TPLINK SWITCH - TL-SG1005P
At church, we have a TPLINK SWITCH - TL-SG1005P connected to our Comcast modem. It feeds an access point in same building, and another access point in a 2nd building. We have burned out two of these switches. Yet another backup spare switch seems to work just fine. I think that the spare is a NETGEAR 16-Port Gigabit Ethernet Unmanaged Switch. I substituted the NETGEAR in for a week or two when the first TL-SG1005P burned out. When we planned this whole system with our IT consultant, we planned and designed to prevent surge issues from happening. We have an APC surge/battery powering modem and switch. We have ethernet cable surge protectors (grounded ONLY on the upstream end). The outdoor ethernet cable is buried and not near underground A/C cables. We have NO outdoor ethernet devices. The 2nd building access point has its OWN power injector, so the cable to the second building is using the NON-POE port on the TL-SG1005P. The TL-SG1005P sits directly on top of a metal file cabinet, so it should NOT get too warm. BUT, it always felt a little warm. Both TL-SG1005P units burned out in their first month or two. We have NO steeple. NONE of the ports on the second TL-SG1005P light up at this point, so I am returning it to our supplier. I could hire an electrician to double check any voltage differences between the two buildings:
- Ground-to-ground voltage
- Neutral-to-ground issues
If I cannot avoid switch burnout, I may ask the board to let us install fiber between the two buildings, as our IT consultant recommended this at the start to avoid surge issues. But this will be a lot of work. Might a dirfferent brand, more expensive switch, be helpful here? Any suggestions? Thanks. Rick.
