If a port is logged off, it will probably be removed and need to be restarted.
Go to TCL and type PID XXX(port#) <ENTER>. If the value is zero then the PIB (Port) is inactive.
To restart this PIB, type:
!exec d3 –n pick0 850 –phantom & <ENTER>
*must be typed in lower case
Then type PID XXX (port#) <ENTER> to verify it is working. If the value is a number other than zero port is active. You also type PID * <ENTER> to see all active Ports or Pibs.
