Power-Supply Indicator Codes
Each hot-pluggable power supply has three indicators that can provide information on power status, fault, and the presence of AC power (see Figure2-5).
Table2-3 lists the power-supply indicator codes.
Figure 2-5. Power-Supply Indicators
NIC Indicator Codes
Each NIC has an indicator that provides information on network activity and link status (see Figure2-6). Table2-4 lists the NIC indicator codes.
Figure 2-6. NIC Indicators
Blinks green twice per second at equal intervals
Drive being prepared for removal
Blinks green twice per second at unequal intervals
Blinks amber four times per second
Blinks green, then amber, and then off, repeating this sequence every two seconds
Predicted failure for the drive
NOTE: The drive busy indicator identifies whether the hard drive is active on the SCSI bus. This indicator is controlled by the hard drive.
Table 2-3. Power-Supply Indicator Codes
Green indicates that the power supply is operational.
Red indicates a problem with the power supply (fan failure, voltage error, etc.).
Green indicates that AC power is present at the power supply and that the system is connected to an AC source.
Table 2-4. NIC Indicator Codes
The NIC is not connected to the network.
The NIC is connected to a valid link partner.
Network data is being sent or received.
