the ExtremeWireless Appliance. However, this procedure must be carried out with caution. Wear gloves to avoid contact with the module, which will be extremely hot.
  • There is a risk of explosion if a lithium battery is not correctly replaced. The lithium battery must be replaced only by an identical battery or one recommended by the manufacturer.
  • Always dispose of lithium batteries properly.
  • Do not attempt to lift objects that you think are too heavy for you.

Cautions

  • Check the nominal voltage set for the equipment (operating instructions and type plate). High voltages capable of causing shock are used in this equipment. Exercise caution when measuring high voltages and when servicing cards, panels, and boards while the system is powered on.
  • Only use tools and equipment that are in perfect condition. Do not use equipment with visible damage.
  • To protect electrostatic sensitive devices (ESD), wear a wristband before carrying out any work on hardware.
  • Lay cables so as to prevent any risk of them being damaged or causing accidents, such as tripping.
