Table 39. NIC indicator codes (continued) NIC indicator codes Link indicator is green, and activity indicator is off. Link indicator is amber, and activity indicator is off. Link indicator is blinking green, and activity is off. Condition 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 mot being sent or received. Indicates that the NIC identify is enabled through the NIC configuration utility. Power supply unit indicator codes AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator. The indicator shows if power is present or if a power fault has occurred. Figure 16. AC PSU status indicator 1. AC PSU handle 2. Socket 3. Release latch Table 40. AC PSU status indicator codes Power indicator codes Green Blinking amber Not powered on Blinking green Blinking green and powers off Condition Indicates that a valid power source is connected to the PSU and the PSU is operational. Indicates an issue with the PSU. Indicates that the power is not connected to the PSU. Indicates that the firmware of the PSU is being updated. CAUTION: Do not disconnect the power cord or unplug the PSU when updating firmware. If firmware update is interrupted, the PSUs do not function. 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. CAUTION: If two PSUs are installed, both the PSUs must have the same type of label; for example, Extended Power Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge 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. System diagnostics and indicator codes 31
