Re: [j-nsp] M20 SSB E Memory seller required
You will need the 128MB DRAM upgrade if you have lots of routes as well as a couple of thousand of arp entrys. This will fill the memory on the SSB-E very fast and once you hit the 64MB limit the router will do weird things (e.g. several ip address no longer reachable, routes not being installed etc). Some time ago i had posted regarding this on the list...if you are interessted just search the archive. We do still run some M20's and we upgraded all of them to 128MB (except those running SSB-E-16 of course). However their days are counted.

I thought this might be worth mentioning, as the platform is certainly dated. If you have enough routes in PFE that you need the SSB-E-16, your control-plane is probably not very fast. -- Jeff S Wheeler Sr Network Operator / Innovative Network Concepts ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
Re: [j-nsp] M20 SSB E Memory seller required
You can upgrade SSB-E to 128MB with http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=64M-EDO-DIMM-ECC (as per juniper.cluepon.net) The SSB-E-16 has 256MB of RAM by default... I'm not sure if upgrading the DRAM does anything useful or not as Juniper never intended for the SSB-E to have anything other than 64MB DRAM. The 8MB of SRAM on the SSB-E limits it to 550k active routes (l3, l2) so the SSB-E-16 may be a more useful upgrade than 128MB of DRAM. (Of course if I installed an M20 with an SSB-E, i'd put 128MB of DRAM in it just on principle) Martin T [m4rtn...@gmail.com] wrote: > I have one M20 SSB-E(710-001951) which uses SMS SM57208809WDTX6 64MB > SDRAM DIMM.

Re: [j-nsp] M20 SSB E Memory seller required
I have one M20 SSB-E(710-001951) which uses SMS SM57208809WDTX6 64MB SDRAM DIMM. It uses Samsung K4E6408120-TL50 memory chips. Maybe this information helps if you should accidentally find a SM57208809WDTX6 from second-hand market. regards, martin 2011/8/10 Juan C.
