Powering On
When you power on, reset, or power cycle the ATEN Secure KVM Switch, the switch will perform a
self-test to check the unit's integrity and security functions.
During the self-test
� All Port and CAC LEDs will turn ON and then OFF.
� The KVM focus will be switched to port 1 when the self-test completes successfully (port 1 LED
lights bright orange).
Self-test failure
In the case of a self-test failure, the Secure KVM Switch becomes inoperable, with front panel LED
combinations indicating the potential cause of the failure (such as a button jam or KVM integrity
compromise)
� A pre-defined combination of port and CAC LEDs indicate the cause of the failure.
� If all front panel LEDs (except the Power LED) flash continuously, it means KVM tampering is
detected or a self-test failure has occurred (except for Pushbutton jam; see below)
� If Pushbutton jam is detected, both the port's LEDs will flash.
For security, the ATEN Secure KVM Switch becomes inoperable if a self-test fails. Please verify your
KVM installation, pushbuttons, and power cycle the Secure KVM Switch if this should happen. If the
self-test failure remains, stop using the ATEN Secure KVM Switch immediately, remove it from
service and contact your ATEN dealer.
After the ATEN Secure KVM Switch is powered on and ready, power on your computers. By default
the ATEN Secure KVM Switch will switch to port 1 after a successful self-test.
The ATEN Secure KVM Switch filters and emulates both a mouse and keyboard on each port after the
unit is powered on. If the keyboard, mouse, monitor, or Smart card / CAC reader fails to operate
properly, make sure that you are using the appropriate peripherals (qualified and authorized
peripherals); then power off the ATEN Secure KVM Switch, check all the cable connections, and
power on the unit again.
