3.2 Upgrading the Firmware
Updating OS firmware will accommodate new functions or bug-fixes. Once you get new releases of
an OS firmware image, you can upgrade the OS firmware by using the web browser. The process is
simple and fast. Once you get the image file of the new OS firmware from your vendor, open the
Administration Homepage of the NAS server and select the Server→Upgrade menu. Specify the
full path of the image file or click the Browse… button to find it. Click Apply to begin. The process
might take several minutes. The server will reboot after the firmware is upgraded.

17
3.3 Shutting Down the Server
Shutdown, reboot and startup actions
The NAS server can be shut down by pressing the power button twice at the front of the server case. The whole shutdown
process might take seconds to minutes until data are all safely saved to the hard disks. To shut down the server from the
Administration Homepage, select Shutdown from the Server menu and click the Reboot or Shutdown button.
You can specify the actions to take during the next startup.

3.4 Enabling UPS Support
The NAS server supports UPS and basic power management functions. It sends alerts when there are power events like
utility power failure or low battery capacity. When power events occur, the NAS server can shut down itself automatically
to prevent potential data loss.
To use smart-signaling UPS, connect UPS to the NAS server with an RS-232 or USB cable. Then go to the Server UPS
Settings menu on the administration page to enable UPS support.
To use network-type UPS, connect the UPS to the LAN first. Then go to the Server UPS Settings page on the
administration page. Enable APC Smart UPS series、USB UPS、Generic serial UPS Type 1 and Type 2, select Network
UPS from the UPS Type menu and enter the UPS IP address and correct community.
Below are the shutdown options on the page.
Shut down immediately
when battery is low
Specify whether to shut down the server when UPS battery is low.
Note:
When utility power fails, the NAS server will always shut down.
Shut down in x minutes
when AC fails
Specify how many minutes to wait before shutting down the server
when a power event occurs.
Turn off UPS when shut
down by power failure
If checked, the NAS server will turn off the UPS while it is shutting
down by power failure. If not, the UPS will still be working when the
server is shut down.

19
3.5 Modifying the Administrator’s Password
Admin is a built-in user account for the administrator. It is like the root account in UNIX or the administrator account
in Windows 2000 or XP. Using this account, users have access to the administration homepage and all the storage
resources. By default, the password for this user account is empty. To prevent security vulnerability, it is strongly suggested
to specify the password when performing the first-time setup of the NAS server.
To specify or modify the administrator’s password, please select the Server→Password menu on the administration
homepage. Input the current admin password in the Old Admin Password field, and the new password in the New
Admin Password and Confirm Admin Password fields. Then click Apply.
The administrator can delegate the administrator’s privilege to other users by including them into the Admins built-in
group. Please select the Security→Account menu. Select Admins* in the Local User/Group window and click
Property. Specify the users to have the privilege and click Apply.
