GS752TPv3 with firmware version 6.2.0.36 - ports 1-24 no lights, but ports function
Hi All,
We have a strange occurance at a customer. NetGear GS752TPv3 with no active lights on ports 1 to 24, although the ports are active and functioning properly.
This is the second time that this is happening at the same customer. This is, in fact, a replacement unit.
The first switch we had, had the same symptoms, not lights on ports 1 to 24, but in addition to that it also seemed that DHCP (broadcast traffic) did not work on ports 1 to 24. In that case, we have temporarily moved all the devices to the free ports 25 to 48, and they started to work, while we waited for the replacement unit. We had no issues with all the devices connected to ports 25 to 48. The switch was replaced a week later.
The replacement unit was configured, by hand (not importing the config) and it was working well since then. (this was just over a month ago). This morning we noticed that on the replacement switch, the lights 1 to 24 are not on. Despite this, these ports are functioning normal. We did, however, restart the switch and ports 1 to 24 lit up again.
On both switches (the original and the replacement) we had / have the latest firmware running (version 6.2.0.36).
I do not see any errors on the ports, or in the config, unless I am not looking in the correct place.
Is this a known issue on this model with this version of the firmware?
Since only 1-24 are link and activity LEDs are affected and the switch is operational, a clear indication of a hardware issue. Head to https://my.netger.com/ and select the switch serial number affected, and follow the [Request Hardwre Support] process on behalf of your customer.
As the GS752TPv3 isn't a Manged Switch, I'll suggest a moderator to move this thread to the more appropriate Plus And Smart Switches Forum to discuss Smart Switches (T) and Plus Switches (E), including Local and Remote Management models.
Regards,
-Kurt.

Have you tried to revert the FW back one version on the switch to see if this still happens?
Seems like if this is happening between two same model switches, something connected maybe causing it or something in FW or HW maybe buggy.
Does the LEDs remain on with everything is connected to port 25 the 48 for a long period of time?
Can you give some details on what's all connected to the switch?
I have not tried reverting to a previous firmware version, that is something that we can attempt after hours. Will revert one version back to 6.2.0.31.
- The lights that are working, are working properly. When I unplug something, the lights turn off immediately, as you would expect.
- This switch is a "core" switch, so other edge switches are connected to the first few ports. The other swithes and devices connected to those first few ports are reachable when the lights are off.
- Apart from that, we have a few printers, servers, thin clients and telephones connected to the switch all spread out on various ports including the ones without the lights. I would say, nothing “unusual”.
I performed the downgrade this morning, but it did not have the intended effect. We are now running 6.2.0.31.
As stated before, although the lights are off the ports are functional.
