From the keyboard you can go forward or backward through the ServSwitch’s ports
by selecting either the next or the previous port respectively. To switch to the next
port, press and release the left Control Key ([CTRL]), then press the plus key (the
key at the top of the keyboard marked with [=] and [+]). To switch to the previous
port, press and release [CTRL], then press the minus key (the key at the top of the
keyboard marked with [-] and [_]). The command is not case-sensitive. Do not use
the [+] and [-] keys on the keyboard’s numeric pad; the ServSwitch doesn’t
recognize these.
You can also select the next port manually from the ServSwitch’s front panel by
pushing the button labeled NEXT. Each time you press the button, the next port
in sequence is selected. You cannot select the previous port from the Switch’s front
panel without cycling through all the ports.

To enable scanning (switching from CPU to CPU in a continuous rotation) from
the keyboard, press and release the left Control Key ([CTRL]), then press [S]. The
ServSwitch will begin scanning sequentially from its currently selected port
through the higher-numbered ports, then begin again at CPU Port 1. As it scans, it
delays 1 to 15 seconds at each port. (This “Scan-Delay Time” is user-selectable; see
Section 4.3.5
.) To stop scanning, press and release [CTRL], then press [X]. You
can also disable scanning by entering a Select Port command. ServSwitch letter
commands are not case-sensitive: You can enter upper- or lower-case letters. To
enable scanning from the front panel of a single or master ServSwitch, use the
SCAN button (see
Section 2.3
).
