11.1.3 Replacing the Network Adapter

Spare parts

Network adapter, from item no. 00320413-01

● Unplug the ribbon cable from the front cover (plugs x2-sp;

see Fig. 11.1.1).

● Undo and remove the board’s front cover mounting screws (2 slotted-head

screws).

● Press the holders apart so that the plug-in contacts release. Carefully pull

out the board and place it on an ESD-checked surface.

● Check the jumper setting on the new LAN board and, if necessary, set the

jumpers in the same way they are set on the old board.

● To fit the new board proceed in the reverse sequence of operations.

● Insert the old card into container which will be used for transporting it (for

example, an ESD envelope).

WARNING

Make sure that the ribbon cable on the righthand side of the network board

does not get pinched or damaged.

NOTE

No setting work or modification to the software configuration is required fol-

lowing the installation of the new board.
