Cisco switch

I have a Cisco 300 series switch with the option to turn off the port LEDs via the switch management. Never tried it, as the switch is shut in a cupboard where I don’t notice it, but the option is there. 

Or just put a piece of insulation tape over the led.

Was just thinking this the other night, between the Cisco and the TP Link converers its like a bloody disco.

Put on some better music......that’s what I do.....take me to the gig

You must also have the mirror ball option activated

Sorry been looking for my whistle, did not find it ???? so will have to be black tape.

Just picked up a used 2960 a few weeks back... it makes no sense but it's so much better...I actually enjoy listening now.... before I was 99% LP

It’s almost a bit annoying.......but the 2960 really makes a difference, many thanks to those on the forum who padded on their wisdom.

Well, I’ve just ordered one ...

Yes it does, and not in the hi-fi sense. music just flows better and is more enjoyable...I think it was Huge who first recommended it. Many great people on here I have learned alot.

I have found most Catalyst switches seem to make a difference. When I first posted my findings of the 2960 on the forum a couple years back it was the 2960 I described. However the 3560, a catalyst layer 3 switch with PoE options has a similar positive effect and is what I currently use to connec to my streamer. Again these are available used at almost throw away prices on the usual auction sites.

◾ Have you the same SQ from the 3560 or maybe better than the 2960?

◾ Is it,like the 2960 "plug and play" or must you do some more advanced installations.

◾ Can you give us the exact modelnumber for the 3560 you have.

We are alot of people here in Sweden, who use this 2960 because of your recommendation......THANK YOU! I know this because I have a High End-forum here....and we have followed your advice here on this fantastic Naim-forum.....again, THANK YOU.

Simon-in-Suffolk...hey  ,don't forget my 3 questions right up here if you have time.

We shall order up to 15 Cisco 2960 for the third time,we do this at our forum for members. We have found a company that only works with preloved Cisco equipment,they also test every Cisco in a 26-steps testprogram. So we know that every Cisco is up to date.

Some has failed in this testprogram,before we buy'd from this company, we take Cisco's from "the bay". Two times with Cisco's from "the bay",there have been lower soundquality from one Cisco. So it is more save to buy from this company we think,....if we talk about soundquality.

Before we order again,it would be good to know if we shall go for the 2960,or maybe the 3560 that you talk about.

Over to you,..../Peder

Just got a WS-C2960-48TC-L today. It won't play with my Arcam rPlay though. Youview box/Netflix works fine.

Logged onto the switch bit it doesn't understand "flash_init" or "boot"

See below output.

Any ideas? Do I need to get on via console instead of telnet?

Get a 3560 from an online site says Simon so I did, wish I’d listerend earlier! arrived today plug it in and worked perfectly. How did sound, just cleaner. Thanks Simon

Great Richard,nice to hear about your higher SQ .I asked Simon about the modelnr for the 3560, because the WS-C2960-8TC-L  is different against WS-C2960-8TC-S. The WS-C2960-8TC-L (the right switch) is stronger.

I have read that on this forum,because of that,when we shall order up to 15 Cisco's on our forum......we will order the right Cisco's. And Simon talk about his 3560,we will of course have the right modelnr before we order this 15 Cisco's for our members.

I have asked 3 question a bit up here in this thread,I hope I can have some answer before we order this 15 Cisco's.

Hi Peder,

I did a lot of testing on this a year or two ago. I used three models of switch, all Cisco Catalyst’s. The WS-C2960L-8PS-LL, the WS-C3560-8PC-S (v01) and what I'm currently using a WS-C3560CX-12PC-S.

I tested with power-over-ethernet on and off on the switch, with various different software versions and with various configs loaded on the switch. The software versions were all within the 15 major release train including IP Base and IP Services variants. I did not regression test with very old images and this could be where the difference you are hearing is coming from.

I could hear no difference between switches and configurations but could hear a similar difference between and three models and the previous NetGear switch.

S-in-S posted around the time that he had a theory it was due to the circuitry in the Catalyst switches and how they ensured accurate timing of packet delivery. My testing would appear to confirm that. I wouldn't worry too much about the specific varient of Catalsyt switch, except for keeping to the compact versions which don't have a fan.

So any Catalyst switch, unless you know better keep it simple and don’t bother with any config, but if you do config it that does not appear to impact audio quality. For simplicity’s sake I would avoid multiple VLANs in a domestic environment if you are tempted but that route. Needless complexity.

I didn’t test VLANs in my testing for the above reason and if you do need PoE I’d configure it as far away as possible from the streaming ports. So in my scenario I have NAS and audio kit on the lower numbered ports and the wireless access point which draws PoE on the highest numbered port. The Ethernet cables are routed separately just to ensure no noise contamination between cables.

 Hope this helps,

Russ

1. Can’t tell any difference between the 2960 and 3560. They are both Catalyst switches if that is relevant.

2. Yes from factory default, the switch will function like an un managed switch and be a plug and play standard layer 2 switch.

3. Cisco WS-C3560-8PC (PowerPC405) processor (revision A0) with 131072K bytes of memory.

@Simon-in-Suffolk, did you get my message?

Richard... i have now found your message.. it was in my junk mail folder!  I will respond off forum.

Simon

That’s what I feared, hence my post here. Best, R

I don't suppose anyone knows if some of the other Cisco models are equally beneficial? The Cisco SF 110D 8 Port, seems to be readily available where I live but it is harder to come by 2960s that aren't the 24 or 48 port versions.

First thing is if you do go for the baby Cisco,  be sure its the SG110D,    the SF is 'fast' 10/100 Mb/s   the SG is 'Gigibit'  10/100/1000 Mb/s.          I have the SG110D to replace a Netgear GS105;  I'm not getting into sound better claims, but it does something different in my system compared to the Netgear & I'm not talking only about SQ,

I bought mine from UsedCisco in Germany for 50€ plus  carriage in Europe at 10€. Very pleased as it was refurbished and tested. No bidding needed. I suspect that Peder and his Scandinavian group buy from them. Nothing in your profile to indicate what part of world you come from.
