FAQ
Common questions about LY21-2 16-port and 24-port RJ45 network surge protector selection.
A cosa serve il proteggitore contro le sovratensioni LY21-2 CAT16/CAT24?
Fornisce protezione centralizzata contro le sovratensioni per sedici o ventiquattro linee di dati Ethernet RJ45 collegate a switch, server, modem, sistemi di monitoraggio e altre apparecchiature di rete.
Qual è la differenza tra CAT16 e CAT24?
CAT16 protegge sedici canali di rete indipendenti RJ45, mentre CAT24 protegge ventiquattro canali. In questo nome di prodotto, CAT16 e CAT24 descrivono la configurazione della porta piuttosto che una categoria di cavo Ethernet.
Questo modello è adatto per reti PoE?
The listed CAT16/CAT24 version is designed for network data lines and does not include the separate 60V PoE power-section ratings shown for the LY21-2 PoE model. Use a confirmed PoE-compatible protector for powered Ethernet equipment.
What Ethernet speed does the protector support?
The listed maximum transmission rate is 100Mbps. Do not describe the product as Gigabit-compatible unless separate test data confirms Gigabit Ethernet performance.
Where should the multi-port protector be installed?
Install it in the network or security cabinet near the protected switch, server, modem, network recorder, or other centralized network equipment.
Cosa dovrebbe essere confermato prima di ordinare?
Confirm whether sixteen or twenty-four ports are required, whether the network is PoE or non-PoE, the Ethernet speed, RJ45 pin configuration, cable category, grounding method, cabinet space, and required surge withstand level.
