Web Administration Tool
The Web Admin tool may be accessed by typing the IP address of
your DriveStation FlexNet into the URL bar of a browser running
on a computer connected to the same network as the DriveStation
FlexNet.
Or, from your DriveNavigator CD, click Options.
Choose Browse settings page to open the Web Admin tool.

Welcome to your DriveStation’s Web Admin tool! Bookmark this page in your browser so it can be
easily accessed for future conguration changes. If the DriveStation FlexNet’s IP Address changes,
you will need to recreate the link. You can also get here by typing http://DriveStation_Name into a
Web browser, where DriveStation_Name is the name (hostname) of your DriveStation FlexNet.
You are now at the Home screen. You can navigate this menu by clicking on the links at the left
of the screen. Here at “Home”, you can see basic information about your DriveStation’s current
conguration. To exit Web Admin, close the browser window.

You may modify your DriveStation FlexNet’s
hostname in the Hostname window. A friendly,

recommended.
Make sure that the date and time are correct
in Date and Time Setup. To synchronize time
settings with those in your computer, press
Use Local Time. To have your system time
automatically set by an NTP server, enable NTP
Server and enter an IP Address for an NTP server
(e.g. 192.43.244.18) or click on the box below to
use the supplied default NTP server.
Ensure that the Display Language is set to a
language that you’re comfortable with.
Click Apply to save your settings.

Network Settings
In most networks, DriveStation will get its IP Address
automatically from a DHCP server. You may disable DHCP
here if you would rather set a static IP address manually.
If DHCP is disabled and an IP Address is not set manually,
it will default to 192.168.11.150 with subnet mask
255.255.255.0. In that case, change your PC’s IP address
to 192.168.11.xxx and subnet mask to 255.255.255.0 to
access the DriveStation or use the DriveNavigator Wizard.
The DriveStation FlexNet’s IP Address, Subnet Mask,
Default Gateway Address, and DNS Server address may all
be entered manually under IP Address Properties.
Click Apply after making any changes.

14
Sleep Mode
To save power, the DriveStation can be set to go into sleep
mode after 10 - 60 minutes of inactivity. The sleep mode
setting only works when the DriveStation is connected via
LAN. To use sleep mode while the DriveStation is in USB
mode, install the eco manager tool, located in the Tool/eco
folder of your CD.

15
Disk Management
Here, you may initiate a disk check that
scans your DriveStation’s hard drive for
errors. Also, you may reformat the hard
drive from here. Reformatting the drive
erases all data from the drive, so make
sure that your backups are up to date
before reformatting the drive.

16
Security
To enable password protection on the admin account, enter
a password twice and click apply. Once the admin account
is password protected, you may password protect your
shared folder as well.

17
Maintenance
Reset restores all settings to their factory defaults. Your
data isn’t affected.
Check www.buffalotech.com for updated rmware les.
To update the rmware, browse to the updated rmware
le and click Upload.
You may also reset the DriveStation’s settings to factory defaults by holding down the reset
button on the back of the unit during startup. Hold down reset, turn the unit on, and continue

Notes on Use
With a LAN connection, the maximum le size is 127 GB. Files larger than 4 GB
will not be accessible from the USB interface.
If no DHCP server is available, the IP address of the device will default to
192.168.11.150. In that case, change your PC’s IP address to 192.168.11.xxx to
access the DriveStation or use the DriveNavigator Wizard.
When in LAN mode, up to 8 clients can access the drive at the same time.
Do not switch between USB and LAN modes during le access. A blinking Power/
Access LED can indicate le access.
With a USB connection, the maximum le size is 4 GB.
If your PC can not reboot properly after installing the software package, uninstall
the sleep mode control software to resolve.
Before changing from USB mode to LAN mode, use the ‘Safely Remove Hardware’
wizard to disconnect the USB connection properly.
The SecureLockMobile utility is stored in the shared folder of the drive. It’s also
on the CD at \Tool\SLM\slm.exe. SecureLockMobile works with both USB and
Ethernet connections.
The power save utility on the CD is for USB connection only. Use the power save
settings in the web admin to set power settings in LAN mode.
