ABB Electrical OS30AJ12 General Purpose Switch

Model Type: 1SCA022548R9810 Electrical  General Purpose Switch

Connectors and Indicators

The switch consists of four equal RJ45 Ethernet ports, a SDSL

transceiver, and an RS-232 interface for configuration and transmission of serial data. Each RJ45 port can be connected to Cat. 3 (10 Mbps)

or Cat. 5 (100 Mbps) Ethernet cable connections up to 100 meters. The cables can only be used for internal connections.

Crossover cables are not required because the RJ45 ports of the 560NMS34 switch support automatic MDI/X.

The SDSL interface can be connected to customer-provided two-wire copper cable.

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

Depending on the distance, the transmission rate

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

The status of a port can be indicated by two LEDs.

These are located above and below the RJ45.

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 is 100 Mbps

DSL (via backplane)

The status of the DSL interface is indicated by the green LED labeled

The status of the DSL interface can be monitored by the green LEDs labeled A1 (active) and L1 (linked).

L1 Status:

- Off - no DSL link

- On - DSL link established

A1 Status:

- Off - no DSL connection

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