Installation Guide SX1000 SBC
1-2 New Rock Technologies, Inc.
High temperature acceralets aging of electrical parts and insulation materials.
Low temperature, however, may destablize the operation of the device.
1.2.2 Cleanliness
Dust is very harmful to the safe operation of the device. Dust that is adsorbed by static electricity acts as
insulator, which not only affects the service life of the device but also leads to communication failure.
Therefore, the room for the device must be kept clean.
To ensure adequate ventilation to keep the device from overheating, there should be adequate clearance
for the air intake and the air exhaust vents. Keep at least 6 cm clearance at the left and right side of the
chassis where the air intake is and at least 15 cm clearance at the rear of the chassis where the exhaust
vents located.
The rack for SX1000 should have a good ventilation system.
1.2.3 Grounding
To maintain good voice quality, proper grounding of the AC supply is critical to minimize the noise from
the AC interference. Therefore, the following conditions must be ensured:
The AC power outlet has a protection ground contact.
The ground contact of AC supplier must be grounded properly.
Avoid sharing the multi-outlet power strip with other devices that may generate elctrical interference.
SX1000 is chassis based with ground tab. In a site that can provide ground for the chassis, the ground tab
at the rear panel of chassis for SX1000 must be properly grounded.
1.2.4 Electromagnetic Environment
Any possible interference source, wherever it is from, impacts the device negatively. To resist the
interference, make sure that:
Keep the device far from radio transimitting station, radar station, and high-freqency devices. Use
electromagnetic shielding when necessary.
The device is capable for secondary lighten protection on wires and cables that connected to outside
buildings.The site must provide the primary lighten protection.
The power supply system should be used independently as much as possible and effective measures of
preventing electric grid from interference should be adopted.
Ensure a good power grounding effect of equipment or add a lightning protector.
1.2.5 Other Facilities
Rack/Workbench
SX1000 is designed to be installed in a standard 19-inch rack, which should provide adequate air-flow to
cool down the device, and should be firm enough to support the weight of the device. It is also
recommended that the rack is earth grounded properly.
IP Network
SX1000 is connected to IP network through its 10/100 base-T Ethernet port and can communicate with
other equipments through the network. Inspect IP network on the site, including router, switch, cable
