• Only authorized Siemens 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 HiPath Wireless Controller
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 HiPath Wireless Controller. 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.
