VTrak 15200 User Manual
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
Promise products ship with a full set of new cables and terminators, as required
for each specific product. 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 Promise product.
Serial Connections
Promise products use a RS-232 serial connection for a command line utility
(CLU). Normally, users prefer WebPAM because of its graphic user interface. But
the CLU can do most of the same jobs. And the RS-232 connection will work
when your Management Port connection is down.
For VTrak, you must use the CLU to set the RAID subsystem's initial IP address
in order for WebPAM to connect with it. This issue is discussed further under
Network Connections (below).
The CLU controls and manages but it does not move data. It communicates
through a null-modem cable, supplied with the Promise product. You can connect
a straight-through serial cable, but it will not work for this purpose. If you do not
use the CLU often, you might want to disconnect and store the cable. Consider
leaving it connected, to be sure it will be there when you need it.
Network Connections
The VTrak 15200 has three GbE connectors on the back of its cabinet. The
VTrak becomes a node on your network like any other PC, server or other
component with an IP address. VTrak ships from the factory a Management Port
IP address of 10.0.0.2. You must change this address to one that will work with
your network. You make the initial IP address setting using the CLU, as
mentioned above. You can make subsequent IP address changes using
WebPAM.
Note that VTrak Management Port does not accept IP address assignments from
a DHCP server. If you have a DHCP server on your network, there is a chance
that it will inadvertently assign the VTrak's IP address to another node. You might
see a warning to this effect on your PC's monitor. If this happens, WebPAM may
not be able to connect. See your IT administrator to work out a suitable
arrangement.
