3. Hardware Description
3.1 Front View
The front panel features one RJ45 twisted-pair jack (auto-MDI/MDI-X) with one "PoE In" LED indicator, one 100/1000X SFP fiber-optic slot, four LED indicators, and one DIP switch for Link-Fault Passthrough (LFP) feature. When the DIP switch is turned on, the LLCF and LLR are activated.
Diagram Description (Figure 1: GT-805A-PD Front View): Depicts the front panel of the converter, showing the RJ45 port labeled "10/100/1000T", the SFP slot labeled "100/1000X", LEDs for "PWR", "1000", "ACT", "LNK", and "PoE In", and a DIP switch labeled "LFP" with "ON" and "OFF" positions.
? The Gigabit Ethernet PoE PD media converter provides two power input systems: IEEE 802.3af/at/bt 48V~54V DC in-line power via the 10/100/1000T RJ45 port or optional 5V DC input via a DC jack on the rear panel.
3.2 LED Indication
System
| LED | Color | Function |
|---|---|---|
| PWR | Green | Lit: To indicate that the Gigabit Ethernet PoE PD media converter has power. Off: To indicate that the power is not detected. |
100/1000BASE-X SFP Slot
| LED | Color | Function |
|---|---|---|
| Fiber LNK/ACT | Green | Lit: To indicate the link through fiber port is successfully established. Blink: To indicate the fiber port is actively sending or receiving data. Off: To indicate that the fiber optic port is linked down. |
3.3 Rear View
The rear panel of the Gigabit Ethernet PoE PD media converter features one DC jack, which accepts input power of 5V DC @ 2A.
Diagram Description (Figure 2: GT-805A-PD Rear View): Shows the rear panel with a DC jack labeled "5V DC".
? The default package of the Gigabit Ethernet PoE PD media converter does not include a DC 5V power adapter. If you need this DC 5V power adapter, please contact your local dealer or distributor for more assistance.
3.4 Power Information
The power jack of the Gigabit Ethernet PoE PD media converter measures 2.5mm in the central post and requires +5VDC power input. It conforms to the bundled AC-DC adapter and PLANET's media chassis. For power connection issues, please contact your local sales representative.
Diagram Description: Illustrates a 2.5mm DC receptacle, noting "+5V for each slot". It states the DC receptacle is 2.5mm wide, conforming to the converter's 2.5mm DC jack's central post, and warns against installing improper units.
4. Link Fault Pass-through (LFP)
This function includes the Link Fault Passthrough (LFP) and a DIP switch. LFP comprises Link Loss Carry Forward (LLCF) and Link Loss Return (LLR), which alert administrators to link media issues and provide solutions. The DIP Switch enables or disables the LFP function.
LLCF: When the TP line loses its link, the converter's fiber will disconnect transmission. LLR: When the fiber line loses its link, the converter's fiber will disconnect transmission.
? LFP function is ON by default. If you are familiar with network installation and require diagnostic purposes (e.g., checking which end is broken), you can turn it off and reset the converter. Otherwise, keep it in the default position.
Diagram Description: Illustrates the GT-805A-PD connected to a PoE device via a 100-meter UTP cable, and to a Gigabit Fiber Switch via fiber optic cables (distances vary by type, e.g., 220m-120km). It highlights "No Power Outlet Required" for the GT-805A-PD.
5. Installation
5.1 Before Installation
The GT-805A-PD is powered by a PSE (Power Source Equipment) and forwards Ethernet data to the remote media converter. It does not require an external power supply and is plug-and-play, without affecting data transmission performance.
? 1. For optimal PoE power and data extension quality, use "Solid UTP Cable" when installing the GT-805A-PD.
? 2. The GT-805A-PD can be installed with a third-party device if it complies with the IEEE 802.3af/at/bt standard.
5.2 Connecting GT-805A-PD to Power Source Equipment (PSE)
This section details the installation and connection process. The "RJ45 PoE IN" port serves as "PoE (Data and Power) input".
Step 1: Slide in the SFP transceiver module and connect the fiber cable from the GT-805A-PD to the fiber network.
Step 2: Connect a standard Cat5e/6 UTP cable from the power source equipment (PSE), such as a PoE switch, PoE injector hub, or single-port PoE injector, to the "PoE IN" port of the GT-805A-PD.
