4.5 (Factory) configuration of the LD4NX ST card with Stocko
format
Figure 4-7: Top view of the LD4NX ST card
Two operating modes can be configured on the LD4NX ST card:
• LD4N operating mode: LD4N default configuration (operating mode compatible with the old
LD4).
• The LD4X operating mode, compatible only with software release 4.1 and later: The LD4X
operating mode is obtained by removing or adding jumper J14 of the LD4NX ST card in slot
1-2, and offers the following additional features:
• Since the LD4NX ST in LD4X mode uses the dedicated trunk of its slot, there are no
longer any restrictions on the location of the card.
• The card’s hardware information can be read through the MMC (presence of an
EEPROM on the LD4NX ST card in LD4X mode).
• It is possible to declare up to10 LD4NX ST cards in LD4X mode of a NeXspan L.
• It is possible to read the status of the S0 access of the LD4NX ST card in LD4X mode
remotely once the card is in service.
