Cannot get COM port when connecting to the switch

krugenator — Tue, 29 Nov 2022 01:09:12 GMT

My ICX 7150-C12P seems to be stuck in boot mode (amber system light). When I connect to the switch via port 15 I am not seeing a com port in my device manager. When I connect to port 13, I get a green light on my adapter and the switch port (so I know the cable and connections on both ends are good). I even tried using MobaXterm to get it to automatically recognize the COM port, but it is coming up empty.

I am on Windows 10 Pro. I turned off Windows defender to check to see if that was limiting the connectivity. What else do I need to check so that i can get the switch to boot, and/or do a software recovery?

Thanks in advance for your help.

Hey @krugenator

Are you a Lennar customer? Console port on your unit should be USB type C. It will not be one of the dataports.

Ben -

yes it is a Lennar unit. the instructions on the specify you can connect to port 1 (USB Type C) or port 15 ethernet depending on the cable you have (it also said if you have to do a software recovery that is done via port 13 which is just ethernet (RJ45 I guess)). I ordered a USB ethernet adapter for this.

I tried to connect my laptop USB type C (port on my laptop) to USB type C (switch) as well before ordering the cable but no luck. Is there a way to chat with someone to work through this?

Good morning, ok I got a USBC cable and was able to connect to the switch, When I entered the command "boot" I got the following.

boot

I assume this means I need to do a software recovery? Can you advise as to next steps? Thanks in advance for your help

Hi @krugenator

These cables in the guides are exclusive to access the console on the ICX-7150 C12P 'USB to USB type C' and 'Rj45 to USB', when using adapters we do not guarantee that this connection can be achieved.

I know some customers create a connection like this :

USBC cable -->female USBC to male USB3.1 --> female USB3.0 to male USBC.

But the most important part is to install the software so the PC or Workstation can read the cable correctly

Hi @krugenator

Correct basically the switch is stuck on boot mode you can follow up some steps and video links below .

1-Please try to disconnect from the Power outlet the ICX-7150 and reconnected.

2-Please try to press the reset button using a paper click or a small stick

Remove power from the switch.
Press and hold the Reset button while applying power to the switch.
After all the system LEDs flash amber, release the Reset button.

If that does not make any difference, we need to perform a software recovery since it can be that the image flash is corrupted so in basic words the unit is not able to boot up properly and need re-install the image to boot up properly.

3-Once we are there, we can try to boot up the unit using the following commands:

Boot_primary or Boot_secondary

If that step doesn't work, software recovery must be applied

Here is the guide to apply the software recovery correctly :

Hi Fernando -

Good news I have been able to establish connectivity between my laptop and the 7150 switch. I am attempting to do the software recovery. I have configured my ethernet adapter to be a static IP per the instructions (and verified via ipconfig). I have also set the env parameters on the switch and verified via printenv.

The challenge I face now is that i cannot ping my laptop from the switch. Are there reasons why it might not be able to ping? Here is the printenv from my 7150 switch. Please advise

ICX7150-Boot>printenv
baudrate=9600
ipaddr=192.168.0.3
serverip=192.168.0.2
netmask=255.255.255.0
gatewayip=192.168.0.1
uboot=mnz10115.bin
image_name=SPR08090d.bin
ver=10.1.15T225 (Jan 30 2019 - 23:08:47 -0800)

Hi @krugenator

Hope you are doing well !

Make sure the IP of the gateway and the IP of the server are the same as the IP address of the PC

Also make sure that is the IP address that you configured on the laptop is the IP 192.168.0.2 mask 255.255.255.0

https://pureinfotech.com/set-static-ip-address-windows-10/

If you can disable Firewalls on the laptop that may be preventing this ping

https://www.linksys.com/support-article?articleNum=143654

Make sure Ethernet is plugged into the management port on the ICX-7150 C12P to the laptop, or try any data port to see if it responds.

Note: To avoid any problems with Internet connectivity, try going offline while you are doing the software recovery.
