followed can result in data loss, data corruption, or damage to hardware or software.
General safety recommendations
•
Make sure the installation site is flat, vibration-free, and away from electromagnetic
interferences. Make sure ESD and anti-slip measures are in place.
•
Keep the chassis and installation tools away from walk areas.
•
Do not place the device on an unstable case or desk. The device might be severely damaged in
case of a fall.
•
Keep the chassis clean and dust-free.
•
Do not place the device near water or in a damp environment. Prevent water or moisture from
entering the device chassis.
•
Install the device in a standard 19-inch rack.
•
If multiple racks exist in an equipment room, connect these racks for stability purposes and
ease of installation.
•
Make sure the rack is securely seated with the supporting legs closely contacting the floor. All
the weight must be supported by the supporting legs.
•
Remove a maximum of one device from a rack at one time.
•
Use two people to install the device to or pull the device out of a rack to ensure stability. If the
installation position is above the chest, use one more people to help adjust the device
orientation.
•
Make sure the rack is securely seated on the floor before installing or removing the device.
•
To ensure good ventilation, install blanks over unused rack space and the empty power supply
slot.
•
To ensure good ventilation, make sure the air inlet and outlet vents of the device are not blocked.
If you are to install multiple devices in a rack, make sure there is a minimum of 2 mm (0.08 in)
clearance between every two devices.
•
Remove all cables from the device before moving it.
•
Make sure the output voltage of the power supplies is as required.
•
Use a screwdriver to fasten screws.
•
After you move the device from a location below 0°C (32°F) to the equipment room, follow these
guidelines to prevent condensation:
Wait a minimum of 30 minutes before unpacking the device.
Wait a minimum of 2 hours before powering on the device.
Electricity safety
WARNING!
If you put the device in standby mode (system LED in amber) with the
button on the front panel,
the power supplies continue to supply power to some circuits in the device. To remove all power for
servicing safety, you must first press the button until the system enters standby mode, and then
remove all power cords from the device.
CAUTION:
As a best practice to avoid device impairment caused by voltage fluctuation and power failure, use a
UPS as the external power source.
