SISTF10xx-130-LR(T)

Installation

DIN-Rail Mount

The SISTF10xx-130-LR(T) Ethernet switch includes an aluminum DIN-Rail mounting plate attached to the device’s back panel. To mount the SISTF10xx-

130-LR(T) onto a DIN-Rail:

1.Insert the top of the DIN-Rail into the upper slot of the mounting plate. The stiff metal spring should be positioned behind the DIN-Rail.

2.Push down and rotate the device to snap it into place on the DIN-Rail as shown.

NOTE: This device is intended to be grounded to a well-grounded mounting surface such as a metal plate. Install the grounding wire prior to connecting any other device.

Ground the SISTF10xx-130-LR(T)

Grounding the device helps limit the effects of noise due to electromagnetic interference (EMI). The grounding screw is located on the top panel next to the terminal block.

Installation -- Continued

The SISTF10xx-130-LR(T) is a plug-and-play unmanaged Ethernet switch with Redundant Ring technology for better network reliability and faster recovery time. The recovery time is less that 300 ms compared to 3 to 5 minutes for commercial switches. Also, when one segment of the network gets disconnected, the Redundant Ring automatically re-establishes network connectivity.

Master Device

The Redundant Ring technology identifies one switch as the Ring Master of the network, and then automatically blocks packets from traveling through any of the network’s redundant loops. To designate one of the SISTF10xx- 130-LR(T) devices to be the network’s Ring Master, set switch 6 on that device to “ON”.

If two or more devices are set to be the Ring Master, those devices with their switch 6 set to “ON” auto-negotiate to determine which one is the Ring Master. Also, if none of the devices are set to be the Ring Master, the Redundant Ring technology chooses the device that has the smallest MAC address range to be the Ring Master.

The actual topology of the Redundant Ring (i.e., which segment is blocked) is

determined by the number of	100BASE-FX		Switch

grounding screw

terminal block

To ground the SISTF10xx-130-LR(T):

1.Connect one end of the grounding wire (not included) to the grounding screw by looping one end of the grounding wire under the star washer.

2.Tighten the grounding screw with a phillips-head screwdriver.

3.Connect the other end of the grounding wire to earth ground.

If there is an even number of devices in the ring, the backup segment is one of the two segments connected to the unit directly opposite the Ring Master:
