Configuration Prerequisites
Patches are released per device model or card type. Before patching the system, you need to save the
appropriate patch files to the storage media of the device using FTP or TFTP. When saving the patch
files, note that:
z
The patch files match the device model and software version. If they are not matched, the hotfixing
operation fails.
z
Name the patch file properly. Otherwise, the system cannot locate the patch file and the hotfixing
operation fails. The name is in the format of "patch_
PATCH-FLAG suffix
.bin". The PATCH-FLAG
is pre-defined and support for the PATCH-FLAG depends on device model or card type. The first
three characters of the version item (using the
display patch information
command) represent
the PATCH-FLAG suffix. The system searches the root directory of the storage medium for patch
files based on the PATCH-FLAG. If there is a match, the system loads patches to or install them on
the memory patch area.

The loading and installation are performed on all cards that are in position and OAM CPU, so before
these operations, save the patch files for the active main board (AMB) and interface card to the root
directory of the AMB's storage medium, and save the patch files for the standby main board (SMB) to
the root directories of the SMB's storage medium. Make sure the patch files saved on the AMB and
SMB are the same. (On the SR6604/6608/6616 router)
