NETWORKING
SNAP PAC Brains User’s Guide
16
Never connect SNAP PAC brains in a loop or ring
. For example, do not connect both ends of the
chain to the same switch, nor to different switches on the same network. As a rule, do not connect
the second Ethernet interface on the last brain in the chain to any other device.
NOTE: There is one exception to this rule: you can connect the network in a loop if at least one switch in the
loop supports STP/RSTP (Spanning Tree Protocol/Rapid Spanning Tree Protocol) and has that feature
enabled.
Connection from network,
controller, or PC to brain
Daisy-chain connections
Leave the 2nd
interface on the last
brain unconnected.
NOTE: Connection
from a PC does not
require a crossover
cable.
