3. Router Description

LAN Industrial router SmartFlex SR300 is an ideal device for the realization of a secure
connection of two local area networks (LANs). Interconnection is carried out using two ETH­ERNET 10/100 interfaces and secure tunnel (IPSec, OpenVPN, L2TP).

The other equally important ways to use this router is to connect any device with RS232,
RS485 or I/O interface to the local network (LAN). For this purpose, SmartFlex SR300 is
equipped with two ETHERNET 10/100 ports and other interfaces based on the version of the
router chosen by the user.

As a standard, this router is equipped with two ETHERNET 10/100 ports, one USB 2.0
Host port, two binary inputs and one output (I/O connector). An integral part of the router is
also a memory card reader placed on the rear panel. This reader allows SmartFlex SR300 to
operate with microSD cards and increase storage space of the router up to 64 GB (32 GB in
case of SDHC cards). The router can be equipped with WiFi module on customer’s request,
however it is not possible to order it and add to the router later. The router can be equipped
with PoE PD (Power over Ethernet – powered device) to power the router via Ethernet, or
PoE PSE (power source equipment) to power other devices by the router. Richer range of
interfaces is available in versions containing three switched Ethernets. SmartFlex SR300 is
supplied either in a plastic or metal casing, based on the requirements of the customer.

For configuration of the industrial router is available web interface protected by password.
Web interface provides (after logging in) detailed statistics about the router activities, signal
strength, detailed system log etc. This device supports the creation of VPN tunnels using tech­nologies IPSec, OpenVPN and L2TP for secure communications. There are also supported
functions such as DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS, backup primary
connection and many other functions.

Other diagnostic functions ensuring continuous communication include hardware watch­dog which monitors the status of the router. Using a special window (start up script window)
you may insert Linux scripts for various actions. For some applications is crucial the possibility
to create several different configurations for one router. These configurations can be switched
as necessary (for example using SMS, binary input status, etc.). SmartFlex routers may auto­matically upgrade configuration and firmware from server. This allows mass reconfiguration of
many routers in one time.

The router also supports additional software like R-SeeNet for permanent traffic monitoring
of routers.

5.5 Mounting recommendations

• Possibility to be put on a work surface,

• DIN rail EN 60715 with included plastic or metal clip.

For the most of applications with a built-in router in a switch board it is possible to recognize
two kinds of environments:

• no public and industry environment of low voltage with high interference,

• public environment of low voltage without high interference.

For both of these environments it is possible to mount router to a switch board, the following
there is no need to have examination immunity or issues in connection with EMC according to
EN 60439-1 ed.2:00 + A1:04.

Attention: If the negative pole of the router is grounded, there is no protection against
reversed polarity!

Compliance of EN 60439-1 ed.2:00 + A1:04 specification it is necessary to observe next
assembly of the router to the switch – board:

• For every cables we recommend to bind the bunch, we recommend for this use:

– Length of the bunch (combination of power supply and data cables) can be maxi-

mum 1.5 m. If the length of data cables exceeds 1.5 m or in the event of, the cable
leads towards the switch – board. We recommend installing over – voltage protec­tors (surge suppressors).

– With data cables they mustn’t carry cables with reticular tension ∼ 230 V/50 Hz.

10

SmartFlex SR300

• Sufficient space must be left before individual connectors for handling of cables,

• For correct function of the router we recommend to use in the switch-board earth-bonding

distribution frame for grounding of power supply of router, data cables and antenna.

5.6 Removal of the DIN rail

The DIN holder is suitable for a DIN rail according to EN 60715 standard only. The default
position of plastic or metal holder, which is used for mounting the router on a DIN rail, is shown
in the following figure. Its position can be changed on some models (back or bottom). When
changing the position of the DIN holder, tighten the screws with max. 0.4 Nm torque.

Figure 8: Default position of DIN holder

In order to remove the DIN rail it is necessary to lightly push the router upward so that the
top part of the DIN holder hitched to the DIN rail comes out of this rail, then fold the top of the
router away from the DIN rail.

Unit has to be supplied by a power supply specified as a Limited Power Source (LPS) ac­cording to clause 2.5 of IEC/UL 60950-1 or CEC/NEC Class 2 source of supply as defined
in the Canadian Electrical Code, CSA C22.1 and National Electrical Code, ANSI/NFPA 70. If
the power supply/cable provided with device is not used, always use the cables with minimum
wire size (nominal cross section) 0.5 square mm for power supply.

The power supply for the router must be between +10 V to +60 V DC supply. Protection
against reversed polarity without signaling is built into the router. Note: The protection against
reversed polarity is lost if the negative pole is grounded!

The router can be put into low power mode using a special command lpm. It can then be
awakened, for example, by an activity on binary input or using an internal timer. Consumption
in LPM mode may vary depending on the configuration of the router.

Circuit example:

Figure 12: Connection of power supply

Note for PoE: See Chapter 5.8.6 for information on how PoE versions of the router
impact the power supply usage. The power supply for a PoE PSE router has to meet
other specific requirements.

5.8.6 Power over Ethernet (PoE)

On the router models with PoE, the PoE+ standard IEEE 802.3at-2009 and PoE standard
IEEE 802.3af-2003 are supported in both Ethernet ports (ETH0, ETH1). The PoE PD version
allows the router to be powered over the Ethernet by another PoE PSE device. The PoE PSE
version also allows the router to power other devices over the Ethernet.

PoE PD

Figure 17: PoE PD usage

The PoE PD parameters can be found in Chapter 7.6. The POE LED on the front panel
of the router lights up green when voltage is present in an Ethernet port so the user knows
the router can be PoE powered. You can still power the router with this connector even if the
router is powered with PoE (in PoE PD version), but the input voltage must be higher than
15 V DC. If the input voltage is lower than 15 V DC and the PoE voltage is present (PoE LED
green on), the router will still be powered from the Ethernet connector via PoE.

Note: You can not power the router via the ETH2 ports on the SWITCH router version.
The PoE PD is available on the ETH0 and ETH1 ports only.

18

SmartFlex SR300

PoE PSE

Figure 18: PoE PSE usage

The power supply used with the PoE PSE router has to provide voltage from 44 to
57 V DC and the output power has to be at least 65 W for full PoE+ use (Class 4) in
both Ethernet ports (ETH0 and ETH1).

The PoE PSE parameters can be found in Chapter 7.6. The PoE state is indicated by the
POE LED on the front panel of the router, see Chap. 5.8.1. When sufficient voltage (44 to
57 V) and power is available is indicated by the green light. A yellow POE LED indicates
insufficient power or voltage through the PWR connector. When a device is being powered
from the router, the POE LED is will show blinking green. Yellow blinking is shown for an
overload (the powered device is using too much power) or a short circuit (incorrect wiring of
the cable or of the device without PoE support).

You can enable or disable the PoE PSE feature separately on the ETH0 and ETH1 ports
via the Web interface of the router. This can be found in the LAN configuration pages (Primary
for ETH0, Secondary for ETH1). When PoE PSE is enabled, you can find the current, voltage,
power and power class information on the General page of the router’s Web interface. See
the Configuration manual [2]. Via SSH or in scripts you can use the Shell command pse.

5.9 Interfaces Description

There are available versions with one of the following inter faces:

• SWITCH interface

5.9.1 SWITCH interface

Three LAN ports of SWITCH interface for SmartFlex routers (RJ45 connectors for connect­ing Ethernet devices) act as a typical switch device. This means that the router reads Ethernet
frames (data packets on an Ethernet link) from any port on SWITCH interface and transmits
them on other ports of the SWITCH interface. Each port can transmit frames independently
on the other ports. State indication is provided on every connector. Router in this version com­plies with the standards and temperature ranges declared in Chap. 7.1 except for the lower
maximum operating temperature which is +70◦C.

9. Troubleshooting

If you cannot connect to the router from your PC, your network card may be configured
in such a way that it is not possible to connect to the router. Take one or more of the
following steps in order to solve the problem:

• Make sure your PC’s network card is configured to obtain the IP address form the
DHCP server (by default the DHCP server is running in the router).

• Set the communication rate to 10 MB/s in the properties of your network card.

• Connect the router to the PC via Switch.

• Connect the router to the PC, start the router first and then start the PC after the

router’s initialization.

9.1 FAQ

- The router reboots itself and the Ethernet connection fails.

• The router will not work well without an antenna. Keep the antenna as far as possi-

ble from the power supply.

- Ethernet connection fails or is not establishing.

• It is possible to turn auto negotiation off and set a rate and duplex manually on the

Ethernet interface of the router. Available on "LAN Configuration" page in the router.

- I cannot connect from the Internet to the device behind the router. I have NAT

enabled.

• The device’s gateway has to be configured so it points to the router.

- I can’t access my Web server placed behind the router over NAT.

• The remote HTTP access to the router has to be disabled on "NAT Configuration"

page in the router. Also enable "Send all remaining incoming packets to default
server" feature and fill in the IP address of your Web server. On the Web server,
the default gateway has to be the IP address of the router.

- DynDNS doesn’t work.

• If the same IP address is recorded in your canonic name as a dynamically assigned

address, it means that the provider is using NAT or a firewall.

• You can verify NAT using ping to your ser ver with static address and then compare

with router’s IP address.

34

SmartFlex SR300

• You can verify a Firewall by accessing remotely to the router’s Web interface.

• The operator may not provide the address of DNS server and without DNS server’s

address it is impossible to connect to the dyndns.org server. The following mes­sages will be shown in the System Log:

– DynDNS daemon started
– Error resolving hostname: no such file or directory
– Connect to DynDNS server failed

- L2TP or IPSec isn’t establishing.

• Chec k the "System Log" page for error messages.

- IPSec tunnel establishes but the communication does not run.

• Probably there are bad routing rules defined in the connected devices, or the default

gateway.

- Serial communication is not working.

• Verify that the router model supports serial communications. Also verify the serial

communication settings. To do so, open the router’s configuration menu via the
web browser, select the appropriate "Expansion Port" from "Configuration" part of
the menu and verify the settings.

- Is the router Cisco compatible? Can I use the Cisco configuration?

• No, the Firmware in the router (Conel OS) is based on Linux with BusyBox. Thus

the Cisco configuration cannot be used. But network connections are defined by
standards so connecting the router to the Cisco or other networking devices is pos­sible and will be compatible.

- FTP or SFTP does not work

• FTP will work on v2 routers only. You can use SFTP on all routers to transfer files

to/from the router. If having troubles with FTP on v2 routers, make sure you have
FTP enabled: "Configuration" section, "Services", "FTP". Then you can connect
with any client on port 21 with name and password same as for the Web interface.
If having troubles with SFTP, make sure you have SSH enabled: "Configuration"
section, "Services", "SSH". Then you can connect with any client on port 22 with
name and password same as for the Web interface.

- How can I connect to the router’s command line? (SSH, Telnet)

• You can use SSH on all routers or Telnet on v2 routers only. SSH is enabled by

default, but you can verify in Web interface in "Configuration" section, "Services",
"SSH". Then connect with any SSH client on port 22 of the router. User and pass­word is the same as for the Web inter face. Telnet on v2 routers can be enabled
here: "Configuration" section, "Services", "Telnet".
