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.
• Move the switch carefully.
