Safety and Regulatory Information
Observe extension cable and power strip ratings. Ensure that the total ampere rating of all
•
products plugged into the extension cable or power strip does not exceed 80% of the ampere
ratings limit for the extension cable or power strip.
To protect the equipment from sudden, transient increase or decrease in electrical power, use
•
a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
Do not modify power cables or plugs. Consult a licensed electrician or your power company
•
for site modifications. Always follow your local/national wiring rules.
To avoid possible damage to the system board, wait 5 seconds after turning off the system
•
before removing a component from the system board or disconnecting a peripheral device.
When connecting or disconnecting power to the hot-pluggable power supply units, observe the
•
following guidelines:
Unplug the power cable before removing the power supply.
•
Install the power supply to the system before connecting the power cable to 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.
When disconnecting a cable, pull on its connector or on its strain-relief loop, and not on the
•
cable itself.
Installation Assembly Safety Instructions
1.4.2
The power supply in this product contains no user-serviceable parts. Refer servicing only to
•
qualified personnel.
Do not attempt to modify or use the supplied AC power cord if it is not the exact type required.
•
A product with more than one power supply will have a separate AC power cord for each
supply.
To remove the AC power from the system, you must unplug each AC power cord from the wall
•
outlet or power supply. The power cord(s) is considered the disconnect device to the main
(AC) power. The socket outlet that the system plugs into shall be installed near the equipment
and shall be easily accessible.
A microprocessor and heat sink may be hot if the system has been running. Also, there may
•
be sharp pins and edges on some board and chassis parts. Contact should be made with
care. Consider wearing protective gloves.
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or
•
equivalent type recommended by the equipment manufacturer. Dispose of used batteries
according to manufacturer’s instructions.
The system is safety certified as rack-mounted equipment for use in a server room or
•
computer room, using the customer rack kit. The rail racks are designed to carry only the
weight of the system. Do not place additional load onto any rail-mounted equipment. System
rack kits are intended to be installed in a rack by trained service technicians.
Site Selection
1.4.3
The system is designed to operate in a typical office environment. Choose a site that is:
Clean and free of airborne particles (other than normal room dust).
•
Well ventilated and away from sources of heat including direct sunlight and radiators.
•
Away from sources of vibration or physical shock.
•
Isolated from strong electromagnetic fields produced by electrical devices.
•
In regions that are susceptible to electrical storms, we recommend you plug your system
•
into a surge suppressor and disconnect telecommunication lines to your modem during an
electrical storm.
