I have a 6509 with sup720's and a ws-x6516-gbic module. The 6516 has been powered down since I started and today I tried to power it up but received the following error message
"%SYS-2-MOD_UPGRADEREQUIRED:Module 3 not at an appropriate hardware revision level to coexist with PFC3 system and current softw"
I've done some searches but can't find any information on what levels I need to be at or how to upgrade to get this to work. Any links or comments would be appreciated. Thanks.
