Port Disablement

4.6.1

Disabling Physical Ports

It is possible to disable unused physical ports. A level 3 password is needed to perform this
action.
To prevent accidental disabling of a port, a warning message is displayed according to
whichever port is required to be disabled. For example if rear port 1 is to be disabled, the
following message appears:
There are between two and four ports eligible for disablement:
• Front port
• Rear port 1
• Rear port 2 (not implemented on all models)
• Ethernet port (not implemented on all models)
Note: It is not possible to disable a port from which the disabling port command originates.
4.6.2

Disabling Logical Ports

It is possible to disable unused logical ports. A level 3 password is needed to perform this
action.
Note: The port disabling setting cells are not provided in the settings file.
If it is not desirable to disable the Ethernet port, it is possible to disable selected protocols on
the Ethernet card and leave others functioning.
Three protocols can be disabled:
• IEC 61850
• DNP3 Over Ethernet
• Courier Tunnelling
Note: If any of these protocols are enabled or disabled, the Ethernet card will reboot.

Logging out

If you have been configuring the IED, you should 'log out'. You do this by going up to the top
of the menu tree. When you are at the Column Heading level and you press the Up button,
you may be prompted to log out with the following display:
You will only be asked this question if your password level is higher than the fallback level.
If you confirm, the following message is displayed for 2 seconds:
REAR PORT 1 TO BE
DISABLED.CONFIRM
Caution Disabling the Ethernet port will disable all Ethernet based
communications.
