Preparing for installation

Safety recommendations

To avoid bodily injury and damage to the router, read all safety recommendations including the
compliance and safety manual for the router carefully before installation. Note that the
recommendations do not cover every possible hazardous condition.

General safety recommendations

•
Keep the chassis clean and dust-free.
•
Do not place the router on a moist area, and avoid liquid flowing into the router.
•
Make sure the ground is dry and flat and anti-slip measures are in place.
•
Ensure good ventilation in the equipment room and keep the air inlet and outlet vents of the
router free of obstruction.
•
When servicing the device, do not wear loose clothing or any other things that could get caught
in the chassis and remove all metal jewelry such as watches, bracelets, and necklaces.
•
Use a screwdriver to fasten screws.
•
After completing the installation, move the empty packaging materials and installation tools
away from the router.
•
Keep the chassis and installation tools away from walk areas.

Electricity safety

•
Clear the work area of possible electricity hazards, such as ungrounded power extension
cables, missing safety grounds, and wet floors.
•
Locate the emergency power-off switch in the room before installation so you can quickly shut
power off when an electrical accident occurs.
•
Remove all external cables, including power cords, before moving the chassis.
•
Do not work alone when servicing the router with power present.
•
Never assume that power has been disconnected from a circuit. Always check.

Moving safety

WARNING!
Hold the chassis handles firmly to move the router.
CAUTION:
Do not hold air vents of the chassis, the handle of a fan tray or power supply, or an ejector lever of a
module to move the router. Doing so might cause equipment damage.
The router is heavy and large. When you move the router, follow these guidelines:
•
Remove all external cables (including power cords), modules, and power supplies before
moving the chassis.
