ICS-G24S2X &ICS-G24S4X models are managed industrial grade core switches that provide stable and reliable Ethernet transmission. ICS-G24S2X switches are equipped with 24 Gigabit SFP slots, 4 GbE combo ports and 2 10Gbps SFP+ ports; while ICS-G24S4X switches are with 24 Gigabit SFP slots, 4 GbE combo ports and 4 10Gbps SFP+ ports. These core switches provide a wide variety of redundant mechanisms to increase the reliability of network communications such as redundant and isolated power supplies (2AC, 2DC, 1AC+1DC), STP/RSTP/MSTP and ITU-T G.8032 Ethernet Ring Protection Switching. Apart from redundancy mechanism, advanced layer 2 management functions such as VLAN, QoS, IGMP are also supported. ICS-G24S2X & ICS-G24S4X Series are designed without fans and with IP30 rugged metal housing to meet demands of industrial grade and core layer applications.


Supports IEEE 1588 PTP V2 for precise time synchronization to operate in Ordinary-Boundary, Peer to Peer Transparent Clock, End to End Transparent Clock, Master, Slave mode by each port

Combo Ports

Combo ports

On the front panel, 4 combo ports that are either SFP slot (100/1000Mbps) or RJ-45 UTP (10/100/1000M) interface are provided. Each of these combo ports has associated LEDs which indicate the active link state and the detected speed of the interface. A green indicates a link and a speed of 100M, while yellow color indicates a link and speed of 1000M.



ICS-G24S2X & ICS-G24S4X have a MGMT (Management) port for in-band management via TCP/IP connectivity. The MGMT port allows you to access Command Line Interface (CLI) using Telnet or Web management over TCP/IP using standard web browsers.
When you use the switch for the first time or restore the switch to the factory defaults, you can use RJ-45 cable to directly connect MGMT port to your management PC. Then, run a Telnet facility or web browser to communicate with the device over a TCP/IP network using the default IP address For Telnet connection, up to four active Telnet sessions can access the Switch concurrently. After you successfully login to the switch, you can change the IP address to the desired one.


These switches also have a terminal console port for local management via a serial terminal. The terminal provides management via a CLI (Command Line Interface) which will be familiar to many networking engineers. For most users, the CLI can be used to initially configure TCP/IP access so that further configuration can be completed via the GUI (Graphical User Interface) using a web browser (Chrome, IE, Firefox etc).

Alarm Relay

The Alarm is one electrical relay that can be wired into an alarm circuit and is triggered while the programmable events occur. From the common pin (COM), the relay can be connected as Normally Open (NO) or Normally Closed (NC). When an alarm occurs the NC-to-COM circuit opens and the COM-to-NO circuit closes. See Figure 9 and 10 for normal and fault illustration in each alarm relay type. Please note that the alarm relay contact can only support 1A current at 24VDC. Do not apply voltage and current that exceed these specifications.

Lifetime Support

This product comes with free lifetime telephone support.
