zNineteen slots for Media Converter Modules.
zSupport for all Perle Media Converter Modules.
zMedia Converter Modules are individually secured and hot-
swappable for maximum connection reliability.
zDual AC/DC hot-swappable power supplies with load sharing
capabilities.
zPower Supply Module and Fan Status monitoring with built-in
Intelligent Alarm Relay technology.

Power Supply Module
The MCR9100 Chassis has two Bays for Power Supply Modules
located at the rear of the Chassis. The MCR1900 Chassis can support
two AC or two DC power supplies or a combination of either. Each
Power Supply Module has a cooling fan that draws air out of the
Chassis through front air vents on all face plates. The Perle
MCR1900 Chassis also comes with an Intelligent Alarm Relay
feature that will monitor the Chassis, Fans and Power Supply
Modules for error conditions. The Chassis and the Media Converter

9
Modules power requirements can be met with one Power Supply,
however a second Power Supply can be added for power redundancy
and load-sharing. If the Chassis has two Power Supply Modules, the
modules will use a load-sharing arrangement in which they both
supply power to the Media Converter Modules and Chassis. If either
Power Supply Module should fail, the other Power Supply Module
will assume responsibility for powering the entire Chassis, therefore
preventing any interruption of service. The backplane of the Chassis
will continue to power both fans even if a power supply is in a failed
state or the power switch is in the Off position. If either of the Power
Supply Modules fail, both alarm relays will be activated. Once the
alarm has been set, the backplane will continue to monitor the Power
Supply Module to see if the problem has been corrected and if so the
alarms will be reset.

be disengaged, therefore setting the alarm until the unit returns to a
normal state of operation.
A failure can be one of the following:
zLoss of power to the Power Supply Module(s).
zFan failure.
zOver temperature heat protection.
zOver voltage protection.
The relay is accessible via a set of three contact connections. These
contacts are known as "Normally Closed", “Common” and
"Normally Open", and are electrically isolated to the relay. The
contacts are rated for voltages up to 30 V DC/AC with a maximum
current of 3 A.
For terminals # 1 through 3, strip insulation from wire (7 mm - 8
mm) 9/32-5/16 using stranded wire size 18-12 AWG. Tighten screw
to a torque of 4.5 lb. per inch (0.51 Nm).
Terminal Description Usage
1 Normally
Closed
Use this with the Common terminal
to act as switch contacts that remain
closed when the unit is powered off
or in a failed state.
2 Common Use this terminal in conjunction with
the Normally Open or Normally
Closed terminals.
3 Normally
Open
Use this with the Common terminal
to act as switch contacts that remain
open when the unit is powered off or
in a failed state.

Power Requirements
AC Power Requirements
The MCR1900 chassis can be powered via an AC source. The
following are the ranges for the AC voltage supported by the unit.
Minimum: 85 VAC Nominal: 110/240 VAC Maximum: 265 VAC.
DC Power Requirements
The MCR1900 DC power supply has an integral Terminal
Connections block to facilitate connection to a DC source(s).
Electrical ground is directly connected by wire to the power supply’s
metal tray. The DC supply(s) should have adequate over-current
protection within the closed rack system and comply with local or
national standards applicable to the installation territory.
The following are the ranges for the DC voltage supported by the
unit;
Minimum: 24 VDC Nominal: 48 VDC Maximum: 60 VDC
You need wire gauge 14 to 18 AWG to connect the MCR1900
chassis to the power source.
WARNING
Before servicing this product ensure the power source has
been disconnected. For dual power supply models, ensure
both sources have been disconnected.
The MCR1900 with a DC power supply installed must be
installed in a restricted access location.

15
Grounding the MCR1900 Chassis
The MCR1900 should always be chassis grounded for safe and
proper operation.
Grounding the Chassis requires the following items:
zOne grounding lug (not provided).
zOne 12 AWG stranded or 14 AWG solid wire (not provided).
zCrimping tool (not provided).
zCross-head screwdriver (not provided).
The equipment must be grounded for safety and to ensure
ESD protection for correct operation and protection of the
internal circuitry.
WARNING
Before servicing this product ensure the power source has
been disconnected. For dual power supply models, ensure
both sources have been disconnected.
Note: For your safety, when installing this equipment, always
ensure that the Chassis Ground connection is installed first
and disconnected last.

Grounding
Screws
16
To attach the Chassis Ground, perform the following steps:
1. Using a crimping tool, attach the grounding lug to one end of a 12
AWG stranded wire or 14 AWG solid ground wire.
2. Remove the grounding screws located on the back middle of the
Chassis.
3. Attach the grounding lug to the Chassis and secure with the
grounding screws.
Installing the Media Converter Modules
To install or remove a Perle Media Converter Module refer to
Installing or Replacing Media Converter Modules on page 20 in
this guide.
Connecting the Alarm Relays (optional)
The MCR1900 provides a method of allowing you to connect an
external powered device such as a siren or light in order to inform
you should a power loss or failure occur. The Common relay
connection is used in conjunction with the Normally Closed or
Normally Open terminals. The Common terminal in conjunction with
the Open or Closed terminal acts as a switch contact that remains
open or closed when the Chassis is in a loss of power state.

17
Powering On an AC Powered Chassis
To power on an AC powered Chassis, perform the following
procedure.
1. Using the Perle supplied power cord, plug the power cord into the
AC power connector at the rear of the Chassis (repeat this
procedure if you have a second power supply installed in the
Chassis).
2. Plug the other end of the power cord to an appropriate power
outlet (repeat this procedure if you have a second power supply
installed in the Chassis).
3. Turn the power switch(s) to the On position.
4. A solid green LED indicates the chassis is powered up.
Powering On an DC Powered Chassis
To power on an DC powered Chassis, perform the following
procedure.
1. Locate the Barrier strip connector on the back of the DC power
supply module. Remove the covering plastic shield to expose the
three screw terminals ( + - Gnd)
2. On each end wire, remove the insulation from the copper wire 5
mm (3/16 of an inch).
3. First connect the electrical ground wire by loosening the right
screw terminal (Gnd) and wrap the end wire tightly around the
screw. Tighten the screw securely.
4. Loosen the left screw terminal (positive +) and wrap the end wire
tightly around the screw. Tighten the screw securely.
5. Loosen the middle screw terminal (negative -) and wrap the end
wire tightly around the screw. Tighten the screw securely.
6. Repeat this procedure if you have a second DC power supply.
7. Apply power at source.
8. A solid green LED indicates the chassis is powered up.
Note: Ensure power is NOT applied to the wires prior to
connection.

Installing or Replacing Media Converter Modules
The Perle Media Converter Modules may be installed in any order and
in any available installation slot. All Perle Media Converter Modules are
hot-swappable and can be removed or installed while the Chassis is
powered on.
Removing Media Converter Modules
1. Loosen the captive retainer screw on the front of the Media
Converter Module and gently pull the module towards you.
2. If not inserting a replacement Media Converter Module then cover
the opening slot with a face plate and secure the screw.
Installing or Replacing Media Converter Modules
1. If installing or replacing your Media Converter Module, remove the
Media Converter Module from its packaging.
2. Using a cross-head screwdriver, remove the screw holding the face
plate to reveal the slot opening.
3. Set the Modules DIP switches to the desired operating mode (refer to
the Installation Guide that came with the Media Converter Module).
4. Locate the top and bottom alignment guides inside the Media
Converter Module slot.
5. Using the module alignment guides gently slide the module into the
slot until it becomes flush with the front of the Chassis. Light
pressure may be needed to seat the module. Do not force the module
Warning Observe electrostatic discharge precautions when
installing the Media Converter Module(s) into the
Chassis. Failure to observe this precaution could
result in damage to the Media Converter Module.
