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 to +55 °C (+14 °F to +131 °F). 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. The Device also supports ePoE long distance transmission function, 
and is equipped with three types of self-adaptation transmission modes: IEEE, E100 and E10. 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 orange ports 

conform with Hi-PoE standard. 

  Supports ePoE long distance transmission, equipped with three types of self-adaptation 

transmission modes, including IEEE, E100 and E10. 

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

web. 

  Supports STP and RSTP. 

  IEEE802.1Q-based VLAN configuration. 

  Manual link aggregation and static LACP. 

  Desktop mount and rack mount.
