followed can result in data loss, data corruption, or damage to hardware or software.
General safety recommendations
•
Keep the device and installation tools away from walk areas.
•
Place the device in a dry and flat location and make sure anti-slip measures are in place.
•
Remove all external interface cables and power cords before moving the device.
Electricity safety
•
Locate the power-off switch in the equipment room before installation. Shut off the power
immediately if an accident occurs. Disconnect the power cord from the device if necessary.
•
Make sure the device is reliably grounded.
•
Connect the interface cables correctly.
•

•
Always make sure the power has been disconnected during the installation or replacement
procedure.
Examining the installation site
The device can only be used indoors. To ensure correct operation and long service life of your
device, make sure the installation site meets the following requirements.

1-2
Temperature and humidity
Maintain the temperature and humidity in the equipment room as described in Table1-2.
•
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the device.
•
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 bring issues
including loose screws and circuit failure.
Table1-2 Temperature and humidity requirements
Temperature Humidity
•Operating: 0°C to 45°C (32°F to 113°F)
•Storage: –40°C to +70°C (–40°F to +158°F) 5% RH to 95% RH, 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.

on the peer end, respectively.
To connect an optical fiber for a fiber port:
1. Pivot the bail latch of the transceiver module up so that it catches a knob on the top of the
transceiver module.
2. Holding both sides of the transceiver module, insert the transceiver module slowly into the
port.
3. 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.
4. Examine the port LEDs:
If the LED is on, a fiber link has been set up.
If the LED is off, no link has been set up. The reason might be wrong connection of the Tx
and Rx ends. Swap the fibers in the Tx and Rx ports at one end.
