NOTE:
The available chassis models and accessories vary by country and region. This document describes
only the preceding models. For the chassis models and accessories available in your country or
region, contact the local H3C marketing personnel.
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.
Before cleaning the switch, remove all power cords from the switch. Do not clean the switch
with wet cloth or liquid.
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 good ventilation of the equipment room and keep the air inlet and outlet vents of the
switch free of obstruction.
1-2
Make sure the power input voltage is as required by the power module.
To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
During switch installation, wear an ESD wrist strap. Make sure the strap makes good skin
contact and is reliably grounded.
Examining the installation site
The switch must be used indoors. You can mount your switch in a rack or on a workbench. Make sure
the following requirements are met:
Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
The rack or workbench has 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
neighboring device from entering the device.
The rack is sturdy enough to support the switch and its accessories.
The rack or workbench is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.
Temperature/humidity
Maintain temperature and humidity in the equipment room as described in "Appendix A Chassis
views and technical specifications."
Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose mounting 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"
Cleanliness
Dust buildup on the chassis might 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 1-1 Dust concentration limit in the equipment room

system, adversely affect the switch in the following ways:
A conduction pattern of capacitance coupling.
Inductance coupling.
Electromagnetic wave radiation.
Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
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.
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.
Laser safety
WARNING!
The switch is Class 1 laser device. Disconnected optical fibers or transceiver modules might emit
invisible laser light. Do not stare into beams or view directly with optical instruments when the switch
is operating.

Grounding the switch
WARNING!
Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. For
information about lightning protection for the switch, see H3C Lightning Protection Guide.
The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this
chassis ground to the earth to minimize the potential for system damage, maximize the safety at the
site, and minimize EMI susceptibility of the system.
NOTE:
The power and grounding terminals in this section are for illustration only.
Grounding the switch with a grounding strip
CAUTION:
Connect the grounding cable to the grounding strip in the equipment room. Do not connect it to a
fire main or lightning rod.
To guarantee the grounding effect and avoid switch damage, use the grounding cable provided
with the switch to connect the switch to a grounding strip in the equipment room.
If a grounding strip is available at the installation site, use the grounding cable provided with the
switch to connect the switch to the grounding strip.
Connecting the grounding cable to the chassis
1. Remove the grounding screw from the grounding hole in the rear panel of the switch chassis.
2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
screw hole. Fasten the screw.
IMPORTANT:
Orient the grounding cable as shown in Figure 2-10 so that you can easily install
or remove the
removable components.

the earth ground
If the installation site does not have any grounding strips, but earth ground is available, hammer a 0.5
m (1.64 ft) or longer angle iron or steel tube into the earth ground to serve as a grounding conductor.
The dimensions of the angle iron must be a minimum of 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The
steel tube must be zinc-coated and its wall thickness must be a minimum of 3.5 mm (0.14 in).

Installing and removing a fan tray
CAUTION:
You can power on the switch only when the switch has two fan trays of the same model installed.
Do not leave any slots empty when the switch is operating. Install a module or filler panel in the
slots.
If both fan trays fail while the switch is operating, replace them within 2 minutes.
If one fan tray fails while the switch is operating, perform either of the following tasks:
{ If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24 hours and
make sure the failed fan tray is in position before the replacement.
{ If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
If you power cycle the switch after a fan tray fails, the switch will fail to start up.
The switch comes with empty fan tray slots. It supports the LSWM1FANSCE and LSWM1FANSCBE
fan trays.
The LSWM1FANSCE fan tray provides power module-side intake and port- and chassis-side
exhaust airflows. The fan tray handle is blue.
The LSWM1FANSCBE fan tray provides port- and chassis-side intake and power module-side
exhaust airflows. The fan tray handle is red.
Select the LSWM1FANSCE or LSWM1FANSCBE fan trays for the switch based on the ventilation
requirements at the installation site.
Installing a fan tray
1. Wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably
grounded.
2. Unpack the fan tray and verify that the fan tray model is as required.

3. Orient the fan tray with the TOP mark facing up.
4. Align the fan tray with the fan tray slot. Holding the fan tray handles, slide the fan tray into the
slot along the guide rails. Make sure the fan tray is fully seated in the slot and has a firm contact
with the backplane.
To prevent damage to the fan tray or the connectors in the chassis, insert the fan tray gently. If
you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it
again.
Figure 2-13 Installing a fan tray
IMPORTANT:
At the first login to the switch, use the
fan prefer-direction command to set the airflow
direction of the switch to be the same as the airflow direction of the fan trays. If the fan trays have
a different airflow direction than the switch, the system outputs traps and logs to notify you to
replace the fan trays.
By default, the switch uses the same airflow direction (power-to-port) as the LSWM1FANSCBE
fan tray.
Removing a fan tray
WARNING!
To avoid bodily injury, disturbing the dynamic balance of the fan tray, and causing loud noises, do
not touch the rotation axis, or any bare wires, fan blades, or terminals on the fan tray.
Do not place the fan tray in a moist place. Prevent liquid from entering the fan tray.
Fan trays with faulty internal wiring and conductors require maintenance from maintenance
engineers. Do not disassemble the faulty fan trays.
To remove a fan tray:
1. Wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably
grounded.
2. Holding the fan tray handles, pull the fan tray slowly out of the slot along the guide rails.
3. Put the removed fan tray in an antistatic bag.
