Identifying installed modules and
viewing
closed channels
On power-up, the model numbers of installed switching modules are displayed briefly.
If a Model 7700, 7701, 7702, 7703, 7705, 7708, or 7709 switching module is removed
while the Model 2700 is on, the instrument will operate as if the module is installed. That
is, the Model 2700 will operate as if the pseudocard is installed.
NOTE If a Model 7706 or 7707 is removed while power is on, error +523 “Card
hardware error” will occur, and the module will be removed from the system.
NOTE In general, it is not recommended to install or remove switching modules with
the power on.
