Product Overview
Designed with the distributed modular structure, RG-RSR77 series routers have the high-processing capability and greater access
density and support the dual master control warm backup and power redundant backup to provide users with abundant optional
modules. RG-RSR77 series routers can serve as core routers in the large-scale enterprise networks or convergence layer routers in
the large-scale industry networks.
RG-RSR77 series routers adopt the high-performance microprocessor technology and use the network operating system platform of
proprietary intellectual property rights developed by Ruijie Networks Co. Ltd. RG-RSR77 series support the BGP routing protocol, IP
multicast protocol and high forwarding rate and offer abundant QoS features, providing the comprehensive network solutions for users
in the industry such as telecom, private network, ISP, finance, taxation, police and railway and users in large/medium-scale enterprise.
RG-RSR77 series includes three routers: RG-RSR7704, RG-RSR7708 and RG-RSR7716.
Safety Precautions for Movement
RG-RSR77 series routers are large and heavy. When you handle them, please pay attention to the following requirements:
Turn off all power supplies and unplug all power cables before you move the routers.
Plug out power, fan and service modules to reduce the chassis weight before moving the router.
At least two people are needed to move the router. Do not attempt to move the router by one person only. Keep balance when
moving the router.
Grasp the bottom the chassis. Do not grasp the power system handle, fan handle and the back panel handle when you carry the
chassis. Those handles are used to install and remove corresponding parts, and they are unable to bear the whole chassis
weight. For the RSR7708 and RSR7716, you can use the two handles at the top of the chassis to carry.
The whole router weight may be higher than 80Kg during the movement.
To correctly move the RG-RSR77 series router, see the Figures (Note: In order to avoid the chassis weight increase and the
service card damage, do not insert the service cards when you move the chassis.)

System Grounding
Grounding Requirements
An outstanding grounding system is the basis of stable and reliable operation of RG-RSR77 series router and the essential
condition for prevention of lightning and interference.
For the safety of humans and routers, good grounding is necessary for the router. The electric resistance between the router
chassis and the ground must be less than 0.1 ohm.
Grounding description
There are two kinds of ground in a machine room: safe ground and lightning prevention ground.
Safe ground guarantees the safety of humans and routers. A typical example is the AC protection ground of 3-core socket of
power supply bank.
Figure-4 3-core Socket of Power Supply Bank
Lightning prevention ground prevents lightning shock. The lightning prevention system of general equipment is a separate
system composed of lightning rod, down-conductor and grounding system.
Some machine room has only safe ground without lightning prevention ground or a safe ground sharing lightning prevention
ground.
Chassis grounding pole
There is a grounding pole on the rear of RG-RSR77 series router, as shown in the Figure-5.
