Electrical indicator
Condition Corrective Action
The indicator blinks
amber if the system
experiences an
electrical error (for
example, voltage out
of range, or a failed
power supply or
voltage regulator).
See the System Event Log or system messages for the specific issue.
If it is due to a problem with the power supply, check the LED on the
power supply. Re-seat the power supply by removing and reinstalling
it. If the problem persists, see Getting Help.
13

Temperature indicator
Condition Corrective Action
The indicator blinks
amber if the system
experiences a
thermal error (for
example, a
temperature out of
range or fan failure).
Ensure that none of the following conditions exist:
• A cooling fan is removed or has failed.
• System cover, cooling shroud, EMI filler panel, memory-
module blank, or back-filler bracket is removed.
• Ambient temperature is too high.
• External airflow is obstructed.
See Getting Help.
Memory indicator
Condition Corrective Action

NIC Indicator Codes
Figure 7. NIC Indicator
1. link indicator
2. activity indicator
Indicator Indicator Code
Link and activity
indicators are off
The NIC is not connected to the network.
Link indicator is
green
The NIC is connected to a valid network at its maximum port speed (1 Gbps or 10 Gbps).
Link indicator is
amber
The NIC is connected to a valid network at less than its maximum port speed.
Activity indicator is
blinking green
Network data is being sent or received.
Power Indicator Codes
Each AC power supply has an illuminated translucent handle and each DC power supply (when available) has an LED
that serves as an indicator to show whether power is present or whether a power fault has occurred.
Figure 8. AC Power Supply Status Indicator

Figure 9. DC Power Supply Status Indicator
1. DC power supply status indicator
Power Indicator
Pattern
Condition
Not lit Power is not connected.
Green The handle/LED indicator lights green indicating that a valid power source is connected to the
power supply and that the power supply is operational.
Flashing amber Indicates a problem with the power supply.
CAUTION: When correcting a power supply mismatch, replace only the power supply with
the flashing indicator. Swapping the opposite power supply to make a matched pair can
result in an error condition and unexpected system shutdown. To change from a High
Output configuration to a Low Output configuration or vice versa, you must power down
the system.
CAUTION: AC power supplies support both 220 V and 110 V input voltages with the
exception of Titanium power supplies, which support only 220 V. When two identical
power supplies receive different input voltages, they can output different wattages, and
trigger a mismatch.
CAUTION: If two power supplies are used, they must be of the same type and have the
same maximum output power.
CAUTION: Combining AC and DC power supplies is not supported and triggers a mismatch.
Flashing green When hot-adding a power supply, this indicates that the power supply is mismatched with the
other power supply (in terms of efficiency, feature set, health status, and supported voltage).
Replace the power supply that has the flashing indicator with a power supply that matches the
capacity of the other installed power supply.
