Dahua - DH-S4220-16GT-240 - 16-Port PoE Desktop Managed Gigabit Switch (PoE++)
Part number:
DH-S4220-16GT-240
Price:

Equipped with a high performance switching engine, the 16-Port PoE All-Gigabit Managed Switch performs optimally. It has low transmission delay, large buffer and is highly reliable. It also has a strong switching capability and optimizes transmission performance when accessing Ultra HD videos. With its full metal design, the device has great heat dissipation and is low power consumption, working in environments ranging from –10°C to 55°C (+14°F to +131°F). With protection against overvoltage, EMC and overcurrent from power input terminals, the switch effectively resists interference from static electricity, lightning, and pulses. It also has powerful network management functions, supporting various types of web and network management software based on SNMP.

 

Features:

  • Layer 2 network management PoE switch.
  • Supports web, and network management software based on SNMP.
  • Network redundancy: STP/RSTP.
  • Supports PoE power consumption management, PoE power off management.
  • Supports IEEE802.3af, IEEE802.3at.
  • Port 1 and port 2 support IEEE802.3bt, and are compatible with Hi-PoE.
  • Supports PoE watchdog.
  • Supports 250 m long-distance transmission mode.
