Chaining BitStorm 2600s
Up to eight BitStorm 2600s can be chained together to use a single uplink. The
same port (eth2 or eth3) used as the uplink for one unit must be used as the
downlink for the next. For example, in this illustration:
The top unit has Port 3 (eth3) defined as its uplink and is connected to Port 3
of the next unit in the chain using a straight-through 8-position modular cable.
The middle unit has Port 2 (eth2) defined as its uplink and is connected to
Port 2 of the next unit.
The bottom unit has Port 3 (eth3) defined as its uplink, which is the uplink for
the stack. That unit is using the fiber interface.
Copper cables connecting:
Port 2 to Port 2 must be at least 3 feet (0.9 m) long
Port 3 to Port 3 must be at least 6 feet (1.8 m) long
Shorter cables may cause data errors.
