To avoid contact resistance only use clean, corrosion-free DIN rails. End clamps can be mounted on both sides of the module to stop the modules from slipping on the DIN rail. 4.1 1. 2. 3. 4.2 1. 2. 3. 4.3 Assembly Place the module onto the DIN rail from above. The upper holding keyway must be hooked onto the top edge of the DIN rail. Push the module from the front towards the mounting surface. Once the module has been snapped on properly, check that it is fixed securely on the DIN rail. Removal Pull the locking latch down using a screwdriver, needle-nose pliers or similar. Pull the bottom edge of the module away from the mounting surface. Pull the module diagonally upwards away from the DIN rail. Connecting the 24 V DC supply voltage The SMCS is operated using a 24 V DC voltage, which is applied via COMBICON. If required, the voltage can also be supplied redundantly If redundant supply voltage monitoring is active (default setting), an error is indicated if only one voltage is applied. A jumper between US1 and US2 prevents this error message. It is also possible to deactivate monitoring in webbased management or via SNMP.

To avoid these dangers, correct installation, taking the local conditions into account, is vital. All Factory Line devices must be grounded so that any possible interference is shielded from the data telegram and discharged to ground potential. A wire of at least 2.5 mm2 must be used for grounding. When mounting on a DIN rail, the DIN rail must be connected with protective earth ground using grounding terminal blocks. The module is connected to protective earth ground via the metal base element. MODE FL SWITCH SMSC 8GT Ord.

The function of the second LED (MODE) for each port can be set using the MODE switch (see also example below). There are three options: ACT (Activity) Green SPD (Speed) Green/ orange ON Sending/receiving telegrams OFF Not sending/receiving telegrams ON (orange) 1000 Mbps ON (green) 100 Mbps FD (Duplex) 4.10 Green OFF 10 Mbps if Link LED is active ON Full duplex OFF Half duplex IP address assignment Two mechanisms are available for the assignment of the IP address: BootP or via the V.24 (RS-232) interface. By default upon delivery, the IP address is assigned via BootP. The Factory Manager configuration software has been optimized for use with Smart Managed Compact Switches and is the easiest way to assign the IP address. The assignment mechanism can be modified via web-based management or via the V.24 (RS-232) interface. 5 Hardware functions "Store and forward" Ethernet switching All data telegrams that are received by the switch are saved and their validity is checked. Invalid or faulty data packets (> 1522 bytes or CRC errors) and fragments (< 64 bytes) are rejected. Valid data telegrams are forwarded by the switch. The switch always forwards the data using the data transmission speed that is used in the destination network segment. Multi-address function The switch independently learns the addresses for termination devices, which are connected via a port, by evaluating the source addresses in the data telegrams. Only packets with unknown addresses, with a source address of this port or with a multicast/broadcast address in the destination address field are forwarded via the corresponding port. The switch can store up to 4000 addresses in its address table with an aging time of approximately 40 seconds. This is important when more than one termination device is connected to one or more ports. In this way, several independent subnetworks can be connected to one switch. 7593_en_00 PHOENIX CONTACT 9 FL SWITCH SMCS 6GT/2SFP Diagnostics via the alarm contact If either or both of the supply voltages fails, the alarm contact opens. On a restart, the switch executes a hardware selftest. In the event of an error during the selftest, an SNMP trap is transmitted. Status and diagnostic indicators These indicators provide information about the status of the SMCS at all times. Local diagnostics without additional tools is possible thanks to numerous LEDs. Auto crossing Due to auto crossing of the transmit and receive cables of a twisted pair interface, it is no longer necessary to distinguish between 1:1 and crossover Ethernet cables. Auto negotiation Auto negotiation is a method whereby the switch automatically detects the operating parameters for the connected network and sets the corresponding parameters (10 Mbps/100 Mbps/1000 Mbps data transmission rate and half/full duplex transmission mode) for its RJ45 ports. Automatic port setting eliminates the need for manual intervention by the user. The auto negotiation function can be activated/deactivated via the web interface. 6 Software functions 6.1 SNMP SNMP (Simple Network Management Protocol) can be used to monitor Ethernet communication even via network management systems. Management systems, such as a PC with Factory Manager, can read and modify configuration and diagnostic data from network devices via SNMP. Supported MIBs: Management Information Base II (MIB 2) according to RFC1213, LLDP MIB, RSTP MIB, RMON MIB (only group statistics), bridge MIB (groups: dot1dStp, dot1dBase, dot1dTpAgingTime, and private MIBs). 6.2 IEEE 802.1w - Rapid Reconfiguration Spanning Tree Protocol (RSTP) Rapid Spanning Tree is a procedure enabling the use of redundant Ethernet structures. Via RSTP, the meshed topologies of redundant structures are suppressed logically and converted acyclically to tree structures. In meshed networks, two nodes may be connected in two or more ways (loop). Due to these loops, data packets would circle endlessly in the network. This is why these loops are replaced by a logical deterministic path using an RSTP algorithm. The loops are eliminated by temporarily switching off the individual switch ports in a specific way. All active ports as well as deactivated ports receive data packets. However, the data packets are only forwarded by active ports. The deactivated ports operating in hot standby mode are reintegrated into the network, if required, by modifying the network topology. 6.3 Web-based management In addition to management via SNMP, the switch also supports integrated web-based management. This provides detailed diagnostic and configuration options for startup, operation, and in the event of an error, as well as comprehensive network and device information. 6.4 Use of the Smart Mode Smart Mode allows the user to change the operating mode of the switch by pressing the mode button. Thus it is possible to change the operating mode without accessing the web-based management. The operating mode can be changed with the following sequences: – Activating the Smart Mode – Selecting the desired operating mode – Storing the selected operating mode by exiting the Smart Mode 7593_en_00 PHOENIX CONTACT 10 FL SWITCH SMCS 6GT/2SFP The SMCS offers the following settings with the Smart Mode: – Resetting to default settings – Activating the PROFINET mode – Exiting the Smart Mode without changes Activating the Smart Mode After the boot phase of the switch, the mode button must be pressed for more than five seconds. The three LEDs below the mode button blink when the Smart Mode is active. When the Smart Mode becomes active the switch is in the "Exit without change" status. Selecting the operating mode As soon as the Smart Mode was called, the setting is selected by pressing the mode button shortly. After having selected the desired setting, exit the Smart Mode and the selected status is stored. Exiting the Smart Mode To exit the Smart Mode keept the mode button pressed for more than three seconds. The operating mode selected last is accepted and activated. Possible operating modes in the Smart Mode The SMCS supports selection of the following operating modes in the Smart Mode (see also example below): Mode ACT LED 1 SPD LED 2 FD LED 3 Exiting the Smart Mode without changes OFF OFF ON Resetting to default settings OFF ON OFF Activating the PROFINET mode OFF ON ON 7 PROFINET Physical Device (PDEV) General function description The PDEV function provides an extended scope of functions for switches in PROFINET mode. This includes displaying neighbor and topology information in the engineering tool. This information is determined using the Link Layer Discovery Protocol (LLDP) and can be used to compare the desired and actual network. In addition, the PDEV function is used to display the transmitted information via the Ethernet ports. The PDEV function uses two new submodules: – Interface submodule with port number 0x8X00 (X: 0 to F) – Port submodule with port number 0x8IXX (I: Interface ID; X: Port number) These submodules are represented in the Step7 engineering tool. PROFINET communication enables information about the port speed, duplex mode, and the link status to be read. An engineering tool reads and then displays the neighbor and topology information via SNMP. 7593_en_00 PHOENIX CONTACT 11 FL SWITCH SMCS 6GT/2SFP PROFINET stack and PDEV function The PDEV function is supported by PROFINET stack Version 2.2. The following functions are supported by PN stack 2.2: – Link status, port mode, and port MAC address can be requested via the port – Storing of PDEV data – Reorganization of submodules for integrating interfaces and new ports – Use of the PN stack LLDP in PN mode (used for neighbor and topology detection) – Support for device replacement and application redundancy PDEV in the Firmware The PDEV function can be used for the FL SWITCH SMCS device range in firmware Version 2.2 or later. In addition, the corresponding version of the GSDML file must be used (the FDCML file does not support PDEV at present). These files are used to describe the device function and can be imported into an engineering tool. 8 Housing dimensions Depth 69 mm from top edge of DIN rail 128 mm / 5.04 in. 69 mm / 2.72 in.
