Getting Started 2-3
Installing Plug-
Ins
Make sure the power is turned off before installing or
removing plug-ins.
Inserting or removing plug-ins with power on
may cause damage to the 1256 and the plug-ins.
Figure 2-2, Inserting a Plug-In
shows the proper way to install an
Adapt-a-Switch plug-in into the 1256 chassis. When inserting the
plug-in, engage the edges with the card guides of the 1256.
Carefully slide the plug-in into the chassis until it stops, then push
it firmly to engage its rear connectors with the 1256 backplane.
When the plug-in is fully seated, its panel is flush with the rear
panel of the 1256 chassis.
Each plug-in has retainer screws at the ends of its front panel.
Carefully thread the retainer screws into the 1256 chassis and
tighten securely.

Numbering of
Plug-In Slots
The 1256 references each plug-in by the number of the chassis
slot into which it is installed. There are no configuration jumpers or
settings. Refer to
Figure 2-3, Numbering of Switch Plug-In
Slots
