JetNet 3500 Series provides plug-n-play Super Ring function. When JetNet 3500s are not
connected in a Super Ring topology, these 5/8 ports serve as Ethernet ports. But, when you set
up a group of JetNet 3500s in a Super Ring topology by using port 4/5 of JetNet 3505 or port 7/8
of JetNet 3508, the JetNet 3500s will auto-detect the Super Ring setup. You don’t have to do
anything to enable or disable Super Ring function. One of the segments in the Super Ring
topology will be considered as the backup path. Normally, this backup path is blocked. But when
network disconnection occurs, the blocked backup path will be activated to restore the network
connection within less than 300 ms.
In a Super Ring topology, you need to set one of the JetNet 3500s to be the
Ring Master
. To do
so, set the DIP Switch located on the front panel of the JetNet 3500 that has
R.M.
written next to
it to
ON
position (See more details in
DIP Switch
section). Ring Master will be responsible for
negotiating and placing commands to other switches in the Super Ring topology. If there are
more than 2 switches that are set to be the Ring Master, JetNet 3500 will automatically select the
one that has the smallest MAC address range to be the Ring Master.
Installation and Testing
The following figure illustrates a typical application of JetNet 3500 Series Industrial 5-port/8-port
Entry-Level Ethernet Rail Switch.
1. Take your JetNet Industrial 5/8-port Unmanaged Redundant Rail Switch out of the package
box.
2. Check if the DIN-Rail clip is attached to the JetNet. If the DIN-Rail clip is not attached to the
JetNet, refer to DIN-Rail Mounting section for DIN-Rail installation. If you want to wall-mount
the JetNet, refer to
Wall-Mounting Installation
section.
3. To place the JetNet on the DIN-Rail track or wall, refer to the
Wall-Mounting Installation
section.
4. Pull the terminal block off the JetNet and wire the power lines. Refer to the
Wiring the
Power Inputs
section for how to wire the power inputs.
