SAFETY WARNINGS
Before proceeding, carefully observe the following safety warnings:
Before installation, the entire manual must be read carefully. If you have any
questions, you should contact the authorized technical support.
Pay attention to the safety instructions during the installation, operation and
maintenance of this product. The installation, operation and maintenance
procedures should preferably be performed by qualified and trained personnel
authorized to carry out such tasks.
To prevent the risk of electric shocks, before connecting the equipment or
connecting cables, ensure the installation and operation of a grounding system.
Optical modules use invisible radiation laser transmitters. Although most
SFP/SFP+/QSFP+ on the market meet LASER safety specifications, never look
directly at the terminals of a module or an optical cord. Exposure to laser
emission may cause partial or total loss of vision.

short time, and then will turn off.
Table 5 - Status LED Behavior
SERIAL CONSOLE INTERFACE (RS-232)
The DM4170 switch has a console port for local management. The console port uses an RJ45
connector. A cable with a male RJ45 connector and a female DB9 connector must be used for
the connection to a computer or laptop.
The serial console cable is an accessory included in the DM4170. Additional cables can be
purchased separately via code 710.0137.xx or assembled as described in the following
images. The pin assignment of the RJ45 connector and its match with the DB9 connector is
described in TABLE 6-CONSOLE INTERFACE CONNECTOR PIN ASSIGNMENT.

USB INTERFACE CONSOLE
DM4170 products have a USB Console Interface (micro-USB connector) on the switch’s rear
panel for local management. The USB console port is accessible via Micro-USB cable (not
included). In Linux distributions USB port is automatically recognized by the hotplug system
and the console for management can be accessed directly from terminal. On Microsoft
Windows before Windows 10, a driver that emulates the USB port as a serial port will be
necessary, and then the console for management can be accessed by an emulation program.
In the Microsoft Windows 10 the USB port is recognized and emulated as a serial port, this
port can be accessed via a serial connection program.
DATACOM does not provide the driver that will emulate or create a virtual
serial port from the USB port. Due to security issues it is highly
recommended that only use driver from trusted sources.
USB HOST INTERFACE
The product provides a type A USB host interface on the rear panel that can operate
according to specification 2.0. There is no need to use this interface during the switch’s
installation process. Contact TECHNICAL SUPPORT for more information on using this
interface.
ETHERNET MANAGEMENT INTERFACE (MGMT)
The DM4170 has a Gigabit Ethernet interface used for local or remote management of the
switch. For details on how to use it, see the chapter, ACCESSING THE PRODUCT. This interface
has two status LEDs whose behavior is described in TABLE 7-MGMT INTERFACE LEDS.

ALARM INPUT AND OUTPUT
The DM4170 has two alarm inputs and one alarm output in an RJ45 connector. Alarm 1 and 2
inputs are isolated via optocoupler. External alarm detection occurs when the voltage
difference between IN+ and IN- reaches 12V. Table 10 presents the voltages and status for
alarm 1 and 2 inputs.

For alarm output, the equipment uses a relay. In an alarm situation

or when the switch is off,
pin 7 (common) is short circuited with pin 8 (NC). When operating without alarms, pin 7
(common) will be short circuited with pin 6 (NO), while pin 8 (NC) will be isolated.

PSUS AND POWER INPUTS
DM4170 switches have two PSU 125 power supply slots (supplied separately) on the front of
the switch.
The DM4170 switches have two PSU models: the PSU 125 DC that operates with DC -48/60
Vdc power supply and the PSU 125 AC that operates with 100/240Vac (50/60Hz) AC power
supply. For further details read the TECHNICAL SPECIFICATIONS chapter.
The PSU 125 DC has TERMINAL BLOCK power terminals; the terminals are located on the
front of the PSU.
The PSU 125 AC has three-pin IEC 320/C14 plugin power terminals; each terminal being
responsible for supplying power to each of the power sources.
The PSU 125 power sources operate in 1:1 redundancy, with only one of them being
sufficient to maintain the switch’s full operation. The combination of AC and DC power
sources on the same switch is permitted. The insertion/removal of the power cables and the
PSU 125 can be hot-swapped allowing the uninterrupted operation of the switch if one of the
two power sources is turned off or fails. The PSU 125 has a PWR LED on its front panel which,
when lit, indicates that it is properly powered and operational.

Figure 11 - PSU Panel 125 DC
Figure 12 - PSU Panel 125 AC
The equipment is de-energized through its power cable (s). The power outlet
must be nearby and easily accessible.
The electrical installation of the site should be protected by devices against short
circuits.
On the PSU 125 DC, fuses F1 and F2 support currents up to 15A. They are 86V
Fast Acting. If necessary, only replace it with one of the same specifications. The
F3 output fuse supports currents up to 15A. It is also 86V Fast Acting. If
necessary, also replace it with another one with the same specifications.
In the PSU 125 AC, fuse F1 supports currents of up to 5A. They are of Fast Acting
type, 250V. If necessary, only replace it with one of the same specifications. The
F1000 output fuse supports up to 15A. It is a Fast Acting type, 86V. If necessary,
also replace it with another one with the same specifications.
In the situation where both PSUs are present and the power inputs are energized
and operating with voltages within the specified range, the main power input
(MAIN) will take precedence over the BACKUP power supply.

3.10.2 Power Cables
3.10.2.1 PSU 125 AC
The PSU 125 AC includes a 3-meter power cord in the standard female IEC 320/C14 for the
NBR 14136 plug.
3.10.2.2 PSU 125 DC
The PSU 125 includes a 3.5 meter DC power cable in the PP 1 mm2gauge standard with both
ends open and the TERMINAL BLOCK standard male connector (normally shipped screwed to
the PSU 125 DC) for the installation of the cable.
Follow the information below to install the cable to the Terminal Block connector:
Step 1
•Remove the TERMINAL BLOCK connector from the PSU 125 DC by unscrewing
the two side screws of the connector using a 1/8" screwdriver (number 0) as
shown below:
Figure 15 –Removing the TERMINAL BLOCK from the PSU 125 DC
Step 2
•Locate the power cord shipped with the PSU 125 DC and cut it to the desired
preferred length. If the cable needs to be replaced, it is important that it have a
gauge of 1mm2or higher, and that the conductor colors follow the
