1 Product Overview
The RSR20-X-28 series routers are data communication products independently developed by Ruijie Networks Co. Ltd.
by using advanced semiconductor technologies and communication control technologies. Ruijie series routers are
developed in full compliance with international standards, therefore, it is similar to major routers in terms of use and
configuration approach. Network administrators who are familiar with the configuration commands of major routers may
use the routers without receiving training first.
1.1 About the RG-RSR20-X-28
Developed from Ruijie’s RSR (Reliable multi-Services Router), RSR20-X-28, as the next generation access router, is
characterized by its applicability in a variety of access scenarios, such as routing, switching, security, 3G/4G and WiFi.
With improvements in performance, port number, rate and reliability, RSR20-X-28 offers integrated solutions for
enterprise edge networks at minimum costs. The Router provides a consolidated service infrastructure that enables
scalable deployment of new applications to better address the diversified demands for future business development.
RSR20-X-28 is an ideal choice for branch offices of medium and large-sized financial institutions, governments or
enterprises to access multiple services in a cost-efficient way.
Adopting advanced RGOS operation system, RSR20-X-28 supports Ruijie’s patented technologies REF (Ruijie
Express Forwarding), VCPU (virtual CPU) and X-Flow. All these leading technologies guarantee stable forwarding
even when multiple services are enabled on the Router. Because of Stateful Firewall, RSR20-X-28 is good at resisting
flow attacks. The Router delivers plentiful backup solutions, QoS/HQoS characteristics, service-rich features, including
MPLS, VPN, multicast, IPv6, VoIP, NAT and MVRF. In this manner, users do not need to purchase additional software
Licenses or service modules.
Supporting HSIC service modules, RSR20-X-28 totally delivers up to 10Gbps bandwidth. The Router also supports
expansion of 10G Ethernet interface modules and other WAN and LAN modules of diverse types, multiple functions
and high intensity. Such expandability serves as a foundation for more combination possibilities. Plugging and
unplugging of hot-swappable HSIC service modules have no influence on forwarding services of other operating
modules. Plus, RSR20-X-28 supports alternating/direct current power supply redundancy, which helps enhance
reliability.
Aimed at offering users simplistic and efficient network, RSR20-X-28 supports simplistic network solutions, including
device virtualization, WAN port aggregation, IDA and ITO.
Different SIC slots support different extension service modules to flexibly meet users’requirements.

without OFL buttons are not hot-swappable. HSIC-2E1/CE1 and HSIC-2HS support hot swapping. HSIC-4G-LTE
does not support hot swapping.
Up to two power supply modules are supported. Slot 4 and Slot 5 support power supply modules. Hot swapping is
supported.
Up to two DHSIC modules are supported. Modules with OFL buttons are hot-swappable, while modules without
OFL buttons are not hot-swappable.

FUNC Button Image
Figure 1-8 FUNC Button
The FUNC button is close to the SD card slot on the front panel. It is used for one-click upgrade. To avoid careless
touching, the button is designed to be pressed using a tiny needle.

Features
When an SD card or a USB flash disk is inserted into the device, press the FUNC button. Then, the system searches
for the installation packages and configuration files that are applicable to the current device in the root directories of the
SD card and USB flash disk in sequence. After successfully finding the corresponding installation packages and
configuration files, the system checks the validity of the files and then upgrades the device by using the installation
packages and configuration files. After the upgrade, the system resets and restarts based on the new software versions
and configuration files.
When NO SD card or a USB flash disk is inserted into the device, press the FUNC button to reset the system.
When a storage medium is inserted, the system scans for an SD card first. If no SD card is inserted or the inserted
SD card does not contain applicable installation packages or configuration files, the system scans for a USB flash
drive. If neither the inserted SD card nor the USB flash drive contains applicable installation packages or
configuration files, the software versions and configuration files are not upgraded. Only the system resets, and
restarts based on the original software versions and configuration files.
One-click upgrade of the software version must strictly follow the “Configuring Reliability” chapter in the related
software configuration guide. After the system has scanned an SD card or USB flash drive, press the FUNC
button shortly.
