Power Supplies; Power Supply Backup - Avaya IP Office Essential Edition PARTNER Version Reference Manual

Upgrading
Upgrading is performed using the Upgrade Wizard tool within the Essential Edition - PARTNER® Version
application (File | Advanced | Upgrade). It displays the systems it can detect, their existing software level and the
levels it has available.
· Check IP Office Technical Bulletins
Whenever upgrading check the latest IP Office Technical Bulletins for the various IP Office software releases involved
before proceeding. These may contain information relating to changes that occurred after this document was
completed. Bulletins are available from http://support.avaya.com.
· Multi-Stage Upgrades
The upgrade path may require several intermediate upgrades. Skipping an intermediate level may lead to incorrect
system operation and configuration corruption. Multi-stage upgrades are only necessary for control units. External
expansion modules can be upgraded directly between any two levels supported by the module.

2.13 Power Supplies

Each control unit and expansion module has an internal power supply unit that requires a switched power outlet socket
rated at 110-240V ac, 50-60Hz. Connection from that power outlet socket requires an appropriate locale specific power
cord which is not supplied with the unit and must be ordered separately.
External expansion modules are supplied with an external power supply unit (PSU). These external power supply units
include an integral 1.5 meter lead for connection to the control unit or expansion module. A power cord for connection
from the PSU to the power outlet is not included as this varies by locale. The appropriate power cord must be ordered
separately or sourced locally.
Power cords must not be attached to the building surface or run through walls, ceilings, floors and similar openings.
Installation measures must be taken to prevent physical damage to the power supply cord, including proper routing of
the power supply cord and provision of a socket outlet near the fixed equipment or positioning of the equipment near a
socket outlet.
For locales not detailed below an appropriate power cord must be obtained locally.

2.13.1 Power Supply Backup

The use of an Uninterrupted Power Supply (UPS) with any telephone system is recommended. Even at sites that rarely
lose electrical power, that power may occasionally have to be switched off for maintenance of other equipment. In
addition, most UPSs also provide an element of power conditioning, reducing spikes and surges.
The capacity of UPS systems and the total equipment load the UPS is expected to support are usually quoted in VA.
Where equipment load is quoted in Watts, multiply by 1.4 to get the VA load.
The calculation of how much UPS capacity is required depends on several choices.
