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).
Inserting a Module
1. Slide the module into the board guides with the
component side pointing to the left.
2. Press the module upward until the board lock
clicks into place.
