Electricity safety
•
Locate the emergency power-off switch in the room before installation. Shut the power off at once in
case accident occurs. Disconnect the power cord of the router if necessary.
•
Use an uninterrupted power supply (UPS).
•
Do not work alone when the router has power. Do not touch any power plug when it is connected.
•
Always make sure the power has been disconnected during the installation and replacement.
Laser safety
WARNING!
•
Do not stare into any fiber port when the router has power. The laser light emitted from the optical fiber
might hurt your eyes.
•
Use 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.
The routers are Class 1 laser devices.
When you connect an optical fiber, follow these guidelines:
•
Some interface modules on the router provide shielded covers for the fiber ports (such as SFP ports).
Before using such fiber ports, remove the shielded covers. Keep the shielded covers secure. When
the fiber ports are not in use, install the shielded covers.
•
Fiber connectors are fitted with dust caps. Keep the dust caps secure when the fiber connectors are
in use. Install dust caps when the fiber connectors are not in use to avoid damage to their end face.
Replace the dust cap if it is loose or polluted.
