We have a TP Link PoE+ switch model TL-SG1218MPE connected in our LAN network. The PoE powered devices (PD)connected to this switch are display counters of 8 numbers. At initial configuration it is found that the ping to the default IP of the switch 192.168.0.1 is taking too much delay at a maximum of 90ms sometimes and also shows a very non-uniform time delays.

We configured a management static IP to the the switch and connected in our network. 8 numbers of Display counters also connected to the switch as PoE powered devices (PD). From the beginning itself the PoE powered counter displays are getting the power supply, but sometimes the counter displays become freeze without any data coming to them. After reboot of the switch the counter displays will get data and functions properly. At the same time of the issue persists, we can get the ping to these PoE powered counter displays and but a minimum of 1 packets out of 2000 packets loss happens. Also the ping to the switch management IP also shows packet loss up to 3 packets out of 2000 packets

It is also found that the RxBadPkt in the optical fiber uplink is very higher of 54735. The screenshot of the same is attached below.

We change the uplink ports and checked then . The issue of freezing the PoE powered counter displays still happened then.

It is a daily routine to reboot the switch twice a day for the working of the PoE powered counter displays and become a burden to the staff.

Please help me out to resolve this issue? Is this any issue with current firmware version of the switch. The current firmware version is  1.0.0 Build 20221012 Rel.42630. Is the firmware version upgrade to the latest one resolves the problem?.

Appreciate your valuable suggestions to this query
