LS4 – link status of F/O port 4
(green LED)
– lit:
RH1-TP/FL receiving idle signals
from F/O segment,
– the F/O segment connected is
working properly
– flashes 2 times per period:
port has auto partitioned
– lit not: RH1-TP/FL not receiving any idle
signals from F/O segment,
– the assigned F/O port is not
connected,
– the equipment connected is
switched off,
– the F/O receiving fibre is inter-
rupted
LS5 – Link status of F/O port 5
(green LED)
Normal mode switched on
– lit:
RH1-TP/FL receiving idle signals
from F/O segment,
– the connected redundant F/O
segment is working properly
– flashes 2 times per period:
port has auto partitioned
– lit not: RH1-TP/FL not receiving any idle
signals from F/O segment,
– the assigned F/O port is not
connected,
– the equipment connected is
switched off,
– the F/O receiving fibre is inter-
rupted
1.5 CONTROLS
6-pin DIP switch
Using the 6-pin DIP switch on the top of the
RH1-TP/FL housing
– the message about the link statuses can
be suppressed by the indicator contact on
a port-by-port basis. Using switches LA1
to LA5, the message about the link status
of ports 1 to 5 is suppressed. State on deli-
very: switch position 1 (ON), i.e. message
not suppressed.
– port 5 can be switched to redundant
mode. State on delivery: switch position 0
(OFF), i.e. port 5 in normal mode.

TP connection
Three 8pole RJ45 sockets enable three inde-
pendent TP segments to be connected.
– Pin configuraion
of the RJ45 socket:
– TD+: Pin 3,
TD-: Pin 6
– RD+: Pin 1,
RD-: Pin 2
– remaining pins: not configured.

F/O connection
2 optical ports to 10BASE-FL (BFOC/2.5 (ST)
sockets) enable RH1-TP/FL equipment to be
cascaded as well as redundant rings to be
constructed using F/Os and terminal equip-
ment to be connected.
5-pin terminal block
The supply voltage and the indicator
contact are connected via a 5-pin terminal
block with screw locking mechanism.

Redundant mode switched on
– lit:
RH1-TP/FL receiving idle signals
from F/O segment,
– the connected redundant F/O
segment is working properly
and
is active,
– flashes 1 time per period:
RH1-TP/FL receiving idle signals
from F/O segment,
– the connected redundant F/O
segment is working properly
and is in stand-by mode,
– lit not: RH1-TP/FL not receiving any idle
signals from F/O segment,
– the assigned F/O port is not
connected,
– the equipment connected is
switched off,
– the F/O receiving fibre is inter-
rupted
IEC950/EN60950/VDE0805 may
therefore be connected to the
supply voltage connections and to
the indicator contact.

– Voltage supply
: The voltage supply can
be connected to be redundant. Both
inputs are decoupled. There is no load
distribution. With redundant supply, the
power pack supplies the RH1-TP/FL alone
with the higher output voltage. The
supply voltage is electrically isolated from
the housing.
– Indicator contact:
Contact interrupt
indicates the following by means of a
potential-free indicator contact (relay
contact, closed circuit):
– the failure of at least one of the two
supply voltages.
– a permanent fault in the hub for ISO/DIN
rail (internal 5 V DC voltage, supply vol-
tage 1 or 2 not in the permissible range).
– the faulty link status of at least one F/O
or TP port.
The indication of the link state might be
masked on a port-by-port basis using
DIP switches.
– at least one port has auto partitioned.
Port 5 in redundant mode doesn’t indi-
cate the state „auto partitioning“,
because this function characterizes the
error free state of the optical ring.
Note:
In the case of the voltage supply
being routed without redundancy, the RH1-
TP/FL indicates the failure of a supply volta-
ge. You can prevent this message by fee-
ding in the supply voltage through both
inputs.
