SERVSWITCH™ DUO AND SERVSWITCH™ QUADRO
3.5 Powering the Duo/Quadro
NOTE
Before powering on the Duo/Quadro, make sure that the two positions
of the DIP switch on the Duo’s/Quadro’s rear panel are both set to OFF.
Once you’ve installed your ServSwitch Duo/Quadro system and attached your
equipment to it, you need to apply power to each Duo/Quadro in the system. You
can use just the single power supply that came with the Duo/Quadro, or you can
purchase a second one separately (product code PS649) and plug them both in to
create a redundant power system.
Plug each power supply’s output cord into one of the power jacks labeled “A”
and “B” on the back of the ServSwitch Duo/Quadro. (These power inlets are both
the same; you can use either one to power the Duo/Quadro.) Attach the input
cord to the power-supply transformer’s IEC 320 inlet, then plug the input cord
into utility (mains) power. If you’re using two power supplies, plug them into
separate outlets but
don’t plug them into separate circuits unless the circuits use the
same electrical phase and the same ground; differences in phase or grounding
between electrical circuits could damage the Duo/Quadro.
As you plug in each Duo/Quadro, it should start operating immediately; the
Duo/Quadro has no ON/OFF switch. Depending on which power jack(s) you’ve
attached a power supply to, either the “POWER A” LED, the “POWER B” LED, or
both will light. The on-screen display should also pop up on the monitors at your
user stations (see
Section 4.2
).
The power LEDs on the front panel of the Duo/Quadro indicate the voltage
that’s being supplied to each power inlet. If POWER A or POWER B is lit, a
working power supply is connected to the corresponding inlet. If you have two
working power supplies connected, you can disconnect and reconnect either one
of them without disturbing the Duo’s/Quadro’s operation.
Always apply power to any ServSwitch Duos/Quadros
first
,
then
power on each of
your monitors and computers; if you power up the computers before the Duos/
Quadros, the computers might not recognize the presence of the mouse or
keyboard.
