Operation

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 LEDs, all CAC LEDs (if supported), Num Lock LED, Caps Lock LED, and Scroll Lock

LED on the Secure KVM 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 (on the Secure KVM) indicating the potential cause of the failure (such as button jam or

KVM integrity compromise)

� A pre-defined combination of the Port and CAC LEDs indicate the cause of the failure.

� If all front panel LEDs on the Secure KVM (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 (Port LED and CAC LED) will flash.

For security, the ATEN Secure KVM Switch becomes inoperable if the self-test fails. Please verify

your KVM installation by checking that the front panel pushbuttons are not stuck and then power cycle

the Secure KVM Switch. 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.
