Chapter 3 – Operation
Powering On
When powering on, resetting, or power cycling IOGEAR 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 case of a self‐test failure, IOGEAR Secure KVM Switch becomes inoperable. Front panel LED combination (on the secure
KVM) lights up, indicating the potential cause to the failure (such as button jam or KVM integrity compromise):
 A pre‐defined combination of Port and CAC LED indicates the cause to the failure.
 If all front panel LEDs on the Secure KVM (except for Power LED) flash continuously, then either 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 and CAC LEDs will flash.
For security, IOGEAR Secure KVM Switch becomes inoperable if self‐test fails. Please verify your KVM installation,
pushbuttons, and power cycle the Secure KVM Switch again if this should happen. If the self‐test failure remains, stop using
the Secure KVM Switch immediately, remove it from service, and contact your IOGEAR dealer.
After the IOGEAR Secure KVM Switch is powered on and ready, power on your computers. By default, the IOGEAR Secure
KVM Switch will switch to Port 1 after a successful self‐test.
Resetting the Secure KVM Switch
Press the Reset button on the front panel to reset IOGEAR Secure KVM Switch.
When pressing the Reset Button for more than 5 seconds, the keyboard/mouse buffer will be purged. Then, the IOGEAR
Secure KVM Switch will reboot and a self‐test will initiate. After a successful self‐test, the port focus will be switched to Port
1, and the CAC function of each port will be set back to factory default (enabled).
If the Secure KVM fails to generate video on the console monitor after a reset, please power off all connected devices,
check the cables, and follow the Operation Instructions in the User Manual to power on the installation.
Manual Switching
For increased security, IOGEAR Secure KVM Switch offers manual port‐switching only. This is achieved by pressing the port
selection pushbutton located on the Secure KVM switch's front panel or on the RPS if connected and aligned. Press and
release a port selection pushbutton to bring the KVM focus to the computer attached to its corresponding port (see Port ID
Numbering below). To meet maximum security and channel isolation requirements, the keyboard, mouse, monitor, audio,
and USB CAC reader ports will be switched together.
The Selected Port LED lights orange to indicate that the computer attached to its corresponding port has the KVM focus
(keyboard, mouse, monitor, audio, and CAC reader).
The PC that has the port focus on should be able to detect the peripherals after port switching. If the PC fails to detect the
keyboard, mouse, or CAC reader:
