NBX IP Telephony Platforms 27 Table 6 V3001R Connectors and LEDs (continued) 9 Ethernet 10/100 switched Ethernet connection redundant uplink ports. Use either Ethernet port to connect to the LAN. If the other port is connected, it becomes active only when the active port experiences a link failure. The ports stay in that state even after the failed port returns to a positive link state. Both ports show a positive link status even though only one port at a time is active. Typically, you would connect each port to a different switch and subnet. LNK/SPEED: ■ Yellow - 10Mbit link ■ Green - 100Mbit link ■ Off - No link ACT: ■ Flashing Green - Activity on port ■ Off - No activity Table 7 V3001R System Status LEDs - S1 and S2 Explanation S1 S2 Attempting to boot from disk 1 (zero) Off Flashing Attempting to boot from disk 2 Flashing Off Flash codes for disk problems: Unison flashing ■ 2 flashes: No valid disk (system is halted). ■ 3 flashes: Two valid disks, but they are not paired (system is halted). ■ 4 flashes: Configuration problem (system is halted). ■ 5 flashes: Two disks present, but no mirroring license installed. System is running but the system is not using the second disk. Using disk 1 only Off On Using disk 2 only On Off Synchronizing - disk 1 is valid, disk 2 is becoming a fully mirrored disk. Flash rate indicates progress. Flashing On If S1 and S2 stop normal flashing and intermittently flash twice, the mirroring process has failed. Synchronizing - disk 2 is valid, disk 1 is becoming a fully On Flashing mirrored disk. Flash rate indicates progress. If S1 and S2 stop normal flashing and intermittently flash twice, the mirroring process has failed.
