Electricity safety
•
Locate the emergency power-off switch in the room before installation. Shut the power off at once
in case accident occurs.
•
Make sure the UTM device has been correctly grounded.
•
Use an uninterrupted power supply (UPS).
•
Do not work alone when the UTM device has power.
•
Always check that the power is off.
Laser safety
The UTM device is a Class 1 laser product.
WARNING!
•
Do not stare into any fiber port when the UTM device has power. The laser light emitted from the
optical fiber may hurt your eyes.
•
Use a fiber test equipment, rather than a microscope or magnifier to observe an operating fiber
connector or port when you test link connectivity or system parameters.
Handling safety
When you move the UTM device, follow these guidelines:
•
Remove all external cables, including the power cords, before moving the chassis.
•
Lift and put down the chassis slowly and never move suddenly.
•
When you move multiple UTM devices, use a pallet jack.
