Installing SAN Director 2/128 FRUs Replacing a WWN Card Use these steps to replace a WWN card. The following items are needed to replace the WWN card: ■ ESD (electrostatic discharge) grounding strap ■ If a serial console session is used, a serial cable and a workstation computer with a terminal emulator application (such as HyperTerminal for Windows systems or TIP for Solaris systems.) Caution: Do not power cycle or reboot the SAN Director 2/128 or replace the CP cards or port cards until the WWN card is verified as functional or a replacement WWN card is installed. If any of these events happen while the WWN card is failed or uninstalled, the configuration information is lost, and it will be necessary to reconfigure the SAN Director 2/128 after installing the new WWN card. Disassembling any part of the WWN card voids the part warranty and regulatory certifications. The WWN card contains no user-serviceable parts. Figure 28 shows the nonport side of the SAN Director 2/128, which contains the WWN bezel and card. Replacing the WWN Card This procedure requires a telnet session or a serial console session with the SAN Director 2/128. If a serial console session is used, a serial cable and a workstation computer with a terminal emulator application (such as HyperTerminal for Windows systems or TIP for Solaris® systems) are required.
