HIRSCHMANN RS2-FX/FX Industrial Switch Module

. Functional description

The 10/100BASE-T(X) ports of a RS2

xTX/xFX EEC represent a terminal connec

tion for the connected LAN segment. You

can connect single devices or complete net

work segments.

1.1 FRAME SWITCHING FUNCTIONS

Store and Forward

All data received by the RS2-xTX/xFX EEC

from the system bus or at the ports is

stored and checked for validity. Frames

> 1536 bytes as well as fragments (< 64

bytes) are discarded. The RS2-xTX/xFX EEC

forwards the valid frames.

Multi address capability

A RS2-xTX/xFX EEC learns all source

addresses per port. Only packets with– unknown addresses– addresses learnt at this port– a multi/broadcast address

in the destination address field are sent to

this port.

A RS2-xTX/xFX EEC learns up to 1.000

addresses. This becomes necessary if more

than one terminal device is connected to

one or more ports. In this way several inde

pendent subnetworks can be connected to a

RS2-xTX/xFX EEC.

Learnt addresses

A RS2-xTX/xFX EEC monitors the age of the

learned addresses. The RS2-xTX/xFX EEC

deletes address entries from the address

table which exceed a certain age (300

seconds).

Note: Restarting deletes the learned

address entries.

Tagging (IEEE 802.1Q)

The IEEE 802.1 Q standard designates the

VLAN tag to be included in a MAC data

frame for the VLAN and prioritizing func

tions. The VLAN tag consists of 4 bytes (2

bytes tag protocol identifier TPID, 2 bytes

tag control information TCI). It is inserted

between the source address field and the

type field. Data packets with a VLAN tag are

transmitted unchanged by the RS2-xTX/xFX

EEC.

1.2 SPECIFIC FUNCTIONS OF THE

TP/TX INTERFACE

Link control

The RS2-xTX/xFX EEC monitors the connec

ted TP/TX line segments for short-circuits or

interrupts using regular Idle signals in

accordance with IEEE standard 802.3

10/100BASE-T/TX. The RS2-xTX/xFX EEC

does not transmit any data to a TP/TX seg

ment from which it does not receive an Idle

signal.

Note: A non-occupied interface is assessed

as a line interrupt. The TP/TX line to termi

nal equipment which is switched off is like

wise assessed as a line interrupt as the  de

energised bus coupler cannot transmit Idle

signals.

Auto polarity exchange

If the receive line pair is incorrectly connec

ted (RD+ and RD- switched) polarity is auto

matically reversed.

Autocrossing

The RS2-xTX/xFX EEC detects the transmit

and receive pairs (MDI, MDI-X). The

RS2-xTX/xFX EEC automatically con

figures its port for the correct transmit and

receive pins. Consequently it does not

matter whether you connect devices using

a cross-over or straight cable.

1.3 SPECIFIC FUNCTIONS OF THE

F/O INTERFACE

Link control

The RS2-xTX/xFX EEC monitors the connec

ted F/O line for interrupts using idle signals

during frame pauses in accordance with

IEEE standard 802.3 100BASE-FX. The

RS2-xTX/xFX EEC transmits no data to a F/O

line from which it is receiving no idle signal.

Low Light Detection

If the optical input power decreases below

the low light threshold the transmit and

receive path will be disabled for data and

the idle signal will be transmitted.
