2. Hardware Installation/Uninstallation For hardware installation/uninstallation, refer to the User’s Guide of the server. - When the system is up, please turn the power off after shutdown process on the OS. and then unplug the AC power cord - For rack-type server, before open the top cover, need to disconnect the cable from this IMPORTANT: product.
Depending on the type of system, installation of this product requires either a standard bracket or a low-profile bracket. NEC provides both of these brackets with the product. By default Full Height bracket is attached. Please replace the bracket according to the following steps as necessary.
3. Optical module Installation / Uninstallation Avoid installation in extreme temperature conditions. The optical module may become hot. If you replace during operation, please remove the cable and change the temperature of the module before replacing it. Notes on the N8104-212/221 firmware (NVM3.20) included in StarterPackS8.10- 010.05.
