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: The slot on the far left (A) is exclusively reserved for the CPU module
included in the scope of supply. The slot on the far right (4) is reserved for the Net
module.

the component side pointing to the left.

(B) clicks into place.
