• The following are precautions for the left, right, top, and bottom sides of the equipment:
• Do not attach heating devices.
• For ease of maintenance work, verify that the equipment can be moved easily. If the equipment is secured,
ensure that the equipment can be removed easily.
• It is reported that zinc whiskers can cause a problem with the equipment. Do not use electrogalvanized materials
near the equipment or the place where the equipment is installed.
(A quote from Technical Report of JEITA
Systems")
Location of whiskers: Whiskers are created by electrogalvanized equipment such as floor panels, stringers, posts,
Phenomenon: Hair-like zinc crystals (conductive whiskers) float into the air from the floor for some reason, go
inside the device, and short-circuit a PCB or its pins. The root cause is difficult and time-consuming
to determine, because the symptoms differ depending on the location of the short circuit, and often,
the problem is mistakenly identified as a temporary issue.

Required actions
• If you mount the equipment in a chassis or on a desk, take into consideration the temperature increase around the
equipment.
• The system clock and similar operations inside the equipment always operate by using a backup battery, even
when the power is off. Therefore, if you store the equipment at a temperature outside the operating temperature
range, you might need to reconfigure the clock settings and other system BIOS settings when you start using the
equipment again. When reconfiguring system BIOS settings, follow the instructions in 5.6 BIOS Setup.

Precautions
• Before moving the equipment, unplug the power cord and wait at least one minute.
• To prevent moisture condensation when moving the equipment from outside a building to the inside, wait at least
four hours before using the equipment.
• The equipment is made by using precision electronics components. Do not subject the equipment to any vibrations
or shocks.
• Do not sit on the equipment or place anything on the equipment.
• During normal operation, do not turn off the display. Set the display to standby mode instead.
• When you turn on the equipment, during normal operation, do not touch the keyboard or mouse until the logon
