Upgrade ION 9000 Firmware

Upgrade ION 9000 firmware.

When a physical ION 9000 device is running with ports 9, 10, and 11 connected (no SFP+ inserted in port 12), after you unplug either of the ports 9, 10 or 11 or configure Admin Down or Admin Up, the ports 9, 10, 11 start flapping indefinitely. This issue is applicable on image versions ION-5.4.x and ION-5.5.1.

To resolve this issue, upgrade the ION 9000 to a new software version using the Prisma SD-WAN and upgrade the firmware using the device toolkit command. It is a one-time process and not required for future ION 9000 upgrades.

It is recommended to always begin with port 12 as the first connected port on ION 9000 to avoid this issue. With a 10G SFP inserted on port-12, this issue will not occur.

During the upgrade duration, the interfaces 9-12 will be down and there will be no traffic on these ports. Interfaces 1-8 and 13-16 will be up. It is recommended to upgrade the firmware during the maintenance window.

Upgrade the ION 9000 software using the Prisma SD-WAN web interface.
Upgrade the ION 9000 software to image 5.4.9 or 5.5.3 release on the Prisma SD-WAN web interface. Refer to Schedule Software Upgrade for details. After the upgrade, a standing alarm is raised and can be seen from the device toolkit.
Run the following toolkit command to check if the ION 9000 has an old firmware:
```
# dump standingalarms
						Code		:	 DEVICEHW_ION9000X722FW_OUTOFDATE
						Ident		:	 x722
						Severity	:	major
						Raised		:	 2021-06-03 00:03:08.806 +0000 UTC (1m30.303724271s ago)
						Correlation ID	:	 EbraKYfr
```
The code DEVICEHW_ION9000X722FW_OUTOFDATE in the output indicates that the firmware is out-of-date and needs to be upgraded.
If the Prisma SD-WAN controller is running version 5.5.3, then, after you upgrade the ION 9000 to 5.4.9 or 5.5.3, the standing alarm is seen on the portal web interface. The alarm indicates that you need to upgrade the firmware for the ION 9000 as described in step 2.
Upgrade the ION 9000 firmware using the device toolkit.
1. Log in to the ION 9000 device toolkit.
2. From the toolkit, run the command upgrade-x722-fw.
3. Enter Y to agree with the firmware upgrade procedure.
Verify the upgrade is successful by running the toolkit command dump standingalarms, the standing alarm is cleared if the upgrade is successful.
