Operating the SAN Director 2/128 Table 14: Troubleshooting the SAN Director 2/128 (Continued) Issue Modems are not detected by switch. Ethernet link speed is different than expected or a link cannot be established. Configuration data is inaccurate or cannot be accessed. Initial setup results in IP address/Domain ID conflict. Possible Cause Modems were connected after the SAN Director 2/128 was powered on. Modems are connected to the wrong ports on the CP cards. Modems are not correctly configured. Pins on the modem cable or modem port might be damaged. There might be a conflict with the Ethernet link speed negotiation set up by the network. Chassis was powered off/on while the WWN card was uninstalled or failed. The switch was rebooted while the WWN card was uninstalled or failed. The switch was connected to the fabric before being configured. Recommended Action Reboot the CP card(s) to which the modem(s) are connected. Ensure that the modem cables are connected to the ports labeled "RS232" (the serial ports intended for terminal use are labeled 10101). Verify that the modems are configured as specified in "Setting Up and Installing Modems" on page 153. Remove the cable and inspect the pins on the cable and in the port. Do not reinstall if the pins on either component have any visible damage, as this could damage the pins on the other component. Replace components as required. Specify the Ethernet link speed by entering the ifmodeset command. Install an operational WWN card and power the system off/on again. Refer to "Initial Configuration Parameters" on page 67 and the HP StorageWorks Fabric OS 4.2.s Procedures User Guide for configuration information. 102 SAN Director 2/128 Installation Guide
