ISON IS-RG528HS20-28F-2A


Industrial 28 port Gigabit Layer 2 Managed Switch, 28 SFP Slot, Hot-Swap Power, Dual AC, 20KV Lightning Protection, -40~75ºC



The IS-RG528HS Series are 28-port full Gigabit Managed Ethernet Switches with hot-swappable redundant power supplies perfect for upgrading an existing network to a full Gigabit Speed Infrastructure; a full Gigabit network provides higher throughput than legacy (10/100Mbs) Fast Ethernet network. The IS-RG528HS Series reduces the response times for time sensitive applications which may be a mix of video, voice, and data streams in the traffic flow. With the powerful S/W and H/W features, the IS-RG528HS Series prioritizes, partitions and optimizes the user’s network while providing reliable quality of service. The IS-RG528HS Series switches are suitable for access level network connection.
