Do you know if you have the enhanced mid-plane? If not, it’s a chassis upgrade to install MPC3 or better line cards.
There is no need to upgrade the chassis even with old midplane. The worst you get is performance impact on MPC4/5E on SCBE2 or MPC10E on SCBE2/3. All MPCs will work on old midplane (some with reduced capacity) MPC7E and the already proposed 16 Port 10GE MPC (technically a quad MPC2 trio cramped into one card) work fine on the old mid-plane. You will loose support for some linecards when upgrading fabrics (e.g. no DPC from SCBE2 onward, and no MPC1/2E(non NG) from SCBE3 onward) If you only need some 10GE Ports you could just use the 16 Port 10GE Cards with the existing SCB and deactivate/use 8 of the ports. The cards are probably cheap enough on the second hand market to justify it. If you can get used SCBEs you can go up to 12 Ports (1+1 fabrics) or 16 Ports (2+0 fabrics) if memory serves well. For new cards cheapest per port price typically comes from MPC7E ... but overall costs depend on target number of 10GEs. Cooling/Filter and Power supplies will need upgrading as already mentioned from others. -- Kind Regards Tobias Heister _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
