Product Usage Instructions

Powering High-Power Devices with Red Ports (90W)

The red ports support IEEE802.3af, IEEE802.3at, Hi-PoE, and
IEEE802.3bt standards with a maximum output power consumption rate
of 90W per port. To power high-power devices, connect them to the
red ports.

Redundant Power Supply

The redundant power supply ensures continuous device operation
even if one power port malfunctions. This feature significantly
enhances device reliability.

PoE Watchdog

The PoE Watchdog feature automatically detects port status and
restarts failed ports to restore connections in case of IPC
connection issues. Enable this feature through the WEB interface
for intelligent operation and maintenance management.

Long-Distance PoE Transmission

By enabling long-distance transmission on the WEB interface,
extend the transmission distance of a PoE port up to 250 meters,
meeting wired transmission requirements (bandwidth reduced to 10
Mbps).

Fast Loop Convergence with ERPS Protocol

Supports the ERPS protocol for loop protection. The switch
ensures fast convergence when network disconnections occur.

Usage Scenarios

The device is suitable for various scenarios, including
corridors and offices.

Frequently Asked Questions (FAQ)

Q: Does the Industrial Switch support Power over Ethernet

(PoE)?

A: Yes, the switch supports PoE with different power levels per
port.

Q: Can I use the PoE Watchdog feature to automatically restart

failed ports?

A: Yes, by enabling the PoE Watchdog feature through the WEB
interface, the switch can automatically detect and restart failed
ports for connection recovery.

Q: What is the maximum transmission distance for Long-Distance

PoE?

A: Long-Distance PoE can extend the transmission distance of a
PoE port up to 250 meters.

DH-IS4420-16GT-240
20-Port Managed Industrial Gigabit Switch with 16-Port PoE(Managed)
· All-gigabit port design. · Supports IEEE802.3af, IEEE802.3at, Hi-PoE and IEEE802.3bt (red port) standards. · 250 m long-distance PoE transmission (10 Mbps). · PoE Watchdog. · Supports STP, RSTP, and ERPS. · IEEE802.1Q-based VLAN configuration. · Manual link aggregation and static LACP. · Desktop mount and DIN-rail mount.

System Overview
Highly reliable, the L2 industrial switch is equipped with a high performance switching engine, has large buffer memory and optimizes transmission performance. With its solid full metal design, the device has great heat dissipation, working in environments ranging from ­40 °C to +75 °C. It also has protection against overcurrent, overvoltage and EMC, resisting interference from static electricity, lightning and pulses. The redundant power supply ensures that the switch performs stably. It can also be remotely managed through the webpage, SNMP and more, and can directly connect to iLinks-View.
Functions

Red Port 90W The red ports support IEEE802.3af, IEEE802.3at, Hi-PoE and IEEE802.3bt standards, with a maximum output power consumption rate of 90W per port. Suitable for powering high-power devices.
Wide Operating Temperature Developed to operate in extreme conditions, the device functions in temperatures ranging from ­40 °C to +75 °C, easily adapting to harsh environments.
Redundant Power Supply Redundant power supply ensures that the device is still powered when one power port malfunctions, vastly improving device reliability.

PoE Watchdog Adopts the innovative PoE Watchdog. PoE Watchdog can be switched on by dialing or turning on the WEB page switch. It enables the switch to automatically detect port status and restart failed ports to recover connection in case of IPC connection exception. This enables intelligent operation and maintenance management in its truest sense, effectively reducing manual maintenance costs.
Long-distance PoE By dialing or enabling long-diatance transmission on the WEB interface, the transmission distance of a PoE port can be up to 250 m, meeting the requirements of wired transmission (bandwidth reduced to 10 Mbps).

Fast Loop Convergence Supports the ERPS protocol to provide loop protection. Fast convergence is performed when the network disconnects.
Scene The device is applicable for use in different scenarios, including corridors and offices.
