Manual Upgrade Procedure
Follow these steps carefully to upgrade your S6000 systems:

1. Dell Networking recommends that you back up your startup configuration and any important files and directories to an external media prior to upgrading the system.

2. Upgrade the Dell Networking OS in flash partition A: or B:
   EXEC Privilege Mode
   u p g r a d e s y s t e m [ f l a s h : | f t p : | s t a c k – u n i t < 0 – 5 | a l l > | t f t p : | s c p : | u s b f l a s h : ] [ A : | B : ]

3. In case of a stack setup, upgrade the Dell Networking OS for the stacked units.
   EXEC Privilege Mode
   u p g r a d e s y s t e m s t a c k – u n i t [ 0 – 1 1 | a l l ] [ A : | B : ] If A: is specified in the command, the Dell Networking OS version present in Management unit’s A: partition will be pushed to the stack units. If B: is specified in the command, the Management unit’s B: will be pushed to the stack units. Upgrade of stack units can be done on individual units by specifying the unit id [0-5] or on all units by using all in the command.

4. Verify the Dell Networking OS has been upgraded correctly in the upgraded flash partition.
   EXEC Privilege Mode
   s h o w b o o t s y s t e m s t a c k – u n i t [ 0 – 5 | a l l ]

5. Upgrade the S6000 Boot Flash and Boot Selector images.
   EXEC Privilege ModeDell Networking OS version 9.14(2.11) requires S6000 Boot Flash image version 3.1.1.7 and Boot Selector image version 3.1.0.3. The Boot Flash and Boot Selector images can be upgraded together by selecting all in the command. If the user wishes to upgrade Boot Flash image or Boot Selector image separately, the options bootless-image or boots elector-image needs to be given separately in the command. The booted option is used to upgrade the Boot flash and Boot Selector images to the image versions packed with the loaded Dell Networking OS image. The Boot Flash and Boot Selector image versions packed with the loaded Dell Networking OS can be found using the show os-version command in EXEC PRIVILEGE mode.
   NOTE: The Boot Flash version packed in Dell Networking OS 9.14(2.11) for S6000 system is 3.1.1.7. Upgrade of Boot Flash to version 3.1.1.7 is not mandatory for proper functioning of the system.

6. Change the Primary Boot Parameter of the S6000 to the upgraded partition A: or B:
   CONFIGURATION Mode
   b o o t s y s t e m s t a c k – u n i t [ 0 – 5 | a l l ] p r i m a r y s y s t e m : [ A : | B : | t f t p : | f t p : ]

7. Save the configuration so that the configuration will be retained after a reload using write memory command.
   EXEC Privilege Mode
   w r i t e m e m o r y

8. Reload the unit.
   EXEC Privilege Mode
   r e l o a d
