16x 10/100BaseT + 8x SFP with 8/16x PoE

CT- IFS-1608GSM-16PH/8PH

  • Managed, industrial grade, L2 PoE (Power over Ethernet)
  • Rugged DIN rail or wall mountable IP-30 enclosure
  • Cable diagnostics, identifies opens/shorts distance
  • μ-Ring for redundant cabling, recovery time<10ms in 250 devices
  • IEEE 1588 PTP V2 for precise time synchronization
  • SmartConfig mass Configuration Tool
  • SmartView Centralized Management Tool


These models are managed, industrial    grade, L2 PoE (Power over Ethernet) switches that    provide16x 10/100Base-TX ports plus 8x 100/1000Base-X SFP ports with 16/8x PoEPorts. The PoE features enable power and data to be transferred via a single cable, thereby considerably reducing cabling and electrical wiring expenses. Housed in rugged DIN rail or wall mountable IP-30 enclosures, these switches are the perfect choice for harsh environments, such as industrial networks, intelligent transportation systems (ITS) and are also suitable for many military and utility applications where environmental conditions exceed commercial product specifications.

These switches can also operate either at standard operating temperature range (-10 to 60°C) or at wide operating temperature range (-40 to 75°C) to fulfill the special needs of industrial automation applications.



Technical Notes

What is Power over Ethernet ?

Power over Ethernet, commonly abbreviated to PoE, is a technology that enables DC power to be delivered over the same twisted pair copper cabling as the data. This allows end devices such as IP phones, CCTV cameras and wireless access points to receive power across the network and avoids the need to install electrical cabling and a power source at the remote end.
