A. In order to upgrade the firmware for NSS4000/6000, follow these steps:
- Go to www.cisco.com/support and download the firmware for the specified model, in this case, NSS4000/6000.
Note: Do not extract the firmware once it is downloaded.
- Login to the web interface of the storage device.
- Fill in the administrator login information:
Default username is admin.
Default password is admin.
- Once the login is successful, click Admin.
- Next, click Maintenance. The System Details page displays:
- Click the Browse button to choose the firmware that was previously downloaded.
- In order to start the firmware upgrade, click the Upgrade Firmware button. A warning message pops up.
- Read the warning message and click the OK button to continue with the firmware upgrade.
- You see the progress screen within two minutes.
Note: Do not interfere with the firmware upgrade process. The unit reboots automatically when the firmware upgrade is complete.
- In order to determine if the firmware upgrade has been completed, check for the last entry: Firmware update succeeded. The system will reboot now.
- Wait for the system to reboot. Do not power cycle the unit.
- Check the activity of the Power LED. Within the process of the upgrade, the Power LED alternately blinks yellow and green. This process can take about four minutes.
- Then, the system reboots. The Power LED blinks green on shutdown and on startup. Eventually, the Power LED appears as solid green again. It is the ultimate indication that the firmware upgrade process has completed.
- The system is ready once the Power LED is back on solid green, and LAN1 or LAN2 is solid.
Note: You possibly lost connectivity to the AD domain after the firmware update on NSS4000. Refer to this check list:
Joined NSS to a workgroup to allow complete disassociation to AD.
Rebooted the NSS.
Rejoined the NSS to AD but failed.
Performed the join again after verification of domain AD account and network settings.
