Disconnect the device from any external power line before opening of the housing.
In any case, the device is to be opened by trained service staff, only.
Environmental Conditions
The equipment is designed for indoor use and for an ambient temperature range of
-10…+50°C (14…122 °F) at 100 % load. The maximum operational altitude is
3000 m (3280 yds.) above sea level.
Mechanical Integration
It is not permitted to fix the chassis on the rack mount flanges, only.
Balanced weight distribution of the chassis has to be ensured by placing it on a solid
surface or by using rack rails.
Sufficient airflow through the DEV 5072 must be ensured to achieve best cooling
results. Do not block or obstruct the airflow through the chassis at the front and at
the rear side, e.g. by placing large components close to the front side.
It is recommended to provide 1 RU space in the rack above and below the chassis
to ensure a good air circulation.
Heat Hazard
Top, bottom, and side surfaces may become hot when operating the unit
continuously. To reduce the risk of injury from a hot surface, allow the surface
(particularly of a power supply module) to cool before touching.
Grounding, AC Connection, Cables
To minimize shock hazard the chassis must be connected to an electrical ground via
a ground wire, please refer to chapter 4.2.2. For the AC power connection, the
device must be connected to the AC power supply mains through a power cable
with three conductors per each installed power supply module and with the ground
wire firmly connected to an electrical ground (safety ground) at the power outlet.

User Manual DEV 5072
Any interruption of the protective ground conductor will cause a potential shock
hazard that might cause personal injury.
Risk of electrical shock and energy hazard:
Disconnecting one power supply line disconnects only one power supply module.
To isolate the DEV 5072 completely, disconnect all power supply lines!
Do not connect the DEV 5072 to mains supply exceeding the specifications for input
voltage (100…240 V AC ±10 %) and frequency (50…60 Hz).
The recommended AC cables to be applied are standard high temperature power
cables with type IEC 60320-C19 appliance plug appropriately rated to the
conditions of the country where the DEV 5072 is operated (e.g. European Union:
16 A/250 V; USA/Canada: 20 A/250 V).
For the characteristics of the DC output connections to be applied refer to the
related notes of chapter 4.2.2.
Live Circuits
Operating staff must not remove the cover of the DEV 5072 chassis or the cover of
power supply modules!
No component replacement is allowed for service staff that is not trained by
DEV Systemtechnik. To avoid injuries trained service staff has always to disconnect
all power connections, to discharge circuits, and to remove external voltage
sources before touching or replacing components.
Energy Hazard
The output terminals of the DEV 5072 chassis and the connector at the rear side of
power supply modules are capable of providing hazardous energy.
Due to the hazardous energy level, the output terminals and the power supply
module connectors therefore must not be accessible to operating staff.
For trained service staff protection has to be provided against inadvertent contact
with the output terminals of the DEV 5072 chassis.
Overcurrent Protection
A readily accessible branch circuit over current protective device (rated 30 A max.)
per each power supply line must be incorporated in the building wiring.
Each protective device must disconnect both poles of the power supply line
simultaneously.
Fuse
The internal fuse of a power supply module is sized for fault protection. If a fuse
was opened this indicates that service is required. Fuse replacement is to be
performed by trained service staff, only. The rating of the internal power supply
module fuse is F25 A H 250 V AC.

3 Product Description
DEV Systemtechnik has developed with the DEV 5072 a compact 1 RU chassis that
can be populated with one to four power supply modules. Each of the power
supply modules is capable to deliver up to 2500 W. Thus, the product provides up
to 10000 W at the two sets of robust galvanically isolated DC output terminals if
equipped with four power supply modules.
3.1 Features and Options
3.1.1 Communication Features
In addition to the LEDs at the power supply modules (please refer to chapter 3.1.2)
and to the "Status" LED at the rear side of the chassis (chapter 5.3), the DEV 5072
provides a Web Interface and SNMP support for the control and for the surveillance
of the product:
The Web Interface (chapter 5.4) is intended to serve as the local user interface for
operating the DEV 5072. It provides features for checking the health status and for
changing the setup and specific parameters of the device.
The implementation of SNMP (Simple Network Management Protocol) via the
Ethernet interface permits remote monitoring and control of the device
(chapter 5.5).
Finally, the device provides an FTP/FTPS-server for downloading log files and for
uploading firmware updates (chapter 5.6).
3.1.2 Power Supply Modules
As stated above, the DEV 5072 chassis can be equipped with up to four power
supply modules to deliver the required power. It is recommended to install an
additional power supply module for the pursued power in order to provide
redundancy if one of the power supply modules fails.
The three available types of power supply modules are to be ordered separately.
The types are different with respect to their DC output voltage: 12 V, 24 V, or 48 V.
Please refer to chapter 9 for the (spare) part numbers.
The LEDs at each power supply module are signalizing the operating status:
The "AC" LED signalizes that the power supply module is supplied with primary
power which is within specifications (green) or not (red).
The "DC" LED signalizes that the output voltage delivered by the power supply
module is within specifications (green) or not (red). Additionally, the LED is red
if the power supply module is deactivated via Web Interface (chapter 5.4.4.1)
or via SNMP (chapter 5.5.4.3.5.2); if the applied power supply module is not
approved by DEV Systemtechnik; and if the power supply module type does not
match the output voltage configuration of the DEV 5072 chassis (please refer to
the note below).

The extraction handle surrounding the module front in combination with the
module lock on the lower left side permits the convenient exchange of a module
(chapter 4.2.3). Power supply modules can be removed, installed, and/or
exchanged even during the operation of the device.
Note:
The DEV 5072 chassis is to be populated with one to four power supply
modules providing the same DC output voltage.
The installation of power supply modules usually starts in slot 1 (most left slot
at the front side of the chassis); unused slots are covered with a blind plate if
less than four power supply modules are installed.
The output voltage configuration of the DEV 5072 chassis is determined by the
power supply module located (and successfully detected) in slot 1 during the
latest power-up. The output voltage of all other installed power supply
modules has to match the output voltage of this power supply module.
I.e. it has to be made sure that all power supply modules in all slots of the DEV
5072 chassis are of the same type.
Please consider that if slot 1 is not populated during power-up, the output
voltage configuration of the DEV 5072 chassis remains unchanged.
AC plugs at the rear side of the chassis are not to be connected if the
corresponding power supply module slot is not populated!
If one of the power supply modules is deactivated via Web Interface
(chapter 5.4.4.1) or via SNMP (chapter 5.5.4.3.5.2), the "DC" LED of this power
supply module is red indicating that it is not delivering output voltage.
If all power supply modules are deactivated via Web Interface or via SNMP (i.e.
no power supply module delivers output voltage, but the AC connections are
established), the "AC" LED of all installed power supply modules is on.
The following table informs about the maximum ratings for each type of power
supply module, chapter 4.2.2 states the ratings of the chassis. Note that the
maximum output current is reduced by 5 % if more than one power supply
module is installed in the chassis.
3.1.3 Other Options
Eight Web Interface licenses are included in the delivery of the DEV 5072; additional licenses for the Web Interface can be ordered initially via Option 79. It is
possible to purchase additional license keys at any time, please contact
DEV Systemtechnik.

1 * User manual (this document)
4.2 Installation of the Product
4.2.1 Mechanical Assembly of the Product
Please refer to the warnings in chapter 2.3 regarding the mechanical integration of
the DEV 5072. For the assembly in a 19" rack the rack slots must be prepared with
rails for the chassis. After inserting the chassis in the rack, fix the chassis with four
screws to the rack at its rack mount flanges.
For the assembly in combination with the DEV 5101 Online UPS for DEV 5072,
please refer to the DEV 5101 user manual.
4.2.2 Grounding, Data Cables, and Power Connection
For the warnings for the DEV 5072 with respect to "Grounding, AC Connection,
Cables" please refer to chapter 2.3.
First, the DEV 5072 chassis needs to be connected to the rack via a ground wire.
The grounding bolt (labeled GND in the figure above) is located on the right at the
rear side of the chassis between the AC plugs for the second (AC2) and for the first
(AC1) power supply module slot. To connect a cable, please take off the upper nut
and the first washer of the grounding bolt. Then connect the grounding cable which
must have a ring tongue terminal matching the M4 fastening bolt. The washer and
the nut have to be tightened again.
Next, establish the external Ethernet connection by plugging the appropriate
Ethernet cable from your network to the Ethernet port of the device (Eth); the
configuration of the Ethernet interface is described in chapter 4.4.2.
In combination with the DEV 5101, the serial interface of the DEV 5072 is to be
connected to the Battery Management Controller (BMC) chassis as stated in the
DEV 5101 user manual. For standalone applications of the DEV 5072 and if the basic

network setup via serial interface is required (chapter 4.4.2.2), a serial connection
between a PC and the serial connector (Com) of the DEV 5072 is to be established
using a 1:1 cable; the configuration is described in chapter 4.4.1.
Please refer to the corresponding chapters for the functionality of the push button
(Reset, chapter 4.2.4) and of the LED (Status, chapter 5.3).
Before connecting AC power cables the DC output connections (to be realized
either as cables or as solid connection bars) are to be installed. Due to the high
output current of the DEV 5072 chassis, both sets of the DC output terminals
(+A/-A, +B/-B) are to be used for the DC wiring. Note that the maximum rating per
set of the DC output terminals is 380 A and that it is highly recommended that the
output load is distributed evenly among both DC output terminal sets!
The prepared DC output connections are to be attached using the provided
M6 nuts. It has to be ensured that the M6 nuts at the power supply chassis for
securing the DC output connections are tightened with a torque of 4.1…7.3 Nm
(36.3…64.6 lbf-in).
Note:
In combination with the DEV 5101, the instructions for the DC wiring are
different; please refer to the DEV 5101 user manual.
If using cables for the DC output connections, the number and the diameters of
the cables depend on the current to be supplied and on the length of the
cables. Make sure that an appropriate configuration with respect to number
and to diameter of the cables is installed.
For the cable cross section per polarity and per set of output terminals with an
assumed total maximum output current of 200 A, a minimum of 35 mm² cable
cross section is according to regulations.
The next table informs regarding the total maximum output current of the
chassis (i.e. assumed input voltage >170 V AC) with respect to the installed type
and number of power supply modules:
For the connection of cables to the M6 threaded studs of the DC output
The DEV 5072 can be used to supply a positive DC voltage by connecting the

terminals double-hole lugs with 15 mm (~5/8") center distance and 90° cable
taps capable of at least AWG 2 (i.e. ~35 mm²) wires are recommended, e.g.
Burndy YA2CL2TC1490. As an alternative, a number of ring tongue terminals
with an inner diameter of 6 mm (0.24") and with a maximum outer diameter of
14 mm (0.55") can be used.
DC output connections in the fashion that the positive connections are running
to the positive DC output terminals (+A, +B). The negative DC output
connections are to be attached to the negative DC output terminals (-A, -B).
To obtain a negative DC voltage the polarity of the DC output connections has
to be reversed, i.e. the negative DC output connections are to be attached to
the positive DC output terminals (+A, +B) and the positive DC output
connections are running to the negative DC output terminals (-A, -B).

The grounding bolt is independent of the potential of the output terminals and
is connected to PE (Protective Earth) potential of the AC plugs as well as to the
ground (GND) potential of the data interface connectors.
Next, after the application of the DC output wiring, connect appropriate AC power
cables (chapter 2.3) to the AC plugs (AC1…AC4, IEC 60320-C20). Depending on the
number and on the location of the installed power supply modules, only the
corresponding AC power cables are to be connected.
Finally, make sure that all installed power supply modules of the DEV 5072 are
powered up sequentially (to minimize the switch-on surge) without the connected
load being turned on! If the power supply modules are powered up sequentially
with the connected load turned on, there is the risk of overloading already
activated power supply modules before the necessary number of activated power
supply modules is delivering the required power.
Note:
Due to the high power consumption of each power supply module, it is highly
recommended to use separately fused phases of the available AC mains.
The installation location of the power supply modules can be selected freely,
though it is recommended to install the power supply modules in the slot order
(as shown in the front view figure of chapter 3.2).
Make sure that the corresponding AC power cables are connected.
4.2.3 Installation and Exchange of Power Supply Modules
The DEV 5072 is delivered with the number of ordered power supply modules that
are already installed. Therefore, you may proceed in reading the next chapter.
In case that a power supply module has to be exchanged or that a DEV 5072 is to
be upgraded with an additional power supply module, the following instructions
are to be noticed. Please consider the related warnings stated in chapter 2.3.
Though the power supply modules are hot pluggable, it is recommended for
exchange operations either to power down the DEV 5072 or at least to deactivate
the corresponding power supply module via Web Interface (chapter 5.4.4.1) or via
SNMP (chapter 5.5.4.3.5.2).
To install an additional power supply module remove the blind plate covering the
desired slot in the first step.
To remove -for instance- the first power supply module from the chassis, elevate
the module lock (indicated by the vertical green arrow in the figure above) and pull
the extraction handle (horizontal red arrows in the figure above) simultaneously.
Please check type and output voltage of the spare (or additional) power supply
module before the installation, since it has to be made sure that all power supply
modules in all slots are of the same type (please refer to the note in chapter 3.1.2
regarding the output voltage configuration of the DEV 5072 chassis).
Install the (replacement) power supply module by gently pushing it into the chassis
with the extraction handle closed. Lift the module lock during the last section of the
insertion process and make sure that the module is inserted deep enough (the
Copyright DEV Systemtechnik GmbH 2016-2017 13
Page 14
User Manual DEV 5072
front of the module has to level with the chassis frame) and that the lock becomes
engaged when releasing it.
Next -and if applicable-, the DEV 5072 can be powered up.
If the DEV 5072 was powered up during a power supply module exchange, the new
power supply module is activated automatically (if type and output voltage are
correct). If there were changes on the default configuration (chapter 4.3.1) of the
corresponding module, the current settings are transferred to the new module.
This can be verified easily by checking the settings via the Web Interface.
If the DEV 5072 is upgraded with an additional power supply module, the
surveillance of the power supply is to be enabled via the Web Interface
(chapter 5.4.4.1) or via SNMP (chapter 5.5.4.3.5.11).
4.2.4 Reset of the Device and the Restore of Factory Defaults
During power-up or after a reset of the device, the controller of the DEV 5072
performs a health check and scans the assemblies of the device e.g. to detect,
whether a module is installed in a slot or not. If there is a module installed, the
settings for this slot are transferred to the module.
A reset of the DEV 5072 is necessary only if there were applied elementary
changes, e.g. restoring the factory defaults via Web Interface.
The reset of the device can be performed in three different ways:
1. Reset via the "Reset" push button located at the rear side of the chassis
(please refer to the drawing in chapter 4.2.2): Press and hold (e.g. by using a
ballpoint pen) the "Reset" button for approximately 3 seconds.
2. Reset via the serial interface when terminating the configuration program
(chapter 4.4.2.2.1).
3. Reset via Web Interface (chapter 5.4.6.4.2).
Note:
During a reset, the device still delivers output voltage, i.e. the power supply
module outputs are not deactivated while resetting the device.
If a power supply module was deactivated via Web Interface (chapter 5.4.4.1)
or via SNMP (chapter 5.5.4.3.5.2), it will be activated after a power cycle or
after a reset!
It takes about 60 seconds after a reset or after a power cycle that the device is
completely accessible again via the serial interface, via Web Interface, and via
SNMP.
If –for any reason– a restore of the factory defaults is required, please proceed
as described in the following:
Usually, the factory settings (chapter 4.3) can be restored via Web Interface (chapter 5.4.6.4.1). If –for any reason– the device is not accessible via Web Interface, the
factory settings can be restored in the following manner:
Press and hold the "Reset" push button located at the rear side of the chassis
(e.g. by using a ballpoint pen).
After ~20…50 seconds the yellow LED on the "Ethernet" connector starts to blink
(8 times, for ~4 seconds). If the "Reset" push button is released during this
blinking, the factory settings are restored and a device reset is initiated.

User Manual DEV 5072
4.3 Device Factory Settings
The DEV 5072 is delivered with factory settings as described in the following.
It is possible to restore these settings, please refer to chapter 4.2.4.
4.3.1 Factory Settings for the DEV 5072 Chassis
The factory settings for the DEV 5072 are dependent on the configured power
supply module type:
1. DEV 5072 configured for 12 V Power Supply Modules
Voltage Setpoint / Current Alarm Level: 12.0 V / 684.0 A
2. DEV 5072 configured for 24 V Power Supply Modules
Voltage Setpoint / Current Alarm Level: 24.0 V / 355.6 A
3. DEV 5072 configured for 48 V Power Supply Modules
Voltage Setpoint / Current Alarm Level: 48.0 V / 177.8 A
In combination with the DEV 5101, the output voltage it is determined by the
battery voltage and cannot be adjusted!
Otherwise, the output voltage setpoint for the DEV 5072 chassis can be adjusted in
a range as described in chapter 3.1.2 via Web Interface (please refer to chapter
5.4.4) and via SNMP (chapter 5.5.4.3.6).
The current alarm level for the DEV 5072 chassis can be changed via Web Interface
(chapter 5.4.4) and via SNMP (chapter 5.5.4.3.7). If the total current of the chassis
exceeds the current alarm level, this is just used for warning notice purposes and
does not physically limit the output current.
The other limitations for the power supply modules which need to be considered
depend on the AC input voltage: As shown in in chapter 3.1.2 a power supply
module delivers up to 1500 W power if supplied with 100…170 V AC and is capable
to deliver more power if the AC input voltage is larger than 170 V AC (but smaller
than 265 V AC).
Note –if not in combination with the DEV 5101– that it is possible to alter the
relation of the output voltage setpoint and of the current alarm level to values that
may exceed the capabilities of the DEV 5072 chassis and of the power supply
modules. Since the firmware does not restrict the input set values according to the
present operating environments, please consider the conditions regarding AC input
voltage, DC output voltage, and the number of installed power supplies. The table
below may assist for altering the factory settings for the current alarm level of the
device (via Web Interface and/or via SNMP).
Note:
For input voltages >170 V AC and if the output voltage is adjusted to values
below the nominal voltage of the applied power supply modules, the maximum
feasible current of the power supply modules (as stated in chapter 3.1.2)
becomes the limiting factor; i.e. the resulting output power is lower as for
higher output voltages. E.g. if a chassis equipped with a single 12 V power
supply module and if the output voltage is adjusted to the lower limit, this
results in 9.6 V * 200 A = 1920 W for the applied power supply module instead
of the 2400 W power for output voltages ≥ 12 V.
After the exchange of a power supply module, the replacement power supply
module inherits the settings of the corresponding slot.

The current measurement accuracy of the power supply modules is 10 %. I.e.
do not be alarmed if a power supply modules displays a current of e.g. 10 A
without a load attached.
The following table provides an overview on the maximum possible output
current for the DEV 5072 considering the AC input voltage range, the output
voltage setpoint, and the type and number of installed power supply modules.
It may be useful for adjusting the current alarm level of the device (via Web
Interface and/or via SNMP). Please note that the default value for the current
alarm level is defined as ~90 % of the absolute maximum possible output
current.
For changing the network setup, please refer to chapters 4.4.2.2 & 5.4.6.2.1.
4.3.3 Factory SNMP Settings
The factory SNMP settings are configured as follows:
Read Community: public
Write Community: private
Local/Remote changeable via SNMP:
Additionally, the default community for all four Trap Destination IP Addresses is set
to public and all configurable traps are disabled. If an address is defined without the
explicit port assignment, the standard SNMP trap port 162 is assigned implicitly.
For changing the SNMP setup, please refer to chapter 5.4.6.2.2.
16 Copyright DEV Systemtechnik GmbH 2016-2017
Page 17
User Manual DEV 5072
There are software factory settings for some SNMP objects, please refer to the
corresponding chapters:
Two hardware interfaces are provided for the communication with the device:
a serial interface and an Ethernet interface.
In combination with the DEV 5101, the serial interface of the DEV 5072 is used for
the communication with the battery management controller chassis as stated in
the DEV 5101 user manual. For standalone applications of the DEV 5072, the serial
interface can be used for the basic network setup. The Ethernet interface of the
DEV 5072 is used for the operation of the device via Web Interface or via SNMP,
and for the access via the integrated FTP/FTPS-server (chapter 5.6).
4.4.1 Serial Interface
The Sub-D 9 pos female connector for the standard serial RS 232 interface is
located in the middle at the rear side of the DEV 5072 chassis; chapter 7 describes
the pin assignment.
The serial interface configuration for DEV 5072 standalone applications is described
by the following parameters:
In combination with the DEV 5101, the serial interface configuration of the
DEV 5072 is different; please refer to the DEV 5101 user manual.
4.4.2 Ethernet Interface
The RJ-45 connector for the 100Base-TX Ethernet interface is located at the rear
side of the DEV 5072; for the pin assignment please refer to chapter 7.
4.4.2.1 Ethernet Connection
If the device is to be connected to a PC only, the connection can be established via
a direct Ethernet cable (or through a local hub/switch) between the Ethernet
connector of the device and the Ethernet connector of the PC. The network setup
of the PC is to be altered that it is in the same subnet as the device. If it is intended
to use the factory network settings, the IP address of the standalone PC is to be set
to 192.168.0.x, with x in the range 1…254, except 11, which is the default address of the
device, e.g. set the IP address of the standalone PC to the default gateway address
192.168.0.99.

User Manual DEV 5072
If the device is to be connected to the local network, make sure to change the
network setup as required. Ask your network administrator for the details on
network parameters which are to be used.
The factory network settings are subject of chapter 4.3.2.
There are implemented two different methods to change the network setup; either
via Web Interface (please refer to chapter 5.4.6.2.1) or via the serial interface as
described in the following chapter.
4.4.2.2 Network Setup via the Serial Interface
Note that in combination with the DEV 5101 the connection for the network setup
via the serial interface is realized differently; please refer to the DEV 5101 user
manual.
To change a few elementary parameters of the network setup via the serial
interface for a standalone DEV 5072, establish a hardware connection between a
RS 232 port of a PC (e.g. COM1) and the DEV 5072 serial interface using a straight
cable; please refer to chapter 7 for the pin assignment of the serial connector.
Next, start a terminal application (e.g. MS Windows HyperTerminal) on your PC.
Note:
The interface settings of the terminal application have to match the serial
interface configuration (chapter 4.4.1); otherwise, it is not possible to enter the
configuration program as described below.
The terminal application is to be configured that the "Backspace" or "←" key on
the keyboard works properly in the application, and that it sends a <CR> only
(and not a <CR><LF>) when hitting the "Enter" or the "" key on the keyboard.
If using MS Windows HyperTerminal, select the "Properties" entry from the
"File" menu and click on the "Settings" tab. There select "ANSI" from the
"Emulation:" drop down list and then click on the button to
uncheck "Send line ends with line feeds" as shown in the following figure:

Page 19
User Manual DEV 5072
4.4.2.2.1 Start and Termination of the Configuration Program
In this application the serial interface is exclusively used for the configuration program, i.e. if the terminal application is started (and connected) either the following
text is displayed initially or after hitting the "Enter" or "" key on the keyboard:
DEV login:
With the following authentication the configuration program is started:
DEV login: config<CR>
Password: devConfig<CR>
Note:
<CR> stands for hitting the "Enter" or "" key on the keyboard.
All characters/commands to be entered are case sensitive.
After successful authentication, the configuration program is launched. After start
and after the finalization of most of the choices the program lists the choices that
can be performed:
config
======
1 set IP address (192.168.0.225)
2 set netmask (255.255.0.0)
3 set gateway (192.168.0.99)
q quit without saving
x save configuration and exit
your choice >
Choices can be executed by typing the character in the first column of each line
followed by a <CR>. The second column of each line provides a short description of
the choice and the third column displays in parentheses the current setting of the
corresponding choice. In the example above, the IP address and the netmask are
different from the factory network settings (please refer to chapter 4.3.2).
When using the "q" choice the configuration program terminates and the login
message is displayed again:
DEV login:
When using the "x" choice the configuration program saves all changes made and
resets the device (i.e. rebooting the device):
your choice > x<CR>
rebooting the device, please wait...
Again, during a reset the device still delivers output voltage, i.e. the power supply
module outputs are not deactivated while resetting the device.
After a device reset it takes a few moments before the serial interface is accessible
again as described at the beginning of this chapter.
In the following, the available choices are explained:

5 Operation of the Product
After going through the installation steps as described above, the device is ready to
use. The possibilities for monitoring and control are subject of chapter 3.1.1.
Before the operation via each of these possibilities is explained, the different device
operation modes are described:
5.1 Modes of Operation
Local Mode and Remote Mode define the manner how the device is controlled. The
operation mode can be changed via Web Interface (please refer to chapter 5.4.2)
and via SNMP (chapter 5.5.4.3.1).
Note that the factory setting for the operation mode is Remote Mode.
5.1.1 Local Mode
The Local Mode is implemented for the operation via Web Interface.
The SNMP remote interface is disabled for modifying the settings, but enabled for
status queries.
5.1.2 Remote Mode
The Remote Mode is implemented for the operation via SNMP.
In Remote Mode, the status of the power supplies is indicated via the LEDs at the
device and via Web Interface, but the control functionality of the Web Interface is
disabled.
5.2 Initialization of the Device
The device performs a health check and a configuration check during power-up and
after a device reset. This takes about 60 seconds; there is no manual configuration
necessary, all settings (including the operation mode) after power-up or after a
reset remain unchanged.
Note:
During a reset, the device still delivers output voltage, i.e. the power supply
module outputs are not deactivated while resetting the device.
If power supply modules are deactivated via Web Interface (please refer to
chapter 5.4.4.1) or via SNMP (chapter 5.5.4.3.5.2), they will be activated after a
power cycle or after a device reset.
5.3 Operation at the Device
Except the "Reset" push button (please refer to chapter 4.2.4), there are no
elements to be operated. The status of the power supply modules is indicated via
LEDs, which were presented in chapter 3.1.2.
The "Status" LED (the location at the rear side of the chassis is shown in
chapter 4.2.2) is off during power-up and turns to green after the successful
activation of the DC outputs of the power supply module(s). The "Status" LED is red if
(at least) one module is not approved by DEV Systemtechnik, and/or if the output
voltage of (at least) one module does not match the output voltage configuration
of the DEV 5072 chassis (chapter 3.1.2).

User Manual DEV 5072
5.4 Operation via Web Interface
The Web Interface is a comfortable user interface for operating the product, i.e. the
device is controlled via a computer and a web browser as the communication
application. Several users (assumed the appropriate number of licenses) can access
the device at a time. Eight licenses are included in the delivery and it is possible to
purchase additional license keys at any time, please contact DEV Systemtechnik.
Note:
Most of the screenshots shown in this section were made from the Web Inter-
face of a DEV 5072 equipped with two 48 V power supply modules. Other
configurations deviate from the layout but not from the basic functionality.
For power systems in combination with the DEV 5101, the Web Interface of the
DEV 5072 provides additional functionality, which is indicated in the following
description.
The screenshots shown here vary with respect to date and time; they were
updated for relevant changes only, otherwise they are the same as the
screenshots of the latest versions of this document.
5.4.1 Start of the Web Interface
To start the Web Interface open a web browser (recommended is Mozilla Firefox
(version 3.5 or higher) but also Chrome, Opera, Safari, or Internet Explorer (starting
with version 8, recommended is version 9 or higher) are supported) and type in the
URL (IP address) of the device:
http://<IP-of-the-device>/
After a moment, the Start Screen of the Web Interface appears (as shown above).
22 Copyright DEV Systemtechnik GmbH 2016-2017
Page 23
User Manual DEV 5072
To log on the first time use the factory default account:
Username: ADMIN
Password: ADMIN
After entering username and password, click on .
Note:
Both, username and password are case sensitive!
Note the header in the Start Screen:
The "48 V" appended to "DEV 5072" indicates that the chassis is configured for
48 V operation (please refer to chapter 3.1.2).
The labels "SystemName" and "SystemLocation" are the SNMP variables
"System Name" and "System Location"; both can be set within the SNMP setup
(chapter 5.4.6.2.2).
If the Start Screen is not accessible, make sure that the computer accessing the
device is in the same subnet of the common network (chapter 4.4.2.1).
If the network connection to the device gets lost during a session, an appropri-
ate notification will pop up. After confirmation, the web browser is redirected
to the Start Screen. If the device is accessible again, a new authentication is
required.
During power-up or a device reset the device displays a different screen:
DEV 5072 48 V
SystemName
SystemLocation
If the device is operational (again), the screen usually automatically changes to
the Start Screen, thus enables the input fields to be edited; if not, please use
the refresh functionality of your web browser (e.g. the function key F5).
The Web Interface permits the definition of a number of users for accessing the
Web Interface in parallel (in accordance to the number of installed licenses). An
additional user who tries to log in receives a corresponding notification
informing about the logged in user(s), e.g.:
Copyright DEV Systemtechnik GmbH 2016-2017 23
Page 24
User Manual DEV 5072
It is recommended to change the password of the factory default ADMIN
account (chapter 5.4.6.1.2).
The language of the screenshots shown here is English, as a second language
currently German is available (chapter 5.4.6.1.2).
5.4.2 The Main Window and Common Features of the Main Tabs
After successful authentication the main window of the Web Interface shows up
with the Status Tab opened, which is the default view:
In the top of the window on the left side, the five tabs are located ("Status",
"Control", "Events", "Setup", and "Info"). The active tab is highlighted; clicking on
an inactive tab opens the corresponding tab instead.
In the middle on the top of the window two buttons are located indicating that the
device is either in Remote Mode (as shown in the screenshot above) or in
Local Mode (as shown in the screenshot of chapter 5.4.3).
Changing the operation mode of the device via Web Interface is performed by
clicking on the desired button, e.g. clicking in the situation above on the
button highlights the button instead of the button.
Right to these buttons the currently logged in user (here: "ADMIN") and the permission of the user (here: "admin") are shown. Please refer to chapter 5.4.6.1.3 for
more information on this subject.
Then, the date and time of the device are displayed right to this information. The
correct date and time depend on the proper configuration of an NTP timeserver
and of the timezone (chapter 5.4.6.2.1). Note that if there was no timeserver
24 Copyright DEV Systemtechnik GmbH 2016-2017
Page 25
User Manual DEV 5072
detected at power-up, the device sets the date and time to "01-Jan-2000 00:00".
In the right corner close to the company logo, the button is located. Clicking
on this button returns the Web Interface to the Start Screen.
Note:
It is recommended to finish a Web Interface session by clicking on the
button. This instantaneously releases the allocated license and enables other
users to log in.
A timeout feature (20 seconds) is implemented within the Web Interface, i.e. a
session is automatically terminated (and the allocated license is released) if a
user who is currently logged in closes the web browser.
This means that a Web Interface session is kept open unless the button
is operated or if the web browser (in other words, the connection to the
device) is closed.
It is possible to start a Web Interface session on another computer using the
same user account; this automatically terminates the session on the preceding
computer.
5.4.3 Status Tab
The upper part of the Status Tab shows the front side of the DEV 5072 in a simplified representation. Thus, a quick overview is provided regarding the detected configuration and the health status of the device.
In the lower part of the Status Tab, the Active Events Window is located. This window shows appearing and pending errors with the corresponding error message
and a date/time stamp. The error shown in the next screenshot was triggered for
demonstration purpose by unplugging the AC connector of the second power
supply module. To obtain more details on the errors open the Events Tab (please
refer to chapter 5.4.5).
Copyright DEV Systemtechnik GmbH 2016-2017 25
Page 26
User Manual DEV 5072
Note:
The illustration of the front side of the DEV 5072 is very symbolic: The
representation of each power supply module just shows three indicators for
"AC OK", "DC OK", and for "Fan OK" which are either red or green.
To suppress error messages of uninstalled power supply modules it is re-
commended to disable the surveillance of the related modules (chapter
5.4.4.1). As shown in the screenshot the representation of a disabled module
appears in gray, is additionally labeled with "No Surveillance", and the related
error messages are no longer displayed in the Active Events Window.
5.4.3.1 Status Tab with UPS
If the UPS functionality is activated (please refer to chapter 5.4.6.3.1), the Status
Tab of the DEV 5072 Web Interface provides an additional box below the symbolic
representation of the fourth power supply module.
In combination with the DEV 5101, this box is indicating the status of the UPS
functionality:
The displayed status is equivalent to the "System Status" shown in the structuring
entry "UPS" of the Control Tab (chapter 5.4.4.2). Other possible status messages are
shown in the following screenshot assembly:
26 Copyright DEV Systemtechnik GmbH 2016-2017
Page 27
User Manual DEV 5072
5.4.4 Control Tab
On the left side the Control Tab contains the two or three structuring entries
"Power Supply", "Power Modules", and "UPS" (if the UPS functionality is activated, please
refer to chapter 5.4.6.3.1) in order to branch to the different functionalities, i.e.:
for the display of the status and for the setup of the output voltage setpoint
and of the current alarm level within the "Power Supply" entry
or to the setup of the single power supply modules which are shown as sub-
entries within the "Power Supply" entry (chapter 5.4.4.1)
or to monitor the status of the power system in combination with the
DEV 5101 (chapter 5.4.4.2)
When opening the Control Tab for the first time in a Web Interface session, it
appears with the "Power Supply" entry activated which consists of two sections:
In the upper "Status" section, first the "Output Voltage" is shown indicating the
average of the output voltages of all installed power supply modules.
The second information is the "Total Current" which is the sum current
obtained at the output of each installed power supply module.
The "Setup" section permits the adjustment of "Voltage Setpoint" (i.e. the
output voltage of the device; chapter 3.1.2 provides information on the output
voltage ranges for the different power supply module types) and of "Current
Alarm Level" by entering appropriate values. The value for the "Current Alarm
Level" does not physically limit the output current but serves as a threshold for
alarming purposes. I.e. the measured current values of the installed power
supply modules are summed up and this sum is compared with the stored
alarm level. If the sum exceeds the level, an alarm is triggered. Chapter 4.3.1
states the default setting of the alarm level for each power supply module type
and the table at the end of chapter 4.3.1 informs regarding the adjustment of
the "Current Alarm Level" with respect to the present configuration. This
chassis is equipped with two 48 V power supply modules, thus it is appropriate
Copyright DEV Systemtechnik GmbH 2016-2017 27
Page 28
User Manual DEV 5072
to adjust the "Current Alarm Level" to ~90% of the maximum possible current
capability. Note that after settings have been altered within this section in
Local Mode (!), a click on the button is necessary to apply the
changes.
Note:
If the UPS functionality is activated (chapter 5.4.6.3.1), it is not possible to
adjust the "Voltage Setpoint" (as explained in chapter 4.3.1).
5.4.4.1 Power Supply Module
If on the left side of the Control Tab a power supply module is selected within the
structuring entry "Power Modules", the corresponding panel appears on the right side.
Within the "Status" section, some information on the selected power supply
module is shown: "Serial Number"; "Module Status" ("Enabled", "Disabled",
"Not present", "Wrong Voltage", or "Unsupported module type"); red, green, or
gray indicators for "AC Status", "DC Status", and "Fan Status"; and the display of
"Output Voltage", "Output Current", and "Temperature".
The "Surveillance Enable" check box is used e.g. to enable or to disable the
surveillance of a power supply module slot.
Clicking on the button turns off the output of the selected power supply
module, e.g. to enable a safe removal of the module; please refer to chapter 4.2.3.
Note that if a power supply module is deactivated (i.e. the "Module Status" is
"Disabled", the "DC Status" is red, but the "AC Status" and the "Fan Status" are
green), the button is labeled instead. The button is grayed out if the
device is in Remote Mode and/or if the "Module Status" of the related power
supply module is "Not present", "Wrong Voltage", or "Unsupported module type".
As stated in chapter 5.4.3 it is recommended to disable the surveillance of
unpopulated power supply module slots:

5.4.4.2 Control Tab with UPS
If the UPS functionality is activated (please refer to chapter 5.4.6.3.1) and if on the
left side of the Control Tab the structuring entry "UPS" is selected, the
corresponding panel appears on the right side.
The status shown in in the following screenshot is supposed to reflect the normal
condition of the properly configured and operating power system:
the power supply modules of the DEV 5072 are working normally, i.e. the
attached load is supplied by the power supply modules,
the latest battery test returned the status "Battery OK",
the output voltage ("V") equals the battery voltage ("VBat"), the batteries are
charged to a 100%, i.e. the voltage setpoint of the power supply modules is
adjusted to the battery voltage, and there is neither charging nor discharging,
and the communication with the Battery Management Controller (BMC) is
working properly, thus the "System Status" is "Ready".
Copyright DEV Systemtechnik GmbH 2016-2017 29
Page 30
User Manual DEV 5072
The following examples are intended to illustrate a few different states of the UPS
functionality:
Battery test:
To start the battery test click on the button in Local Mode (!),
alternatively the battery test can be triggered in Remote Mode via SNMP
(chapter 5.5.4.3.14). While the battery test is executed, the "System Status" is
indicated here as "Selftest active", alternatively the "System Status" can be
obtained via the Setup Tab (chapter 5.4.3.1) or via SNMP (chapter 5.5.4.3.9):
After completion of the battery test the result is shown in the line labeled
"Latest Selftest Result". Normally "Battery OK" is displayed as in the initial
screenshot. In certain situations (e.g. during discharge) the battery test cannot
be executed, thus the result is "Not executed":
Note that in rare cases the result of the battery test is returned as "Unknown"

User Manual DEV 5072
Discharging:
If the power supply modules of the DEV 5072 are not delivering power (e.g. due
to a total AC fail), this is indicated by the background of the square with the
AC/DC symbol in the upper left being red. The attached load is now supplied by
the batteries; the upward pointing current arrow indicates the discharging of
the batteries:
The available bridging time for a DEV 5072 power supply module fail depends
on the size of the load and on the capacity of the batteries. If the battery
voltage reaches a critical voltage the "System Status" changes from
"Discharging" to "Discharging (Prewarn)":
Copyright DEV Systemtechnik GmbH 2016-2017 31
Page 32
User Manual DEV 5072
Charging:
If the power supply modules of the DEV 5072 are working normally again, the
attached load is supplied by the power supply modules and the batteries are
charged, indicated by the downward pointing current arrow:
UPS Problems:
If the UPS functionality is activated (chapter 5.4.6.3.1) without installed
DEV 5101 or if there are problems with the communication to the BMC, no
sensible information is displayed in the panel. In these cases "System Status"
and "Latest Selftest Result" usually indicate "Unknown", numbers are represented either as "???" or as zero values, and instead of the battery capacity
indication with the percentage value a white bar labeled "Battery capacity
unknown" is shown:
Furthermore, the white bar labeled "Battery capacity unknown" is displayed if
the power system is put into operation initially or after a longer lasting power
down period, since the battery capacity indication is a longer lasting process
based on fully charged batteries.

5.4.5 Events Tab
With the activated entry "Error Log" (default) on the left side of the Events Tab, a
table of the errors is displayed on the right side as shown above.
The different errors are listed line-by-line, i.e. each error carries a Date/Time stamp
(in the format: "DDD DD MMM YYYY hh:mm:ss", here e.g. "Tue 07 Jun 2016 10:40:36") informing
about the last occurrence of that error. The second column is a Counter reporting
the number of occurrences of that error (here: "1"). The third column denotes
whether that error is Ack.nowledged ("X") or not ("") (here: "", i.e. <space>, meaning
not acknowledged). The fourth column shows whether that error is Pend.ing ("X")
or not ("") (here e.g. "X", i.e. pending). The fifth and the sixth columns inform about
the error code No. in Hexadecimal (here e.g. "1302") and in Decimal (here e.g. "4866")

Below, the buttons and are located:
An error can be acknowledged by highlighting (i.e. clicking on) the related line and
by operating the button afterwards. The intention of the
acknowledgement of an error is to provide means to mask out a pending error of
the Active Events Window in the Status Tab (chapter 5.4.3). If a confirmed error
occurs again, the counter in the table is increased and the acknowledgement is
reset (i.e. the "X" disappears & the Active Events Window reports the error again).
An acknowledged and not pending error can be deleted from the list by highlighting
the corresponding line, followed by clicking on the button.
If a deleted error occurs again, a line added at the beginning of the table.
Note:
It is possible to acknowledge and to delete more than one entry at a time by
highlighting more errors using the <Ctrl> or the <Shift> key of the keyboard in
combination with mouse click(s).

Users with "read" permission have no rights to acknowledge or to delete error
entries (chapter 5.4.6.1.3).
If an error is still pending or not acknowledged, it cannot be deleted.
If the entry "User Log" is selected on the left side of the Events Tab, a table
providing user activity data appears on the right side as shown in the next
screenshot.
The data is listed in the table line-by-line, i.e. each log entry carries a Date/Time
stamp (in the format: "DDD DD MMM YYYY hh:mm:ss", here e.g. "Tue 07 Jun 2016 10:33:54"). The
second column shows the User (here: "ADMIN"). The Log column reports the activity
(here e.g. "Logged in from 192.168.0.148").
The "User Log" panel comprises the button and the button:
With the button, the table is cleared (without confirmation!) and after
operating the button, a browser specific window pops up and suggests the
storage of the table as "userlog.csv". The file extension .csv (comma-separated values)
indicates the file format: The file contains a line per log entry; each of the three
columns of a log entry is delimited by a semicolon (";") character as the column
separator.
Note:
The Error Log and the User Log can be downloaded as text files via the
integrated FTP/FTPS-server (chapter 5.6).

5.4.6.1 User Setup
The menu item User Setup on the left side of the Setup Tab provides access to the
Password and Language entry for all users and access to the Authorization entry
and to the User Management entry for users with "admin" permission.
5.4.6.1.1 Authorization
The currently logged in user has to have "admin" permission to access the
Authorization entry.
The drop down list "Authorization Method" provides three entries defining the user
community that can access the device:
"Local": This is the standard authorization method. The user community is
defined and managed via the User Management entry (please refer
to chapter 5.4.6.1.3).
"RADIUS": The user community is defined and managed by one or two RADIUS
servers. The permission category can be altered individually via the
User Management entry (chapter 5.4.6.1.3).
"LDAP": The user community is defined and managed by an LDAP server.
The permission category can be altered individually via the User
Management entry (chapter 5.4.6.1.3).
If "RADIUS" is selected via the drop down list "Authorization Method", two
additional lines are displayed. Enter the IP address of the (one or two) RADIUS
36 Copyright DEV Systemtechnik GmbH 2016-2017

server(s) –the RADIUS port number 1812 is added automatically- and the
(corresponding) "Shared Secret".
A click on the button applies the changes made.
The LED symbol right to the address fields indicates whether the saved (!) entry is
an available network resource (green) or not (red).
If "LDAP" is selected via the drop down list "Authorization Method", a number of
entries are shown. First, enter the address of the "LDAP Server". After saving the
LED symbol right to the address field indicates whether the entry is an available
network resource (green) or not (red). Next, enter the "Port" number (default entry
is "389"), and possibly select "SSL/TLS" via the related drop down list:
If "LDAPS" (or "StartTLS") is selected, the "Port" number is adjusted automatically
to "636" (or "389") which can be altered before saving. The two methods do
require a valid certificate in .pem format. Thus, the "Upload Certificate" input field
permits the insertion of a filename including the path where the file resides.
Alternatively, the button can be used to locate the file. After the selection
of the file, click on the button to activate the file transfer to the device. The
successful upload of the certificate file is initiated indicated via a pop up window:
Copyright DEV Systemtechnik GmbH 2016-2017 37
Page 38
User Manual DEV 5072
A stored certificate can be deleted by operating the button plus the
confirmation via the appearing pop up window.
For the "Account" and "Password" entries a service LDAP user is to be entered who
has access to the directory structure of the LDAP server.
"Base DN" defines the distinguished name (DN) for accessing the naming structure
of the LDAP server, e.g. uid=user,ou=people,dc=example,dc=com and "Login Attribute" may be
used to add the LDAP login attribute, e.g. sAMAccountName.
Finally, a click on the button applies the changes made.
Note:
If the active authorization method is "RADIUS" (or "LDAP"), all approved users
of the RADIUS (or of the LDAP) server may access the device using their RADIUS
(or their LDAP) authentication.
Passwords (except the password of the ADMIN user) cannot be changed locally
if the active authorization method is "RADIUS" (or "LDAP").
The first login of a RADIUS (or LDAP) user generates a local account providing
"read" permission. A user with "admin" permission may alter the permission
for each 'registered' user (chapter 5.4.6.1.3).
If using LDAP as authorization method, LDAP specific error messages (here e.g.
"Can't contact LDAP server" during login) are passed via pop up window:
If the configured RADIUS (or LDAP) server is not available during login, the local
account is used for authentication.
The local ADMIN user has always access to the device, independent from the
active authorization method.

version.
5.4.6.1.3 User Management
The currently logged in user has to have "admin" permission to access the
User Management entry where users can be added or deleted and the permission
can be modified.
In the next screenshot, a user named TEST with "admin" permission is in the pro-
cess to be restricted to "read/write" permission. After a click on the
button this user will then have all rights but only access to the Password and Language entry within the Setup Tab. A user with "read" permission additionally is not
able to apply any changes within the other tabs of the Web Interface.

5.5 Control via Remote Interface: SNMP
5.5.1 SNMP Overview
The "Simple Network Management Protocol" (SNMP) essentially is a request-reply
protocol running over UDP (usually ports 161 and 162). SNMP is an asymmetric
protocol operating between two types of management units: managers and agents.
A manager is called "Network Management Station" (NMS), which is usually a
computer on which one or more management systems are running. On small NMS,
command line tools can be used. On larger NMS normally third-party software, also
called a "network management suite" collects the data and provides a graphical
user interface.
An agent or SNMP-agent is software, which runs on a "Network Element" (NE).
NEs in a SNMP environment are called "nodes". An agent collects and stores information from the system, translates the information in SNMP-compatible form, and
makes this information available to the manager. The agents manage the "objects"
of the node. Each object has an own individual management "Object ID" (OID).
In the system, the objects are the variables, which can be simple values or tables.
The object information is stored in the "Management Information Base" (MIB).
Note:
The iReasoning MIB Browser Personal Edition (including Trap Receiver) by
iReasoning Inc. is recommended to test the communication via SNMP.
5.5.2 Private Enterprise Number, Device Index Number
The Private Enterprise Number of DEV Systemtechnik GmbH is 21035.
This MIB is designed in SNMP v2 compliant format starting with the object sections
.sysDevModules and .devSysMibConformance, which are not described in this
context.
The actual MIB content for DEV Systemtechnik power systems starts with the
object section .dev-5071, which has the Device Index Number 34.
This concatenates to the string (i.e. the numerical OID: .1.3.6.1.4.1.21035.34):
The intention for this MIB design was to keep the structure compatible with the
predecessor MIB, which was designed for the DEV 5071 (thus, the name of the
above mentioned object section). To support the extended functionality of the
DEV 5072 the MIB was supplemented with a few OIDs.

5.5.3 The dev-5071 MIB Tree
The MIB is stored on the controller of the device and can be downloaded via the
SNMP setup of the Web Interface (please refer to chapter 5.4.6.2.2) or directly with
a web browser via the link:
http://<IP-of-the-device>/devPower.mib
As shown above, the section .dev-5071 is divided into four branches:
• .devPowerTraps (chapter 5.5.4.1),
• .instrument (chapter 5.5.4.2),
• .application (chapter 5.5.4.3), and
• .surveillance (chapter 5.5.4.4).
In the corresponding sub-chapter, the content of each branch is shown expanded
and each object within a branch is described.
5.5.4 MIB Objects
In the following, the objects of the section .dev-5071 in the MIB tree are described.
The complete name of a MIB object results out of the concatenation of the MIBstring (please refer to chapter 5.5.2):
• And some objects can be modified in all modes of operation:
• .application.controlMode chapter 5.5.4.3.1
• .surveillance.trapEnableMask chapter 5.5.4.4.1
• .surveillance.errorEnableMask chapter 5.5.4.4.2

5.5.4.1 .devPowerTraps
Aside from the SNMP standard trap 'Cold Start Trap', this MIB additionally supports
three specific traps.
Note:
By default, all traps are disabled.
By setting the corresponding bit in the .trapEnableMask (please refer to
chapter 5.5.4.4.1) each trap can be enabled individually.
Traps for specific error classes can be masked out by clearing the appropriate
bits in the .errorEnableMask (chapter 5.5.4.4.2).
5.5.4.1.1 .devPowerTraps.trapAlarmText
This trap (number 3, OID: .1.3.6.1.4.1.21035.34.0.3) is triggered if the device
detects a new error. It delivers the appropriate error message (please refer to
chapter 6.1) obtained via .errorDescription (chapter 5.5.4.4.5).
To enable the trap, bit 6 (enum: errortext) in the .trapEnableMask is to be set.
5.5.4.1.2 .devPowerTraps.trapAlarm
This trap (number 4, OID: .1.3.6.1.4.1.21035.34.0.4) is triggered if the device either
detects a new error or if a pending error disappears. The trap delivers .errorNr
(please refer to chapter 5.5.4.4.4.2) and .errorPending (chapter 5.5.4.4.4.5) for the
corresponding entry in the .errorTable.
Bit 5 (enum: error) in the .trapEnableMask is to be set to enable the trap.
5.5.4.1.3 .devPowerTraps.trapModeChange
This trap (number 5, OID: .1.3.6.1.4.1.21035.34.0.5) is triggered if the device
detects that an operation mode change was performed. The trap delivers
.controlMode (please refer to chapter 5.5.4.3.1).
To enable the trap, bit 4 (enum: modechange) in the .trapEnableMask is to be set.

Explicit FTPS (Port 21 (Control), Port 20 (Data)) and
implicit FTPS (Port 990 (Control), Port 989 (Data)) are supported.
If in the HTTPS/FTPS entry (chapter 5.4.6.2.3)…
- …"Enable HTTPS/FTPS" is unchecked:
The FTP-server listens on Port 21 only. The AUTH TLS command (for explicit
TLS) is not accepted.
- …"Enable HTTPS/FTPS" is checked and "Disable HTTP/FTP" is unchecked:
The FTP/FTPS-server listens on Port 21 (unencrypted and via explicit TLS)
and on Port 990 (implicit TLS, with PROT C and PROT P supported).
- …"Enable HTTPS/FTPS" is checked and "Disable HTTP/FTP" is checked:
The FTPS-server listens on Port 990 (implicit TLS) only. Additionally, the
data channel (Port 989) has to be encrypted; PROT C is not accepted, i.e.
the FTPS-client has to send a PROT P to the FTPS-server.

6 Error Indication
The indication of an error is realized via hardware, i.e. via LEDs (at the power supply
modules plus the "Status" LED) and additionally via software, i.e. via Web Interface
and/or via SNMP.
The hardware indication via LEDs is described in chapters 3.1.2 & 5.3. For the
indication via Web Interface please refer to chapters 5.4.3 & 5.4.5 and the
indication via SNMP is explained in chapters 5.5.4.1 & 5.5.4.4. The software error
indication (i.e. the error codes) is described in the following.
6.1 Software Error Indication
The device is capable to detect several types of errors that are reported to the
Web Interface and to the M&C system. Either the M&C system has to poll the
device for these errors or it is informed via an alarm trap, assuming that the specific
SNMP trap is enabled.
6.1.1 Power Errors
For the DEV 5072 chassis error indication is provided for
- "Output Sum Voltage Error": this warning is reported if the measured output voltage deviates from
the defined output voltage (please refer to chapter 5.4.4)
- "Total Current Limit Error": this warning is reported if the measured output current exceeds the
defined maximum output current (chapter 5.4.4)
In addition, there are several error codes for the installed 1…4 power supply
modules that are reported if the surveillance of the related power supply module is
enabled (chapter 5.4.4.1):
- "AC Line [i] Low Error": if the input voltage of the module is not within specifications
- "Power Module [i] Error": if there are e.g. communication problems with the module
- "Power Supply Temperature [i] Error": if the power supply module was turned off due to the temperature of
the power supply module being too high
- "Output [i] Voltage Error": if the output voltage of the power supply module exceeds the defined
output voltage
- "Power Supply Temperature [i] Alarm": this warning is reported if the temperature of power supply
module is too high
- "Power Supply [i] not present": if a power supply module is detected as not present
- "Error PowerModule [i] OV Protection": if the overvoltage protection is activated
- "Key Matching Error [i]": if the applied power supply module type is not supported
- "Nominal Voltage Error [i]": if the power supply module type does not match the output voltage
configured for the DEV 5072 chassis
