SNAP PAC Rack Adapter Installation
Introduction
SNAP PAC racks are designed to be used with SNAP PAC brains and
rack-mounted controllers. However, if you have an older I/O
processor that you need to use with a SNAP PAC rack, the SNAP-
RCK-B2M rack adapter makes it possible. The adapter can also be
used with SNAP M-series racks to accommodate processors that
would normally be used on a B-series rack.
The adapter works with the following part numbers:
Important Notes
Change in height: The adapter adds 0.595 inches (1.511 cm) to
the overall height of the unit.
Change in connector location: After installation of the adapter,
the brain or controller’s position will be reversed on the rack (as well
as being higher in relation to the rack), and letters on the lid will be
upside down. Make sure that cables can still reach the connectors
on the processor.
No new features: The adapter does not change the capabilities of
the brain. For example, four-channel digital modules still cannot be
used in module positions 8 and higher.
Installing the Adapter
Requirements
Part number SNAP-RCK-M2B includes the following pieces:
•Lockwasher
• 6-32 hex standoff
•Replacementbaseplate
•Adapter
You will also need a medium-sized Phillips screwdriver to install the
adapter.
Installation Steps
1. Remove all SNAP-RCK-B2M pieces from their packaging.
2. Turn off power to the rack.
3. If there is already a processor on the rack, disconnect any cables
connected to it. Loosen the screw holding the processor on the
rack and remove the processor. Set it aside.
4. Turn the replacement processor (brain or controller) upside
down. Remove the four small screws holding the black base-
plate on the processor, and remove the baseplate. Keep the
screws.
5. Hold the replacement baseplate so that its indentation is facing
away from the brain (see the following photo).
6. Align the brain’s hold-down screw with the center hole in the
replacement baseplate. Using the same four screws, attach the
replacement baseplate to the new processor.
7. On the rack, set the lock washer over the hole next to the pro-
cessor’s connector, and then screw the 6-32 hex standoff into
the hole. Tighten the standoff just to the position where two of
the hex points are parallel with the connector, as shown in the
photo on the following page.

8. Holding the rack adapter with its part number visible on the top
and the black connectors aligned underneath, set it in position on
the rack.
If it does not go on easily, make sure the hex nut’s points are prop-
erly aligned, parallel with the processor connector.
9. Align the processor’s blue connector with the mating connector
on the rack adapter, and make sure the indentation in the base-
plate aligns with the silver pins on the adapter.
The processor’s position is now reversed on the rack (that is, letters
on the processor’s lid are upside down).
10. Seat the processor onto the connector and use the hold-down
screw to secure the brain in position. Do not overtighten.
11. Replace cables and restore power to the rack.
If the replacement processor does not have an IP address, follow
instructions in the PAC Manager User’s Guide to assign it.
