Problem Troubleshooting
When connecting a
serial interface adapter
to a server running Red
Hat Linux or SLES, the
numeric keypad keys
on a PC keyboard do
not map to VT100
emulation under the
Linux shell. Using the
numeric keypad with
the vi text editor causes
function characters to
appear rather than
numbers.
Use the "printenv" command to show the TERM assigned under Linux. It can be
matched appropriately with other termcap entries by editing the profile or setting the
TERM equal to "ansi". For PC keyboards, ANSI is the most compatible emulation.
-or-
Edit your /etc/inittab as
s0:2345:respawn:/sbin/agetty -h ttyS0 115200, 9600 ansi
Where ttyS0 is the serial device name under Linux where the serial interface
adapter is connected.
Then at a shell prompt, enter init q, or reboot the system.
Virtual Media is not
working properly.
Be sure that you are using the following:
•
HP IP Console Switches with Virtual Media or HP Server Console Switches with
Virtual Media
•
A USB 2.0 interface adapter with Virtual Media, or a PS2 interface adapter with
Virtual Media server and an operating system that supports high-speed
composite USB 2.0 devices
You must be able to see a Virtual Media CD drive and a mass storage drive on the
target server to be able to map a local resource to the remote server.
Virtual Media is
responding slowly.
See "Using Virtual Media (on page
The local user cannot
map a USB composite
media device.
See "USB composite media devices ("

The keyboard does not
respond after opening
a Virtual Media
session.

Options in the Virtual
Media dialog box are
not available.
See the "Configuring Virtual Media parameters" section in the HP IP Viewer User
Guide.
The video resolution is
distorted.

The console switch offers optimum video performance when the distance between the server and console
switch is 22.9 m (75 ft) or less at video resolutions 1280 x 1024 at 75 Hz. The system is capable of
operation at distances up to 30.5 m (100 ft) at reduced video resolutions 800 x 640 at 60 Hz, worst
case.
