Power Supply requirements
IP Office Base Units and Expansion Modules should only be connected to a clean power
supply or a UPS.
Check the following:
– IP Office Base Unit and Expansion Modules :
IP Office modules require a separate switched mains supply. Power on the Expansion
Modules first. If the main IP Office Module does not detect an item at power on, it will
never use it. If power is switched on from a central point for all modules, then, as the
main unit is the slowest to start, this will be taken care of automatically.
– Standard Lump-in-Line Power Supply units are supplied with each IP Office/Expansion
Module. However, for IP400 Digital Station 30s that use more than ten 4424 terminals,
the 80W Lump-in-Line Power Supply must be used. This must be ordered separately
(see page 30). The power leads are country specific and must be ordered separately
(see page 30).
CAUTION: The Lump-in-Line PSUs supplied with each IP Office module must only be
connected to a 50/60Hz, 100-240V power source.
– UPS Equipment :
The use of UPS's to support the IP Office system during mains power failure is highly
recommended. Such equipment also provides mains conditioning. Contact Avaya for
details of preferred and tested suppliers and models.
