Is there anyone who can give more details about the enhanced midplane? >
It's just more lines (wires) to provide more fabric bandwidth per-slot/PFE. And maybe more power as well, I am not sure though. It's been shipping for ages (since 2012 or something like). It had been supposed to be required even for SCBE and MPC3 non-NG but then Juniper thought twice and finally it was not really necessarily until MPC5. See Sebastian's comment for what it it gives in terms of bandwidth per slot. So, in theory, all MX240/480/960 have been shipped with enhanced midplane for many years, if only your partner/SE, or whoever makes the specs, does his job well or you don't specifically ask for the non-enhanced version for some reason (if it's still not EOL, I don't remember). You can check whether you have it with the following command: user@mx480> show chassis hardware | match Midplane Midplane REV 04 750-047862 XXXX1111 Enhanced MX480 Midplane In the specs this is referred as MX480-BASE3 or -PREMIUM3 in contrast to -BASE or -PREMIUM for non-enhanced midplane. You normally don't buy a chassis on its own, so you don't see part codes like CHAS-BP3-MX480-S in your BOMs. AFAIR, you can also buy the new midplane as an FRU and change it yourself though it requires to get all the cards out of the box. -- Pavel _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
