That's true for MSC and MSC-B. They are virtually the same, but the B-version draws less power (and requires a newer XR-version). > The only downside to FP40 that I have found so far relates > to the inability to use SIP-800 (and as a results, older SPAs). The FP40 is a completely different breed, and as you have found out, supports different PLIMS than MSC/MSC-B. These linecards where originally designed for the ASR14k (a CRS1-light device), but it were pulled from the market before getting released (more or less). The downsides of FP40, compared to MSC/MSC-B, are less hardware queues and not being able to do 40G at minimal packet sizes. You can use older SPA's in any of the "Flexible Interface Modules" (http://www.cisco.com/en/US/prod/collateral/routers/ps5763/data_sheet_c78-553671.html and http://www.cisco.com/en/US/prod/collateral/routers/ps5763/data_sheet_c78-549654.html). -- Pelle _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
