Operation
In operation, the ServSwitch Secure USB unit allows you to quickly and securely
switch between up to four systems. Strictly only one system may be accessed at
a time, whereupon the common keyboard and mouse are linked to that system.
Selecting computers
In order to guard against the possibility of malicious software and also to
minimize the chance of accidental switching, the ServSwitch Secure USB unit
offers only one method to change between channels. All switching is done using
the front panel switches.
Error indicator
The red error indicator is located on the right side
of the front panel and is labeled ERR. Separate
microprocessors monitor each channel and any
of them can trigger an error state if they detect
unexpected or unauthorized operations. If the ERR
indicator illuminates, you will need to first locate and
confirm the source of the fault. Then you will need to
either power cycle the offending computer or remove
and replace its USB connection to the ServSwitch
Secure USB.

• The buttons are clearly labeled to eliminate any ambiguity.
• Press the appropriate button to select the labeled channel.
• When the chosen channel has been connected, the adjacent indicator
will illuminate (continuously) to confirm. If the indicator flashes, then the
selected computer is either switched off or disconnected.
• Each channel uses a differently colored indicator to provide additional visual
feedback about the chosen channel. Channel 1 has a green indicator and
is generally configured to link with the lowest security computer/network,
whereas channel 4 (or channel 2 on two-port versions) has a red indicator
and is generally configured to link with the highest security computer/network.
Note: If a keyboard key is held down during a channel change then the key will
be sent to the selected computer upon release of the channel change button.
Do not hold down keys during a channel change.

Tamper-evident seals
The primary casing access screws are pre-fitted with tamper-evident seals. It
may be a policy of your organization to fit proprietary tamper-evident labels
across certain chassis screws. Additionally, seals could be added between each
connection and the unit to highlight any connections that have been altered.
IMPORTANT: Do not use the unit if the tamper-evident seals are
damaged. Do not use if there are any signs of damage to the unit or its
power supply.
