3.10.3 LED Observations
3.10.3.1 Power On
At initial power on, PWR LED will not be lit. If active LAN is connected to the TP port, that Link and Speed LED will be lit. After 25 seconds
the CPU has fully booted, PWR LED will be lit.
Error conditions:
If all LEDs immediately light and never turn off, or if no LED ever lights, then the unit is possibly defective. Be sure to double check power
source.
3.10.3.2 UTP Link Test
Following a complete power and boot up (about 25 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.
3.10.3.3 Fiber Link Test
Following a complete power and boot up (about 25 seconds) the converter will be active. For FTH4-1000MS , 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. For
FTH4-1000M & FTH4-100M , use a simplex patch cable (single fiber strand, SC to SC, ST to ST or FC to
FC), route the Tx back to the Rx optical connection. The FX LNK LED should light.
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.
