Most likely, yes. Though the 6148s are 'classic bus' cards, which do not
use the chassis fabric. They're hideous and slow down the whole router,
due to taking up bandwidth on the classic bus that is also used for
lookup signalling between CFCs and the supervisor (no use of classic bus
cards, and the use of DFCs, is required to overcome those limitations).

If you're intending to add more, please add 6548s as a minimum. Better
yet, please put all of your 7600 gear into the sea and use more
power-efficient devices. :)
