Optiset E Local Power Supply
The Local Power Supply is required for the Analog Adapter. It
may also be required in other situations, depending on the
Optiset E telephone’s configuration, the type of phone cable
used, the length of the phone cable from the communications
server, and the type of communications server used. Only one
Optiset E Local Power Supply can be used at a time on an
Optiset E phone. However, one Local Power Supply can be
used on a primary phone and a second Local Power Supply can
be used on a secondary phone attached to the primary phone
through a Phone Adapter.
Installation of Local Power Supply
To install a local power supply:
1. Disconnect the phone line from the wall jack and from the
phone. New phones should have a line cord attached to the
phone, but may not be plugged into the wall jack. Plug the
line cord (PN 51A4871)
➀
that comes with the power supply
into the jack on the phone and into the jack on the power
supply labeled
.
2. Plug one end
➁
of the line cord that you disconnected from
the phone into the jack on the power supply labeled
.
3. Plug the other end
➂
of this cord into the wall jack. Note that
you could plug it into an Optiset E Phone Adapter installed
in another properly installed phone instead.
4. Plug the power supply

into a properly grounded 120 VAC
electrical outlet.
