If your SLC is running 6.1.x firmware on both banks you can directly load v6.3.0.0 using the following links. If only one bank has 6.1.0.0 or higher installed, and it is the "current" bank, you will need to reboot to the other bank so that you are upgrading the 6.x bank. You can do this on the Maintenance>Firmware/Config page. Attempting to load 6.3.0.0 into a bank with 5.x firmware will fail.
