2-14 Setting Up the System
After the power cords are plugged in confirm that the power status lamp on the
power units flashes. If the lamp is off, a failure occurred in the power unit, see
Table 1-1 System Status LED Indicators in Chapter 1 of this User's Guide.
When connecting the power cord to a power control unit, such as an UPS
confirm that the power control unit is powered off. Connecting the power cord
while power is supplied to the power control unit may cause a failure.
! WARNING
Your system shipped with a power cord for each power
supply. Do not attempt to modify or use the supplied AC
power cord if it is not the exact type required.
!
CAUTION
The power plug from each of the power supplies must be
plugged into the same common ground power outlets.
