FAQ
Common questions about LY21-2 RJ45 network signal surge protector selection and installation.
Apa yang digunakan pelindung lonjakan LY21-2 RJ45?
LY21-2 dipasang secara inline dengan kabel jaringan RJ45 untuk membantu mencegah lonjakan tegangan yang disebabkan oleh petir dan transien saklar mencapai switch, server, modem, pengontrol, dan peralatan jaringan lainnya.
Apakah model ini cocok untuk peralatan PoE?
FAQ produk saat ini mengidentifikasi versi ini sebagai pelindung lonjakan data non-PoE. Untuk kamera PoE atau perangkat Ethernet bertenaga, pilih SPD yang kompatibel dengan PoE dengan tegangan daya, arus, mode pengkabelan, dan tarif data yang benar.
Kecepatan jaringan apa yang didukung oleh LY21-2?
The listed maximum transmission rate is 100Mbps. It should not be selected for Gigabit Ethernet unless a separate tested Gigabit-compatible version is confirmed.
Will the surge protector affect network performance?
Its listed insertion loss is no more than 0.2dB. Actual compatibility should still be checked against the network speed, cable category, cable length, impedance, and connected equipment.
How should LY21-2 be installed?
Install it inline with the Ethernet cable and as close as practical to the protected network equipment. Follow the input and protected-side markings and provide a short, direct grounding connection where required.
Apa yang harus dikonfirmasi sebelum memesan?
Confirm whether the line is PoE or non-PoE, the Ethernet speed, operating voltage, protected pin configuration, cable category, interface direction, grounding method, installation location, and required surge withstand level.
