Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury, read the following safety recommendations before
installation. Note that the recommendations do not cover every possible hazardous condition.
General safety recommendations
• Do not place the device on an unstable case or desk. The device might be severely damaged in
case of a fall.
• Make sure the ground is dry and flat and anti-slip measures are in place.
• Keep the chassis and installation tools away from walk areas.
• Keep the chassis clean and dust-free.
• Do not place the device near water or in a damp environment. Prevent water or moisture from
entering the device chassis.
• Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the device
free of obstruction.
• Make sure the device operates in the voltage range as required.
• Use a screwdriver to fasten screws.
• To prevent condensation, perform the following tasks:
{ Unpack the device a minimum of half an hour after you move the device from a location below
0°C (32°F) to the equipment room.
{ Power on the device a minimum of 2 hours after you move the device from a location below 0°C
(32°F) to the equipment room.
Electrical safety
• Carefully examine your work area for possible hazards, such as moist floors, ungrounded power
extension cables, or missing safety grounds.
• Locate the emergency power-off switch in the room before installation. Shut off the power
immediately if an accident occurs.
• Unplug all the external cables (including power cables) before moving the chassis.
• Do not work alone when the device has power.
• Always check that the power has been disconnected.
2
Laser safety
W
ARNING!
Do not stare into any fiber port when the device is powered on. The laser light emitted from the fiber por
t
might hurt your eyes.
• Before you disconnect a fiber connector, execute the shutdown command in interface view to
disable the optical source.
• After you remove an optical fiber from the connector, install the dust cover on the connector to avoid
connector damage.
Examining the installation site
The device can only be used indoors. To ensure correct operation and a long lifespan for your device, the
installation site must meet the requirements in this section.
Temperature and humidity
Maintain the temperature and humidity in the equipment room as described in Table 1.
• 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 cause problems including
loose screws and circuit failure.
• High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the device.
Table 1 Temperature/humidity requirements in the equipment room
Tem
p
erature Relative humidit
y
0°C to 40°C (32°F to 104°F) 5% to 95%, noncondensing
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.

The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 3.

Cooling
• Leave a minimum of 10 cm (3.94 in) of clearance around the device.
• A good ventilation system is available at the installation site.
ESD prevention
The device might be damaged by the following Electrostatic discharge (ESD) sources:
• Outdoor environment—For example, high-voltage power line and lightning.
• Indoor environment—For example, floor carpet.
• Device internal system.
To prevent ESD damage, follow these guidelines:
• Ground the device reliably.
• Take dust-proof measures for the equipment room. For more information, see "Cleanliness."
• Maintain the
humidity and temperature at acceptable levels. For more information, see
"Temperature and humidity."
• Wear an ESD suit and an ESD wrist strap, wear ESD gloves, and remove any electrically conducting
objects such as watch or jewelry before handling the device.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the device and application
system, adversely affect the device 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, perform the following tasks:
• 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 device far away from radio transmitting stations, radar stations, and high-frequency
devices.
4
• Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Lightning protection
To protect the device from lightning, follow these guidelines:
• Make sure the chassis is reliably grounded by using the grounding cable.
• Make sure the grounding terminal of the AC power receptacle is reliably grounded.
• Install a lightning protector at the power input end.

Grounding the device
W
ARNING!
• Correctly connecting the device grounding cable is crucial to lightning protection and EMI protection.
• Connect the grounding cable to the groundin
g
system in the equipment room. Do not connect it to a fire
main or lightning rod.
No grounding cable is provided with the device. Prepare a grounding cable yourself.
Attaching the ring terminal to the grounding cable
1. Cut the grounding cable as appropriate for connecting to the grounding strip.
2. Use a wire stripper to strip 5 mm (0.20 in) of insulation off the end of the grounding cable.
3. Slide the heat-shrink tubing onto the cable and insert the bare metal part into the end of the ring
terminal.
4. Use a crimper to secure the metal part of the cable to the ring terminal.
5. Slide the heat-shrink tubing down the cable until the tubing covers the joint.
6. Use a blow dryer to shrink the tubing around the cable.
8
Figure 3 Attaching the ring terminal to the grounding cable
Connecting the grounding cable to the device
1. Use a Phillips screwdriver to remove the grounding screw from the rear panel of chassis.
2. Use the grounding screw to attach the ring terminal of the grounding cable to the chassis.
3. Connect the other end of the grounding cable to the grounding strip.
Make sure the grounding strip has been reliably grounded.

Connecting the Ethernet cables
Connecting a copper Ethernet port
1. Connect one end of the Ethernet cable to the copper Ethernet port on the device, and the other end
to the Ethernet port on the peer device.
2. After powering on the device, examine the LEDs of the fixed copper Ethernet port.
For more information about the LED description, see "Appendix B LEDs."
Connecting a fiber port
No transceiver module is provided with the device. The device supports only LC-type fiber connectors. For
transceiver module specifications, see "Appendix A Chassis views and technical specifications."
F
ollow these guidelines when you connect an optical fiber:
• Never stare into an open fiber port, because invisible rays might be emitted from the fiber port.
• Install dust plugs in empty fiber ports.
• Never bend a fiber excessively. The bend radius should not be less than 10 cm (3.94 in).
• Make sure the Tx and Rx ports on a transceiver module are correctly connected.
To connect the device to the network through an optical fiber:
13
1. Remove the dust plug from the fiber port.
2. Remove the dust cover from the transceiver module, and insert the transceiver module into the fiber
port.
3. Remove the dust covers from the optical fiber connector.
4. Identify the Rx and Tx ports on the transceiver module. Use the optical fiber to connect the Rx port
and Tx port on the transceiver module to the Tx port and Rx port on the peer end, respectively.
5. Power on the device, and examine the fiber port LED:
{ If the LED is on, a fiber link is present.
{ If the LED is off, no link is present. Verify that the Tx and Rx ports are correctly connected.
Figure 11 Connecting an optical fiber
Connecting the power adapter
1. Make sure the device is reliably grounded.
2. Connect the power adapter to an AC power source.
3. Connect the DC power connector on the power adapter to the power adapter receptacle on the
front panel of the device.
