ABB 560NMS24 Integrated Managed Switch with 2 SDSL Ports and 4 Ethernet Ports

Applications

The RTU component 560NMS24 is a managed plug-and-play Layer 2 switch that provides four Fast Ethernet auto-negotiating RJ45 ports with automatic MDI/X (automatic cross detection and correction) and two 2-wire SDSL ports for dedicated copper cables.

The 560NMS24 is a managed, plug-and-play Layer 2 switch that provides four Fast Ethernet auto-negotiation RJ45 ports with automatic MDI/X (automatic cross detection and correction) and two 2-wire SDSL ports for dedicated copper cable.

It is designed to be used with dedicated copper cables. It can be used with Rack Models 560MPR01. 560MPR03. and 560SFR02.

The switch is used to distribute Ethernet within the station via RJ45 ports. the SDSL port can be used to connect stations up to a maximum distance of 20 kilometers (with 0.8 mm diameter copper cables).

Longer distances can be realized by cascading several 560NMS24s. The switch provides a redundant topology via (fast) spanning tree protocol. The switch supports VLAN framing and serial data tunneling.

Features

Ethernet ports are labeled 1 to 4 for documentation purposes.

SDSL ports are connected via the backplane.

There are no specific uplink ports. All ports are functionally identical.

The link and speed status of each Ethernet and SDSL port is indicated by status LEDs (see “Connectors and Indicators”).

The switch learns Ethernet addresses by analyzing received frames and stores them in the query.

The switch learns Ethernet addresses by analyzing received frames and stores them in a lookup table (up to 2048 entries),

used to forward frames only to the correct port. If the frame is

widecast or multicast, or the destination address is not found in the lookup table, the received frame is forwarded to the correct port.

then the received frame is forwarded to all ports except the receive port.

Receive port. If an entry in the lookup table is not refreshed by an incoming frame with a specific source address

then it is aged out for a maximum of 304 seconds.

Maximum 304 seconds (default, configurable).

For IEEE 802.1Q VLAN frames, the switch can be configured in VLAN or transparent mode. In transparent mode

the switch does not change any frames or frame TAGs; in VLAN

mode, the switch can be configured to support a variety of applications, such as

trunking or access ports.

The switch will support quality of service if it uses an IEEE 802.1p-compliant frame format.

The switch can support quality of service if the frame format is IEEE 802.1p compliant. The switch can divide frames

into up to four queues, which can be configured as priority queues or weighted fair queues.

The 560NMS24 uses a 5 V supply voltage that can be set to internal RTU power or external RTU power.

It can be set up as an internal RTU power supply or an external RTU power supply via jumpers.

The component itself, the Ethernet port, as well as the SDSL connection and RS232 interface can be used.

The component itself, the Ethernet port as well as the SDSL connection and the RS232 interface are hot-swappable.

Connectors and Indicators

The 560NMS24 switch consists of four equal RJ45 Ethernet ports, two identical SDSL transceivers, and an RS-232 interface.

ports, two identical SDSL transceivers, and an RS-232 interface.

interface for configuring and transferring serial data. Each RJ45 Port

Each RJ45 port can be connected to either Cat. 3 (for 10 Mbps) or Cat. 5 (for 100 Mbps).

Maximum length is 100 meters. Cables

Cables can only be used for internal connections. Due to the automatic

The RJ45 ports of the 560NMS24 switch support automatic MDI/X,

crossover cables are not required.

The SDSL interface can be connected to the customer's own two-wire copper cable. Maximum Bridge Distance

The maximum bridging distance for 0.8-diameter copper cable with a transmission rate of 192 kbps is 20 km.

Depending on the distance, the transmission rate can be configured up to 11 Mbps.

The status of any switch port can be indicated by two LEDs.

The status of a port is indicated by two LEDs.

These are located above and below the RJ45 jacks.

Ethernet (RJ45)

The green link LED (labeled L) indicates that the Ethernet connection is active.

Active:

- Off - no connection

- On - Ethernet connection established (link)

- Blinking - Ethernet activity (transmitting or receiving frames)

The yellow Speed LED (labeled S) indicates a 10 or 100 Mbps connection.

Speed status:

- Off - Ethernet speed is 10 Mbps

- On - Ethernet speed of 100 Mbps

DSL (via backplane)

The status of the DSL interface can be monitored by the green LEDs labeled A (active) and L (link).

The status of the DSL interface is monitored by green LEDs labeled A (active) and L (link). dSL

The LEDs for port 1 are labeled A1 and L1. respectively, and the LEDs for port 2 are labeled A1 and L1. respectively.

The LEDs for DSL port 1 are labeled A1 and L1. and the LEDs for DSL port 2 are labeled A2 and L2.

L1/L2 Status:

- Off - No DSL connection

- On - DSL link established

A1/A2 Status:

- Off - DSL connection

- Blinking - DSL activity (transmitting or receiving frames). If the link is closed, the DSL connection is negotiated.

RS232 (via backplane)

The RS232 port is accessible via the backplane. No light indicator.

There is no light indicator.

General

When an error is detected, the red error LED (labeled

ERR) and alarm status are signaled. Alarm Status

can also be signaled by an isolated alarm relay that can be deactivated via a jumper.

It can be deactivated via a jumper.

The conditions that lead to an alarm condition can be configured.

Topology

The 560NMS24 provides a total of six ports for use with end devices, switches, bridges, hubs, or routers that use DSL ports.

This series of switches makes it easy to build star, ring, or line topologies.

Redundant topologies are automatically detected and processed by the Rapid Spanning Tree Protocol (RSTP). It is fully backward compatible with the widely used Spanning Tree Protocol (STP).
