Removing a Module
1.
If the modules are held in place with screws,
remove them.
2.
Holding the SNAP module tool (provided) as
shown in the illustration at right, insert it into
the notch at the base of the module.
3.
Squeeze the module tool against the module
to open the release latch, and pull straight up
on the module to remove it.
Installing the Controller
CAUTION:
Make sure you are using the correct rack
for your controller. All SNAP PAC R-series controllers
except the SNAP-PAC-R1-B use a SNAP PAC rack (or a legacy SNAP M-series rack). SNAP-PAC-R1-B uses a B-series rack
(with a B in the part number; this controller does not work on a SNAP-D64RS rack). Using the wrong rack will severely
damage the controller.
1.
Remove the controller from its packaging.
2.
Turn off power to the rack assembly.
3.
Align the controller connector with the mating
connector on the mounting rack.
4.
Seat the controller onto the connector and use
the hold-down screw to secure the controller in
position. Torque: 8 lbf-in (0.9 N-m). Do not
overtighten.
5.
Using Category 5 or superior solid unshielded
twisted-pair cable, connect the controller in one
of the following ways:
–
(Recommended for initial configuration)
Connect to a PC directly, using an Ethernet
crossover cable.
NOTE: Wired+Wireless models must be configured using a wired network before they can be used on a wireless
network.
NOTE: If you use a crossover cable, make sure to assign a fixed IP address to the network card (NIC) on your
computer. Otherwise, if your network card is configured to get its IP address via DHCP, when you unplug the
computer from the network, the computer will no longer have an IP address. When you are finished using the
crossover cable, you can change the setting back to DHCP.
–
Connect to a standard 10BASE-T or 100BASE-TX Ethernet network that has a PC on the same subnet
as the controller and does NOT have a Dynamic Host Configuration Protocol (DHCP) server.
NOTE: When connecting the controller to a managed switch, make sure the managed switch's port
configuration is set to Auto for the Duplex setting and Auto for the Speed setting.
Maximum cable or segment length is 100 meters; minimum cable length is one meter. For more
information on cables, see
