 Configure FEC card
 --------------------
-For the Bronze Release only a SW FEC is available so this step is not needed, for later releases the required information will be added to the document.
+For the E Maintenance Release either a SW FEC, or an FPGA FEC (Vista Creek N3000) or an ASIC FEC (Mount Bryce ACC100) can be used.
+The procedure to configure the HW based FECs is explained below.
