Patch installation task list
Task Remarks
Installing patches:
• Installing and running patches in one
step
• Installing patches step by step
IMPORTANT:
If patches are released in a package, you must use the one-step
installation method.
If patches are released in separate patch files, you can use either
method. One-step installation is fast and easy to use. In contrast,
step-by-step patch installation allows you to control the patch
status.
Uninstalling a patch step by step Optional.
Installation prerequisites
To ensure a successful patch operation and normal device operation after patch installation:
• Use the release notes to verify the following items:
{ Patch release method. If patches are released in a package, you must choose the one-step
installation method to install patches.
{ Compatibility of the patch file or patch package file you are installing with the device model,
card type, and software version.
• Save the patch package file to the root directory of each MPU's storage media. If patch files are
used, save the patch files as follows:
{ Save the patch files for the active MPU, interface cards, or switching fabric modules to the root
directory of a storage medium on the active MPU. The active MPU must be in the same chassis
as the interface cards and switching fabric modules.
{ Save the patch files for the standby MPU to the root directory of a storage medium on the
standby MPU.
