Safety Notices
!
! Caution: To reduce the risk of electric shock which could cause personal injury,
follow all safety notices. The symbols shown are used in your documentation and on
your equipment to indicate safety hazards.
! Warning: Detachable power supply cords are intended to serve as the disconnect
device.
! Warning: This equipment has a 3-wire, grounded power cord. To prevent electrical
hazards, do not remove or defeat the ground prong on the power cord. Replace the
power cord if it gets damaged. Contact your dealer for an exact replacement.
! Warning: The DC push-button on/off switch on the front panel of your server does
not turn off the system AC power. Also, +5vdc is present on the system board
whenever the AC power cord is connected between the system and an AC outlet.
Before doing the procedures in this manual, make sure that your system is powered
off and unplug the AC power cord from the back of the chassis. Failure to disconnect
power before opening your system can result in personal injury and equipment
damage.
All Servers and Peripherals installed inside a rack:
In the U.S.A. and Canada, the power cord must be a UL-listed detachable power cord
(in Canada, CSA-certified), type ST or SJT, 16 AWG, 3-conductor, provided with a
molded-on NEMA type 5-15 P plug cap at one end and a molded-on cord connector
body at the other end. The cord length must not exceed 6.56 feet (2.0 meters).
Outside the U.S.A. and Canada, the plug must be rated for 250 VAC, 10 amp minimum,
and must display an international agency approval marking. The cord must be suitable
for use in the end-user country. Consult your dealer or the local electrical authorities if
you are unsure of the type of power cord to use in your country. The voltage change
occurs via a switch in the power supply.
! Warning: Under no circumstances should the user attempt to disassemble any
power supply. A power supply has no user-replaceable parts. Inside the power
supply are hazardous voltages that can cause serious personal injury. A defective
power supply must be returned to your dealer.
Safety Notices for Users Outside of the U.S.A. and Canada
