SERVSWITCH™ SPECTRA
• It can scan (switch back and forth between)
between the two CPUs every 1 to 15 seconds.
• Its “screen saver” function can turn off idle
video after 1 to 999 seconds.
• Advanced users can program the keyboard’s
typematic rate and delay.
• Some settings for each CPU can be permanently
saved in nonvolatile memory.
• A mounting plate is included for permanently
surface-mounting the Spectra.
2.3 The External Controls, Indicators, and Connectors
There’s a pushbutton on the top of the ServSwitch
Spectra that you can press to switch between the two
CPUs. There’s also a pair of LEDs on the Spectra’s front
panel labeled with the Roman numerals “I” and “II”
that
tell you whether the corresponding
CPU is selected
(“I” for CPU 1, “II” for CPU 2).
All cable connections are made at the ServSwitch
Spectra’s rear panel, which also holds the Spectra’s reset
switch. To familiarize yourself with the Spectra’s rear-panel
components and what they’re used for, refer to Figure 2-1
and the descriptions that follow on the next page.
