3.Assembly, startup procedure and dismantling

3.1 UNPACKING, CHECKING

-Check whether the package was delivered complete (see scope of delivery).

-Check the individual parts for transport damage.

Warning

Use only undamaged parts!

3.2 ASSEMBLY

The equipment is delivered in a ready-to-operate condition. The following procedure is appropriate for assembly:

-Check whether the switch factory-setting is suitable for your requirements.

-Pull the terminal block off the Transceiver 100 Mbps TX/FX and wire up the supply voltage and indicator lines.

-Fit the Transceiver 100 Mbps TX/FX on a 35 mm ISO/DIN rail to DIN EN 50 022.

-Suspend the upper snap-in hook of the Transceiver 100 Mbps TX/FX in the ISO/DIN rail, insert a screwdriver horizontally under the housing into the locking slide pull this downwards (see Fig. 6, dismantling) and press the bottom of the module onto the ISO/ DIN rail until it locks in position (Fig. 5).

-Fit the signal lines.

Notes:

-The front panel of the Transceiver 100 Mbps TX/FX is grounded via the separate ground connection in the front panel.

-The shielding ground of the twisted pair lines which can be connected is electrically connected to the front panel.

3.3 STARTUP PROCEDURE

You start up the Transceiver 100 Mbps TX/FX by connecting the supply voltage via the 5-pin terminal block. Lock the terminal block with the locking screw at the side.

F/O-Line

For a F/O segment the Transceiver 100 Mbps TX/FX has one port with an SC socket.

The maximum length of an attached F/O segment is:

-3000 m at 50/125 µm fiber type (Transceiver 100 Mbps TX/FX),

-3000 m at 62.5/125 µm fiber type (Transceiver 100 Mbps TX/FX).

TP-Line

For a TP segment the Transceiver 100 Mbps TX/FX has one port with an TP socket.

The maximum length of an attached TP segment is 100 m.

Propagation delay with half duplex segments Using half duplex segments the propagation delay between the terminal devices is 512 bit times (BT) maximum. Add all components of the signal path plus a safety margin.

Propagation delay in the signal path:

Components	Delay
Transceiver 100 Mbps TX/FX	84 BT
Class II Repeater	92 BT
DTE with TP connection	50 BT
DTE with F/O connection	50 BT
Cat. 5 TP cable	1.112 BT/m
F/O cable	1.0 BT/m
Security margin	4 BT

3.4 DISMANTLING

To take the Transceiver 100 Mbps TX/FX off the ISO/DIN rail, insert a screwdriver horizontally under the housing into the locking slide, pull it downwards and tilt the Transceiver 100 Mbps TX/FX upwards (Fig. 6).
