4. Product Overview
The Planet GPL-8000 is a robust Optical Line Terminal designed for high-density GPON deployments. Below is an illustration of the device's front panel, highlighting its various ports and indicators.
Figure 1: Front Panel of the Planet GPL-8000 OLT. This image displays the front of the GPL-8000 unit, featuring a series of ports and LED indicators. From left to right, it includes power and system status LEDs, a console port, management (MGMT) ports, Gigabit TP/SFP combo ports (G1-G8), 10G SFP+ ports (TG1-TG4), and GPON ports (P1-P8). The Planet logo and model number GPL-8000 are visible on the right side.
4.1 Front Panel Components
- LED Indicators:
- PWR1/PWR2: Power status indicators.
- SYS: System status indicator.
- ALM: Alarm indicator.
- LNK/ACT (1G/10G): Link/Activity indicators for Gigabit and 10G ports.
- PON (P1-P8): GPON port status indicators.
- Console Port: For local management access (RJ45).
- MGMT Port: Dedicated Ethernet port for out-of-band management.
- Gigabit TP/SFP Combo Ports (G1-G8): Four pairs of ports, each offering a Gigabit Ethernet (RJ45) and a Gigabit SFP slot. Only one interface in each combo pair can be active at a time.
- 10G SFP+ Ports (TG1-TG4): Four 10-Gigabit SFP+ slots for high-speed uplinks.
- GPON Ports (P1-P8): Eight GPON (Gigabit Passive Optical Network) ports for connecting to ONUs/HGUs.
5. Setup and Installation
5.1 Physical Installation
- Rack Mounting: Secure the GPL-8000 into a standard 19-inch equipment rack using the provided rack-mounting kit. Ensure adequate ventilation around the unit.
- Power Connection: Connect the power cord to the device's power input and then to a grounded AC power outlet. Verify that the PWR LED illuminates.
- Grounding: Connect a grounding wire from the device's grounding screw to a proper earth ground.
5.2 Initial Network Connection
- Management Port: Connect an Ethernet cable from your management workstation to the dedicated MGMT port on the GPL-8000.
- Console Port (Optional): For direct command-line interface (CLI) access, connect a console cable from your workstation to the Console port. Configure your terminal emulator with settings: 9600 baud rate, 8 data bits, no parity, 1 stop bit (9600, N, 8, 1).
- Uplink Connections: Connect your network's uplink cables to the 10G SFP+ ports (TG1-TG4) or the Gigabit TP/SFP Combo ports (G1-G8) as required.
- GPON Connections: Insert appropriate GPON optical modules into the GPON ports (P1-P8) and connect the fiber optic cables to your GPON network.
6. Operating Instructions
6.1 Accessing the Device
The GPL-8000 can be managed via a web-based GUI, CLI (Console/Telnet/SSH), or SNMP.
- Web GUI: Open a web browser and enter the device's IP address (default IP address can be found in the Quick Installation Guide or by using the console).
- CLI: Use a terminal emulator connected to the console port or establish a Telnet/SSH session to the device's IP address.
6.2 Basic Configuration
Refer to the detailed software user manual for advanced configuration. Key initial steps typically include:
- Changing the default administrator password.
- Configuring the management IP address.
- Setting up GPON service profiles and registering ONUs/HGUs.
- Configuring VLANs and QoS settings.
7. Maintenance
- Cleaning: Periodically clean the device's exterior with a soft, dry cloth. Ensure ventilation openings are free from dust and obstructions. Do not use liquid or aerosol cleaners.
- Firmware Updates: Regularly check the Planet website for firmware updates to ensure optimal performance and security. Follow the provided instructions for firmware upgrade procedures.
- Environmental Monitoring: Ensure the operating environment remains within specified temperature and humidity limits to prevent hardware degradation.
8. Troubleshooting
This section addresses common issues you might encounter with the GPL-8000.
- No Power:
- Verify the power cord is securely connected to both the device and the power outlet.
- Check the power outlet for functionality.
- Ensure the PWR LED is illuminated.
- No Link on a Port:
- Check the cable connection for both ends.
- Ensure the correct cable type is used (e.g., fiber for SFP/GPON, Ethernet for TP).
- Verify the connected device is powered on and functioning correctly.
- For SFP/SFP+ ports, ensure the correct transceiver module is inserted.
- For GPON ports, check fiber integrity and ONU registration status.
- Cannot Access Web GUI/CLI:
- Verify your management workstation's IP address is in the same subnet as the GPL-8000's management IP.
- Check physical connection to the MGMT or Console port.
- Ensure no firewall is blocking access.
- Reset the device to factory defaults (refer to the full user manual for procedure) if the IP address is unknown or forgotten.
