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.

•Before connecting an optical fiber, use dust free paper and absolute alcohol to clean the end face of the two fiber connectors. You can brush the end faces only in one direction.

•After a fiber is installed well, the bend radius must be not less than 10 cm (3.94 in).

•If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted surface. (The filleting radius must be not less than 2 mm, or 0.08 in.) When passing through a metallic board hole or bending along the acute side of mechanical parts, the fiber must wear jackets or cushions.

Router moving

WARNING!

Do not hold the handle of the fan tray or power supply, the handle of the rear cover of the chassis, or the air vents of chassis. Any attempt to carry the router with these parts might cause equipment damage or even bodily injury.

When you move a router, follow these guidelines:

•Lift and put down the chassis slowly and never move suddenly.

•When you move a heavy router or multiple routers, use a pallet jack.

•Before moving the chassis, turn off the power switch and remove all cables, USB devices, and mounting brackets.
