General safety recommendations
• Keep the chassis and installation tools away from walk areas.
• Make sure that the ground is dry and flat and anti-slip measures are in place.
• Unplug all the external cables (including power cables) before moving the chassis.
Safety with electricity
• Locate the emergency power-off switch in the room before installation. Shut the power off at once in
case accident occurs.
• Make sure that the router has been correctly grounded.
• Do not open or close the chassis cover when the router is powered on.
• Connect the interface cables for the router correctly.
• Use an uninterrupted power supply (UPS).
• If there are two power inputs, disconnect the two power inputs to power off the router.
• Do not work alone when the router has power.
• Always check that the power has been disconnected.
Safety with laser
• Do not stare into the optical port or fiber connector because the laser light emitted from the optical
fiber may hurt your eyes.
