The EF3015 controllers contain two different USB (universal serial bus) management
interfaces: a
Host
interface and a
Device
interface. Both interfaces pertain to the
Management Controller (MC), and each interface is accessed via its port on the controller
module face plate. The port labeled Host (USB Type A) is reserved for future use, and its
discussion is deferred. This appendix describes the port labeled CLI (USB Type B), which
enables direct connection between a management computer and the controller, using the
command line interface and appropriate cable (see
for USB port locations).

Figure 18. USB Device Connection - CLI Port
The EF3015 controllers feature a USB CLI port used to cable directly to the controller and
initially set IP addresses, or perform other configuration tasks. The USB CLI port employs a
mini-USB Type B form factor, and requires a new cable and additional support, so that a
server or other computer running a Linux or Windows operating system can recognize the
controller enclosure as a connected device. Without this support, the computer might not
recognize that a new device is connected, or might not be able to communicate with it.
For Linux computers, no new driver files are needed, but a Linux configuration file must be
created or modified (see
). For Windows computers a special device driver file,
gserial.inf, must be downloaded from a CD or web site, and installed on the computer that
will be cabled directly to the controller’s CLI port (see
