S8455 Series

The NPort® S8455 series combines an industrial device server with

a full-function managed Ethernet switch by integrating 2 fiber ports,

3 Ethernet ports, and 4 RS-232/422/485 serial ports, allowing you

to easily install, manage, and maintain the product. Combining a

The NPort® S8455 series supports the complete array of NPort®

5000 series device server functions. You can network your existing

serial devices by connecting up to 4 serial devices through each of the

are very critical since they are used to control and monitor device

processes. The reliability of these communications depends on ring

redundancy at the device level. which is

designed to provide fast network fault

detection and reconfiguration in order

to support the most demanding control

applications.

The NPort® S8455 series integrates a

full function NPort® device server with

an industrial switch to carry serial and

Ethernet devices at the same time. In

addition, the NPort® S8455 can also

achieve ring redundancy with standard

The NPort® S8455 series has a built-in full-function managed

Ethernet switch that supports QoS, IGMP-snooping/GMRP, VLAN, Port

Trunking, SNMPv1/v2c/v3, and IEEE 802.1X, allowing you to handle

virtually any kind of application. Ethernet redundancy, which is used

your cabinet, reduce overall power consumption, and reduce costs,

since you will not need to purchase a switch and serial device server

data transmission between the serial and Ethernet interfaces is

bi-directional.
