Dusting Cycle Suggestions:
It is suggested to purchase an air filter and install it on the switch.
1. Clean the air filters every three months.
2. Dust the air intakes and exhaust vents of all modules every three months.
3. Dust the modules every one or two years.
4. Dust the fan shelves yearly.
5. Dust the chassis, including the backboard, every one or two years.
If the device is in a poor dust prevention environment, please increase the dusting times.
2.2.7 Power Requirements
When the RG-S7808C can use the following power supplies:
RG-PA1600I-F and RG-PA600I-F power modules adopt 90 to 264 VAC/ 47 to 63 Hz input.
Input power shall be larger than the actual power consumption of entire system. For example, the S7808C chassis is
installed with two M7800C-CM, two M7800C-48SFP4XS-EA and two M7800C-36GT12SFP4XS-EA modules. The
total power consumption of the device would be: 2 x 65W (M7800C-CM) + 2 x 101W (M7800C-48SFP4XS-EA) + 2 x
80W (M7800C-36GT12SFP4XS-EA) + 176W (reserved power consumption for the whole switch) = 668W. It is
recommended that you adopt one RG-PA1600I-F or two RG-PA600I-F modules.
The following table lists the power consumption of each module:

The RG-S7808C provides N+N redundancy of power supply. You are recommended to use multiple power supplies
for the equipment to ensure its continuous and stable operation by avoiding the impact of unexpected power failures
on the equipment.
When the dual power supply is applied, the type of the power supply should be identical.
2.2.8 System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-S7808C. It is the key to prevent
lightning stroke and resist interference. Please carefully check the grounding conditions on the installation site according
to the grounding requirements, and perform grounding properly as needed.
Safety Grounding
The equipment using AC power supply must be grounded by using the yellow/green safety grounding cable. Otherwise,
when the insulating resistance decreases the power supply and the enclosure in the equipment, electric shock may occur.
The building installation shall provide a means for connection to protective earth, and the equipment is to be
connected to that means.
