Installation and Operation, cont'd

Operation

Apply power and the input signals. The video and audio
output connectors, including the Loop Thru Input 1 connector,
should output signals.

Input selection

There are two ways (if the switcher is in a stand-alone
configuration) or three ways (if the switcher is in a daisy chained
system) to select between input 1 and input 2. These methods
also work when daisy chaining to issue the "show me" signal to
the other switchers in the chain.
• Push the Show Me button on the VSW I AAP to select
input 1 on the connected VSW 2VGA A switcher.
• Toggle the front panel input select switch up (input 1) or
down (input 2).
• Use the rear panel contact closure capability.
Identifying the Board Revision and
Setting the VSW 2VGA A Jumpers
N If you plan to create a daisy chain configuration, you must
configure the switchers before installing them in a rack or
furniture and making connections.
Daisy chaining VSW 2VGA A switchers requires you to check
and/or set internal jumpers in the switcher. Daisy chaining also
requires you to check the revision level of the switcher and use
that information to check and/or set jumpers in the VSW I AAP
control panels.
1. If applicable, disconnect all power to the switcher and any
attached devices.
2. Remove the two screws on each side of the switcher
(figure 2-13). Remove the four connector nuts on the front
panel of the switcher. Lift the top cover off of the switcher.
