Important Notice:
Power supply is NOT included. Please use a suitable 12–56V DC switching power supply. Up to 8A via the 5.08mm terminal block.450W(56V8A) max via the 5.08mm terminal block.
Passive PoE — no IEEE power negotiation. The PoE ports are always powered. Do NOT connect non-PoE devices to the PoE ports.

The DSLRKIT P1G-4CH-4PAIR-MID adds power to an existing switch or router through four 10/100/1000Mbps channels. Each LAN IN connects to its matching PoE OUT; each channel needs its own upstream LAN port.

Compatible with IEEE 802.3af (PoE), 802.3at (PoE+) and 802.3bt (PoE++) powered devices. This passive injector does not perform IEEE power negotiation. Some PDs requiring active PoE may limit power or fail to start. Confirm voltage and pinout. Do not connect non-PoE equipment directly to PoE OUT.

4-pair power: up to 2A/port. 2-pair Mode A or B: up to 1.1A per path. A suitable 52-56V supply enables up to 90W per output before cable loss. Applications include high-power IEEE 802.3bt (PoE++) splitters, IEEE 802.3bt (PoE++)-powered passthrough switches, wireless access points, wireless bridges, IP cameras and VoIP phones.

Use ONE DC input: 5.08mm terminal, 12-56V/8A max total; or 5.5 x 2.5mm center-positive jack, 12-56V/6A max total. Maximum terminal input: 56V x 8A = 448W (approx. 450W). No voltage conversion; all outputs share one supply voltage. Pins 1/2/4/5 positive; 3/6/7/8 negative.

Eight resettable PTCs: one per Mode A/B path. In 2-pair use, one PTC protects the active path; in 4-pair use, both operate, each protecting its own path. Includes N-MOSFET input reverse-polarity protection, transient suppression and a chassis grounding point.

Upper and lower thermal pads transfer heat to the metal case. For frequent full-load use or prolonged operation above 5A total input current, provide good ventilation or mount to a heat-dissipating metal surface. Available output depends on the supply, cables and cooling.

Body: 106 x 40.6 x 25.6mm. Net weight: 150g. Gross weight with accessories and packaging: 240g.

Includes 1 midspan, 4 x 0.2m Ethernet cables, 2 mounting brackets and 1 removable 5.08mm terminal plug, supplied fitted to the unit. Power supply not included.

Specifications and Enclosure Markings
Model: P1G-4CH-4PAIR-MID
Body dimensions (L x W x H): 106 x 40.6 x 25.6mm (4.17 x 1.60 x 1.01in)
Net weight (midspan only): 150g (5.29oz)
Gross weight (including accessories and packaging): 240g (8.47oz)
Network: 4 independent 10/100/1000Mbps channels; 4 LAN IN + 4 PoE OUT
Power type: Passive, no detection or negotiation
PD compatibility: IEEE 802.3af (PoE), 802.3at (PoE+) and 802.3bt (PoE++) powered devices. Some PDs requiring active PoE negotiation may limit power or fail to start; confirm device voltage and pinout.
4-Pair Power: 2.0A maximum continuous per port; 2.2A peak as marked, not a continuous rating
2-Pair Power: 1.1A maximum when drawing from one Mode A or Mode B path
Mode A: Pins 1/2 positive, 3/6 negative
Mode B: Pins 4/5 positive, 7/8 negative
Mode selection: Both paths are energized when powered; no automatic or manual A/B mode selection
Terminal input: 2-pin, 5.08mm pitch, 12-56V DC, 8A maximum total
Maximum DC input power: 56V x 8A = 448W (approximately 450W), via the 5.08mm terminal
Barrel input: 5.5 x 2.5mm, center positive, 12-56V DC, 6A maximum total
USE ONE DC INPUT ONLY: Never connect both power inputs simultaneously
Voltage: No step-up, step-down or per-port voltage adjustment
Use 48-56V PSU for 802.3af/at/bt devices: Match the supply voltage to the device; use a suitable 52-56V supply for high-power operation. This passive midspan does not perform IEEE power negotiation.
Ground symbol: Chassis/shield bonding point; connect to installation ground as appropriate
Protection: 8 resettable PTCs, one per Mode A/B path on each port. Two-pair use: one PTC protects the active path. Four-pair use: both operate, each protecting its own path. Input N-MOSFET reverse-polarity protection and transient suppression are included.
Cooling: Metal enclosure with upper and lower thermal pads; ventilation or a heat-dissipating metal mounting surface required for frequent full load or prolonged operation above 5A total
