Sources of Information

For information about an 1151C1 or 1151C2 power supply or instructions
on how to install it, refer to this instruction booklet packed with the
product. Additional installation information may often be found in the user
or installation manual of the terminal or adjunct equipment used with the
power supply. As the 1151C1 and 1151C2 are third generation power
supplies, the original product manuals may describe use with the prior
generation 1151A1/A2 or 1151B1/B2 models. The models 1151C1 and
1151C2 are direct replacements for these legacy Avaya and Lucent
models and may be substituted for them. (Please note that although the
physical appearance of the power supplies have changed, the basic
functionality has remained the same.)

Power Supply Description

The 1151C1 power supply is a “desktop”, single output 48 volt dc, 20 watt
power supply. The power supply can operate over a wide range of AC
input voltage and frequency: 90 - 264 VAC, 47-63 Hz.
The 1151C2 power supply is a “desktop “, single output 48 volt dc, 20
watt power supply

with battery holdover

. The power supply can operate

over a wide range of AC input voltage and frequency: 90 - 264 VAC, 47
63 Hz. When AC power fails the battery (if fully charged) should provide
approximately 15 minutes of holdover at full load (20 watts) or about 8
hours at light load (2 watts). As many factors may impact battery
performance (such as level of charge, age of the battery, temperature,
etc.), actual performance will vary.

Note:

Failure to use and install as directed could result in injury. No other

use of the 1151C1/C2 Power supplies is recommended or warranted. At
the time of publication, every effort has been made to insure accuracy of
this manual. However, it is possible that 1) some omissions have
occurred, or 2) new products have since been introduced that use the
1151C1 or 1151C2 power supply. If you are unsure concerning the
suitability of models 1151C1 or 1151C2 for a particular application, check
your product documentation or contact your local Avaya representative
for assistance.

CAUTION:

The 1151C1 and 1151C2 Power Supplies can

only

be used with

telecommunications equipment, indoors, in a controlled environment.

Operation

The maximum loop range between the telephone and the power supply
is 14 feet.
This power supply is intended to replace the MSP-1, 329A, 353A,
1151A1/A2 and the 1151B1/B2 DC power supplies, the Definity Adjunct
Power Kit (consisting of the KS-22911-L1/2 Plug-In Power Supply,
D6AP-87 cord and 400B2 adapter), and the 2012D AC transformer.
The 1151C1 power unit has a green LED that shows the unit has power
on the PHONE jack, pins 7 & 8 when AC power is applied.
The 1151C2 power unit has two LED's: a green LED that shows the unit
has power on the PHONE jack, pins 7 & 8 when AC power is applied or
running on battery and a YELLOW LED that shows the unit is charging
the battery when illuminated. When blinking, the GREEN LED indicates
that the unit is running on battery power.

The 1151C2 incorporates a new integrated feature that allows one to
easily disable the output when the supply is disconnected from AC mains
power. This allows storage of the power supply without rapid discharging
of the internal sealed Lead-acid battery due to continued operation of the
internal battery-voltage to output-voltage converter (henceforth referred
to as the “boost converter”). After disconnecting the 1151C2 power
supply from the AC mains following 1) normal use, or 2) periodic
recharge maintenance of the internal battery, the user should do the
following:

•

Locate the disable-switch access hole on the base of the
1151C2 power supply. Insert a fine non-metallic object (such
as a wooden or plastic toothpick) into the access hole and
depress the recessed momentary contact switch. This
operation disables the internal boost converter. Once the
boost converter is disabled, all status LEDs will turn off (this
may take a few seconds as the stored charge in the output
filter capacitors is discharged). This operation should only be
done when the power supply is to be stored or is to go
through a period of non-use.

Note:

One should

not

press the disable button when the supply is in

active operation during a power failure. Once the boost converter disable
button is pressed, the supply will no longer function until AC mains power
is restored. When AC mains power is restored to the power supply,
normal operation will resume.

Maintenance

The Avaya models 1151C1/C2 power supplies contain no user
serviceable parts. To reduce the risk of electric shock, do not
disassemble the product.
To clean the 1151C1/C2 power supply, first unplug the AC power cord
from the wall receptacle (or other AC source) and disconnect all cords
from the Line and Phone RJ45 jacks. Do not use liquid cleaners or
aerosol cleaners. Use a damp cloth for cleaning.
Like all batteries, the internal Lead-acid battery of the 1151C2 power
supply will self-discharge over a period of inactivity and must be
periodically recharged to avoid damage. This is not a concern during
normal supply operation, as the power supply will automatically recharge
as needed. However, when stored and disconnected from the AC mains
for an extended period of time, the battery should be recharged every six
months to prolong battery life and avoid damage resulting from deep
discharge. This may be done by simply connecting the power supply to a
source of AC power and allowing the battery to charge for at least twelve
hours. When battery charging is complete, if the power supply is to be
placed back into storage or disconnected again from the AC mains, one
should immediately disable the battery boost converter as outlined in the
“Operation” section above.

Connecting the Power Supply

The power output is provided through a modular jack on the power
supply. These jacks are labeled as follows:

The supply output is essentially isolated from earth ground and
depending on the particular application, either output pin may be used to
establish a reference potential. However, it is common in
telecommunications applications to think of the supply output as nominal
-48Vdc (pin 7) relative to a 0Vdc reference on pin 8.
The output jack, labeled “IP/DCP PHONE” is an 8-pin female non-keyed
RJ45 jack that can accept D8W and RJ45 modular plug cables.
The input jack, labeled “LAN/DCP” is an 8-pin female non-keyed RJ45
jack that can accept RJ45 modular plug cables, such as Cat5 (LAN) or
Cat3 (DCP line) cables. A Cat5e cable fitted with RJ45 modular plugs is
provided with the supply and may often be used in place of a D8W type
cable if desired.
