3.3.2.2 UTP Link Test.
Following a complete power and boot up (about 15 seconds) the converter will be active and LAN port will display LAN LNK state when
connected to a live Ethernet circuit. The LAN SPD LED will be green when connected to Fast Ethernet (100M) and yellow when connected to
Gigabit Ethernet (1000M). When connected to 10Base-T the LAN SPD LED will be off. If there are no link indications for a live connection to
LAN, check if LFTP is enabled in the configuration. When LFTP is enabled, there must be both live Fiber and LAN connection.
3.3.2.3 Fiber Link Test
Following a complete power and boot up (about 15 seconds) the converter will be active. For FMC-2000MS, place a known good SFP module
into Fiber Port cage. Use a simplex patch cable (single fiber strand, LC to LC), route the SFP Tx back to the Rx optical connection. The FX LNK
LED should light. If there are no link indications for a live connection to Fiber, check if LFTP is enabled in the configuration. When LFTP is
enabled, there must be both live Fiber and LAN connection
Caution: When performing a physical loop back on any fiber port, DO NOT connect the LAN port to a live Ethernet network. Doing so could
create a broadcast storm.
3.3.3 Operation Checks
3.3.3.1 Converter Check
A very easy way to ensure a pair of FMC-2000MS is passing traffic, is to place them between two PCs. Connect PC1 to LAN of one converter
and PC2 to LAN of the other converter. When the two PCs can ping each other, it indicates FMC-2000MS pair is operational.
3.3.3.2 Ping Test
With FMC-2000MS reset to factory default, connect a PC and configure the PC to the 10.1.1.0 network (10.1.1.100 recommended). Use a
PC to ping FMC-2000MS at its factory default IP address of 10.1.1.1. With a direct connection to PC, there should be no time outs and ping
latency should be less than 1 millisecond. If you switch to another FMC-2000MS, be sure to clear the PC ARP table. Every FMC-2000MS has
the same default IP address, but every unit has a different MAC address. To clear the PC’s MAC table, open a command window and execute
the command ‘arp –d’. In addition, if you disconnect the PC from any LAN connection and then re-connect, the ARP table should also be cleared.
