Information

 
TitleHow To Upgrade the EXOS Operating System
Objective
Upgrade EXOS to a newer image and install it to a switch.
Environment
  • Summit 
  • BlackDiamond
  • EXOS All
Procedure

Obtain and download EXOS:

  1. Follow the steps in the article link below

Software upgrade procedure:

  1. Download the appropriate EXOS image.
  2. Place the EXOS image on a TFTP server.
  3. Ensure that you are able to ping the TFTP server from the switch from the appropriate virtual router. At least one of ping vr vr-Mgmt <host> or ping vr vr-Default <host> operations must successfully reach your TFTP server before you can proceed. After verifying the TFTP server is reachable, specify that VR when you download the image in the next step.
  4. Type the command download image <host> <filename.xos> <virtual-router>.
  5. Reboot the system for the upgrade to take effect: Type reboot, then when asked if you want to reboot the switch now, type yes.
Additional notes
  • If upgrading a BlackDiamond chassis with two MSMs, then follow the steps above only on the Master MSM – after which it will automatically synchronize with the Backup.
  • It is unnecessary to specify the partition on which to load the new image, because by default it will be downloaded and installed on the non-active partition.
  • If XMODs are utilized in your environment, then install them prior to rebooting.
  • Upgrading via ScreenPlay is not currently supported in EXOS and must be done through the CLI. 

By default, TFTP is used to transfer the EXOS image. The image can also be transferred via SCP or via USB (if the switch has a USB port). See the articles linked below for further details:
