• To install a new feature image or patch image in standalone mode, you must install it on the active
MPU first. To upgrade an image, you must upgrade the image on the standby MPU first.
• To install an image in IRF mode, you must install the image on the master first. To install an image
on a member, you must install the image on the active MPU first.
• To upgrade an image in IRF mode, you must upgrade the image on one subordinate member first.
To upgrade an image on a member, you must upgrade the image on the standby MPU first.
• When you install or upgrade a software image on the active MPU in IRF mode, the system
automatically installs or upgrades the software image on the LPUs and switching fabric cards as
needed. You do not need to install or upgrade the software of the LPUs and switching fabric cards
separately.
• To upgrade multiple images for a slot, you must activate all of them using a single install activate
command.
• For an incremental upgrade, you must confirm the software changes to keep activated images
effective after a reboot. However, you do not need to confirm software changes for a reboot or ISSU
reboot upgrade, because the install activate command changes the startup software image sets.
