Corrective Action |
|
Drive indicator |
The indicator turns solid amber if there is a drive error |
|
|
Temperature indicator |
The indicator turns solid amber if the system experiences a thermal error (for example, the ambient temperature is out of range or there is a fan failure) |
Ensure that none of the following conditions exist:
|
|
Electrical indicator |
The indicator turns solid amber if the system experiences an electrical error (for example, voltage out of range, or a failed power supply unit (PSU) or voltage regulator) |
Check the System Event Log or system messages for the specific issue. If it is due to a problem with the PSU, check the LED on the PSU. Reseat the PSU. |
|
Memory indicator |
The indicator turns solid amber if a memory error occurs |
Check the System Event Log or system messages for the location of the failed memory. Reseat the memory module. |
|
PCIe indicator |
The indicator turns solid amber if a PCIe card experiences an error |
Restart the system. Update any required drivers for the PCIe card. Reinstall the card. |
System Health and System ID Indicator Codes
The system health and system ID indicator is located on the left control panel of the system.
|
System Health and System ID Indicator Code |
Condition |
|
Solid blue |
Indicates that the system is powered on and healthy, and that system ID mode is not active. Press the system health and system ID button ( 
) to switch to system ID mode. |
|
Blinking blue |
Indicates that the system ID mode is active. Press the system health and system ID button to switch to system health mode. |
|
Solid amber |
Indicates that the system is in fail-safe mode. |
|
Blinking amber |
Indicates that the system is experiencing a fault. Check the System Event Log for specific error messages. |
The LEDs on the drive carrier indicate the state of each drive. Each drive carrier has two LEDs: an activity LED (green) and a status LED (bicolor, green/amber). The activity LED blinks whenever the drive is accessed.

RJ-45 Remote Management Port
The remote management port is designed for secure local and remote server management and helps IT administrators deploy, update, and monitor the NVIDIA® MetroX-3 XC Appliance.
RJ-45 Management Ports eth0-eth1
These four RJ-45 ports are found on the rear side of the appliance. The eth0-eth1 and remote management interfaces are pre-configured as DHCP and the initial host name is MetroX3xc-1 (the MAC address appears on the pull-tab label), so their IP addresses can be obtained from the DHCP server. If no DHCP server is available, you have to use a serial cable to connect and configure eth0 and remote-management IP addresses with a static IP address.
Configuring the appliance via the serial port is required only in the case where out-of-the-box DHCP configuration for eth0 cannot be used. (There is no DHCP server in the management network). The user is then required to use the serial port to configure a static IP on eth0.
NIC#1 Ethernet connector gets connected to Ethernet switches. This switch must be configured to 100M/1G auto-negotiation.
ConnectX-7 OSFP Ports
These 2 OSFP ports are found on the rear side of the appliance. They should be connected to an IB switch in the fabric. It is recommended to connect to two different switches for redundancy. The appliance can be connected only to a single IB fabric.
RJ-45 Ethernet Connector for Remote Management
The appliance has several Ethernet management interfaces. The primary management interface is eth0. An additional interface exists, for connecting to a remote management controller (it usually connects to the same management network as eth0).
To use out-of-the-box DHCP settings, the default hostname for the appliance (over eth0) is "MetroX3xc-1". The MAC address for eth0 is available on the pull-tab and can be configured in the DHCP server.
To use the remote management controller with DHCP, the free-range IP allocation must be enabled on the DHCP server. A static IP address for remote management interface can be configured via the CLI (chassis remote-management ip command).
Configuration via a serial port is only required if you want to use a static IP address and not the out-of-the-box DHCP setting for eth0. Otherwise, an IP is assigned by the DHCP server, and you can log into the CLI over LAN.
NIC#1 Ethernet connector gets connected to Ethernet switches. This switch must be configured to 100M/1G auto-negotiation.
USB Interface
There are two USB connectors. These connectors can be used to install software and/or firmware upgrades using a memory device that has a USB connector. This connector is USB 2.0 compliant. Various upload/download operations are also supported through the USB using the CLI.

Each power supply (PS) unit has a one built-in fan and a single two-color LED on the right side of the PS unit that indicates the internal status of the unit.
The following table presents the AC PSU status indicator codes:
|
Power Indicator Codes |
Condition |
|
Green |
Indicates that a valid power source is connected to the PSU and the PSU is operational |
|
Blinking amber |
Indicates an issue with the PSU |
|
Not powered on |
Indicates that the power is not connected to the PSU |
|
Blinking green |
Indicates that the firmware of the PSU is being updated Important
Do not disconnect the power cord or unplug the PSU when updating firmware. If firmware update is interrupted, the PSUs will not function.
|
|
Blinking green and powers off |
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. Important
If two PSUs are used, they must be of the same type and have the same maximum output power.
Important
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.
Important
When two identical PSUs receive different input voltages, they can output different wattage, and trigger a mismatch.

The following table presents the D C PSU status indicator codes:

|
Blinking green |
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. |
NIC Activity LED Indicators
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.
