Nespravovaný síťový switch PLANET GSW-1820HP

The PLANET GSW-1820HP is an unmanaged Gigabit Ethernet switch with integrated Power over Ethernet (PoE) delivering centralized power management for network devices. It provides 16 10/100/1000BASE-T Gigabit Ethernet ports and 2 1000BASE-X SFP interfaces with an internal power system and a total PoE budget of 240 W. The switch supports IEEE 802.3af (up to 15.4 W) and IEEE 802.3at PoE+ (up to 30 W) on all ports and is designed for rack mounting in a 1U enclosure.

Advantages

The GSW-1820HP integrates data switching and power delivery into a single unit, reducing installation time and eliminating the need for separate AC wiring to powered devices. Its combination of 16 gigabit PoE+ ports and two SFP uplinks enables high-speed transmission and long-distance backbone connections. Energy-saving features such as Idle Mode Link Down (IEEE 802.3az) and intelligent power scaling based on cable length help lower overall power consumption. The switch also supports VLAN and an extend mode for increased Ethernet reach.

Suitable for

• Powering and connecting IP surveillance cameras and PoE IP cameras to NVRs
• Supplying PoE to wireless access points and VoIP phones in enterprise or SMB networks
• Small-to-medium rack-mounted network deployments requiring centralized PoE

• Unmanaged switch; rack-mountable 1U form factor; product color: blue; weight: 2.67 kg
• Supported standards: IEEE 802.3, 802.3u, 802.3ab, 802.3z, 802.3af, 802.3at, 802.3az, 802.1Q, 802.3x

How to use

Mount the GSW-1820HP in a standard 19-inch rack or place it on a stable surface. Connect network devices (IP cameras, access points, VoIP phones) to the RJ-45 PoE ports; the switch will automatically negotiate link speed and provide PoE power per the IEEE standard. Use the SFP slots for fiber uplinks to backbone switches or monitoring centers. Set the DIP switch to the appropriate operation mode: Standard for normal PoE+ operation, VLAN to isolate ports and reduce multicast/broadcast impact, or Extend to provide up to 22 W at 10 Mbps over distances up to 250 m on each extended port.

Recommendations

For best results, calculate the total PoE power requirements of connected devices to ensure they do not exceed the 240 W budget. Use the Extend mode only where higher reach is required and bandwidth limitations at 10 Mbps per extended port are acceptable. Choose SFP transceivers compatible with your fiber type (multi-mode or single-mode) and distance requirements.
