Fujitsu SPARC M12-1 Installation Manual page 18

Contact a service engineer for details of SPARC M12-1 inspection and PCI
■
expansion unit inspection.
Safety precautions when working with electricity
Confirm that the voltage and frequency of your input power match the electrical
■
rating described on the system name plate label affixed on the server.
Make sure to wear a wrist strap when handling the internal storage (HDD/SSD),
■
motherboard unit, memory, or other printed circuit boards.
Make sure to use grounded power outlets.
■
Do not make mechanical or electrical modifications to the chassis. We do not take
■
responsibility for regulatory compliance of a modified chassis.
Do not disconnect a power cord from the chassis while it is still powered on.
■
Safety precautions regarding racks
The rack must be secured to the floor, ceiling, or nearest frame.
■
The quakeresistant options kit may be supplied with the racks. The use of the
■
quakeresistant options kit prevents the rack from toppling over when the chassis
is pulled out from the slide rails for installation or maintenance.
In the following cases, a safety evaluation must be performed by a service
■
engineer before installation or maintenance.
- If the quakeresistant options kit is not supplied and the rack is not secured to the
floor with bolts, a service engineer confirms the safety of the rack, such as by
verifying that it does not topple over when the chassis is pulled out from the
slide rails.
- If the rack is mounted on a raised floor, a service engineer confirms that the floor
can withstand the load when the chassis is pulled out from the slide rails. Secure
the rack to the concrete floor beneath the raised floor by using the original
mounting kit that serves this purpose.
If multiple SPARC M12-1 units and PCI expansion units are mounted in the rack,
■
perform maintenance on one unit at a time.
Safety precautions regarding installation work
With this chassis installed in a closed or multi-unit rack assembly, the ambient
■
temperature inside the rack operating environment may be greater than the
ambient room temperature. Therefore, consideration must be given to installing
the chassis in an environment compatible with the manufacturer's maximum rated
ambient temperature.
- Consideration of air-conditioning adjustments, such as air circulation, is needed
to prevent the ambient temperature inside the rack from exceeding the
maximum ambient operating temperature of this chassis.
- Maximum ambient operating temperature of this chassis: 35°C
The installation of the chassis in a rack should allow sufficient airflow for the
■
chassis to operate safely.
- This chassis has ventilation slits at the front and rear of the chassis.
