Juniper Networks MX480 - Manual (Page 280)

To lift routing devices and components, use the following lifting guidelines:
• Up to 39.7 lbs (18 kg) 1 person lift.
• 39.7 lbs (18 kg) to 70.5 lbs (32 kg) 2 or more person lift.
• 70.5 lbs (32 kg) to 121.2 lbs (55 kg) 3 or more person lift.
• Above 121.2 lbs (55 kg) material handling systems (such as levers, slings, lifts and
so on) must be used. When this is not practical, specially-trained persons or systems
must be used (riggers or movers).
• Before lifting or moving the router, disconnect all external cables.
• As when lifting any heavy object, lift most of the weight with your legs rather than your
back. Keep your knees bent and your back relatively straight and avoid twisting your
body as you lift. Balance the load evenly and be sure that your footing is solid.

General Laser Safety Guidelines for Juniper Networks Devices
Devices with single-mode optical interfaces are equipped with laser transmitters, which
are considered a Class 1 Laser Product by the U.S. Food and Drug Administration, and
are evaluated as a Class 1 Laser Product according to EN 60825–1 +A11 +A2 requirements.
When working around devices with optical interfaces, observe the following safety
guidelines to prevent eye injury:
• Do not look into unterminated ports or at fibers that connect to unknown sources.
• Do not examine unterminated optical ports with optical instruments.
• Avoid direct exposure to the beam.
WARNING: Unterminated optical connectors can emit invisible laser
radiation. The lens in the human eye focuses all the laser power on the
retina, so focusing the eye directly on a laser source—even a low-power
laser—could permanently damage the eye.
