This method is ideal for professional network environments where equipment is housed in racks, ensuring an organized and secure setup. Adequate space should be reserved for cabinet doors to facilitate maintenance, and proper cable management brackets should be used.
- Workbench Placement: For users without a standard cabinet, the router can be placed on a clean workbench. This involves attaching four rubber pads to the bottom corners of the device to ensure stability and prevent scratching. When placed on a workbench, it is crucial to ensure good ventilation around the router to maintain optimal operating temperatures.
Power Supply and Grounding: The router uses a 3-conductor AC power input, compatible with 100V to 240V, 50Hz/60Hz electrical systems. It is recommended to use a single-phase 3-conductor outlet or a multifunction microcomputer outlet with a neutral connector. Proper grounding is paramount for safety and stable operation. The device features a PGND (Protective Ground) pole on its back panel, which should be connected to the grounding lug of the rack and then to the grounding bar of the equipment room. This ensures protection against lightning strikes and electromagnetic interference (EMI). The grounding electric resistance should be less than 1Ω, and the cross-sectional area of the PE conductor should be at least 2.5 mm² (12AWG). The AC socket should be installed near the equipment for easy access.
Cable Management Recommendations: To ensure optimal performance and longevity, specific guidelines for cabling are provided:
- Bend Radius: Power cords, communication cables, and flat cables should have a bend radius greater than five times their diameter (seven times for frequently bent/removed cables). Coaxial cables require a bend radius greater than seven times their diameter (ten times for frequently bent/removed cables). High-speed cables (e.g., SFP cables) should have a bend radius greater than five times their diameter (ten times for frequently bent/removed cables).
- Fiber Bend Radius: For optical fibers, the fiber tray diameter should be at least 25 times the fiber diameter. When moving optical fibers, the bend radius should be at least 20 times the fiber diameter, and during cabling, it should be at least 10 times the fiber diameter.
- Bundling: Cables should be neatly bundled and marked with labels. Different cable types (power, signal, grounding) should be separated, maintaining a space of at least 30 mm when parallel. Binding racks and cabling slots should be smooth, without sharp corners. Proper buckles should be used, and excess buckle material should be trimmed smoothly. Cables should not be bundled within bend areas to prevent stress on cable cores.
- Fastening: When using screw threads to fasten cable terminals, bolts or screws must be tightly fastened, and anti-loosening measures should be taken. The hard power cable should be fastened by the terminal connection area to prevent stress. Self-tapping screws should not be used for fastening terminals.
Reset Functionality: The router includes a reset button on the front panel. A short press (less than 2 seconds) will restart the system. Pressing and holding the button for more than 5 seconds until the system status LED blinks will restore the device to its factory settings and restart it. After a factory reset, the default management address is http://192.168.110.1. This feature is useful for troubleshooting or reconfiguring the device from a clean state.
Heat Dissipation: The RG-EG210G-E employs natural heat dissipation, ensuring normal function without active cooling components. To facilitate proper air circulation, a minimum of 10 cm of clear space should be reserved on both sides and the back plane of the cabinet or device location. This ensures efficient heat escape and prevents overheating, contributing to the device's reliability and lifespan.
