Hard-Drive Indicator CodesEach hard-drive carrier has two indicators: a busy indicator and a status indicator (see Figure 3-5). The indicators provide information on the status of therespective hard drive. Table 3-6 lists the drive indicator codes.Figure 3-5. Hard-Drive IndicatorsTable 3-6 lists the drive indicator codes. Different codes display as drive events occur in the system. For example, in the event of a hard-drive failure, the "drivefail" code appears. After the drive is selected for removal, the "preparing for removal" code appears. After the replacement drive is installed, the "preparing foroperation, drive online" code appears.Table 3-6. Hard-Drive Indicator CodesNIC Indicator CodesEach NIC on the back panel has an indicator that provides information on network activity and link status (see Figure 3-6). Table 3-7 lists the NIC indicatorcodes on the back panel.The front panel has a link indicator for each NIC (see Figure 3-2). Each indicator signifies whether the corresponding NIC is connected to a valid link partner onthe network.Figure 3-6. NIC IndicatorsTable 3-7. NIC Indicator CodesERA/O Ethernet Connector Indicator CodesThe optional embedded remote access (ERA/O) Ethernet connector indicators on the back panel provide information on network activity and link status for theERA/O Ethernet connector (see Figure 3-7). Table 3-8 lists the ERA/O Ethernet connector indicator codes.Figure 3-7. ERA/O Ethernet ConnectorDrive Status Indicator Indicator CodeDrive bay empty, ready for insertion or removal OffDrive being prepared for operation, drive online Steady greenDrive being identified Blinks green four times per secondDrive being prepared for removal Blinks green twice per second at equal intervalsDrive rebuilding Blinks green twice per second at unequal intervalsDrive failed Blinks amber four times per secondPredicted failure for the drive Blinks green, then amber, and then off, repeating this sequence every two secondsNOTE: The drive-busy indicator signifies whether the hard drive is active on the SCSI bus. This indicator is controlled by the hard drive.Indicator Indicator CodeLink and activity indicators are off The NIC is not connected to the network.Link indicator is green The NIC is connected to a valid link partner on the network.Activity indicator is amber blinking Network data is being sent or received.
