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

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).
