Port card
There is only one port card type available for S-Class. The 482 port card is equipped with a standard
female amphenol connector for easy wiring to a standard 66 or 110 block. The S-Class 482 port card
cannot be used on any other ESI phone system.
Warning: 482 port cards for IVX 42s (Generation I) are not compatible with IVX 56s (Generation II); use only
port card boards marked 5010-0579 with S-Class main boards marked 5010-0578 or 5010-0590.
The 482 port card provides circuits to connect up to four loop-start CO lines, eight Digital Feature Phones,
and two analog station ports. The CO line ports support standard CO and Centrex loop-start lines;
ground-start CO lines are not supported. The analog ports provide a standard 24-volt, two-wire connection
to fax machines, analog phones, and modems. Only one analog device can be connected to each
analog station port. This card uses ten station ports and four CO ports when installed.
Notes: The S-Class main board comes in a four-line, eight-digital station, two-analog port configuration.
You can add either two1or three2482 port cards on an S-Class system. Therefore, the system can
have the following configurations.
— 4 8 2: Base Cabinet (main board only)
— 8 16 4: Base Cabinet with one 482 port card.

IVX S-Class Installation Manual Hardware overview/installation
B.8
Expansion Cabinet installation
The Expansion Cabinet provides for the expansion of each Base Cabinet with one additional port card
(in addition to the one additional port card slot available on the Base Cabinet). The Expansion Cabinet
houses up to two port cards connected via ribbon cables through the opening in the back of the
Expansion Cabinet to the Base Cabinet.
IVX S-Class Generation II houses up to three port cards, as shown.
To install an Expansion Cabinet:
1. Wear a grounding strap and avoid unnecessary movement while
handling the circuit boards.
2. Unplug the power to the IVX S-Class system.
3. Remove the Base Cabinet lid by pressing the release tab at the top of
the Cabinetand rock back the lid from the bottom of the Cabinet.
4. Install the Expansion Cabinet on the front of the Base Cabinet in
place of the Base Cabinet's lid.
5. Lock the Expansion Cabinet to the Base Cabinet by snapping the top
in place and reinstalling the retaining screw.
6. Connect the grounding strap from the Expansion Cabinet's grounding
lug (located on the bottom of the cabinet) to the Base Cabinet's
grounding lug. Follow the grounding procedures as described earlier
for grounding the Base Cabinet.
7. Through the large opening in the back of the Expansion Cabinet,
connect the ribbon cable as follows:
• On IVX S-Class Generation I — Connect J1 on the port card to J2
on the card directly below.
• On IVX S-Class Generation II — Connect J5 on the port card to
the J6 on the card directly below.
8. Re-install the original lid from the Base Cabinet on the face of the
Expansion Cabinet.

IVX S-Class Installation Manual Hardware overview/installation
B.9
Port card installation
Adding or replacing port cards will require the system to be taken out
of service. Wear a grounding strap and avoid unnecessary movement
while handling the circuit boards.
1. Unplug the power supply to IVX.
2. There are two card slots on each cabinet (Base Cabinetand
Expansion Cabinet). Each card is ribbon-cabled to the port card
directly below it.
Note: The firstAmphenol connector (Port Card 1 slot) is
occupied by the main board, which comes in a four-line,
eight-digital station, two-analog portconfiguration.
3. Using the ribbon cable that shipped with the port card, connect
the port card in the Base Cabinet to the main board as follows:
• On IVX S-Class Generation I — Connect J1 in the Base Cabinet to J1 on the main board.
• On IVX S-Class Generation II — Connect J5 in the Base Cabinet to J5 on the main board.
4. Secure the port card to the standoffs with the screws that shipped with the port card.
5. To remove the port card, reverse steps 1–4.
Memory Module
Note: The Memory Module has a proprietary formatting scheme —do not attempt to install a non-ESI
hard drive. Contact ESI for a replacement Memory Module, if needed.
Adding or replacing the Memory Module will require that the system be powered down.
Replacingthe Memory Module erases all its configuration data and custom recordings.
(Prompts stay intact, however.)
LED functions
The unit's various LEDs are designed to provide visual feedback as follows:
Power LED
The Power LED is located on the top-right side of the cabinet and is illuminated when power is being
applied to the system.This LED blinks periodically to indicate that the main processor is operational.
Port LEDs
The Port LEDs are located above their respective amphenol connectors on the right side of the cabinet.
Each LED is illuminated when any port on its associated port card is in use.
Note: Disconnecting an amphenol connector when its respective LED is lit will cause any of its ports that are
in use to be disconnected.
Upon power-up, approximately one minute is required for the system to configure. During power-up, the
Power/Status and Port LEDs are either lit solid,off, or rapidly blinking — indicating the progress of the boot-
up process.After power-up is complete, Power/Status blinks once per second.
Memory Transfer LED
This LED is located inside the cabinet in the center of the main board. It serves as a diagnostic aid by
flashing as data is transferred to and from the Memory Module.

IVX S-Class Installation Manual Hardware overview/installation
B.10
Grounding instructions
System grounding (supplemental ground) is as follows:
• The conductor wires can be no smaller than the ungrounded branch-circuit supply conductors
(usually 16-gauge or larger).
• Acceptable wire: bare or covered with green (or green-and-yellow-striped) jacket.
• Conductors (and power receptacles) shall connect to earth ground at the service equipment (usually
a cold water pipe or copper ground rod).
• The supplemental ground must: be used regardless of power cord ground, be connected to the
ground lug on the bottom of the IVX cabinet, and retain ground connection when IVX power supply
module is unplugged.
Note: IVX S-Class system lines are protected against a 10 KV surge only if the earth ground procedures
described above are followed.
Power
The system cabinet requires a 120 VAC outlet (if possible, a dedicated outlet). Use only the Class-2
power supply module provided. A clean, isolated power source in conjunction with a UPS (see “UPS,”
below) is STRONGLY recommended. The system draws a maximum of 50 watts.
If AC power is interrupted, the system will drop all connections. When power is restored, the system
will resume normal operation in approximately one minute, having retained its full programming and
clock setting.
UPS
For system protection and to maintain uninterrupted operation, an uninterruptible power supply (UPS, or
“battery back-up”) is STRONGLY recommended. A UPS rated for 200 VA will provide approximately
two hours of uninterrupted service for an IVX S-Class system. Therefore, ESI recommends that only
true sine wave output UPSs provide backup power to our phone systems and equipment.
Note: The remaining information under “UPS” comes from Technical Update #216.
Most people have heard about UPSs, but seem to think that there is just one kind of device that goes by
that name. In fact, there are several different major designs in use by today’s major UPS manufacturers.
These makers share much of the blame for confusing UPSs’ end users by, far too often, lumping
different designs under the “UPS” name.
UPSs can first be broken down into system types:
• Stand-by — A very simple design that affects power only when either a lag/brownout occurs below,
or a spike/surge occurs above, a certain threshold. When either occurs, the unit trips — i.e., goes into
battery mode. This "cleans" the voltage and helps to keep any load safe. Industry average "trip" times
are 2–8 ms. No other filtration ofAC power is performed.
• Line interactive — Constantly monitors inbound voltages, and uses special circuitry to boost low
voltages and clamp high voltages without having to use the batteries. Indeed, the batteries are used
only if the input voltage drops below acceptable levels (typically about 12% below normal), goes out
completely or rises to dangerous levels (typically about 14% above normal) at which components will
be damaged if line voltage is not removed. Industry average transfer time is 1–3 ms. (If voltage stays
within its normal window, this unit continues to pass voltage, unaltered, from the wall.)
• On-line (or full on-line) — Constantly filters the power and performs a function known as double
conversion (AC to DC to AC). This assures that the load — in this case, phone equipment — will
receive not only uninterrupted, true sine wave output butalso the cleanest, steadiest power possible

throughout any foreseeable power disruptions or voltage irregularities. According to industry specs, it
is not unusual for these types of units to be able to regulate utility power, even when it drops to 27%
below or rises to 33% above normal, all without using their batteries.
From this point, UPSs can be further broken down by inverter types, which determine output. These are:
• Square wave.
• Modified sine wave (or quasi sine wave).
• Sine wave.
Most devices with wall-mounted chargers, such as cordless drills or screwdrivers, can behave erratically
— sometimes not allowing the charge circuit to engage at all — when operating with modified sine or
square wave inverters. Small wall-based transformer-style power supplies, similar to those ESI phone
systems use, can experience overheating problems with modified sine or square wave outputs, which
occur while some UPSs are operating in battery mode.This overheating could eventually cause
damage to the power supplies; and, in time, the damage could cause a spike through the phone system
— seriously damaging some of the static-sensitive components inside the casing.
While the true sine wave UPS output power curve smoothly increases to its peak, then smoothly
decreases (allowing connected loads and equipment to operate the same as they would from utility
supplied wall power), the modified sine wave and square wave UPS output power curve will shoot
straight up, level off at peak voltage and then drop straight down. Additionally troublesome is that the
modified sine wave sits at zero voltage for a short period during the transition to or from batteries —
which is the main difference between it and the square wave output of some UPS. Please note that this
short interval during which the modified sine wave UPS sits at zero voltage can directly affect the
transfer time of the UPS and could, theoretically, be enough to cause the phone equipment to reset or
even “freeze.”
Though it is hard to predict exactly when different ESI systems will have problems with modified sine
wave or square waveform UPSs (meaning during a power failure event or the recovery from one), it’s
fair to assume that a problem will eventually arise from the use of such UPSs.
MOH port
The MOH (messages-, or music-, on-hold) connector on the upper right side of the cabinet is a standard
1/8″monophonic mini-jack, used for loading custom MOH recordings or for playing live music-on-hold
from an external source such as a radio or CD player.

Serial ports for maintenance and SMDR
The Maintenance/SMDR port is a standard DB9 serial connector located on the side of the cabinet.
For printer-to-computer connection, use a standard shielded serial cable, DB9-to-DB9, male-to-female.
Note: The maximum distance from the cabinet is 100 ft.
The output from the Maintenance/SMDR port is, 8 data bits, 1 stop bit, and no parity. The pinout is:
Data Transmit Pin 2
Receive Pin 3
Ground Pin 5
Range: Programmable for 300, 1,200, 2,400, 4,800, 9,600, 19.2K, 38.4K, or (Generation II only)
115K bps. Default: 38.4K.
Maintenance
Connect a PC (such as a laptop) to the port to perform on-line programming via Esi-Access.
SMDR
The IVX S-Class system continuously outputs real-time SMDR call records to the DB9 serial port.
Note: The system will buffer up to 1000 SMDR records (80 KB) in non-volatile memory (CompactFlash) when
the maintenance port is in use for programming or uploading. When the buffer reaches capacity, the
oldest records are discarded.
External paging device connection
A dry contact overhead-paging device can be connected to the system through the main board's 66
block connector. The overhead paging port is fixed (located on the main board) as extension 199 for
programming purposes and user access.
Audio connection
The audio pair is connected to the 66 block at terminal 33 and 34. The pair’s impedance is 600 ohms.
Dry contact control
The manner in which the dry contact pair is punched down on the 66 block sets the pair as normally
open (sending a page to the port will close the contacts) or normally closed (sending a page to the port
will open the contacts). Connect the dry contact pair of the device either (a.) to Terminals 35 and 36 to
provide normally open operation; or (b.) Terminals 36 and 38 to provide normally closed operation.
The port can be used with zone paging units.
Note: The port doesn’t support talk-back paging (which requires a CO port), nordoes it support CO ring
through the port.

Amphenol cable connections
Connect a standard 66 Block using a male 50-pin amphenol cable to the portcard’s female connector
located on the bottom-right side of the cabinet. The connector closest to the wall is the first port card,
(which is the main board on the S-Class).
CO line connection
Local loop
The IVX S-Class system's advanced CO line circuitry provides for open loop detection and the system’s
built-in Caller ID interface.
Note: Observe correct order of connection to preserve proper rotary hunting of the CO lines.
Station connection
The first eight pairs on the amphenol are station ports.
All stations are connected using a single pair. Each port position is pre-numbered and fixed as indicated
in the 66 Block Wiring Diagram.
ESI recommends using a minimum of 20 feet of Cat-3 or Cat-5 cabling, and the provided ESI line cord,
for each ESI Digital Feature Phone or ESI Cordless Handset Base Station.
Note: The station runs can be up to 1,000 ft.
Digital stations
The digital station wiring is not polarity-sensitive. Only one phone can be connected per digital port.
Important: Each ESI Presence Management RFID Reader uses one digital station. IVX 56s (IVX S-Class
Generation II) limits the number of possible RFID Readers to two perport card.
Analog ports
The analog ports do not require that tip-and-ring polarity be observed. The analog ports can be used for
2500 type sets or for devices such as fax machines, cordless phones, etc., that can be connected via a
normal tip-and-ring pair. Each analog port will support only a single analog device.
Station Numbering Plan
Each port card has 10 station interfaces.
Generation II Generation I
