Updating or Upgrading the PBX
Warning: Touching voltage-carrying conductors or telephone connections can
cause life-threatening electric shocks. The PBX contains hazardous voltages, even
outside of the power supply unit (for instance ringer voltages). Work on active,
contact-hazardous parts is only permitted after creating a voltage-free state. Working close
to active parts is only permitted if these parts are voltage-free or are protected against
direct contact .
• Pull out the PBX's power plug. Also disconnect the device from additional power sources
(e. g. UPS, if installed).
• Wait at least 3 minutes for the discharge of any capacitor in the device after
disconnecting it from the main power supply.
Caution: Electrostatic charges can destroy sensitive components.
• Discharge electrostatic charges from yourself before touching the circuit boards
with your hands or any tools. To do this, touch a preferably earthed metal object, such
as the PBX's earthing terminal or a computer case.
Important: Before you insert a COMpact 2BRI module, first make the necessary port
settings on the module (operating modes and terminators).
The slot on the far left (A) is exclusively reserved for the COMpact CPU module included
in the scope of supply. The slot on the far right (4) is reserved for future extensions.
