To connect a console to the switch, use the RJ-45 console cable shipped with
the switch. Alternatively, you can use a USB cable (not supplied) for a console
connection. (See "USB Console Port Notes" below.) Connect a PC or VT-100
terminal to either of the Console ports. The connected PC or terminal then
functions as a management console connected directly to the switch.
The switch can simultaneously support one out-of-band console session,
through one of the console ports, and in-band Telnet console sessions. The
console ports are used only for out-of-band management, not for Telnet
sessions.
USB Console Port Driver Download. When using the USB Console
■
Port, the connected PC first requires "virtual COM port" USB drivers to
be installed.
USB drivers are available for Windows XP (SP3 or later), Windows Vista
(SP2 or later), and Windows 7 (SP1 or later). The drivers can be found on
the HP Web site at www.hp.com/networking/support. On that web site,
follow these steps:
Type your product model (for example, 2920), or product number in
1.
the Auto Search text box.
2. Select one of the switches from the drop down list.
Click the Display selected button.
3.
4. From the options that appear, select Software downloads (on the right-
hand side). Then, download the "USB Console Port Drivers and
Information".
Your PC's operating system may also automatically find the correct driver
when it detects the switch USB connection.
■ USB Console Port and RJ-45 Console Port Interaction. Note that
you cannot use both the RJ-45 and USB console ports at the same time.
By default, the RJ-45 console port is active (to allow remote access to the
switch via a terminal server). But, when the USB console port is connected
to the switch and then to a live PC, it takes priority over the RJ-45 console
port and becomes the active port. If the USB console session is closed by
the inactivity timer, though, the RJ-45 console port becomes active again.
To reactivate the USB console port, make sure that the USB console cable
is connected to a live PC and then simply unplug it from the switch and
then reconnect it to the switch. If desired, you can configure the inactivity
timer to a longer time via the terminal emulation program that you are
using.
