Updating IPMI and BIOS firmware

This procedure describes how to use CLI commands to update IPMI and BIOS firmware on the Network Security appliance.

Note
The NX 2550 model requires an update to IPMI 3.11 and BIOS 1.9. You must update the IPMI before you update the BIOS.

Updating IPMI firmware

To update the IPMI firmware:

Caution
IPMI network and password settings revert to factory defaults after this upgrade, and IPMI logs are deleted. Make a note of your settings and back up your IPMI logs.

Warning
Do not shut down or remove power from the appliance during the update.

Go to CLI configuration mode.

hostname> enable
hostname# configure terminal

Check the version installed on the appliance:
```
hostname (config) # show ipmi
```

Begin the update:

hostname (config)# ipmi firmware update latest

Confirm the update:
```
hostname (config)# show ipmi
```

If the update fails, try the steps again.

If IPMI functions are not fully restored, perform a full power cycle (cold shutdown) on the appliance:

Stop the reload process:
```
hostname (config)# reload halt
```
Disconnect all power cables for two minutes.
After two minutes, reconnect power cables and restart the appliance.

Updating BIOS firmware

Important
Make sure the IPMI firmware is updated before you perform this procedure.

To update the BIOS firmware:

Go to CLI configuration mode.

hostname> enable

hostname# configure terminal

Check the installed version:
```
hostname (config) # show system bios
```
Begin the update:
```
hostname (config)# system bios firmware update latest
```
Caution
Do not shut down or remove power from the appliance during the update.
Confirm the update:
```
hostname (config)# show system bios
```
Stop the reload process:
```
hostname (config)# reload halt
```
Disconnect all power cables for two minutes.
After two minutes, reconnect power cables and restart the appliance.
