FAQ
Common questions about LY21-2 16-port and 24-port RJ45 network surge protector selection.
Wofür wird der Überspannungsschutz LY21-2 CAT16/CAT24 verwendet?
Es bietet zentralen Überspannungsschutz für sechzehn oder vierundzwanzig RJ45-Ethernet-Datenleitungen, die mit Switches, Servern, Modems, Überwachungssystemen und anderer Netzwerkausrüstung verbunden sind.
Was ist der Unterschied zwischen CAT16 und CAT24?
CAT16 schützt sechzehn unabhängige RJ45-Netzwerkkanäle, während CAT24 vierundzwanzig Kanäle schützt. In diesem Produktnamen beschreiben CAT16 und CAT24 die Portkonfiguration und nicht eine Ethernet-Kabelkategorie.
Ist dieses Modell für PoE-Netzwerke geeignet?
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.
Was sollte vor der Bestellung bestätigt werden?
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.
