Power Up and Reset
Power Up and Reset
Operators generally do not need to bother about startup — unless there is a power outage.
At power-up and at every reset a control panel’s ‘Panel Lock’ button is on and red. An operator
must turn the panel lock off before the panel can be used.At power-up, a remote panel “discovers”
the state of the routers in the network and illuminates its buttons to reflect the routes and levels that
were selected prior to power-up (reset). It can take up to 60 seconds to finish the discovery. The
operator can actually start using the panel before the discovery completes.
During System Construction
The system builder must be aware of several additional facts.
To power up a router or remote panel module, connect the 4-pin connector of the power supply to
PS1 or PS2. Then plug the power supply into an AC power outlet. If you have chosen to use two
power supplies for redundancy, connect one to PS1 and the other to PS2.
Routers at Power-Up
At power-up, a router loads stored program code into its internal FPGA and restores its previous
operational state. (Its “state” includes the name, crosspoint map, levels, and which of the outputs
are locked.)
At power-up, the router detects the presence or absence of a video reference signal.
(The AES routers switch immediately to synchronous mode if a video reference is present. Other-
wise they remain in asynchronous mode.)
Remote Panel Modules at Power-Up
At power-up, a remote panel module also loads stored program code into its internal FPGA and
restores its previous operational state. (Its “state” includes all the button definitions and its own
panel mode.)
Note If a router’s rotary switch is set to the 0 position, the router reverts to the factory
default state, not its previous state. Its entire state and all configuration data are
lost.
Note If a remote panel module’s rotary switch is set to the 0 position, the remote panel
module reverts to the factory default state, not its previous state. Its entire state
and all configuration data are lost.
The control panel mounted on a router or a remote panel module obscures the
rotary switch.
