System diagnostics and indicator codes
Table 11. System diagnostics and indicator codes
| Icon | Indicator, button, or connector | Description |
 |
Power-on indicator, power button | The power-on indicator lights when the system powered on. The power button controls the power supply output to the system.
NOTE: On APCI-compliant operating system, turning off the system using power button causes the system to perform a graceful shutdown before power to the system is turned off. |
 |
Health indicator | Indicates the health of the system.
● If the system is powered on and in good health, the indicator lights solid blue. No corrective action is required ●The indicator blinks amber if the system is on or in standby, and if any error exists (For example, a failed fan). See the System Event Log or system messages for the specific issue. For information about the event and error messages generated by the system firmware and agents that monitor system components, go to qrl.dell.com > Look Up > Error Code, type the error code, and then click Look it up.Invalid memory configurations can cause a blank screen or no video output. See the Getting help section. |
 |
System identification button | The identification button on the front and back panels can be used to locate a particular system within a rack. When one of these buttons is pressed, the corresponding system identification button on the back flashes until one of the buttons is pressed again.
Press the system identification button to turn the system ID on or off. If the system stops responding during POST, press and hold the system ID button for more than five seconds to enter BIOS progress mode. To reset iDRAC (if not disabled in F2 iDRAC setup), press and hold the button for more than 15 seconds. |
NIC indicator codes
Each NIC on the back panel has an indicator that provides information about the network activity and link status. The activity LED indicates whether the NIC is connected or not. The link LED indicates the speed of the connected network.

Table 12. NIC indicators
| Convention | Status | Condition |
| A | Link and activity indicators are off. | The NIC is not connected to the network. |
| B | Link indicator is green. | The NIC is connected to a valid network at its |
| maximum port speed (1 Gbps or 10 Gbps). | ||
| C | Link indicator is amber. | The NIC is connected to a valid network at less than its |
| maximum port speed. | ||
| D | Activity indicator is flashing green. | Network data is being sent or received. |

A valid power source is connected to the PSU and the PSU is operational.
When the firmware of the PSU is being updated, the PSU handle flashes green. CAUTION: Do not disconnect the power cable or unplug the PSU when updating firmware. if firmware update is interrupted, the PSUs do not function. When hot-adding a PSU, the PSU handle flashes green five times at 4 Hz rate and turns off. This indicates a PSU mismatch with respect to efficiency, feature set, health status, and supported voltage. CAUTION: If four PSU are installed, the four PSUs must have the same type of label; for example, Extended Power Performance (EPP) label. Mixing PSU from previous generations of PowerEdge servers is not supported, even if the PSU has same power rating. This results in a PSU mismatch condition or failure to turn the system on. CAUTION: When correcting a PSU mismatch, replace only PSU with the blinking indicator. Swapping the PSU to make 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 turn off the system CAUTION: The 120 V AC PSU is not recommended for this system. Operating at 120 V AC results in the 2400W PSU de-rating to only 1400W, which can affect power redundancy policy and possibly system throttling. CAUTION: If four PSUs are used, they must be of the same type and have the same maximum output power. Indicates a problem with the PSU. Power is not connected to the PSU. |
