LINK MODES
These four DIP-switches configure the different link modes available on the XG. It is
recommended to have link modes set to Link Segment (default setting - all DOWN)
during the initial installation. After the circuit has been tested and operational,
configure the module for the desired mode.
For detailed information on the operation of the different Link Modes, download the
application note “iConverter Link Modes” available at:
https://www.omnitron-systems.com/documentation/
* SFD requires bookend configuration of two iConverter XGs connected via Port 1.
SELF DIAGNOSTIC CIRCUIT TEST (
SFP+ models only
)
The self-diagnostic circuit test on the 8599-0x and 8599N-0x are not compatible
with the self-diagnostic circuit test on the 8599P-0x and 8599R-0x.
When two XG 8599P or XG+ 8599R converters are connected via Port 1 (Port 1 to
Port 1), a self diagnostic circuit test is supported. To initiate a self diagnostic circuit
test, both the local and remote module must be configured.
Configure the DIP-switches on the remote module for “Self Diagnostic Circuit Test
for Remote Module” (DOWN, DOWN, UP, UP).
Configure the DIP-switches on the local modules for “Self Diagnostic Circuit Test
for Local Module” (UP, UP, UP, UP).
The local XG will initiate the circuit test (all DIP-switches to UP) by generating and
sending a test pattern out Port 1 to the remote XG. Once remote XG detects a
good test pattern, the remote XG will return the test pattern back to the local XG.
No data is transmitted on Port 2 of either module when the self diagnostic circuit
test is enabled.

DIP-switch BANK 1 Definitions
The XG supports port loopback. The SFP+/SFP+ XG supports loopback on each
individual port or simultaneous loopback on Port 1 and Port 2. The SFP+/XFP and
the XFP/XFP XG supports loopback on each individual port and does not support
simultaneous loopback.
In all cases, both transceivers must be installed in the XG for the loopback
feature to operate.
SW1 - P1 LOOPBACK “P1-LB”
When this DIP-switch is in the LEFT/DOWN position (factory default), Port 1 (P1)
loopback is disabled. When this DIP-switch is in the RIGHT/UP “P1-LP” position,
loopback is enabled on P1. When enabled, all data received on P1 is transmitted
out P1 and all data received on Port 2 (P2) is dropped. No data is transmitted on
P2 when loopback is enabled on P1.
For XFP models, the loopback feature is dependent on the capability of the
installed XFP. XFPs with XFI-side Loopback feature are required.
SW2 - P2 LOOPBACK “P2-LB”
When this DIP-switch is in the LEFT/DOWN position (factory default), P2 loopback
is disabled. When this DIP-switch is in the RIGHT/UP “P2-LP” position, loopback
is enabled on P2. When enabled, all data received on P2 is transmitted out P2 and
all data received on P1 is dropped. No data is transmitted on P1 when loopback
is enabled on P2.
For XFP models, the loopback feature is dependent on the capability of the
installed XFP. XFPs with XFI-side Loopback feature are required.
