Διακόπτης δικτύου VALUE 21.99.1189 2.5G Ethernet 8 Ports PoE 1U μαύρο

The VALUE 21.99.1189 is a 1U rack-mount 2.5 Gigabit Ethernet switch with eight RJ‑45 ports and one uplink SFP+ port. Four of the RJ‑45 ports support PoE++ and the other four support PoE+, enabling the switch to power PoE‑capable devices such as access points, IP phones and network cameras while providing 2.5G line rates, full duplex operation and a switching capacity of 60 Gbit/s. The switch is suitable as a central device for small networks or as an access-layer edge switch in larger deployments and complies with relevant IEEE standards.

Advantages

This VALUE 2.5G Ethernet switch offers multi‑gigabit speeds on all eight RJ‑45 ports (100/1000/2500), integrated PoE capabilities (four PoE++ and four PoE+ ports), a dedicated SFP+ uplink for higher‑speed aggregation, and a compact 1U rackable form factor. It supports a MAC address table of 4000 entries and industry networking standards (IEEE 802.3x, 802.3u, 802.3i, 802.3bt, 802.3at, 802.3af), providing predictable performance and interoperability in mixed environments.

Suitable for

• Small office or branch networks as a central switch
• Access-layer edge switch in medium or larger networks
• Powering PoE devices such as access points, IP phones and PoE cameras
• Rack-mounted installations in wiring closets or server rooms (1U)

Key specifications

• Ports: 8 × RJ‑45 2.5G (100/1000/2500), 1 × SFP+ uplink
• PoE: 4 ports PoE++ and 4 ports PoE+
• Switching capacity: 60 Gbit/s
• MAC address table: 4000 entries
• Networking standards: IEEE 802.3x, 802.3u, 802.3i, 802.3bt, 802.3at, 802.3af
• Form factor: 1U rack-mount
• Color: Black
• Weight: 1.1155 kg

How to use

Install the switch in a 19" rack using the 1U mounting provisions or place it on a stable surface. Connect the uplink SFP+ port to your aggregation or core switch if higher-speed backhaul is required, or use standard Ethernet cabling to connect to other network devices. Connect PoE devices to the RJ‑45 PoE ports; the switch will convert AC mains power to the low-voltage DC delivered over the Ethernet cable to power compliant devices. Configure basic network settings (VLANs, link speeds) on connected devices as needed for your network design.

Recommendations

For reliable operation, mount the switch in a ventilated rack space, use proper SFP+ modules compatible with your fiber or DAC cabling, and ensure total PoE power budget and connected device requirements are within the switch’s supported limits. Follow standard grounding and cable management practices.
