PoE Network Switches

IES48242MPp-S New!

L2+ Managed 48-port 10/100/1000Base-TX (PoE+) + 4-port 1000Base-SFP Ethernet Switch

Main Features -

Built-in Unique PoE Management Functions

Intelligent Power Recycling

  • The network switch monitors transmission of data packets from powered devices (PDs) in real-time.
  • The PoE of the Ethernet port will be reset in order to reboot the PD.

PoE Schedule for Energy Savings

  • PoE scheduling can be pre-set on each PoE port to turn on/off PoE and set output power according to the schedule.

PoE Usage Monitoring

  • Info such as voltage, current and temperature are available on web management interface.


  • Enhances the management efficiently of facilities.

PoE+ Power and Ethernet Data Transmission Distance Extension

  • Breaking the 100-meter limit, the PoE extending function can further extend Data and PoE up to 250 meters on UTP cable at 10Mbps for up to 16 PDs with 30W power output.

Redundant Ring

  • IES48242MPp-S supports redundant ring and features strong, rapid self-recovery capability to prevent interruptions and external intrusions. It incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching) technology, Spanning Tree Protocol (802.1s MSTP) into customer’s network to enhance system reliability and uptime in various environments.
  • The recovery time could be less than 20ms to quickly bring the network back to normal operation.
  • The series is also a good solution for 24hr non-stop operation, providing maximum reliability and productivity.

Trap Event Alert via CLI/Web/SNMP

  • IES48242MPp-S provides event alert function, by triggering notification through CLI/Web/SNMP and system log, when there is malfunction in the network.


Other Features -

  • L2+ Managed features provide easier manageability, robust security and QoS
  • Supports up to 48 × 10/100/1000Base-TX PoE + 4 x 100/1000Base-SFP
  • Support IEEE 802.3af/at (up to 30W)
  • Support Auto-MDIX, and Full/Half Duplex self-negotiation mode
  • 16K MAC address table
  • Support 10K bytes jumbo frame, compatible with various extension protocols
  • Electric 4KV surge protection
  • IEEE 802.1Q tagged 4K VLANs groups, out of 4094 VLAN IDs
  • Supports provider bridging (VLAN Q-in-Q, IEEE 802.1ad)
  • IGMP v1, v2, v3 Snooping
  • AC Power Input
