classified by source/destination IP addresses, source/destination MAC addresses, IP
protocols, TCP/UDP, IP precedence, time ranges and ToS. And various policies can
be conducted to forward the traffic. By implementing ACL policies, users can filter the
virus packets such as “Worm.Blaster”, “Worm.Sasser” and “Red Code” etc. S98XX
series switch also support IEEE802.1x port based access authentication, which can
be deployed with RADIUS, to ensure the port level security and block illegal users.
QoS
S98XX series switch fully support DiffServ Module. Users can specify a queue
bandwidth on each port. WRR/SP/SWRR scheduling is also supported. S98XX series
support the port security. Users can deploy trusted CoS, DSCP, IP precedence and
port priority. User can also modify packets‟ DSCP and COS values. The traffic can be
classified by port, VLAN, DSCP, IP precedence and ACL table. User can also modify
packets‟ DSCP and IP precedence values. Users can specify different bandwidths for
voice/data/video to customize different qualities of service.

Chapter 2 Hardware Installation
2.1 Installation Notice
To ensure the proper operation of S98XX series and your physical security,
please read carefully the following installation guide.
2.1.1 Environmental Requirements
The switch must be installed in a clean area. Otherwise, the switch may be
damaged by electrostatic adherence.
Maintain the temperature within 0 to 50 °C and the humidity within 5% to 95%,
non-condensing.
The switch must be put in a dry and cool place. Leave sufficient spacing around
the switch for good air circulation.
The switch must work in the right range of power input (AC power: 90 ~ 264V
(50Hz), DC power: -40 ~ -60V)
The switch must be well grounded in order to avoid ESD damage and physical
injury of people.
The switch should avoid the sunlight perpendicular incidence. Keep the switch
away from heat sources and strong electromagnetic interference sources.
The switch must be mounted to a standard 19‟‟ rack or placed on a clean level
desktop.
2.1.1.1 Dust and Particles
Dust is harmful to the safe operation of S98XX series. Dust can lead to
electrostatic adherence, especially likely under low relative humidity, causing poor
contact of metal connectors or contacts. Electrostatic adherence will result in not only
reduced product lifespan, but also increased chance of communication failures. The
recommended value for dust content and particle diameter in the site is shown below:

Table 2.1 Environmental Requirements: Dust
In addition, salt, acid and sulfide in the air are also harmful to the switch. Such
harmful gases will aggravate metal corrosion and the aging of some parts. The site
should avoid harmful gases, such as SO2, H2S, NO2, NH3and Cl2, etc. The table

2.1.1.2 Temperature and Humidity
Although the switch is designed to use 4 fans, the site should still maintain a
desirable temperature and humidity. High-humidity conditions can cause electrical
resistance degradation or even electric leakage, degradation of mechanical properties
and corrosion of internal components. Extreme low relative humidity may cause the
insulation spacer to contract, making the fastening screw insecure. Furthermore, in
dry environments, static electricity is liable to be produced and cause harm to internal
circuits. Temperature extremes can cause reduced reliability and premature aging of
insulation materials, thus reducing the switch‟s working lifespan. In the hot summer, it
is recommended to use air-conditioners to cool down the site. And the cold winter, it is
recommenced to use heaters.
The recommended temperature and humidity are shown below:

Table 2.3 Environmental Requirements: Temperature and Humidity
Caution!
A sample of ambient temperature and humidity should be taken at 1.5m above
the floor and 0.4m in front of the switch rack, with no protective panel covering the
front and rear of the rack. Short term working conditions refer to a maximum of 48
hours of continued operation and an annual cumulative total of less than 15 days.
Formidable operation conditions refers to the ambient temperature and relative
humidity value that may occur during an air-conditioning system failure, and normal
operation conditions should be recovered within 5 hours.

2.1.1.3 Power Supply
Before powering on the power supply, please check the power input to ensure
proper grounding of the power supply system. The input source for the switch should
be reliable and secure; a voltage adaptor can be used if necessary. The building‟s
circuit protection system should include in the circuit a fuse or circuit-breaker of no
greater than 240 V, 10 A. It is recommended to use a UPS for more reliable power
supplying. .
Caution!
Improper power supply system grounding, extreme fluctuation of the input source,
and transients (or spikes) can result in larger error rate, or even hardware damage!
2.1.1.4 Preventing Electrostatic Discharge Damage
Static electric discharges can cause damage to internal circuits, even the entire
switch. Follow these guidelines for avoiding ESD damage:
Ensure proper earth grounding of the device;
Perform regular cleaning to reduce dust;
Maintain proper temperature and humidity;
Always wear an ESD wrist strap and antistatic uniform when in contact with circuit
boards.
2.1.1.5 Anti-interference
All sources of interference, whether from the device/system itself or the outside
environment, will affect operations in various ways, such as capacitive coupling,
inductive coupling, electromagnetic radiation, common impedance (including the
grounding system) and cables/lines (power cables, signal lines, and output lines). The
following should be noted:
Precautions should be taken to prevent power source interruptions;
Provide the system with a dedicated grounding, rather than sharing the grounding
with the electronic equipment or lightning protection devices;
Keep away from high power radio transmitters, radar transmitters, and high
frequency strong circuit devices;
Provide electromagnetic shielding if necessary.
2.1.1.6 Rack Configuration
The dimensions of the S98XX series is designed to be mounted on a standard
19‟‟ rack, please ensure good ventilation for the rack.
Every device in the rack will generate heat during operation, therefore vent and
