Replacing the Network Switch

The  internal  network  switch,  which  distributes  the  ETHERNET  A  connections,  is  mounted  inside  the  control
surface below the Overbridge. Internally, it is located to the right of the Local IO unit:

To replace the switch, you will need to remove the Central Panel,  Central  GUI  display  and  Overbridge  blanking
panel.

DO NOT 

attempt to open the frame without first disconnecting the mains supply. 

1.

Remove the Central Panel, Central GUI display and Overbridge blanking panel as described earlier. See

Replacing a Panel

 and 

Replacing a TFT Display

.

In each case, the panel should be removed completely. You will see the network  switch  mounted  at  the  rear  of
the frame.

2.

Disconnect all of the internal connectors from the front of the unit, taking note of where each one should

be fitted.

There are several RJ45 network connectors on the left plus a single power connector on the right.

3.

Now loosen the unit from the console frame. There are two hex nuts on each side of the unit holding it in

place.
