General safety recommendations
• Take adequate safety measures to avoid injury and switch damage. For example, wear an
ESD-preventive wrist strap.
Make sure that the ground is dry and flat and anti-slip measures are in place.
•
Keep the chassis clean and dust-free.
•
Do not place the switch on a moist area and avoid liquid surrounding the switch.
•
Keep the chassis and installation tools away from walk areas.
•
• Move the switch and heavy components (such as the power supplies or chassis) with other people
rather than doing that alone.
Safety with electricity
Clear the work area of possible hazards, such as ungrounded power extension cables, missing
•
safety grounds, and wet floors.
• Locate the emergency power-off switch in the room before installation. Shut the power off at once in
case accident occurs.
Unplug all the external cables (including power cables) before moving the chassis.
•
• Do not work alone when the switch has power.
Always check that the power has been disconnected.
