1Product Overview
RG-N18000-XH series switches are Ruijie-developed next-generation core switches. Based on matrix separation, they
use the Clos architecture and support a large buffer. They support dual supervisor modules and redundancy of power
modules, switch fabric modules, and fan modules.
The RG-N18018-XH: has 18 transverse slots, and provides dual supervisor modules, 16 line card slots, 20 power
modules, eight switch fabric modules, and three fan modules.
The RG-N18010-XH: has 10 transverse slots, supports dual supervisor modules, eight line card slots, ten power

The RG-N18000-XH series switch is a class-A product. In a domestic environment, this product may cause radio
interference in which case the user may be required to take adequate measures.
The switch is connected to the specified uninterruptible power supply (UPS) instead of the DC power grid. DC
tolerance: 188 V DC to 400 V DC.
This equipment is not suitable for use in locations where children are likely to be present.
This equipment is restricted to use in the machine room by the professional personal or maintainer.
All power cords need to be removed after power-off. For security concerns, shut down the chassis and then unplug
the power cord.
Be cautious of electric shock hazard. The fuse is in the neutral wire. Therefore, cut off the power supply to power
off phase conductors.
Product Appearance
The RG-N18018-XH is composed of the chassis, power system, modules, and heat dissipation system.
The power system provides 20 power module slots and supports power modules in N+1 redundancy mode. You are
advised to configure redundancy for power modules.
The RG-N18018-XH provides two supervisor module slots, 16 line card slots, and eight switch fabric module slots.
The supervisor modules support 1+1 redundancy. You are advised to configure redundancy for the supervisor
modules. You can select different line cards as needed.
The cooling system provides three fan modules on the rear of chassis. M18018XH-FAN supports fan redundancy.

Ensure that the supervisor module, line card, switch fabric module, and power module are removed from the
chassis before you move or transport the RG-N18018-XH chassis.
The chassis has two toggle switches in redundancy mode. If both switches are off, the power supply is disabled. If
either switch is on, the power supply is enabled.

Power Supply
The RG-N18018-XH adopts both AC and DC power supply input: AC power supply input: The RG-PAH3000I-F power module
is supported. This power module supports power management. The supervisor module of the RG-N18018-XH can read
power supply information and implement flexible and intelligent power management. The RG-PAH3000I-F power module
has dual power inputs (AC+AC, HVDC+HVDC, or AC+HVDC).
When both power inputs meet the power supply requirement:
Adopt either power input in the case of AC + AC input.
Adopt either power input in the case of HVDC + HVDC input.
Adopt AC input in the case of AC + HVDC input (HVDC as the standby power input).

When only one power input meets the power supply requirement:
Adopt the AC input that meets the requirement in the case of AC + AC input.
Adopt the HVDC input that meets the requirement in the case of HVDC + HVDC input.
Adopt the AC or HVDC input that meets the requirement in the case of AC + HVDC input.
When an under-voltage or over-voltage occurs:
Switch over to the other power input channel if it meets the requirement.
Avoid switching over to the other power input channel if it does not meet the requirement. Instead, brownout is allowed.
When channel A restores while channel B is suppling power:
Switch over to channel A if it meets the requirement.
Avoid switching over to channel A if it does not meet the requirement. Instead, continue to use channel B.
The RG-N18018-XH supports dual power domains. To enhance overall stability and reliability, you are advised to
power on the power module through dual power domains.
Heat Dissipation System
The operating environment temperature of the RG-N18018-XH ranges between 0°C (32°F) and 40°C (104°F). The thermal
design must satisfy the requirement on the device's reliability in the temperature range while ensuring the device's safety
and maintainability. The RG-N18018-XH uses fans to draw air for forced convection cooling, ensuring that the device
works properly in the specified environment.
