Hallitsematon kytkin ALLNET ALL-SG8208PD

The ALLNET ALL-SG8208PD is an unmanaged Gigabit Ethernet switch with eight 10/100/1000 Mbps RJ-45 ports that support auto-negotiation (NWay) and full duplex operation. Designed for straightforward network expansion, the switch enables micro-segmentation of larger networks to improve performance for bandwidth-demanding multimedia and imaging applications. It also supports easy migration from 10/100 Mbps to 1000 Mbps networks and includes a MAC address table of 4000 entries for reliable frame forwarding.

Advantages

This switch combines high-speed Gigabit connectivity with PoE pass-through functionality, offering both PD (Powered Device) and PSE (Power Sourcing Equipment) capabilities in a single unit. Four PSE ports can supply power to connected devices while the unit can receive power on its PD port from an upstream PSE, simplifying cabling by carrying data and power over CAT5e or better twisted-pair cables. The device is plug-and-play with no software configuration required and includes over-current and short-circuit protection plus front-panel LEDs for per-port and system status diagnostics.

Suitable for

• Small office or branch networks requiring Gigabit uplinks.
• Connecting and powering PoE devices such as wireless access points and VoIP phones.
• Segmenting larger LANs into smaller subnets to improve performance for multimedia and imaging traffic.

Key specifications

• Ports: 8 × RJ-45 Gigabit Ethernet (10/100/1000 Mbps) with auto-negotiation and full duplex
• PoE: PoE pass-through with PD and 4 PSE ports (power over CAT5e or better)
• Switch type: Unmanaged
• Standards: IEEE 802.3, 802.3u, 802.3x, 802.3ab, 802.1p, 802.3at
• MAC address table: 4000 entries
• Colour: Black
• Weight: 0.4 kg

How to use

Connect network devices to the switch using Cat5e or better Ethernet cables. If using PoE, plug the upstream PSE into the switch PD port to power the unit and connect PoE-powered devices to the PSE ports; the switch will pass data and supply power over the same cable. No configuration is required — the switch performs auto-negotiation for link speed and duplex. Monitor operation and link status using the front-panel LED indicators.

Recommendations

Place the switch in a ventilated, dry environment and use CAT5e or higher cabling for optimal Gigabit performance. Ensure connected PSE devices comply with IEEE 802.3at where required and avoid exceeding the power budget on PSE ports. Regularly check LED indicators to identify link or power issues.
