Red Light in C4503 Chassis

[kshong]

Hello Everyone,

I am using Catalyst 4503 Chassis with WS-X4748-RJ45-E(10/100/1000 Linecard).

In bottom of linecard, I could see a red light.

Does anyone know what the red light means?

Thank you.

anything showing in logs for the line card ? have you tried to run a diagnostic on the actual card to see if its ok ?
any alerts when you check the command show module ?
