The LED illuminates when the unit is ready.
The LED blinks when the MergePoint Unity switch is booting or an upgrade is in progress.
The LED blinks "SOS" if a fault condition occurs, such as power supply failure (for MergePoint Unity
switches equipped with dual power supplies), elevated ambient temperature or fan failure. The LED will
continue to illuminate amber as long as the failure persists.
IQ and DSRIQ-SRL modules
Typically, IQ modules feature two green LEDs: a Power LED and a Status LED.
The Power LED indicates that the attached module is turned on.
The Status LED indicates that a valid selection has been made to a MergePoint Unity switch.
The DSRIQ-SRL module prevents a serial break from the attached device if the module loses power. However, a
user can generate a serial break with the attached device by pressing Alt+B after accessing the Terminal
Applications menu.
Adjusting Mouse Settings on Target Devices
Before a computer connected to the MergePoint Unity switch can be used for remote user control, you must
either enable Avocent Mouse Sync (see Mouse Settings on page 38) or set the target mouse speed and turn off
acceleration. For machines running Microsoft
®
Windows
®
(Windows NT
®
, 2000, XP, Server 2003), use the
default PS/2 mouse driver.
To ensure that the local mouse movement and remote cursor display remain in sync, mouse acceleration must be
set to “none for all user accounts accessing a remote system through a KVM switch. Mouse acceleration must
also be set to “none” on every remote system. Special cursors should not be used and cursor visibility options,
such as pointer trails, Ctrl key cursor location animations, cursor shadowing and cursor hiding, should also be
turned off.
For more information about setting mouse movement and cursor features for use with Avocent hardware products
and DSView management software, please visit http://www.avocent.com and consult the Mouse and Pointer
Settings guide.
NOTE: If you are not able to disable mouse acceleration from within a Windows operating system, or if you do not wish to adjust the
settings of all your target devices, newer versions of the DSView software include the Tools Single Cursor Mode command available
in the Video Viewer window. This command places the Video Viewer window into an invisible mouse” mode which allows you to
manually toggle control between the mouse pointer on the target system being viewed and the mouse pointer on the client server
running DSView software.
