Table 111. AC and DC PSU status indicator codes (continued)
Power indicator codes
NIC indicator codes
Each NIC on the back of the system has indicators that provide information about the activity and link status. The activity LED
indicator indicates if data is flowing through the NIC, and the link LED indicator indicates the speed of the connected network.

System diagnostics and indicator codes
Condition
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:
If two PSUs are used, they must be of
the same type and have the same maximum output
power.
CAUTION:
When correcting a PSU mismatch, replace
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:
When two identical PSUs receive different
input voltages, they can output different wattage,
and trigger a mismatch.
For example a 1100W PSU connected to a High-Line AC
(HLAC) 200Vac-240Vac input, it will output 1100W. But if a
second 1100W PSU in the same system is connected to a Low
Line 100-120Vac input, it will only output 1050W, triggering a
mismatch.
Condition
Indicates that the NIC is not connected to the network.
Indicates that the NIC is connected to a valid network at its maximum
port speed, and data is being sent or received.
Indicates that the NIC is connected to a valid network at less than its
maximum port speed, and data is being sent or received.
Indicates that the NIC is connected to a valid network at its maximum
port speed, and data is not being sent or received.
Indicates that the NIC is connected to a valid network at less than its
maximum port speed, and data is not being sent or received.
