Chapter 3 Installation Preparation
3.1 Precautions
To avoid any device impairment and bodily injury due to improper use, please follow the precautions listed below:
Before cleaning the switch, please unplug the switch connector first. Do not clean the switch with wet cloth or with liquid.
Do not place the switch near water or any damp area. Try as much as possible to prevent water and moisture from entering
the switch chassis.
Do not place the switch on the unstable cases or desktop, as the switch might be damaged severely in case of a fall.
Ensure proper ventilation of the room and keep the switch ventilation hole free of obstruction.
The switch can operate normally under correct voltage input. Make sure that the operating voltage is consistent with that
labeled on the switch.
Do not open the chassis while the switch is in operation to protect the safe of the operator and the switch.
3.2 Requirements on Environment
Switch should be used indoors. The following requirements must be met irrespective of whether you install the switch in 19-inch
standard cabinet or install it directly on the workbench.
Make sure that enough room is left for the ventilation hole of the switch so as to ensure the heat dissipation of the switch
chassis.
Make sure that the drafting and heat dissipation systems of the cabinet and the workbench are good.
Make sure that the cabinet and the workbench are stable enough to bear the weight of the switch and the accessories.
Make sure that the cabinet and the workbench are well grounded.
To ensure normal operation and prolong the service life of the switch, the requirements on the installation site described in the
following sections must also be met.

STCS4012 Series Layer 3 Switch Installation Guide
- - 8 - - www.stephen-tele.com
3.2.1 Temperature/Humidity Requirements
To ensure the normal operation and service life of a switch, you need to maintain the temperature and the humidity of the
equipment room at a certain level. If the humidity level in the equipment room is too high for a long time, it will lead to bad
insulation of the insulating material or even leakage. Sometimes, the mechanical performance, change of material and the
corrosion of some metal parts are also likely to occur. If the relative humidity is too low, the captive screw may become loose
due to the shrinking of insulating sheath. Meanwhile, the static electricity is likely to be produced in the dry weather, which may
jeopardize the CMOS circuit of the switch. The Higher the temperature is, the greater the damage to the switch will be. The
reliability of the switch will be then seriously affected and its service span will be shortened because of exposure to
high-temperature environment for a long term. The ultra-high temperature will speed up the aging process of the insulating
material.
3.2.2 Laser Safety
In operating status, it is prohibited to stare into the open optical interface because the laser being transmitted through the
optical fiber will produces a small beam of light, it has very high power density and is invisible to human eyes, when a beam of
light enters the eye, retinal may be burned.
֠
֠֠
֠Caution:
Staring at the laser beam inside the fiber could hurt your eyes.

Chapter 4 Installation
4.1 Hardware Installation
4.1.1 Installing the Switch in 19-inch Standard Cabinet
Take the following steps to install the switch:
Step 1: Check the grounding and stability of the cabinet. Attach the angle iron at both sides of the front or rear panel with screws.
Step 2: Place Switch on a shelf of the cabinet. In accordance with the actual cases, slide switch along the guiding slots of the
cabinet to an appropriate position. Ensure that there is proper clearance between the Switch and the guides.
Step 3: Use screws to attach the angle iron on the fixed cable guides at both sides of the cabinet. Make sure that switch is
securely mounted on the cabinet with the brackets of cabinet slots and the mounting angle iron of the switch.
4.1.2 Installing the switch on the Workbench
If 19-inch standard cabinet is not available, you may simply place the switch on a clean workbench. However, you need to pay
attention to the followings during such operation:
Make sure that the workbench is stable and well grounded.
Leave about 10 centimeters away from the four sides of the switch for heat dissipation.
Do not place heavy objects on top of the switch.
4.2 Connecting Power Cord
Step 1: Connect one end of the ground wire of the chassis shipped with the switch to the grounding screw on the switch rear
panel, and properly ground the other end as near as possible.
Step 2: Plug one end of the power cord to the power socket on the rear panel of the switch chassis, and plug the other end into
the socket of AC power supply.
Step 3: Check whether the power indicator (POWER) on the front panel of the switch is on. On means that the power cord is
correctly connected.

1 RTS ← 7
2 DTR ← 4
3 TXD ← 3
4 CD → 1
5 GND - 5
6 RXD → 2
7 DSR → 6
8 CTS → 8
II. Connecting Console Cable
While configuring the switch at the configuration terminal, take the following steps to connect the console cable.
Step 1: Plug the console cable’s DB-9 female connector to the serial port of the PC or the terminal where the switch is to be
configured.
Step 2: Plug one end of the RJ-45 connector of the console cable into the console port of the switch.
֠
֠֠
֠Caution:
Confirm the interface identification before plugging the connector into it


Note:
PC and terminal serial port doesn’t support hot swap. When connect the PC and switch, please
first plug the DB-9 female plug of the console cable to the serial port of the PC or the terminal,
then plug the RJ-45 connector of the console cable to the console port of the switch. When
disconnect the PC and switch, please first unplug the RJ-45 connector of the console cable to the
console port of the switch, then unplug the DB-9 female plug of the console cable to the serial

II. Connecting AUX cable
Step 1 : plug one end of the cross Ethernet cable into the AUX port of the switch.
Step 2 : plug the other end of the cross Ethernet cable into the Ethernet port of the PC.
4.5 Post-installation Checklist
After the installation is completed, check whether:
The power to be used is consistent with that labeled on the switch.
The Console cable and power input cable are connected properly.
Check if all the interface cabling is performed indoors and there is no outdoor cabling. In the case of outdoor cabling, check
if the socket strip with lightning protection and network port lightning arrester have been connected.
