SERVSWITCH DUO™
5. Operation
This chapter explains the general operation of the ServSwitch Duo. We
recommend that you read this chapter carefully before starting to use the Switch;
also make sure you have read the important note on page 20.
5.1 Power Status
At power-up, the ServSwitch Duo selects CPU channel #1 and displays “1” unless
a password has been set. If a password has been set, the Switch will display “P” and
remain locked until a valid password is entered. The 12- and 16-port models will
also light their Power LED.
5.2 The Status LEDs
The green CPU-status LEDs numbered 1 through n (where n is the total number
of CPU ports—4, 8, 12, or 16—on the Switch) show the ON/OFF status of the
computers connected to the corresponding CPU ports. This status is derived from
the computer’s keyboard connection and operates even when the ServSwitch Duo
is powered off. See also the “PC bootup sequence” paragraph in Section 5.6.
The red status LEDs (A and B) show the activity status of the local and remote
keyboard/monitor/mouse control ports. When port A is active, port B is disabled,
and vice versa. When the Switch is idle, it activates one of these ports and lights the
associated LED when it detects keyboard or mouse activity on that port. When no
keyboard or mouse data has been detected on the active port for the duration of
the switchover-timeout period (see Section 4.2.4), the port becomes inactive, its
LED goes out, and the other control port can then be used.
5.3 The Front-Panel Pushbuttons and the Remote-Control Module
SELECT key and Remote-Control Module
You can use the SELECT key to select which CPU channel (CPU port) is currently
controlled by the active control port. Press the key once during normal operation
to select the next CPU channel in sequence (for example, to select channel 6 if
channel 5 is currently selected); press the key repeatedly to manually cycle through
the channels.
You can also use the SELECT key to access the ServSwitch Duo’s configuration
mode (see Section 4.2.1). To access configuration mode while the Switch is
operating, press the SELECT key and hold it down for 5 seconds until “C” appears
on the Switch

s front-panel display.
