As far as I'm aware, only the Supervisor card is covered under Cisco Limited Lifetime Warranty. 

But be careful when using LLW as it is to Cisco's benefit to "deny" anyone from claiming LLW.  You have to know what the LLW T&C or you will be duped.  I have very good experience with RMA-ing parts and appliances based on LLW and there are certain times when TAC engineer will somehow "forget" about LLW.  This is even more true when Cisco legal team has made changes to ELLW/LLW T&C.  Know your rights well.
