Hi All,

just looking for some help on connecting a ICX 7250 48P. I'm unable to connect to the serial port on the 7250. I'm using a prolific RS232 USB-A to DB9, then connecting from DB9 to Mini-USB. I'm on Win 10 and have PuTTY set up as per Fohdeesha's guide - Serial, 9600 N 1. Switch is connected to router via management port. All I'm getting in the console is random characters. Mashing B doesn't get me to any bootloader. The 2 cables I'm using are these. The UGREEN one has the prolific chip and I've verified it with Prolific's checker.

I've also tried using a Cisco USB to RJ45 cable, then slicing up a Mini-USB and using a Keystone jack to connect from the USB A - RJ45 - Mini-USB. Was following this guide. This method yields no response at all in the console. https://www.reddit.com/r/Brocade/comments/b71xtq . I previously used this cable to connect and set up a ICX 6430 48P back in 2021.

that can be an indication that the person/people before you tweaked the console baud rate.
At a guess I'd try 57600 or 115200 as likely choices. but you can always just step it. up till you find the correct speed (if that is what the issue is).

Yeah I tried other Baud rates-stepped through a bunch of the common ones listed and tweakedboth the PuTTY settings the device manager driver settings

Some baud rates spit out more characters, some less, but they're all the same characters. I did a bunch of rates -2400, 4800, 9600, 19200, 38400, 57600, 115200, 134400, 230400, 460800,921600

Hello all,

I thing I brake my ICX7250-48p switch, don't know what really happen :mad:
I was doing a fan mode on it two add two more sunon fan on the top of the case.
I've connected the two new fan to the fan1 and fan3 header, doing a parallel derivation on red/black wire.
Has it was not working correctly, I removed this two additional fans.

What happens now is that the switch is not starting when the 3 stock fan are connected to the switch : I just heard a tic-tic-tic sound coming from the switch.
Light are up front side, but just not booting up.

If I disconnect 1 of the 3 fan, the switch start, and boot correctly.
But after the boot, I can see strange behaviour.

- Fan are not switch to lower fan speed at end of boot up.
- Even if I change fan speed manually (dd set-frufan-speed 1), this have no effect, fan stay at full speed.
- A dm fan command show that fan1 speed is not detected correctly, even if it's running ok.
dm fan
Fan 1 Speed at 164 RPM.
Fan 2 Speed at 9060 RPM.
Fan 3 Speed at 9000 RPM.

Of course, I have checked header fan connection, and everything is ok.
I even try to swap the fan 2 to fan header 1, but same result.

I don't think there was a shortcircuit during the mods, can it be only that the total power consumption of the 5 fan was over what can be delivered by ICX7250-48-p, and so some chips goes wrong ?

I don't know what to verify from there, if someone as an idea for me, will be great !

Mashing B doesn't get me to any bootloader.
I got yesterday two 7150-24p and it didn't work on the first switch. After ten minutes I switched :)D) to the second switch where it worked instantly and I could setup the switch. Switched back to switch 1, restarted it and this time pressing b worked instantly.
You could try to let it run for 5minutes, restart it and then try pressing/mashing b

Just purchased a ICX6610 with 24 GE ports and 8 SFP/SFP+ ports, but only four of the 8 SFP ports are licensed. Is there still a way I can get a license to install and enable the other four SFP ports? I don't feel like dropping a few grand on EOL box if I can help it.

I've been happily running with my Brocade ICX7250 48P-2X10G switch for a few months now. Recently I observed my Proxmox cluster nodes regularly rebooting my VMs and I think I have traced the problem to the Brocade switch. It seems to reboot intermittently multiple times per day and I don't see an obvious pattern to it.

I have syslog remote logging to a server so these logs persist whilst the show logging outputs don't seem to survive a reboot. I don't see anything weird in there other than regular warnings along the lines of:

May 26 19:42:24:A:System: Stack unit 1 Temperature 67.0 C degrees,

I see this steadily rise to about 80C then at some stage a reboot occurs and the temperatures can be closer to 60C again then start rising.

I wonder then if these issues are actually thermal related despite being below the shutdown temperature of 105C? I also note that recently I discovered one of my ports with an SFP+ to 10GBaseT adapter was not blinking LEDs or providing a network. On replacing the adapter the switch quickly went into a boot loop with all amber LEDs. I had the system powered off overnight then next day it powered on ok with the adapter in except for this more intermittent boot looping.

Am hoping someone can make sense of this/have seen something similar in their own switch, and suggest how I can fix this. Any advice would be very much appreciated at this stage as aside from this new issue I have been very happy with this device. Thanks for your help!

Here is some further debug output:

Thanks for the suggestion! I was assuming the warning level of 0C meant I would get temperature warnings at any temperature, thus the logs showing increase from ~60 C to ~80C over time? If not, can you advise on how to set this warning level?

i am no expert, unfortunately for me but if we look at google:

source here

Code:
Changing the temperature warning level
Last UpdatedJul 24, 20171 minute read
RUCKUS ICX 7250FastIronFastIron 09.0.10FastIron 08.0.95FastIron 08.0.92FastIron 08.0.91FastIron 08.0.90FastIron 08.0.80FastIron 08.0.70FastIron 08.0.61+ 2
To change the temperature at which the device sends a syslog message and an SNMP trap, enter the temperature warning stack-id value command at the privileged EXEC level of the CLI.


device# temperature warning 1 82
The stack-id variable can be a value from 1 through 12.

The value variable is the temperature warning level, in Celsius. You cannot set this level higher than the maximum value allowed by your device. The temperature warning level must be at least five degrees Celsius less than the temperature shutdown level, which is automatically set by the device.

The following console and syslog message is displayed when the temperature reaches the warning level:

!!! Temperature is over warning level on stack unit 1!!!
imo the 0 means disable as most of other stuff so if you set it to 95 then you will have an hint if it is getting close to shutdown temperature.

cheers :p

Thanks! I increased to warning at 85 and my regular log entries stopped coming in, eg of the form:
May 26 19:42:24:A:System: Stack unit 1 Temperature 67.0 C degrees

So I blocked the fans to increase the temperature and the log messages returned above the 85C threshold. So I suspect the default 0C threshold was indeed just reporting any temperature.

In this test the highest temperature I saw was as indicated here:


show chassis


The stack unit 1 chassis info:





Power supply 1 (AC - PoE) present, status ok


Power supply 2 not present


Power supply 3 not present





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


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


Fan 3 ok, speed (auto): [[1]]<->2





Fan controlled temperature:


Rule 1/2 (MGMT THERMAL PLANE): 91.3 deg-C


Rule 2/2 (AIR OUTLET NEAR PSU): 40.5 deg-C





Fan speed switching temperature thresholds:


Rule 1/2 (MGMT THERMAL PLANE):


Speed 1: NM<-----> 95 deg-C


Speed 2: 85<----->105 deg-C (shutdown)


Rule 2/2 (AIR OUTLET NEAR PSU):


Speed 1: NM<-----> 41 deg-C


Speed 2: 34<----->105 deg-C (shutdown)





Fan 1 Air Flow Direction: Front to Back


Fan 2 Air Flow Direction: Front to Back


Fan 3 Air Flow Direction: Front to Back


Slot 1 Current Temperature: 91.3 deg-C (Sensor 1), 40.5 deg-C (Sensor 2)


Slot 2 Current Temperature: NA


Warning level.......: 85.0 deg-C


Shutdown level......: 105.0 deg-C



So maybe under heavy load the switch could be quickly overheating to the shutdown temperature before it has time to send a remote syslog message (highest I see in the logs is around 80C before it drops lower eg. 50C on next reboot)? But this seems unusual. Are there any other explanations/fixes people can think of? Thanks for your help!

Hello @All,

This quick post to talk about my ICX-7250-48-p fan mode.
I've find quite a lot of information on the forum about ICX 6650, but not a lot about ICX-7250.

You will find information about it at this URL:
GitHub - lo92fr/icx7250fanmod: A guide to Ruckus ICX7250-48-p fan mode.

It is now working for the last two days, and I'm quite happy with it : no more sound, and stable temperature around 50°C.
Documentation is not fully end, but I hope it will help other users !

Laurent.

hi,

i saw some good price on a 7250. is it still a good buy if i switch my 6450 for it?
only thing that stop me a bit is the power consumption difference: 25w vs 48w.

any though ?
