Chapter 2 Installation Preparation
2.1 Cautions
Similar to other electronic products, the semiconductor chip easily gets damaged if you
power on and off abruptly and frequently. To restart up the router of TSR 2800-20-DC,
you have to open the power on-off after the power is cut down for three to five
seconds.
Avoid severe collision or falling down from the height to protect the parts in the router.
Use correct outside ports to connect the router of TSR 2800-20-DC. Do not insert the
telephone plug (4-line RJ11 plug) into the Ethernet twisted-pair port or the console port
(RJ45 8-line socket); do not insert the Ethernet twisted-pair plug into the console port.
Similarly, do not insert the console cable into the Ethernet twisted-pair port (RJ45
8-line socket).
Note:
1) When you plug or dial out the power line, keep the power line horizontal with the
power socket.
2) When the lifetime of our products ends, handle them according to national laws
and regulations, or send these products to our company for collective processing.
2.2 Safety Advice
Safety Principles
zKeep dustless and clean during or after the installation.
zPut the cover at the safe place.
zPut tools at the right place where they are not easily falling down.
zPut on relatively tight clothes, fasten the tie or scarf well and roll up the sleeve,
avoiding stumbling the chassis.
zPut on the protective glasses if the environment may cause damage to your

Electrostatic Discharge Prevention
Electrostatic discharge may damage devices and circuits. Improper treatment may
cause the router to malfunction completely or discontinuously.
Move or locate the devices according to the measures of electrostatic discharge
prevention, ensuring the chassis connects the ground. Another measure is to wear the
static-proof hand ring. If there is no hand ring, use the metal clip with the metal cable to
clip the unpainted metal part of the chassis. In this case, the static is discharged to the
ground through the metal cable of the clip. You can also discharge the static to the
ground through your body.
2.3 Requirements for Common Locations
This part describes the requirements for the installation locations.
2.3.1 Environment
The router can be installed on the desk or the cabinet. The location of the chassis,
cabinet planning and indoor cabling are very important for normal system’s function.
Short distance between devices, bad ventilation and untouchable control plate will
cause maintenance problems, systematic faulty and breakdown.
For location planning and device locating, refer to section 2.3.2 “Location Configuration
Prevention”.
2.3.2 Location Configuration Prevention
The following preventive measures assist you to design the proper environment for the
router.
zMake sure that the workshop is well-ventilated, the heat of TX devices is
well-discharged and sufficient air circulation is provided for device cooling.
zAvoid to damage devices by following the electrostatic discharge prevention
procedure.
zPut the chassis at the place where cool air can blow off the heat inside the
chassis. Make sure the chassis is sealed because the opened chassis will
reverse the cool air flow.
2.3.3 Cabinet Configuration
The following content assists you to make a proper cabinet configuration:
zEach device on the cabinet gives off heat when it runs. Therefore, the sealed
cabinet must have the heat-discharge outlet and the cooling fan. Do not put the
devices too close, avoiding bad ventilation.
zWhen you install the machine box at the open cabinet, prevent the frame of the
cabinet from blocking the airway of the machine box.

TSR 2800-20-DC Router’s Hardware Installation Manual
- 8 -
zEnsure that nice ventilation is provided for the devices installed at the bottom of
the cabinet.
zThe clapboard separates exhaust gas and inflow air, and boost the cool air to
flow in the chassis. The best location of the clapboard is decided by the air flow
mode in the chassis, which can be obtained through different location tests.
2.3.4 Power Requirements
Make sure that the power supply has nice grounding and the power at the input side of
the router is reliable. The voltage control can be installed if necessary. At least a 240 V
and 10A fuse or a breaker is provided in the phase line if you prepare the short-circuit
prevention measures for a building.
Caution:
If the power supply system does not have good grounding, or the input power disturbs
too much and excessive pulses exist, the error code rate of communication devices
increases and even the hardware system will be damaged.
2.4 Installation Tools and Device
The tools and devices to install the router are not provided. You need to prepare them
yourself. The following are the tools and devices needed for the typical installation of
the router:
zScrewdriver
zStatic armguard
zBolt
zCable for LAN connecting WAN
zHUB or PC with Ethernet card
zControl terminal
zMODEM
