Prama PT‑SW3U10P‑E is a compact 10‑port unmanaged PoE switch with 8× 10/100 Mbps PoE ports and 2× 10/100/1000 Mbps Gigabit uplink RJ45 ports. It complies with IEEE 802.3, 802.3u & 802.3x standards, supports IEEE 802.3af PoE power supply, and provides VLAN, Default, and Extend operating modes, including PoE watchdog auto‑activation in VLAN and Extend modes. This makes it ideal for medium‑size IP camera systems, small offices, and home networks where you need to power and connect multiple PoE devices over a single Ethernet cable without manual configuration.

Port configuration

• PoE ports: 8 × 10/100 Mbps RJ45 PoE ports (ports 1–8, data + power).

• Uplink ports: 2 × 10/100/1000 Mbps RJ45 Gigabit uplink ports (ports 9–10, data only).

• Total ports: 10 RJ45 ports (8 PoE + 2 Gigabit uplink).

The 2× Gigabit uplink ports provide higher backbone bandwidth to the router/NVR, reducing congestion in multi‑camera or multi‑switch setups.

Standards and PoE support

• Complies with IEEE 802.3, IEEE 802.3u, and IEEE 802.3x Ethernet standards.

• PoE standard support: IEEE 802.3af (15.4 W per port typical).

• RJ45 ports support 10/100 Mbps adaptive speed for PoE ports and 10/100/1000 Mbps for uplink ports.

• Auto MDI/MDIX (automatic port flipping) and flow control: IEEE 802.3x (full duplex) + backpressure (half duplex).

Operating modes and extend capability

• Default mode:

  • All ports (1–10): 10/100 Mbps (PoE ports) and 10/100/1000 Mbps (uplink ports), up to 100 m, PoE watchdog mode is off.

• VLAN mode:

  • PoE ports (1–8) are isolated from each other but can communicate with the uplink ports.

  • PoE ports automatically enable watchdog mode for fault recovery.

• Extend mode:

  • PoE ports (1–8): 10 Mbps up to 250 m.

  • Uplink ports (9–10): 100 Mbps up to 100 m.

  • PoE ports auto‑enable watchdog mode for stable long‑distance operation.

Extend mode allows long‑distance cable runs for IP cameras in parking lots, perimeters, and large facilities.

Power and protection

• 8 RJ45 PoE ports support IEEE 802.3af standard PoE power supply, with maximum single‑port power up to 15.4 W and machine maximum 120 W total.

• The switch can automatically detect and identify devices that meet the IEEE 802.3af standard and supply power through the network cable using a priority mechanism.

• Designed with high‑speed Ethernet switching chip and ultra‑high backplane bandwidth for smooth data transmission.

Physical and environmental specs

• Form factor: desktop/compact 1U‑style housing (non‑rack‑mount).

• Power supply: Built‑in switching power supply, typically AC 220 V, 50 Hz (region‑specific).

• Operating temperature: –20 °C to 55 °C.

• Storage temperature: –40 °C to 75 °C.

• Humidity: 10%–90% RH (non‑condensing).
