3.3.2 LED Observations

3.3.2.1PowerOn

At initial power on, PWR LED will be lit.

Error conditions :

If all LEDs immediately light and never turn off, or if no LED ever lights, then the card is possibly defective. Be sure to double check power

source and try either another FRM220-1000MS in the same chassis or try the card in a different chassis.

3.3.2.2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.

3.3.2.3FiberLinkTest

Following a complete power and boot up (about 25 seconds) the converter will be active. For FRM220-1000MS, 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 FRM220-1000M, 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.

3.3.3 Operation Checks

3.3.3.1ConverterCheck

A very easy way to ensure a pair of FRM220-1000MS 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 FRM220-1000MS pair is operational.
