Switch 560NMS34 Data sheet

1 RTU560 product line Switch Data sheet Characteristics For documentation purposes, the ports are labeled from 1 to 4. The SDSL port is connected through the backplane. There is no specific uplink port. All ports are equal in function. Link and speed status of each and the SDSL port are displayed by status indicators (refer to Connectors and Indicators). The switch learns addresses by analyzing received frames and stores them in a lookup-table (max entries), which is used to forward frames only to the correct port. If it is broad- or multicast or if the target address is not found in the lookup-table, a received frame is forwarded to all ports except the receiving one. If an entry in the lookup-table is not refreshed by an incoming frame with the specific source address, it is aged out within a maximum of 304 seconds (by default, value is configurable). Application The RTU component is a managed plug and play Layer-2-switch providing 4 fast auto-negotiating - ports with auto MDI/X (automatic crossover detection and correction) and one 2-wire SDSL-port for use with private copper cables. It can be used with rack types 560MPR01, 560MPR03 and 560SFR02. The switch is intended for distributing within a station through the -ports. The SDSL-port can be used for interconnecting stations with a maximum distance of 20 km (copper cable with diameter of 0.8 mm). The switch is able to provide redundant topologies by the (Rapid) Spanning Tree Protocol. The switch supports VLAN frames and tunneling of serial data. Regarding IEEE 802.1Q VLAN frames, the switch can be configured to VLAN or transparent mode. In transparent mode the switch will never change any frame or TAG of a frame; in VLAN mode it can be configured to support several applications like trunk or access ports. Quality-of-Service is supported by the switch if an IEEE 802.1p compliant frame format is used. The switch can separate frames into up to four queues, which can be configured to priority based or weighted-fair queuing. The uses a power supply voltage of 5 V that can be set to the internal RTU supply or external supply via a Jumper. The component itself, the ports as well as the SDSL connection and RS232 interface are hot-plug capable.

Connectors & Indicators The switch consists of four equal ports, one SDSL transceiver and a RS-232 interface for configuration and tunneling of serial data. Each port can be connected with a Cat. 3 (for 10 Mbps) or Cat. 5 (for 100 Mbps) cable with a maximum length of 100 meters. The cable should only be

2 used for in-house connections. Since Auto MDI/X is supported by the switch for the ports, there is no need for crossover cables. The SDSL interface can be connected to 2-wire customer-owned copper lines. The maximum bridgeable distance is 20 km for 0.8 diameter copper cable with a transmission rate of 192 kbps. Depending on the distance, the transmission rate can be configured to up to 11 Mbps. The status of any switch port can be signalized by two LED indicators, which are located in each above and below. () A green Link LED (labeled L) indicates an active connection. Activity status: Off - No Connection On - Connection Established (Link) Flashing - Activity (Transmission or Reception of Frames) A yellow Speed LED (labeled S) indicates a 10 or 100 Mbps connection. Speed status: Off - Speed of 10 Mbps On - Speed of 100 Mbps DSL (via backplane) The state of the DSL interface can be monitored through the green LEDs labeled A1 (Activity) and L1 (Link). L1 status: Off - No DSL connection On - DSL link established A1 status: Off - No DSL connection Flashing - DSL activity (Transmission or Reception of Frames). DSL connection negotiation if Link is off. RS232 (via backplane) The RS232 port can be accessed via the backplane. There are no optical indicators. General Detected errors are signalized by a red Error LED (labeled ERR) together with an Alarm condition. The alarm condition can also be signalized by an isolated alarm relay, which can be deactivated by a jumper. The conditions that lead to an alarm state can be configured. Topology The provides a total of five ports for use with end devices, switches, bridges, hubs androuters using the DSL port. Star, ring or line topologies can easily be built by this family of switches. Redundant topologies are automatically detected and handled by the Rapid Spanning Tree Protocol (RSTP). This is fully backward compatible with the wide-spread Spanning Tree Protocol (STP). Switch SDSL SDSL Figure 2: Typical topology for use with Management and Configuration Device Management and Configuration of the can be done by Telnet, Secure Shell (SSH), SNMP, RS232 or Web-interface. All methods can be used to either read or write parameters of the device. Additionally the interface and alarm state of the device can be monitored by IEC or By default, the IP address for the configuration of a switch is with a subnet mask of and a gateway of The SNMP strings are public for read-only access and private for read-write operations. Resets to default values could be done via RS232 interface, while press i during startup process. Connections for configuration purposes are accepted through any interface. All ports are administratively up in default state. The preconfiguration for the RS232 interface is baudrate 57600, 8 databits, no parity, 1 stopbit (57600, 8N1). The command-line interpreter for configuration via this interface can be accessed by any terminal software (e.g. Hyperterminal). Ports All ports of the device can be disabled or enabled by configuration. Furthermore, the speed and duplex of any port can be set according to its capabilities. This is 10 or 100 Mbps, Full or Half duplex for the ports and 192 kbps up to 11 Mbps in steps of 8 kbps for the SDSL port. It is also possible to use an auto-detect setting. For the SDSL port it is recommended to set the device closer to the control center to a fixed speed setting, while setting the communication partner at the RTU side to auto-detect. Ports connected to a RTU from RTU500 series should be configured with auto detect. The switch supports a multiple of additional features, like port mirroring, bandwidth control, or quality of service. 2 1KGT V Switch

3 Alerts, Notifications and Logging The provides Syslog and SNMP capabilities to send alerts and notifications to one or more predefined destinations. There is also a relay for configurable out-of-band alerts. For each Syslog server entry a severity can be entered to filter outgoing messages. A system log stores critical messages. The log can be accessed by Telnet and implements a timestamp either by uptime, or date and time if a time server is configured. For Syslog and local logging, a SNTP time server can be used to synchronize clocks and to enable the generation of date and time timestamps instead of uptime related messages. Redundancy Support The redundancy protocols Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) are fully supported. Without configuration RSTP is enabled for all ports. Switching from RSTP to STP is done automatically to ensure the compatibility to existing STP installations. For every port, the (R)STP parameters can be configured separately. This includes port priority for root bridge control as well as point-to-point and edge connection settings. A global bridge priority is also settable. Authentication Access to the Telnet and SSH interface of the is controlled by a two-level password protection. The first level enables the user to access parameters in read-only mode and has to be entered as soon as a connection is established. To read and write parameters, the device has to be put in a configuration mode that requires an additional password. Any password can be disabled. Some security sensitive information, such as the configuration file, may not be available in read-only mode. Besides the two-level password protection, users may be authenticated by a standard RADIUS server. Switch - 1KGT V
