There are two operating modes on the LD4NX ST card:

additionnal functions:
• the LD4NX ST card in LD4X mode uses the junction assigned to its slot, there are no
more restrictions concerning card installation rules,
• hardware information of the card can be displayed by MMC (an EEPROM is installed on
the LD4NX ST card in LD4X mode),
• you can declare up to 10 LD4NX ST cards in LD4X mode on a NeXspan L,
• the remote power supply status of LD4NX ST card S0 accesses in LD4X mode can be
displayed as soon as the card is in service.
