For Hardware Fail Flash (HFF) Controllers Only (non UK only):
If the controller needs to be changed to HFF after being installed (non UK only) the following
procedure must be followed:
• Ensure that the power to the controller is switched off
• Move the "Flash" switch (S3) on the CPU Card to its non-HFF position
• Ensure that the link on the HPU is in the HFF position
• Run the Controller Self-Test and confirm that it indicates that the controller hardware is
set up for HFF. Note that the signals will not flash when the controller is powered
because the switch on the CPU Card is in the non-HFF position
• Switch off the power to the controller
• Move the switch on the CPU Card to its HFF position
• Switch on the power to the controller and ensure that the correct traffic signals flash as
the controller starts
There are various RJ45 connectors used to connect to peripheral cards within
the ST950 family of controllers. Most are not Ethernet ports and should not be
connected to other equipment, including PCs.
