Further Problem Description

This defect serves as documentation for Migrating the Nexus 9504 hardware to 400-Gigabit -GX Line Cards. The following section should be added at the end of the "Replacing or Installing Modules, Fan Trays, and Power Supplies" chapter of the "Cisco Nexus 9504 NX-OS Mode Switch Hardware Installation Guide" document. ### Migrating the switch to 400-Gigabit -GX Line Cards You can migrate the switch to using 400-Gigabit -GX line cards, such as the N9K-X9716D-GX line card, by replacing the older 40-Gigabit or 100-Gigabit line cards and replacing the older 40-Gigabit or 100-Gigabit fabric modules with N9K-C9504-FM-G fabric modules. #### **Before you begin** Ensure that the switch is running NX-OS software for release 10.1(2) or later. **Note** When upgrading line cards and their fabric modules, upgrade the Cisco NX-OS software before inserting the line cards and fabric modules. Failure to do so can cause a diagnostic failure on the line card. Classic Line Cards, such as -PQ/-PX/-TX/-TX2, will not boot in NXOS version 10.1(x) and later. This is expected behavior. Please see the release notes for details. #### **Procedure** **Step 1** Save the current switch configuration to the bootflash by using the copy running-config command. ``` switch# copy running-config bootflash:backup-config Copy complete, now saving to disk (please wait)... ``` **Step 2** Replace each of the older line cards with a N9K-97xxx-GX line card as explained in the Installing or Replacing a Line Card. **Caution** Be sure that any line cardslots left empty after this replacement are filled with blank modules (N9K-C9500-LC-CV). **Step 3** Replace the N9K-C9504-FM or N9K-C9504-FM-E/E2 fabric modules with N9K-C9504-FM-G fabric modules in fabric module slots FM 2, FM 3, FM 4, and FM 6 as explained in the Replacing a Fabric Module. Also see the Cisco Nexus 9500 Platform Line Cards and Fabric Modules Data Sheet **Note** You have the option of hot swapping these fabric modules during operations. **Caution** If slots FM1, FM3, or FM5 are left empty, fill them with blank modules (N9K-C9504-FM-G-Z) if available. Slots FM2, FM4, or FM6 must be filled with fabric modules in order to power the fan trays outside those fabric slots. **Step 4** Replace the fan modules with N9K-C9504-FAN2 for the N9K-C9504-FM-G fabric modules. **Step 5** Enter the write erase command at the command line and press y when prompted whether to proceed. ``` switch# write erase Warning: This command will erase the startup-configuration. Do you wish to proceed anyway? (y/n) [n] y ``` **Step 6** Reload the switch by using the reload command and enter y when prompted to confirm the reboot. ``` Switch# reload WARNING! there is unsaved configuration!!! This command will reboot the system. (y/n)? [n] y ``` **Step 7** During the bootup, configure the switch by using the setup option. For configuration information, see the Cisco Nexus 9000 Series NX-OS Fundamentals Configuration Guide. **Step 8** Copy the old configuration from the bootflash to the new configuration by using the copy command. ``` switch# copy bootflash:backup-config running-config ``` **Step 9** Copy the running configuration to the startup configuration by using the copy running-config startup-config command. ``` switch# copy running-config startup-config ``` **Step 10** If there is a configuration that requires a switch reload, reload the switch by using the reload command and enter y when prompted to confirm the reboot. ``` Switch# reload This command will reboot the system. (y/n)? [n] y ```
