Important Safety Instructions
• When connecting or disconnecting power to hot-pluggable power supplies, observe the following precautions:
> Install the power supply before connecting the power cable to the power supply
> Unplug the power cable before removing the power supply
> If the system has multiple sources of power, disconnect power from the system by unplugging all power cables from the
power supplies
> Never push objects of any kind into or through cabinet slots. They may touch dangerous voltage points or short out
parts, resulting in a risk of fire or electrical shock
> Do not attempt to service the device yourself. Refer all servicing to qualified service personnel
• If the following conditions occur, unplug the device from the wall outlet and bring it to qualified service personnel for repair:
> The power cord or plug has become damaged or frayed
> Liquid has been spilled into the device
> The device has been exposed to rain or water
> The device has been dropped or the cabinet has been damaged
> The device exhibits a distinct change in performance, indicating a need for service
> The device does not operate normally when the operating instructions are followed
• Adjust only those controls that are covered in the operating instructions. Improper adjustment of other controls may result in
damage that will require extensive repair work by a qualified technician.
Rack Mounting Safety Instructions
• Before working on the rack, make sure that the stabilizers are secured on the rack, extended to the floor, and that the full
weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stabilizers for joined multiple
racks before working on the racks.
• Always load the rack from the bottom up, and load the heaviest item in the rack first.
• Make sure that the rack is level and stable before extending a device from the rack.
• Use caution when pressing the device rail release latches and sliding a device into or out of a rack; the slide rails can pinch
your fingers.
• After a device is inserted into the rack, carefully extend the rail into a locking position, and then slide the device into the rack.
• Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80
percent of the branch circuit rating.
• Make sure that all equipment used on the rack, including power strips and other electrical connectors, is properly grounded.
• Ensure that proper airflow is provided for devices in the rack.
• Ensure that the operating ambient temperature of the rack environment does not exceed the maximum ambient
temperature specified for the equipment by the manufacturer.
• Do not step on or stand on any device when servicing other devices in a rack.
