frequency indicated on the electrical rating label affixed to the chassis.
Make sure to wear a wrist strap when handling the hard disk drive, motherboard
■
unit/CPU memory unit, 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 the power is on.

Safety precautions regarding racks
Racks must be fixed 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 fixed with
bolts to the floor, 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. Fix the
rack to the concrete floor beneath the raised floor by using the original mounting
kit that serves this purpose.
If multiple chassis are mounted in the rack, perform maintenance on one chassis 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 with 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 for sufficient air flow for the
■
chassis to operate safely.
- This chassis has ventilation slits at the front and rear of the chassis.
- To prevent overheating, do not cover or close these ventilation slits.
The mounting of the chassis in the rack should not create any hazardous condition
■
due to uneven mechanical loading. To keep the entire rack stable, fix the rack to
the wall or floor by suitable means.
- Be careful not to injure yourself or others when installing the chassis in the rack.
