■
When the equipment rack is mounted on a raised floor, ensure that the raised
floor has sufficient strength to withstand the weight upon it when the server is
extended on its slide rails. Fix the equipment rack through the raised floor to
the concrete floor below it, using a proprietary mounting kit for this purpose.
Caution – If more than one server is installed in an equipment rack, maintain the
servers one at a time.
For details of equipment racks, see the SPARC Enterprise Equipment Rack Mounting
Guide .
1.2.3 Component Handling Precautions
Caution – The server is easily damaged by static electricity. To prevent damage to
printed circuit boards, wear a wrist strap and connect it to the server prior to
starting maintenance.
Caution –
Do not bend the motherboard unit (MBU) or the components mounted
on circuit boards might be damaged.
To prevent the motherboard unit from being bent, observe the following precautions:
■
Hold the motherboard unit by the handle, where the board stiffener is located.
■
When removing the motherboard unit from the packaging, keep the motherboard
unit horizontal until you lay it on the cushioned conductive mat.
■
Connectors and components on the motherboard unit have thin pins that bend
easily. Therefore, do not place the motherboard unit on a hard surface.
■
Be careful not to damage the small parts located on both sides of the motherboard
unit.
Caution – The heat sinks can be damaged by incorrect handling. Do not touch the
heat sinks while replacing or removing motherboard units. If a heat sink is loose or
broken, obtain a replacement motherboard unit. When storing or carrying a
motherboard unit, ensure that the heat sinks have sufficient protection.
