– Introduction
20 REASON SWITCHES-TM-EN-3
4 Available models
4.1 T1000
T1000 is a managed switch and supports both NTP, operating as NTP client, and PTP,
used for IED synchronization.
The modular conception of T1000 switch allows up to 12 Ethernet ports (6 sets of 2
interfaces) supporting copper Ethernet communication (10/100/1000 Mpbs) and
Fibre Optic links (100/1000 Mpbs). For optical interface, ST (100 Mbps) and LC
(100/1000 Mbps) are available. LC Fibre links support multimode or single mode fibre
optics, and ST Fibre links support only multimode fibre optics.
Communication interfaces can be replaced or changed in the field with the
equipment in the panel.
4.2 S2020
The S2020 is a fast control Ethernet switch designed for less critical applications in
industry and power systems, such as the connection of high level equipment in the
automation architecture.
S2020's conception allows up to 20 Fast Ethernet ports or up to 16 Fast Ethernet
ports plus 4 Gigabit ports. The ports are in a module, containing 4 ports each, which
support copper Ethernet communication or LC connector Optical Fiber links
(multimode or single mode optical fiber).
S2020 only supports NTP synchronization protocol (client operation). If PTP is
required, refer to T1000 or S2024G.
4.3 S2024G
The S2024G is a managed gigabit Ethernet switch designed for applications that
request an increased number of Ethernet ports and Gigabit connection to most of
the nodes. The S2024G allows up to 24 Gigabit Ethernet interfaces operating
simultaneously.
S2024G supports IEEE 1588 v2 protocol (PTP) used for IED synchronization. In
transparent mode (TC), all ports support PTP by using time correction performed in
software (operation in two-step mode). In Boundary Clock (BC) mode up to 2 ports
can be used as a synchronizing input, leaving the remaining ports to be programmed
as outputs. S2024G may also operate as a NTP client.
Copper Ethernet communication (10/100/1000 Mpbs) and LC connector Optical Fiber
links (100/1000 Mpbs) are available. Optical Fiber links support multimode or single
mode optical.
