S4 Chassis returns a loop - " Waiting for chassis fabric to become operational."

[Weda]

I get below output recursively with newly installed S4 Chassis. There is only one switch module with the chassis.According to CLI output, image is loaded successfully. Then, "Waiting for chassis fabric to become operational." statement comes 20 times and reboots automatically. Any idea ??? < br>

Hi Curtis, This is our 1st experience with S chassis. Thanks for your advice .

You are welcome. Fabric module model numbers usually end with a F6 or F8 and are installed in slots 2 and 3 on a S4. The S3 does not require a fabric module.

That is an I/O module. You need at least one fabric module in a S4 Chassis.
