Cisco 9400-Supervisor Engine 1XL uplink help

Question

I have inherited a Cisco 9400 with 6 line cards installed. I am trying to use some ports on one of the cards. I noticed that there is no link activity lights, no indication of any activity.

I think this has something to do with the Supervisor engine. I looked up the documentation here https://www.router-switch.com/media/upload/product-pdf/cisco-catalyst-9400-series-supervisor-engine-1xl-datasheet.pdf

And noticed that there are several options for "uplink" ports. I think this card is currently configured to support 4x10GbE, and 1x40GbE. I have no use for the 1x40GbE port, and would like to "turn on" the remaining 4x10GbE instead, giving me 8 of them.

I hope this helps, I do not know how to interpret it:

Answer 1

With dual supervisors installed, you can only use the first four interfaces on the supervisors. You are limited to eight supervisor interfaces, either on one supervisor, or split between the two supervisors in a dual supervisor switch.

That is because only one supervisor is active at a time, and it can only control eight interfaces: four on each supervisor.

With only one supervisor, you can use the first four interfaces, and either the next four or the 40 Gb interface, but not both.
