EISC-100T

Ethernet Configurable Switching Hub

INSTALLATION GUIDE

Introduction

The EISC-100T (EISC) configurable switch in the CTRLink®family

provides capabilities beyond those of standard Plug and Play (PnP)

switches. Besides conventional features —auto-negotiation, 10/100

Mbps data rate, flow control, half- or full-duplex operation —the EISC

has advanced features such as VLAN, trunking, Quality of Service (QoS)

and a programmable fault relay that can be connected to a supervisory

system. Individual port parameters can be configured via a console port

attached to a Windows®-based workstation. Port status can also be

monitored through the console port using the Modbus protocol, making it

easy to interface the EISC with supervisory control equipment. These

features make the EISC one of the most versatile of Industrial Ethernet

switches available.

Configuration is accomplished via a console port connected to a

Windows-based configuration program included with the product.

Modbus protocol and register information is also provided so the switch

can be configured or monitored by a Modbus master device. Each port

parameter (data rate, duplex and flow control) can be pre-set via the

console port or set automatically via auto-negotiation. And a unique feature

displays the status (integrity) of the cable attached to any each port.

Each port automatically optimizes its data rate to 10 Mbps or 100 Mbps

—but data rate and duplex settings can be specified, if desired.

Each port negotiates flow control, but control can be disabled for

individual ports. The PAUSE function is supported for full-duplex links.

The backpressure scheme is used for half-duplex segments.

The EISC can be powered from wide-range, low-voltage

AC or DC sources and has provisions for either DIN-rail

or panel mounting.

Installation

Mounting

The EISC is designed for mounting in an industrial enclosure or wiring

closet using either set of the provided mounting hardware listed below:

TS-35 DIN Rail Mounting

Panel Mounting

DIN rail clip

Panel mounting bracket

4-40 screws, pan-head (2)

4-40 screws, flat-head (4)

For quick snap-mounting onto TS-35 mm DIN rail, a DIN rail clip is

pre-attached to the back of the enclosure with two #4-40 pan-head

screws. If the clip is removed, the unit can be panel-mounted by

extending the top and bottom brackets which are shipped in retracted

position. The extended brackets can then anchor the unit to a wall or

other flat surface with two #8 pan-head screws (not provided). The left

illustration of Figure 1 shows a rear view of the unit with brackets in

retracted position. The right illustration of Figure 1 shows the brackets

extended and secured to the unit enclosure using the same screws that

were used in the retracted position.

Powering

The EISC requires low-voltage power —AC or DC —via a removable

keyed four-pin connector which accepts 16–18 AWG conductors.

Consult the specifications for power requirements. Power options are

explained below.

NOTE: This device is intended for use with Class 2 circuits.

DC Powered

The EISC accepts a voltage range of 10–36 VDC and draws a maximum

current value commensurate with 12-watt power consumption. Power

conductors should be sized accordingly. Ground is directly connected to

zero volts and the equipment chassis is isolated from zero volts. The DC

voltage input connections are reverse-polarity protected.

Figure 2 —DC Powered

Redundant DC Powered

Redundant diode-isolated DC power input terminals are provided so that

the user can connect redundant power to the unit for operating despite the

loss of primary power. Both sources must provide 12 watts of power.

Figure 3 —Redundant DC Powered

TD021000-0IF

AC Powered

The EISC can be powered by an AC voltage in the range of 8–24 V

capable of delivering 12 VA of apparent power. Two auxiliary power

supplies are available as accessory items: The AI-XFMR is for 120

VAC. The AI-XFMR-E is for use with 230 VAC.

Figure 4 —AC Powered

Figure 5 —AC Powered with Grounded Secondary

AC Powered with Battery Backup

The EISC can also operate in the AC mode with a user-provided backup

battery supplying power, if the AC source fails. The EISC does NOT

charge the battery, so separate provisions are required for charging.

Operation

Switching

The EISC uses an 8K-address look-up table augmented with 64 entries of

Content Addressable Memory. A hashing algorithm is used to update the table.

Addresses are aged in about 300 seconds. Runt packets (less than 64 bytes) and

oversize packets (greater than 1536 bytes) are discarded.

Data Storage

Data storage buffer for Ethernet packets consists of 156 k bytes of SSRAM.

Data Forwarding

An entire Ethernet packet must be received before forwarding occurs.

Flow Control

Each port automatically negotiates flow control for either half- or full-duplex

operation, if auto-negotiation is enabled. In full-duplex mode, the PAUSE

function is supported. In half-duplex mode, the backpressure method is used.

When flow control is disabled, the destination port of an incoming packet is

checked and, if found to be congested, the packet is discarded to avoid blocking

the packet stream.

Broadcast Storm Control

Using a storm-control counter, each port will pass 64 continuous broadcast

packets before dropping extra ones. The counter will reset every 800 ms or after

receiving a packet whose Device ID is other than ff ff ff ff ff ff.

LED Indicators

P(green)

Power. Glows when power is supplied to the EISC.

(Numbered LEDs)

(green/yellow)

Link/Activity. Each port has an LED that glows if a link

exists: green for 100 Mbps operation or yellow for 10

Mbps operation. It flashes as data transfer occurs.

S(green)

Fault Relay Status. This LED functions in accordance with

its configuration setting. See the User Manual for details.

Ports

All ports are wired MDIX —allowing DTE equipment to connect via straight-

through cables —except that Port 16X is wired MDI to permit the cascading of

switches without the need of a crossover cable. Note that Port 16 and Port 16X

cannot be used simultaneously.

Advanced Operation

Advanced operation (requiring a null-modem cable) is explained in the User

Manual located on the provided CD-ROM.
