Preparing for installation

Safety recommendations

To avoid possible bodily injury and equipment damage, read the safety recommendations in this chapter
carefully before installing an H3C S7508E-X switch. The recommendations do not cover every possible
hazardous condition.

General safety recommendations

• Keep the chassis clean and dust-free. Do not place the switch on a moist area and avoid liquid
flowing into the switch.
Make sure the ground is dry and flat and you have adopted anti-slip measures.
•
Keep the chassis and installation tools away from walk areas.
•
Do not wear loose clothing, jewelry (for example, necklace) or any other things that could get
•
caught in the chassis when you install and maintain the switch.

Electricity safety

Clear the work area of possible hazards, such as ungrounded power extension cables, missing
•
safety grounds, and moist 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.
•

Handling safety

CAUTION:
When moving the switch, hold the handles on the chassis.
•
Do not hold the handle of the fan tray, power module, or back cover of the chassis, or the air vents of
•
chassis. Any attempt to carry the switch with these parts may cause equipment damage or even bodily
injury.
To move an H3C S7508E-X switch, follow these steps:
Remove all the external cables (including the power cables) before moving the chassis.
•
Use at least two people to move the switch, and use a mechanical lift if necessary.
