24+4G-port Gigabit modular managed PoE+ Ethernet switches

Product Feature

  • 8 built-in PoE+ ports compliant with IEEE 802.3af/at (IKS-6728A-8PoE)
  • Up to 36 W output per PoE+ port (IKS-6728A-8PoE)
  • 1 kV LAN surge protection for extreme outdoor environments
  • PoE diagnostics for powered-device mode analysis
  • 4 Gigabit combo ports for high-bandwidth communication
  • -40 to 75°C operating temperature range at 720 W full loading
  • Supports MXstudio for easy, visualized industrial network management
  • V-ON™ ensures millisecond-level multicast data and video network recovery


The IKS-6728A Series is designed to meet the demands of mission-critical applications for business and industry. The IKS-6728A and IKS-6728A-8PoE come with up to 24 10/100BaseT(X), or PoE/PoE+, and 4 combo Gigabit Ethernet ports. The IKS-6728A-8PoE Ethernet switches provide up to 30 watts of power per PoE+ port in standard mode, and also support high-power output of up to 36 watts for heavy-duty industrial PoE devices, such as weather-proof IP surveillance cameras with wipers/heaters, high-performance wireless access points, and rugged IP phones.

IKS-6728A-8PoE Ethernet switches support two types of power input sources: 48 VDC for PoE+ ports and system power, and 110/220 VAC for system power. These Ethernet switches also support a variety of management functions, including STP/RSTP, Turbo Ring, Turbo Chain, PoE power management, PoE device auto-checking, PoE power scheduling, PoE diagnostic, IGMP, VLAN, QoS, RMON, bandwidth management, and port mirroring. The IKS-6728A-8PoE is designed especially for harsh outdoor applications with 3kV surge protection to ensure the uninterrupted reliability of PoE systems.


Additional Features and Benefits

  • Advanced PoE management functions: PoE output setting, PD failure check, PoE scheduling, and PoE diagnostics
  • Command line interface (CLI) for quickly configuring major managed functions
  • DHCP Option 82 for IP address assignment with different policies
  • Supports EtherNet/IP, PROFINET, and Modbus TCP protocols for device management and monitoring
  • Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), and STP/RSTP/MSTP for network redundancy
  • IGMP snooping and GMRP for filtering multicast traffic
  • Port-based VLAN, IEEE 802.1Q VLAN, and GVRP to ease network planning
  • QoS (IEEE 802.1p/1Q and TOS/DiffServ) to increase determinism
  • IEEE 802.3ad, LACP for optimum bandwidth utilization
  • TACACS+, IEEE 802.1X, SNMPv3, HTTPS, and SSH to enhance network security
  • SNMPv1/v2c/v3 for different levels of network management
  • RMON for proactive and efficient network monitoring
  • Bandwidth management prevents unpredictable network status with “Lock port” to restrict access to authorized MAC addresses
  • Port mirroring for online debugging
  • Automatic warning by exception through email and relay output
  • Automatic recovery of connected device’s IP addresses
  • Line-swap fast recovery
  • Configurable by web browser, Telnet/serial console, CLI, Windows utility, and ABC-02-USB automatic backup configurator
