4. Click Upgrade Adapters to start the upgrade procedure.
If you enabled Check Adapter Firmware Version, the current firmware
level(s) are compared with that of the upgrade versions. If the current
version is equal to, or higher than the upgrade version, a message
appears in the adapters Progress column informing you that no
upgrade is available and stops the upgrade procedure.
If you didn't enable Check Adapter Firmware Version, the upgrade
files are installed without checking what their level is.
When the procedure completes the new adapter firmware version
displays.
Note: 1. The switch may work with older adapter firmware versions, but for
optimum compatibility we recommend upgrading your Adapter
Cable firmware to that stored with the switch's Main firmware.
2. You can perform the upgrade procedure anytime you add an Adapter
to the installation to make sure it is working with the latest firmware
version.
3. To recover from a "failed upgrade" situation, see Adapter Firmware
Upgrade Recovery, page 154.
