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.

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 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.
