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:

The Vess R2000 ships with a full set of new cables, as required for each specic 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.
seriAl cOnnectiOns
Vess uses a serial connection for the command line interface (CLI). After you set the IP address, you can access
the CLI through a network connection, also. Normally, users prefer WebPAM PROe because of its graphic user
interface. But the CLI can do the same jobs. And it works when your network connection is down.
For Vess, you must use the CLI to set the Management Port IP address in order for WebPAM PROe to connect
with it. See “Making a Serial Connection” on page 298 and “Setting-up the Serial Connection” on page 66 for
more information on making the connection. This issue is discussed further under Network Connections, below.
The CLI controls and manages but does not move data. The CLI communicates through a RJ11-to-DB9 serial
data cable, supplied with the Vess. You may choose not use the CLI 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.
