Task 1: Verify the Selected Sitebbbbbbbbbbbbbbb
NOTE:
Defining the system requirements and ensuring that the site meets these
requirements are the responsibility of the Project Manager and the
customer and must be completed before you install the DEFINITY LAN
Gateway system. However, the guidelines are listed here so that you are
aware of these requirements.
Verify that the site selected for the DEFINITY switch and the DEFINITY LAN
Gateway system provides the following:
A DEFINITY Generic 3V4 switch, or DEFINITY Generic 3V4 software that
incorporates a field maintenance upgrade for G3V2/V3.
For a DEFINITY LAN Gateway system being installed in an existing
switch, five contiguous slots in a switch carrier to house the DEFINITY
LAN Gateway system (slots 16 to 20 in Figure 2-1 that follows).  (See
Appendix A for carrier worksheets.)

Humidity range of 20% to 80%, noncondensing. In addition, make sure the
site is secure and provides protection from excessive sunlight, heat, cold,
chemicals, static electricity, magnetic fields, vibration, and grime.
NOTE:
ASAI must be enabled on the DEFINITY Customer Options form for the
system to be fully operational.
Task 2: Gather Required Toolsbbbbbbbbbbbbbbb
To install a DEFINITY LAN Gateway system, you need the following tools:
Narrow width, flat-blade screwdriver
1/4-inch nut driver (recommended)
Antistatic grounded wrist strap
Punch-down tool
Task 3: Review Safety Considerationsbbbbbbbbbbbbbbb
!WARNING:
Electronic equipment can be damaged by electrostatic discharge. Do not
touch any electronic component unless you are properly grounded.
!DANGER:
Do not touch the switch backplane while installing the DEFINITY LAN
Gateway system. The backplane contains dangerous voltages and current.
To prevent damage to the equipment and yourself, adhere to the following:
Make sure you are familiar with the procedures necessary to prevent
electrostatic damage to the equipment.
Properly ground a wrist strap.
Place the grounded wrist strap on your bare wrist. (The wrist strap must
contact your bare skin directly  Ð do not wear it over your clothes.)
Do not remove the system assembly from the polyethylene bag until:
Ð Your wrist strap is on your wrist and properly grounded.
Ð You have made room in the switch carrier and you are ready to
insert the system assembly in the carrier.
If you need to work on the system assembly  Ð that is, disassemble it  Ð
place the assembly on a grounded antistatic work mat.

Task 4:  Verify Components and
Connectivity
bbbbbbbbbbbbbbb
Study Figure 2-2 that follows to gain a general understanding of how the system
assembly is to be connected.  Some customer-furnished LAN equipment is
included within the dotted lines in this figure.  Helpful definitions for this
equipment are as follows.
Balun (balanced/unbalanced) Ð An impedance matching transformer.
Baluns are small, passive devices that convert the impedance of coaxial
cable so that its signal can run on twisted-pair wiring. They are used often
so that IBM 3270-type terminals, which traditionally require coaxial cable
connection to their host computer, can run off twisted-pair.  Baluns work
for some types of protocols and not for others.  There is often some
performance degradation with baluns, and the signal cannot run as far on
twisted wire as it can on coaxial cable.
10BaseT Hub Ð An Ethernet LAN that works on twisted pair wiring which
looks and feels like telephone cabling.  10BaseT Ethernet LANs work on
home runs in which the wire from each workstation snakes directly to the
10BaseT hub (like the wiring of a phone system).  The advantages are
twofold Ð first, if one machine crashes, it doesnt bring down the whole
network, and second, 10BaseT hubs often come with sophisicated
management software.

Hardware Installationbbbbbbbb
This section describes the tasks needed to install the DEFINITY LAN Gateway
system hardware and peripheral hardware.
The DEFINITY LAN Gateway system installation tasks are the same for all
switch types. These tasks include:
Task 5:         Install the DEFINITY LAN Gateway system assembly
Task 6:         Connect the Alarm Board cables
Task 7:         Install the terminal (optional)
Task 8:         Connect the Maintenance Modem
Task 9:         Finalize and test the hardware
Before beginning these tasks, refer to the following worksheets:
Appendix A, PBX Carrier Configuration Worksheets
A-1, Port Slot Assignments (Before Carrier Rearrangement)
A-2, Port Slot Assignments (For Carrier Rearrangement)
A-3, Port Slot Locations for the DEFINITY LAN Gateway System
Assembly
Appendix B, Supported Terminals and Modems/Option Settings
B-1, Terminals/Modems
Task 5: Install the DEFINITY LAN Gateway
System Assembly
bbbbbbbbbbbbbbb
This task is required for all installation scenarios.
!WARNING:
To prevent damage to the DEFINITY LAN Gateway system assembly,
make sure that you (or the factory, for new switches) have connected the
system assembly adapter cables to the port connectors on the back of the
switch (as described in Step 3) before you insert the system assembly in
the switch carrier.
You can install the system assembly in the switch when the switch is
powered on or off. When the assembly is inserted in the slots of the switch
carrier, it will automatically power up, run diagnostics, and boot. To avoid a
disk crash, never remove the assembly without first completing the
shutdown procedure to shut down the DEFINITY LAN Gateway system
(and allowing the disk to completely spin down).
Issue 1  January 1996   2-7 
						

							Installationbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
For the same reason, do not cycle the power on the switch (for example,
during switch acceptance tests) once the system assembly is inserted
unless you have first shut down the DEFINITY LAN Gateway system. Refer
to the maintenance screens in Chapter 3 for the shutdown procedure.
Slot and Carrier Restrictions
If rearrangement of circuit packs in the PBX is required to accommodate the
system assembly, rearrange the packs as indicated on Worksheet A-2, Port Slot
Assignments, before proceeding.
There is a maximum of one system assembly per Single Carrier Cabinet (SCC)
or MultiCarrier Cabinet (MCC). This assembly occupies five slots and should be
placed to the far right in the carrier.  For thermal reasons, the system assembly
should not be placed in MultiCarrier Cabinet C carrier position (top carrier
position).
See Appendix A, ``PBX Carrier Configuration Worksheets, for detailed
information on the rearrangement of circuit packs and slot restrictions.
DEFINITY LAN Gateway System Slots
The system assembly requires five contiguous port slots in the switch carrier.  In
this description, the five slots are referred to as the first through the fifth slot, with
the understanding that they can be any five contiguous port slots.  It is
recommended that it be installed as far to the right as possible.
The slots are numbered from left to right on the front panel of the switch cabinet,
and from right to left on the rear panel as shown in Figure 2-3, Connecting the
Adapter Cables, Rear-Panel View.  The five port slots are occupied by the
DEFINITY LAN Gateway system assembly as follows:
The first and second slots are covered by the DEFINITY LAN Gateway
disk and removable media and are not connected to the switch backplane
or amphenol connectors.
The third slot is connected to the Alarm Board (ALB).
The fourth slot is connected to the Multi-Function Board.
The fifth slot remains vacant to provide added clearance and cooling for
certain components on the Multi-Function Board.

Installation Steps
Using Worksheet A-3, Port Slot Locations for the DEFINITY LAN Gateway
System Assembly, follow the steps below to install the system assembly.
1. Remove any existing cables from the third and fourth slots of the five
contiguous slots reserved for the DEFINITY LAN Gateway system.  For
example, if you are to install the DEFINITY LAN Gateway system in slots
7 through 11 of carrier A in the switch, remove the I/O cables from slots 8
and 9.  (These are the two slots that provide connectivity to the DEFINITY
LAN Gateway system circuit packs.)
2. Referring back to Figure 2-3 and to Steps 2a and 2b that follow, connect
the DEFINITY LAN Gateway system assembly adapter cables to the port
connectors on the back of the switch.
Issue 1  January 1996

							Installationbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
NOTE:
You must connect these adapter cables directly to the port
connectors on the switch. If you install another cable between the
switch and the cables, the DEFINITY LAN Gateway system will not
operate correctly (either now or in the future).
a. Attach the male D-type amphenol connector on the Alarm Board
(ALB) cable (the one with two amphenol connectors, one RJ45
LAN connector, and one 25-pin RS-232 connector) to the ALB
(TN2170), the third slot of the five DEFINITY LAN Gateway system
slots.
b. Attach the male D-type amphenol connector on the Multi-Function
Board (MFB) Y-cable (the one with one amphenol and two RS-232
connectors) to the MFB (TN2208), the fourth slot of the five
DEFINITY LAN Gateway system slots.
NOTE:
If you are installing the DEFINITY LAN Gateway system in a
DC-powered switch, perform the following steps to install the 116A
isolating data interface.  Otherwise, skip to Step 4.
3. Install the 116A isolating data interface.
a. Attach the male end of a null modem (supplied with the DEFINITY
LAN Gateway system PEC) to the RS-232C connector on both
PORT A and PORT B on the MFB Y-cable.  Attach the male
connector of the 116A to the other end of the null modem.
b. Attach the male end of another null modem to the RS-232
connector labeled RESERVED on the ALB Y-cable.  Attach the
male connector of the second 116A to the other end of the null
modem.
4. Insert the system assembly (see Figure 2-4, DEFINITY LAN Gateway
System Assembly) into the switch cabinet as follows:
Holding the system assembly by the outside edges of the faceplate, line
up the Alarm Board and the Multi-Function Board with the bottom guides
of the third and fourth slots, respectively, of the five reserved port slots in
the switch carrier.
