1 Overview 

1.1 Introduction 

The Device is a layer-2 commercial switch. It provides a high-performance switching engine and 
large buffer memory to ensure smooth video stream transmission. With a full-metal design, the 
Device has great heat dissipation capabilities on its shell surface, and is able to work in environments 
that range from –10 °C (14 °F) to +55 °C (+131 °F). With its DIP design, it provides a variety of work 
modes that suit different scenarios. The Device also supports power consumption management, 
which allows it to adapt to fluctuations in the power consumption of terminal devices. This ensures 
stable operation. With web management, SNMP and other functions, the Device can be remotely 
managed. It can directly connect to iLinksView. 
The Device is applicable for use in different scenarios, including homes, offices, small malls and on 
server farms. 

1.2 Features 

  16/24 × 100 Mbps PoE Ethernet ports, uplink ports support gigabit optical ports or Ethernet 

ports. 

  All ports meet the requirements of IEEE802.3af and IEEE802.3at standards. The red ports also 

conform with Hi-PoE and IEEE802.3bt standards, and the orange ports conform with Hi-PoE 
standard. 

  250 m long-distance PoE transmissions, which can be configured on the web. 

 

In Extend Mode, the transmission distance of the PoE port is up to 250 m but the transmission 
rate drops to 10 Mbps. The actual transmission distance might vary due to power consumption of 
connected devices or the cable type and status. 

  PoE watchdog for real-time detection of terminal device status, which can be configured on the 

web. 

  Supports STP, RSTP, and MSTP. 

  IEEE802.1Q-based VLAN configuration. 

  Manual link aggregation and static LACP. 

  Desktop mount and rack mount.
