SERVSWITCH™ WIZARD
5. Operation
This chapter explains how to operate the ServSwitch Wizard. Please read this
chapter carefully before starting to use the Wizard; also make sure you have read
the important note at the start of
Chapter 4 .
5.1 Power Status
At power-up, the ServSwitch Wizard will try to select CPU channel #1 unless
(a) a password has been set or (b) the Wizard isn’t getting enough power to operate
properly. Watch the Wizard’s front-panel 7-segment display, as described in
Figure 5-1: If the Wizard is not receiving enough power, the display will be blank; if
the Wizard can select CPU 1, the display will show “1”; or if a password has been
set, the Wizard will display “P” and remain locked until a valid password is entered.
(For the meaning of this display after power-up, see
Section 5.3 .)
