3.4 Powering the Wizard MP
Once you’ve installed your ServSwitch Wizard MP system and the attached devices,
you need to apply power to each Wizard MP. Most basic systems should be able to
get the power they need from the attached CPUs. Some systems will require the
optional PS649 power supply for each Wizard MP, especially if the system (a) runs
cabling for long distances, (b) uses high-resolution video, or (c) is cascaded.
If you’re powering a Wizard MP with the attached CPUs:
Power up the CPUs. The
Wizard MP (which has no ON/OFF switch) might be able to start operating right
away, because it can draw power from the CPUs’ keyboard interfaces. A single
cable connection to a CPU’s keyboard port is usually sufficient to power the Wizard
MP if the cable isn’t more than 5 meters (16.4 feet) long. (If more than one CPU is
connected, you’ll probably be able to use longer cables; the Wizard MP will draw
power intelligently from all of the CPUs.) As you power up your CPUs, watch the
Wizard MP’s 7-segment display as discussed in
Section 5.1
: If it shows the number “1”
or the letter “P,” the Wizard MP will be able to operate using the power it’s getting
from the CPUs, but if it’s blank, the Wizard MP is not receiving enough power, and
you’ll have to either use the power supply or swap in shorter CPU cables.
If you
are
using the power supply:
Plug the power supply’s output cord into the
power jack on the back of the ServSwitch Wizard MP. Then attach its input cord to
the power-supply transformer’s IEC 320 inlet. Then plug the input cord into utility
(mains) power. (Do this
first
,
then
power on the monitor and each of the
computers; if you power up the computers before the Wizard MP, the computers
might not recognize the presence of the mouse or keyboard.) The Wizard MP
should start operating immediately; it has no ON/OFF switch.
