Connection problems include:
• "Serial Connections" on page 216
• "Network Connections" on page 216
• "SAS Connections" on page 217
• "Browser Does Not Connect to ASUS Storage Management" on page <?>
Connection problems cause a majority of failures in almost any electrical system. While the installation of the
cables and components was correct, they don't function properly, or at all, because:
• A connector is dirty or corroded
• A connector is loose or damaged
• A cable looks OK outside but has an open circuit inside
• The wrong cable was used
ASUS DS300f G2s ship with a full set of new cables, as required for each specific model. Be sure to use
these components because: 1.) They are the proper ones for your RAID subsystem, 2.) They are in brand-new
condition, and 3.) You paid for them with the purchase of your subsystem.

ASUS DS300f G2 uses a serial connection for the command line interface (CLI) and the command line utility
(CLU). After you set the IP address, you can access the CLI and CLU through a network connection, also.
Normally, users prefer ASUS Storage Management because of its graphic user interface. But the CLI and CLU can
do the same jobs. And they work when your network connection is down.
For ASUS DS300f G2, you must use the CLI or CLU to set the Management Port IP address in order for
ASUS Storage Management to connect with it. See "Setting-up the Serial Connection" on page 35. This issue is
discussed further under Network Connections, below. See "Making Serial Cable Connections" on page 29for more
information on making the connection.
The CLI and CLU control and manage but they do not move data. They communicates through a RJ-11-to-DB9
serial data cable, supplied with the ASUS DS300f G2. You may choose not use the CLI or CLU often and want to
disconnect and store the cable. Consider leaving it connected, so you know where it is the next time you need it.

Each RAID controller has an Ethernet (RJ45) management port connector on the back of the enclosure. This
is a Gigabit Ethernet connector designed to connect to your network. The ASUS DS300f G2 becomes a node on
your network like any other PC, server or other component with an IP address.
ASUS DS300f G2 ships from the factory IP addresses of 10.0.0.1, 10.0.0.2, and 10.0.0.3. You must change
these addresses to ones that work on your network. You make the initial IP address setting using the CLI or CLU.
See "Setting-up the Serial Connection" on page 44.

Note that ASUS DS300f G2's virtual and maintenance ports can accept IP address assignments from a DHCP
server. Use ASUS DS300f G2's Command Line Utility (CLU) to enable this feature.
If you manually assigned an IP address to the ASUS DS300f G2 but there is a DHCP server on your network,
there is a chance that the server might assign the ASUS DS300f G2's IP address to another node. You might see
a warning to this effect on your PC's monitor. If this happens, ASUS Storage Management may not be able to
connect. See your network administrator to work out a suitable arrangement.
