The SAM600 modules contain several LEDs to indicate the current operation
states. The main SAM600 module indication LEDs are located on the front side
(see

There are 4/8 more LEDs on the sides that indicate the network activity and link
state of the optical transceivers. For SAM600-CT and SAM600-VT modules (see
Figure 23) , there are 4 LEDs for the optical transceivers link state and there are 8
LEDs for SAM600-TS (see Figure 24) .
