Setting Up the System 2-39Note: Even if one of the hard disks fails in disk arrayconfiguration (RAID1, RAID5, or RAID0+1), the server cancontinue operation. However, replace the disk as soon aspossible, and perform reconstruction (rebuild) processing.(The failing disk can be replaced in hot swap mode.)! Flashing switching back and forth between green and amber indicatesthat reconstruction (rebuild) processing is being performed for the harddisk. (This flashing does not indicate a failure.) When a failing hard diskis replaced in disk array configuration, the system automatically rebuildsthe data. (Auto-rebuild function) The lamp switches back and forthbetween green and amber during rebuild processing.The lamp goes off when the rebuild processing has terminated. It turnsamber when the rebuild processing fails.Note: If the server is turned off during rebuildprocessing, the processing is stopped. Restart the server,mount the new hard disk in hot swap mode, and thenperform the rebuild processing again. Observe the followingnotes on using the auto-rebuild function:Do not turn the power off. (Once the power is turned off, theauto-build function does not start.)Let 90 seconds or more pass between dismounting a failinghard disk and when mounting a new one.Do not replace a failing hard disk while rebuild processing isbeing performed for another hard diskLAN Connector LampsThere are two lamps for each of the two LAN ports (connectors) on the rearpanel. See Figure 2-37, Q, R, T, and V for the locations of the LAN connectorlamps.LINK/ACT LampsEach LINK/ACT lamp indicates the status of the standard network port of theserver. While power is supplied to the server and HUB and the connection iscorrect, the lamp is on green. (LINK) The lamp turns green and flashes whilethe network port is transmitting/receiving data. (ACT)Speed lampThis lamp indicates whether the network port is operating through a 1000BASE-T, 100BASE-TX or 10BASE-T network interface. If the lamp is lit amber, thenetwork port is operating through 1000BASE-T. If the lamp is lit green, thenetwork port is operating through 100BASE-TX. If the lamp is off, the networkport is operating through 10BASE-T.
