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
.
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.
