Well, weird enough, specifying 'lacp-timeout short' the lag actually stays up.
I'll now run the entire deployment process and report back. Maybe somebody else ran into the same issue
Somehow the issue was related to the lack of timeout. Probably the unspecified default results in some timing issue if for "too long" LACP doesn't go up. Thanks guys!

odd question, did you happen to dust the thing out previously by blowing canned air into the fan trays?
I opened it up to see if there was anything obvious (dust, parts visible from the top, etc.) - switch was clean as a whistle. I don't feel confident enough to disassmble the switch entirely to get the motherboard out and look for a cold solder joint or broken trace on the motherboard.

During the time the switch was off, at one point it did drop about 3 feet from the shelf it was on to the concrete floor. I expect that something's physically damaged. Sigh. As I said, I have a ICX 7250 on order.

Thanks for the ideas, folks.

Well... yea.. that was really no bueno for sure.
OUCH. rest in peace 6610
Indeed.
Buut... broken it is... so... you can actually open it and try to look at dislodged components or broken traces/board without fear of breaking it... I mean... :D

I searched online, found GDSTIME Quiet 80mm Fan, 12V 3PIN 80mm x 80mm x 10mm Brushless DC Fan for CPU Coolers , put on top of the chip heat sink and it fits perfectly.
Do you mind posting some more pics / details on how you did this? I've got a 6450-48 swapped with a Sunon that is running super hot even with the fan on high. Under the original stock fan it would switch to low speed at boot but with the new fan it stays on high at all times and is fairly loud.

Already put the switch on my rack. Will see if I can take it out and take some more close up picture.
Here is some picture I took before I put it on rack.

1590677357296.png

My switch is ICX7240-48, NON-POE version, so there is some space between the main chip heat sink and the top shelf. I measured about 15MM

The 10MM fit into that space perfectly. I just use some drywall screw to fix the fan on the heat sink.
1590676923992.png
This screw is too long. You can by some short one. I just cut it short.

It is still not cool. But it is stablized at 77C. Below the temperature threshold (98C) of Speed 2 so it won't ask the fan to run at full speed which is noisy.

If you want really good cooling, you can cut a hole on the top shelf and install 120MM fan. or like this to cool off a POE switch. It is very quiet and temperature is very good.

You'll have to verify that it is not used at the moment (ie. no DHCP lease active), and it is outside of the DHCP pool ;)
Reviving page 124 from November. I'm a newbie+ on networking and CLI. If anyone has problems figuring out the config part of, "Now we need to assign that virtual interface an address. Choose an IP that is unused in your subnet, and out of your DHCP server range (ping it first to be sure it's unused)"

I use 192.168.0.1 for my main network. I used an old asus router that uses 192.168.1.1 in order to config my switch. Fohdeesha's doc made sense because he uses 192.168.1.1.

Once I put the switch on my network, I assigned it a static 192.168.0.xxx on my router, and then had to redo the command on the CLI to change the ip to the xxx I chose. (the interface ve 1 | ip address 192.168.0.xxx/24 commands)

My only other question is that the uplink ports "don't support half-duplex". Why does this matter, why would I want half-duplex? If I connect sfp+ connections (either directly to a nic or to a stack), the rj45 uplinks still function full speed, right? Some prosumer switches allow the sfp+ or the sister rj45's to be used, but not both at the same time.

My OCD may end up cleaning this thread up..., or creating a wiki like I did with the HP N40L (multi-hundred pages on an Australian forum, STH and homeservershow, and then Hardforum got confusing). So much good information/discussion here scattered amongst 180+ pages.

Thanks to all who have contributed to this thread, and to Fohdeesha

Hi all, new forum user here,

I've read through this thread a few months ago, and just searched it for further info on my question, so I hope that my questions isn't too much of a repeat of previous ones and that this is indeed the appropriate place to ask.

I'm looking for a new main switch for my home network and I'm ready to dip my toes into the sea of enterprise-grade equipment (or at least something close to it) and am currently contemplating either the ICX 7150-24 or the ICX 7150-C12P for that role.

Background: I already run 10G on my NAS and my PC and have a MikroTik CRS305 switch to connect both and use the 1G uplink to connect to my router. As a router I'm currently running Untangle on a Protectli FWB6 Mini PC and the rest of my gear is repurposed consumer-grade equipment (including old Wifi routers running in AP mode).

The goal for that new switch would be to be to act as the main switch with the following requirements:
* 10G downlink to my MikroTik switch
* Provide extra SFP+ ports for future 10G devices (optinality)
* Provide 12+ 1G RJ45 ports for my networking equipment
* Be silent or near-silent (since the switch will be located in my office, near to my desk)
* PoE is nice to have, but I don't really need it right not (optionality)

At a later point I'm planning to retire the current APs and go with something more solid.

It seems that the ICX 7150-C12P and the ICX 7150-24 (non "P") would both fit the bill. Unfortunately the ICX 714024P (edit: I mean of course the 7150-24P) would not, since - according to the data sheet - it has a minimum noise level of 41.4 dbA, which appears to be too loud for my use case.

The prices of the 7150-C12P and the 7150-24 on eBay's US-site are in a pretty similar range. I like the optionality of PoE, but I like the optionality of more SFP+ ports quite a bit more. I don't really need 24 RJ45 ports, the 12 ports of the -C12P would be fine, it's just the exta SFP+ ports and the similar price range to the -C12P that make me lean towards the -24 model.

Before I pull the plug (or push the "Buy" button) I'd like to ask the following: Does the 7150-C12P have any advantage over the 7150-24 other than the smaller form factor and PoE or would (at it appears to me right now) the 7150-24 be the better choice for my use-case?

Thanks in advance for any advice on this matter.

Oh for $santa sake, please don't... Those boxes are very well engineered, don't ruin countless hours of airflow engineering for a redneck solution.. simply put, if the replacement fans can't keep the unit cool enough, they can't move enough air.. Instead of cutting holes on the top and disturbing the flows with random fans, all @noise850 has to do is to replace the replacement fans with others slightly more powerful.. and maybe it won't be any louder because they will actually be moving the air through the unit, instead of stalling and choking due to insufficient static pressure. ;)

I am not sure what you mean with "half duplex"... SFP/SFP+ ports can't negotiate 100Mbps or lower, so there isn't any specification for a gigabit speed (or higher) with half duplex connection.
What you might wanted to say was "dual personality" or "dual media" ports... if that's the case no, there is no dual media ports.. every interface has it's own physical connection and all can be used at the same time.

Generally speaking, the "C" model doesn't have any advantages other than being passively cooled, smaller in size and possibly reverse-PoE powered from the upstream port.
Other than that it's pretty much the same as the non-C version, but keep in mind that the compact tend to run fairly hotter than the rack version.

i think that you can also swap the fans on the 7250 with other models, but don't count on my word for it, have a look at the thread if this is what fulfils your needs.

Agree with you on the airflow engineering part. It is definitely very sophisticated. But it is designed for data center. Noise is not an issue, density matters. For folks want to us at home, noise is a major issue. Like me, many people put the gear in their living space. 40dBA is probably the max noise level while in Data center, 70+dBA is common. Physical law determines that smaller fan will generate higher noise. I have tried numerous 40mm fan including Noctua, I haven't found one that has good air flow yet silent yet.

Thanks so much for responding. Actually the data sheet seems to say that the 7150-24 (not the 7250-24!) is also passively cooled or did I misread that?

Yes, according to the datasheet it's fanless. Even the 7150-48 doesn't have a fan.

The 7150-C12P is not PoE powered, and it only has 2 SFP+ ports, the only ports on it that can do 10G. There are 12 PoE ports, then 2 non-PoE gigabit ports, and the 2 SFP+ ports.

If you need more than 2 10G ports, the 7150-24, or a 7250 would be decent choices, or the 6610. A 7250-24 or a 6610 would give you 8 SFP+ ports, the 6610 also has 4 QSFP+ ports and I believe that 2 of them support 4x10G breakout.

Yea, sorry, I was thinking at the 6450-C12-PD which can act as a PoE powered device.

Sorry I've missed your post before. You are right about the noise, but those aren't datacenter grade switches (trust me, you don't want to stand next to a Cisco 9300 series units at startup; at full tilt those screams at 100dB or thereabout), but access grade switches, they are ment to be installed in some networking racks/closet near the offices.
I've seen a video about a fan swapping of a 6450 with some noctuas and it became basically inaudible at 30% PWM... But yea, you need to find the right fans capable of moving air through the unit.
Don't expect it to be at 30°C/90F, those are older process silicon, they are designed to run at 50-60°C/120-140F basically all the time, and hardly ever be shut down. ;)

Do you mind taking a look at my post on the previous page about my temps? The office it is in tends to run hot in the evening and the temps on the 6450 seem to be really hot for me. I tried both types of Sunon fans that have been mentioned here and both perform about the same (considering they both have about the same spec cfm). The switch always keeps the fan in high mode and it is much louder than any other system in the room. In high mode the Sunons are definitely putting out a decent amount of air and holding your hand up to it the air is pretty dang hot.

I'd be willing to try any fans you or anyone else may recommend, I just need to find a good balance of temps to noise.

Sorry I've missed it but I haven't seen any temperatures in your messages.
6450 should turn the fans to low shortly after booting, but it doesn't have a standard pinout compared to the one used on PCs.
At boot, the thermal inertia of the heatsinks should provide low fan speed even in the hottest of the human-populated rooms, and it could run in pretty much safe temperatures even without any fans at all (not that you should!).
Probably, you problem is not temperature related, but simply the fans aren't spinning down as they should... try issuing a show chassis and look after the temperatures and "requested" fan speed level.

Can someone help my stupidity, this is my first CLI switch. I am following Fodeesha's guide on updating the firmware and when I am trying to set the access protection for username and password I have gone:

Enable
Configure terminal
User Root Password Mypassword

I get "incomplete command" I assume I'm just missing a pre-heading and I think it's supposed to be:
enable super-user-password mypassword

Am I doing something wrong here?

Edit: password cannot begin with a number. :rolleyes:

Code:
Power supply 1 (NA - AC - Regular) present, status ok
Power supply 2 not present

Fan ok, speed (auto): [[1]]<->2

Fan speed switching temperature thresholds:
        1 -> 2 @ 69 deg-C
        1 <- 2 @ 64 deg-C

Sensor B Temperature Readings:
        Current temperature : 51.0 deg-C
Sensor A Temperature Readings:
        Current temperature : 62.5 deg-C
        Warning level.......: 66.0 deg-C
        Shutdown level......: 76.0 deg-C
These are the current temps. Although when I posted previously I saw temps hitting 66-67 on Sensor A and it never logged a warning.

The fan speed shows it should be in speed 1, but it clearly isn't as the fan never spins down. It runs at the same speed after a fresh reload as it would if I manually set it with dd set_pwrfan_high. The only time I can get it to run at a low speed is with dd set_pwrfan_low, at which point the temps climb so high I get nervous and either put it back to high or reload the switch, in which case it sets it back to high again.

Current fan I have in it is a Sunon MB40201V3-000U-G99. I also tried a Sunon KDE1204PKV3 before that, which reported as fan failed so I swapped for the MB40201.
