The LS5D00E4GF01 subcard can only be used on an S5300EI, and the LS5D0E4GFA00 subcard can only be used on an S5300SI. If the LS5D00E4GF01 subcard is installed on an S5300SI or the LS5D0E4GFA00 subcard is installed on an S5300EI, the subcard cannot register.
The LS5D00E4GF01/LS5D0E4GFA00 front subcard must be used with an ES5D00ETPB00 extended rear subcard; otherwise, only the first two interfaces on the LS5D00E4GF01/LS5D0E4GFA00 subcard can work.
