Safety Precautions
Observe the following precautions when handling the equipment:
Server power ON/OFF:
The push-button on/off power switch on the front panel of
the server does not turn off the power. To remove power from the server, you must
unplug the power cord from either the power supply or wall outlet.
Power supply:
Hazardous voltage, current, and energy levels are present inside the
power supply enclosure.
Devices and cables:
Hazardous electrical conditions may be present on power,
telephone, and communication cables. Turn off the server and disconnect
telecommunications systems, networks, modems, and the power cord attached to
the server before opening it. Otherwise, personal injury or equipment damage can
result.
Maintenance:
There are no user-serviceable parts inside the Vision AQR1U Server.
Only technically qualified personnel should perform service and maintenance tasks.
Avoid injury:
Lifting the server and attaching it to the rack is a two-person job. If
needed, use an appropriate lifting device.
Electrostatic Discharge Protection (EDP):
Use proper ESD protection.
Electrostatic Discharge (ESD) protective straps, shoes, or mats must be used when
working with electronic components. Electrostatic discharge from your body can
damage integrated circuits during installation.
DC systems:
For DC systems, each unit should be on it's own branch circuit.
Uneven loading:
Use caution when mounting the equipment in the rack so that a
hazardous condition is not achieved due to uneven mechanical loading.
