• The directory structure that stores the image and configuration files is divided
into two parts:
• The certified directory contains files that have been certified by an
authorized user as the default files for the switch.
• The working directory contains files that may or may not be modified
from the certified directory. The working directory is a holding place for
new files. Files in the working directory must be tested before you
commit them to the certified directory.
1 Choose Administration→NE Maintenance→Software Upgrade from the 5620 SAM
main menu. The Software Upgrade form opens.

a If you need to upgrade the image files or the image and boot files, go to

c If you need to upgrade the FPGA files, go to step 30.
3 Choose the appropriate software upgrade policy.
4 Click on the Software Images and AOS Software tabs.
5 Choose a software image in the list.
6 Click Transfer to Sites. A list of NEs opens. The list is filtered to display only the
device type that is appropriate for the selected software image.

8 Click OK. The selected software image file is uploaded to the working directory of
the selected NEs.
9 Click on the Software Upgrade Status tab to view the status of the upgrade as it

Note 1 — To perform an ISSU, use the software upgrade window only.
Note 2 — The OS 6400, OS 6850E, OS 9700E, OS 9800E, and OS 10K
support standard software upgrades in addition to ISSU. On an
OmniSwitch, the introduction of new images requires a system reload
which disrupts all data traffic during the reload process. Data traffic
loss is limited to L3 base routing instance traffic; no loss of Layer 2 data
traffic should occur.
Note — The 5620 SAM performs the upgrade according to the
configuration in the software upgrade policy that is assigned to the NE.
