Verifying Fabric Cabling Connections
The following description helps explain the states of LEDs on the OIM LED panel. In
cables should connect an LCC S13 card to the FCC S2 card as follows: A0 to J0, A1 to J1, and A2 to J2.
Instead, A1 is incorrectly connected to J2. This incorrect connection causes the LED corresponding to
J2 to blink red, indicating that the cable connection is incorrect. The LED corresponding to J1 blinks
green to show where the misplaced cable should be connected.
