Description of the switches
Micro-switch CA1 (HVAL) is used to configure synchronisation (T0).
Case of LD4N in T0 configuration (shelf 0 of the main cabinet only)
Jumpers J1_1, J1_2, J1_3 and J1_4 are used to enable the remote power supply (40 V or 48V)
of each interface where an S0 interface is connected.
Caution:In T0, remove the jumpers (conflict between the 48V supplied by the system and the
40 V supplied by the public exchange)..
Note: J2_1, J2_2, J2_3 and J2_4 are storage positions for jumpers.
Jumper J14 is used to select the LD4N card's operating mode: plug it into pins 2 and 3 =
mandatory position (whether a jumper is plugged into pins 1 and 2 or not, the LD4N card is
configured with implementation of additional functions reserved for future use).
Jumper positioned on SW5 or SW6 is used to select the 40V or 48V remote power supply.
Jumper positioned on SW5 (factory position) is used to select the 48V power supply.
Jumper positioned on SW6 is used to select the 40V power supply.
Note: The LD4N card has no microswitch for downloading the flash memory with a BOF3 type
tool (automatic detection).
