I have a 3640 that is giving me the following message when it is booted:
No fault history 0xffffffff. Need 11.1 (2) or higher ROM.
Slot1 will then come up as disabled. The cards in the 3 other slots work fine. The ROM version that is running is 11.1(20)AA2, which seems to be a higher ROM than is needed. I am using NM-2E2W cards, and I have tried NM-1FE2W cards. The error message is the same, and the cards in slot1 will not work. The LED's on the cards in slot1 come on during bootup, but the enable light goes out once the router has finished booting. Do I have a bad slot, or do I need a new ROM chip? Please advice. Thanks.
