1.2.1 Networking of Residential Area for Broadband Ethernet Access
In the networking of residential area with broadband Ethernet access, STCS3526 Series Routing Switch is located in the residential
area center. It connects to Ethernet users via the L2 switches such as SPEED S2026 Switch. Its Uplink is connected to the core L3
switch through the GE extended module and thus connected to the MAN backbone.
1.2.2 Networking of Medium/Small Enterprise or Large Enterprise Branch
In the medium/small enterprises or the branches of large enterprises, STCS3526 Series Routing Switch can serve as the backbone
switch, which is connected to the head office or other branches through the router. As the enterprise or organization scale grows,
STCS3526 Routing Switch can provide the larger scale backbone by cascade.
1.2.3 Networking of Large Enterprise and Campus
In large-scale enterprise networks and campus networks, STCS3526 Series Routing Switches are located on the convergence layer
and connected to several L2 Ethernet switches such as SPEED S2026 Switch on the downlink and the backbone GE switch via the GE
extended port on the uplink. In this way, STCS3526 Series Routing Switches provide a complete enterprise networking solution,
which provides 1000M bandwidth to backbone and 100M bandwidth to desktop users.

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.
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

STCS3526 Series Layer 3 Switch User Guide
- - 15 - -
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.
3.3 Installation Tools
Phillips screwdriver
Flat-blade screwdriver
ESD-preventive wrist strap

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.
