SERVSWITCH™ PROFESSOR
ServSwitch Professor System Control Modules (SCMs) should always be set to an
address of 255 (all DIP-switch positions up, the factory-default setting for SCMs),
and there should only be one SCM in a Professor system. Address 0 (zero, all
positions down) is reserved for diagnostic purposes. So Professor Student Modules
(STMs) should be set to addresses between 1 and 254. (The factory-default address
for STMs is “1.”) Here are the DIP-switch settings for the STM addresses up to 10:
• Address 1 = position 8 up;
• Address 2 = position 7 up;
• Address 3 = positions 7 and 8 up;
• Address 4 = position 6 up;
• Address 5 = positions 6 and 8 up;
• Address 6 = positions 6 and 7 up;
• Address 7 = positions 6, 7, and 8 up
• Address 8 = position 5 up;
• Address 9 = positions 5 and 8 up; and
• Address 10 = positions 5 and 7 up.
One note of caution: If you set two units to the same address, their LEDs will blink
rapidly when the system is powered up. But if you accidentally set the address of a
System Control Module to something other than 255 and set a Student Module to
address 255, the SCM will no longer recognize most commands, but the STM will.
So be very careful as you set this value.

ACKMOUNTING
(O
PTIONAL
)
If you want to mount the ServSwitch Professor in a 19" rack, you will need a Mini-
Size Classic-Chassis ServSwitch Family Rackmount Kit (our product code SW727).
If you want to mount the ServSwitch Professor in a 23" or 24" rack, call Black Box
Technical Support for a quote on a special Kit. See
Appendix C
for more
information.
