Locating the Express Service Code and Service Tag

The unique Express Service Code and Service Tag are used to identify the system.
The information tag is located on the rear of the system that includes system information such as iDRAC MAC address, Express
Service Tag label.
Condition
CAUTION:
the PSU with the blinking indicator. Swapping the
PSU to make a matched pair can result in an error
condition and an unexpected system shutdown. To
change from a high output configuration to a low
output configuration or vice versa, you must power
off the system.
CAUTION:
input voltages with the exception of Titanium PSUs,
which support only 240 V. When two identical PSUs
receive different input voltages, they can output
different wattages, and trigger a mismatch.
Condition
Indicates that a valid power source is connected to the PSU,
and the PSU is operational.
Indicates an issue with the PSU.
Indicates that the power is not connected to the PSU.
When hot-plugging a PSU, it blinks green five times at a rate
of 4 Hz and powers off. This indicates a PSU mismatch due to
efficiency, feature set, health status, or supported voltage.
CAUTION:
must have the same type of label; for example,
Extended Power Performance (EPP) label. Mixing
PSUs from previous generations of PowerEdge
servers is not supported, even if the PSUs have the
same power rating. This results in a PSU mismatch
condition, or failure to power on the system.
CAUTION:
the same type and have the same maximum output
power.
CAUTION:
the PSU with the blinking indicator. Swapping the
PSU to make a matched pair can result in an error
condition and an unexpected system shutdown. To
change from a High Output configuration to a Low
Output configuration or conversely, you must power
off the system.
CAUTION:
supported.
