2. Preparing for installation
2.1 Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, read the
following safety recommendations before installation. Note that the recommendations do
not cover every possible hazardous condition.
Regarding with installation and maintenance of this product, please make the engineer who
acquired a right operating method to do that.
Remove dust on and around the Switch regularly.
Before cleaning the switch, unplug all power cords from the switch. Do not clean the
switch with wet cloth or liquid.
Before moving the Switch, unplug all power cords from the switch.
Do not place the switch near water or in a damp environment. Prevent water or
moisture from entering the switch chassis.
Do not place the switch on an unstable case or desk. The switch might be severely
damaged in case of a fall.
Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents
of the switch free of obstruction.
Connect the yellow-green protection grounding cable before power-on.
Make sure the operating voltage is in the required range.
Please don't open equipment. Breakdowns when opening, will be applying of the
guarantee.
When replacing FRUs, including power modules and fan trays, wear an
ESD-preventive wrist strap to avoid damaging the units.
Please be sure to do service operation of the equipment which is being used after a
power supply is off.
Please put dustproof cover on the port where SFP/SFP+/QSFP+ transceiver module
isn't mounted.
2.2 Connecting the RJ45 connector

NOTE:
When connecting the RJ45 cable, wear a wrist strap to protect against static electricity.
Do not touch the RJ45 Ethernet cable terminal. If you touch the RJ45 Ethernet cable
terminal which is connecting to the Switch, the interface circuit may be broken by the static
electricity. When you connect the Console cable, you need also a same care.

2.3 Examining the installation site
The QX-S5500G Series switches must be used indoors.
You can mount your switch in a rack, or on a workbench, and make sure:
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
The rack, or on the workbench have a good ventilation system.
Identify the hot aisle and cold aisle at the installation site, and make sure ambient air
flows into the switch from the cold aisle and exhausts to the hot aisle.
Identify the airflow designs of neighboring devices, and prevent hot air flowing out of
the bottom device from entering the top device.
The rack, or the workbench are sturdy enough to support the switch and its
accessories.
The rack is well earthed.
To ensure normal operation and long service life of your switch, install it in an environment
that meets the requirements described in the following subsections.
2.3.1 Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
Lasting high relative humidity can cause poor insulation, electricity creepage,
mechanical property change of materials, and metal corrosion.
Lasting low relative humidity can cause washer contraction and ESD and bring
problems including loose captive screws and circuit failure.
High temperature can accelerate the aging of insulation materials and significantly
lower the reliability and lifespan of the switch.
For the temperature and humidity requirements of different switch models, see "Technical
specifications" of “Chapter 1 Product overview”.

2.3.2 Cleanness
Dust buildup on the chassis may result in electrostatic adsorption, which causes poor
contact of metal components and contact points, especially when indoor relative humidity is
low. In the worst case, electrostatic adsorption can cause communication failure.
Table 2-1 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m³)
Dust
≤ 3 x 104 (no visible dust on the tabletop over three days)
Note:
Dust diameter ≥ 5 μm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate
corrosion and premature aging of components, as shown in Table 2-2

2.3.3 EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and
application system, adversely affect the switch in a conduction pattern of capacitance
coupling, inductance coupling, electromagnetic wave radiation, or common impedance
(including the grounding system) coupling. To prevent EMI, take the following actions:
Please take the effective measures to reduce the intervention the power supply
system exerts on the switch.
Keep the switch far away from high-power radio launchers, radars, and equipment
with high frequency or high current.
If AC power is used, use a single-phase three-wire power receptacle with protection
earth (PE) to filter interference from the power grid.
Keep the switch far away from radio transmitting stations, radar stations, and
high-frequency devices.
Use electromagnetic shielding, for example, shielded interface cables, when
necessary.
Route interface cables only indoors to prevent signal ports from getting damaged by
overvoltage or overcurrent caused by lightning strikes.
2.3.4 Laser safety
The QX-S5500G Series switches are Class 1 laser devices.
