Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards
to persons or equipment. An admonishment identifies a possible hazard and then explains
what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use
of the triangular safety icon (seen below), and are listed in descending order of severity of
injury or damage and likelihood of occurrence.
Danger:
injury, death, or substantial property damage if the hazard is not avoided.
Warning:
personal injury, death, or substantial property damage if the hazard is not avoided.
Caution:
personal injury or property damage if the hazard is not avoided.

1. GENERAL
The DMPS-10CE Power Supply, as shown in Figure 1, is a rack mounted power supply
providing +5, +12, and –12 Volts dc. It is expandable (with the basic power supply and up to
three DMPS-10EXP/CE expansion modules) to a total of four dc power sources each
providing + 5, + 12 and –12 volts.
DMPS-10CE POWER SUPPLY
The power supply including the basic unit measures 3.5 19 11 inches (8.9 48.3 27.94
cm). Each DMPS-l0EXP/CE expansion module measures 3.5 3.9 9.22 inches (8.9 9.91
23.5 cm) and fits into the basic power supply.
The DMPS-10CE has EN 60950 classification for use in Europe.
2. DETAILED DESCRIPTION
2.1 DMPS-10CE Power Supply (Basic)
The DMPS-10CE power supply is designed for the ADC Telecommunications PatchSwitch
system but will work well with other applications. It will operate with any input voltage
between 190 and 240 volts ac and any frequency between 48 and 62 Hz. Manual adjustments
are not necessary. Only one ac input is necessary per shelf for up to four dc power sources (the
basic unit plus three expansion modules).
AC
DC OUT 1DC OUT 2DC OUT 3DC OUT 4
8257-A
Figure 1. DMPS-10CE Power Supply
Input ac power is supplied via a six-foot, three-conductor power cord equipped with a
standard three prong with ground plug on one end and a special IEC 3-pin connector on the
other. The special IEC 3-pin connector plugs into the back of the basic DMPS-l0CE power
supply. Fuses are installed at the factory as described in “Power-Up of the DMPS-l0CE Power
Supply” section, page 6 of this manual.
There are four LED indicator lights on the front of the unit to indicate whether the power
supply and expansion modules are operating. The right-most LED (marked “DC OUT 1”) is
for the basic unit. Each of the three others (marked DC OUT 2, 3 & 4) displays the condition
of the expansion modules.

3. DMPS-10EXP/CE EXPANSION MODULE
The DMPS-l0EXP/CE Expansion Module, as shown in Figure 2, is designed to be installed
into the DMPS-10CE Basic Power Supply as dc power requirements expand at an installation.
The expansion module receives ac power from the basic shelf and is a completely selfcontained power supply in all other respects.
Up to three expansion modules can be mounted into the DMPS-l0CE Power Supply shelf. The
shelf requires a single ac power source (190 to 240 Vac, 48 to 62 Hz) to deliver up to 4 dc
outputs (via 9-pin cable connectors), each output supplying +5 Vdc, +12 Vdc and –12 Vdc.
Any input voltage between 190 and 240 volts ac can be accommodated without adjustment to
the power supply.
Outputs available from each of the modules (basic plus expansion modules) are +5 Vdc at up
to 4.5 Amps, +12 Vdc at up to 1.0 Amp, and –12 Vdc at up to 0.5 Amp.
Regulation is maintained on the respective voltages, keeping them constant to the tolerances
shown for the given current ranges:
+5 Vdc ± 5.0% for 0 to 4.5 Amps
ADCP-50-404 • Issue 2 • November 1998
+12 Vdc ± 10% for 0 to 1.0 Amps
–12 Vdc ± 10% for 0 to 0.5 Amps

5. OUTPUT CABLE ASSIGNMENTS
Output from the DMPS-l0CE Power Supply is delivered via a 6 foot, 16 gauge cable,
terminated in a 9-pin connector. Pin assignments on the connector are as follows:
Pin 1 — +5 Volts Pin 6 — Earth Ground
Pin 2 — +5 Volts Pin 7 — Common Ground for +5 and ± 12 V
Pin 3 — +12 Volts Pin 8 — Common Ground for +5 and ± 12 V
Pin 4 — No Connection Pin 9 — –12 Volts
Pin 5 — No Connection
See Figure 3 for sketch of the 9-pin connector.

6. INSTALLATION
6.1 DMPS-10CE Power Supply Installation
Remove each item from its shipping container and inspect the units for signs of damage. If
there are any damaged or missing parts, immediately file a claim with the commercial
common carrier or its agent, and notify ADC Telecommunications, Inc.
Normally, the ADC DMPS-10CE Power Supply is shipped with the standard single power
unit installed. Additional DMPS-10EXP/CE expansion modules are shipped in separate
containers. Occasionally, a power supply may be shipped with expansion modules installed. In
either case, installation of the power supply involves positioning the unit in the desired rack
space, near an ac utility outlet, and securing it with the mounting hardware normally used on
the mounting rack.
The DMPS-10CE Power Supply requires air for convection cooling. Air holes in
Note:
the top cover and bottom cover allow air to flow through the power supply chassis. For
this reason, be sure to mount the DMPS-10CE Power Supply in such a fashion as to
leave at least half of the top and bottom surfaces open to air movement.

7. DMPS-10EXP/CE EXPANSION MODULE INSTALLATION
Remove the DMPS-10EXP/CE expansion module from its shipping container and inspect it
for signs of damage or missing parts. If there are any damaged or missing parts, immediately
file a claim with the common carrier or its agent, and notify ADC Telecommunications, Inc.
Notice the connector plug on the front of the expansion module and also notice the one extralong pin on the plug. This pin is for chassis ground, and is extra long to assure that the ground
connection is made first and broken last for your protection when installing or removing the unit.
Caution:
power is connected to the power supply shelf.
Proceed with the installation as follows:
(a)Set the ac switch at the front of the power supply to off (down position), and unplug the

step (e) below.
(c)Notice the crimped sheet metal slots to the left hand side on the base of the power supply
shelf. The left-hand side of the “U” shaped base of the expansion module must slide into
these slots.
(d)Holding the expansion module with the “U” shaped base down and the 5-pin connector
plug forward, slide the module into the power supply, as shown in Figure 4, until the
connector pins engage the connector socket on the forward edge of the power supply.
Push in firmly to ensure proper connection of all pins in the plug.

Note:
expansion modules be connected to a load before ac power is applied.
8. POWER-UP OF THE DMPS-10CE POWER SUPPLY
The DMPS-10CE Power Supply has dual panel-mount fuse holders (located on the rear) to
provide over current protection in each leg of the ac input source. As shipped, the power
supply is fused with two 4-amp, time-delay fuses. To power the DMPS-10CE power supply
proceed as follows:
(a)Turn the power switch located on the front panel to the OFF (“0”) position.
(b)Connect the 220 Vac power cord provided to the power supply shelf.
(c)Cut the plug off the other end of the power cord. Replace the plug with a plug that
matches your utility outlet.
ADCP-50-404 • Issue 2 • November 1998
(d)Connect the other end of the power cord to the utility outlet.
(e)Set the ac switch at the front of the DMPS-10CE Power Supply to the on (“I”) position.
(f)Verify that power LED is lit on the front of the power supply for the basic power supply
and any expansion modules installed.
9. REPLACING THE LINE FUSE
The line fuses are located in dual panel-mount fuse holders on the back of the unit. To replace
a line fuse/fuses:
(a)Set the ac switch to OFF (“0”) position.
(b)Remove the line cord from its utility outlet.
(c)Disconnect the line cord from the socket in back of the DMPS-10CE Power Supply.
(d)Turn fuse holder carrier in a counter-clockwise direction and remove fuse carrier from
fuse holder. Fuse location is shown in Figure 5.
(e)Use an Ohm meter to check fuses for opens.
(f)Replace the bad fuse/fuses and reinsert the fuse carrier back into its socket. Turn fuse
carrier clockwise until fully seated.
(g)Repeat Steps d – f for the other fuse.
(h)Reconnect the power cord to the Power Supply and its utility outlet.
(i)Set the ac switch to ON (“I”) position.
