Polycom QSX 3725-22370-001/B - Manual (Page 22)

After the MGC call has connected to the QSX, the QSX unit will not connect to any other
QSX or video units. Other non-QSX units must access the content via the MGC bridge.
If the QSX is already in a call with another unit (i.e. – QSX or video unit) and the MGC
calls it, it will reject the MGC call.
Note: It is strongly recommended that you only use the MGC’s dial-out mode for
connecting to the QSX. Doing so avoids establishing a QSX-to-QSX connection before a
connection between the QSX and MGC is established. If this happens, the MGC dial
attempt will be rejected.
Note: When participating in an MGC-hosted meeting with a VTX 1000 conference
phone, you will only see two parties on the QSX unit’s Info Screen—you and the MGC.
If you see more meeting participants, you should hang up the call and use the VTX 1000
to manually dial into the MGC unit again.
Chapter 4- Setting Up the QSX System
Connect the QSX System
Connect the QSX System, by following these steps (for more information and a graphical
depiction of these steps, consult your QSX Quick Start Guide.
1. Connect the following cables:
• LAN Cable. Connect the LAN cable from the back of the QSX unit to an
active LAN port in the area where the QSX will reside.
• Power Cable. Connect the Power Cable from the back of the QSX unit to
an available power outlet.
• VGA Cables.
For the QSX 400, connect the Content Controller to the VGA-In port
on the back of the QSX unit, and then connect the VGA cable to
the Content Controller itself.
For the QSX 300, connect the VGA Cable directly into VGA-In port
on the back of the QSX unit.
If you plan to display content on a projector or second computer monitor in the
area where the QSX will reside, you will need an additional VGA cable that
connects from the VGA-Out port on the back of the QSX unit to the
display equipment. Note that this VGA Cable is not included with the QSX
system.
Note: The only way to display the Info screen is to use a second display (e.g.-
second monitor, projector, etc.)
