Requirements:
• A wide flat-bladed screwdriver

on the upper edge of the cover and pull
it upward.
The lock is released and the cover is
pulled slightly upward.

without resistance.
Updating or Upgrading the PBX
Warning: Touching voltage-carrying conductors or phone 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 module, first make the necessary port settings on the
module (operating modes and terminators).
Make sure that the module is fastened on the edge centred in relation to the connector.
