IP Office 2.1 40DHB0002USCL Issue 10c (11th May 2004)
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 30 Expansion Modules, that use more than ten
4424 terminals, the 80W Lump-in-Line Power Supply must be used. This must be
ordered separately (see Power Supplies
).
• Power leads are country specific and must be ordered separately (see Power Supplies).
• CAUTION
The Lump-in-Line PSU's 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.
