Installing a Core Image
  
  
    
      Once .xos and .xmod files are stored on a network server (see
          Downloading a New Image), download the image to
        the switch using the following procedure: 
     
    
      - 
        Use a login session on the master node of the
          SummitStack to verify which virtual router (VR) connects to your
          server. Use one of the following ping commands to confirm which virtual router reaches
          your server:
        
          ping vr vr-Mgmt host 
ping vr vr-Default host 
         
        At least one of these commands must successfully
          reach your server for you to download the image. After verifying the virtual router that
          reaches your server, specify that virtual router when you download the image.
       
      - 
        Download the new image to the switch using the
            command:
          
        
        
          download image [[hostname | ipaddress] filename {{vr} vrname} | memorycard
            filename] {partition} {msm
            slotid | slot
            slot number}
        
        
          
Note   
If you configure the switch to write core dump
            (debug) files to the internal memory card and attempt to download a new software image,
            you might have insufficient space to complete the image download. If this occurs, you
            will need to move or delete the core dump files from the internal memory. You will be
            asked during the download process if you want to remove these files. For more
            information, see 
Understanding Core Dump Messages.
 
         
       
      - 
        Before the download begins, the switch asks if you want to
          install the image immediately after the download is finished. Enter
            y to install the image after download. 
        
If you enter 
n to install the image at a later time, the image
          is still downloaded and saved to the switch, but you must use the 
install image
          command when ready to install the image.
 
       
      - 
        Install .xmod images to the inactive partition using the same command shown
          above.
      
 
      - 
        After installing the .xos and all .xmod iamges, reboot the switch (see Reboot Options).
