CONTEMPORARY CONTROLS EISW8-100T Plug and Play Switching Hub for

Automation Systems

Installation Guide

The EISW8-100T 8-port switching hub is designed for networked automation applications. Like all Ethernet switches from Contemporary Controls, it features non-blocking (full wire-speed) operation. It divides an Ethernet network into eight collision domains—“bridging” data links to create larger network diameters than possible with repeating hubs. Each port automatically negotiates its data rate to either 10 Mbps or 100 Mbps—controlling data flow with the PAUSE function in full-duplex links or with the backpressure method in half-duplex links. The switch provides preamble regeneration with symmetry and amplitude compensation, retiming signals to eliminate jitter. Digital pre- emphasis compensates for inherent signal strength roll-off. Link integrity is monitored, verifying that a working adapter or hub is on the distant end of a segment. Port assignments are learned by reading Ethernet frames and logging the source addresses to a table. Throughput is improved by restricting traffic to those ports party to a data exchange while other data is simultaneously exchanged on other ports. Store-and-forward operation is implemented, and broadcast, multicast, or unicast transmissions are received by all ports. The EISW8-100T has eight Auto-MDIX ports for attaching local devices. Each port has one LED that glows with an established link and flashes with activity. The unit features dual power inputs with wide-ranging voltages (12-48V DC or 24V AC). For power redundancy, two DC supplies can be used. A normally open (NO) fault relay contact held closed, opens upon a P1 or P2 power failure. This contact is rated up to 24V DC at 1A. A wide operating temperature range of –40°C to +75°C makes the EISW8 suitable for outdoor applications.

Power Sourcing Options

1. Single Source Powering PWR1 with AC PWR1 with DC Possible grounded secondary
2. Redundant Powering PWR1 with DCPWR2 with DC Power supplies must be isolated from each other

• Power Considerations
  The EISW can be powered from either a single source of AC or DC. Dual source powering is possible with two DC supplies isolated from one another. The recommended size for solid power conductors is 16–22 AWG; for stranded conductors, use 16–18 AWG. Input connections are reverse polarity protected. The earthing screw terminal on the switch must be grounded if there is no other option for grounding the case.

• Network Connections
  The switch employs Auto-MDIX technology so that either straight-through or crossover cables can be used to connect to network interface adapters or to another hub.

• LED Indicators
  The “P1” LED glows green to indicate Power Input 1 (PWR1) has power, and the “P2” LED glows green to indicate Power Input 2 (PWR2) has power. Each Ethernet port has an LNK/ACT LED that glows solid green to indicate an established 10 or 100 Mbps link and flashes green to indicate that network traffic is occurring over that port.
