The LEDs provide the status information of the server and the activity on its ports.
Power supply status LED
To indicate power supply status, there is a single bi-color LED. The LED operation is defined as:
Power Supply Condition | LED State |
|---|---|
Output ON and OK | Green |
No AC power to all power supplies | OFF |
AC presents or only 12VSB on (PS off) or PS in Cold redundant state | 1 Hz Blink Green |
AC cord unplugged or AC power lost; with a second power supply in parallel still with AC input power. | Amber |
Power supply warning events where the power supply continues to operate; high temp, high power, high current, slow fan. | 1 Hz Blink Amber |
Power supply critical event causing a shutdown; failure, OCP, OVP, Fan Fail | Amber |
Power supply FW updating | 2 Hz Blink Green |
External RJ45 NIC Port LED
Each ethernet port drives two LEDs on each network interface connector (NIC). The LED on the connector indicates link speed.
LED | Color | LED State | NIC State |
|---|---|---|---|
Left | Green | Off | LAN link not established |
On | LAN link is established | ||
Blink | Transmit or receive activity | ||
Right | - | Off | Lowest supported data rate |
Amber | On | Mid-range supported data rate | |
Green | On | Highest supported data rate |
System Status LED
Indicate the current health of the server system.
Color | State | Criticality | Description |
|---|---|---|---|
Off | System is not operating | Not ready |
|
Green | Solid on | OK | The system is running (in S0 State) and the status is Healthy. |
Green | 1-Hz blink | Degraded - system is functional, or system is operating in a redundant state but with an impending failure warning | System degraded: Redundancy loss, Fan warning, Non-critical threshold crossed, Power supply predictive failure, and Battery failure. |
Amber | 1-Hz blink | Non-critical - system is operating in a degraded state with an impending failure warning, although still functioning | Non-fatal alarm – system is likely to fail. |
Amber | Solid on | Critical, non-recoverable – System is halted | Fatal alarm – system has failed or shutdown. |
Drive Activity and Status LED
Each drive carrier includes separate LED indicators for drive Activity and drive Status.
Amber | Off | No access and no fault |
Solid On | Hard Drive Fault has occurred | |
Blink | RAID rebuild in progress (1 Hz), Identify (2 Hz) |
Condition | Drive Type | Behavior | |
|---|---|---|---|
Green | Turn on with no drive activity | SAS | LED stays on |
SATA | LED stays off | ||
Turn on with drive activity | SAS | LED blinks off when processing a command | |
SATA | LED blinks on when processing a command | ||
Turn on and drive spun down | SAS | LED stays off | |
SATA | LED stays off | ||
Turn on and drive spinning up | SAS | LED blinks | |
SATA | LED stays off |
Power or Sleep button
Toggles the system turn on and off. This button also functions as a sleep button if enabled by an advanced configuration and power interface (ACPI) compliant operating system.
State | Power Mode | LED | Description |
|---|---|---|---|
Turn off | Non-ACPI | Off | System power is off, and the BIOS has not initialized the chipset. |
Turn on | Non-ACPI | On | System power is on. |
S5 | ACPI | Off | Mechanical is off, and the operating system has not saved any context to the hard disk. |
S0 | ACPI | Steady On | System and the operating system are up and running. |
BMC Boot or Reset Status LED indicators
A baseboard management controller (BMC) boot occurs when AC power is first applied to the system. A BMC reset occurs after a BMC FW update, on receiving a BMC cold command, and on a BMC watchdog initiated reset.
BMC Boot or Reset State | ID LED | Status LED | Description |
|---|---|---|---|
BMC or Video memory test failed | Solid Blue | Solid Amber | Non-Recoverable condition. Contact Trellix support for information about replacing the motherboard. |
Both Universal Bootloader (u-Boot) images bad | Solid Blue | Solid Amber | Non-Recoverable condition. Contact Trellix support for information about replacing the motherboard. |
BMC in u-Boot | Blink Blue 3 Hz | Blink Green 1 Hz | Indicates degraded state, blinking blue indicates u-Boot is running but has not transferred control to BMC Linux. Server is in this state for 6–8 seconds. |
BMC Booting Linux | Solid Blue | Solid Green | Indicates that the control is passed from u-Boot to BMC Linux itself. Server is in this state for 10–20 seconds. |
End of BMC boot or reset process. Normal system operation | Off | Solid Green | Indicates BMC Linux is booted and manageability function is up and running. |
