Chapter 2 - Installation
2.1 INTRODUCTION
The majority of installed MD110 systems are one or two LIMs without a group switch.
This document is intended as course material for those who attend the installation course
for small MD110 systems, i.e. one or two LIMs without a group switch. It can also be used
as an installation manual after completed course.
Use the manual the first few times you install an MD110, then as a reference document as
you become familiar with the system. For a notebook, you can make a copy of the
Installation Checklist (Appendix 2), to ensure that you have not inadvertently skipped a
step in the installation process.
Keep in mind that additional sources are available to assist you. The ALEX CD-ROM for
ASB 501 04 offers about 50 binders worth of information that actually represents the total
installation material for the system. Additionally, Ericsson support is only a phone call
away.

2.2.2 General
The MD110 often consists of only one stack built of modules placed upon each other. It
may also contain an extra stack for power equipment. A stack can consist of up to four
modules. Each stack is mounted on the base. The right hand part of the module has a chute
for cabling. The uppermost module has a top cover of ABS plastic. The rear part of the
cover has a ventilation grating for heat dissipation.
The module stack is cooled by free convection. The magazines in a stack are cooled in
parallel, i.e. the evacuated air from each magazine is led via an air-duct behind the
magazines upward to the ventilation grating at the top of the stack.
The Line Interface Module (LIM) can consist of three types of modules, Processor Switch
Module (PSM), InterFace Module (IFM) and All Contained Module (ACM). For
electromagnetic interference protection the magazines contains a shielded cage with a
removable metal front cover. ACM is a PSM with batteries and an AC/DC unit.
Each PSM and IFM contains a magazine with board slots. At the rear of each slot is a
connector that is attached to a common backplane. The backplane is a printed circuit board
that contains the data and control system bus structure. The device bus carries speech and
data to and from the device boards. The process bus carries control data between the device
processors. Data is multiplexed onto these buses via time slot assignments to physical
board positions to allow maximum flexibility in the placement of device boards in the
magazine.
Certain device boards have fixed positions within specific modules. The remaining board
positions are given 8, 16, or 32 time slots. This architecture facilitates easy system
installation, flexible board placement and expansion.
The LIM switch can control 1024 time slots, divided into 256 time slots per magazine.
Each board position ending with a 0 has 32 time slots. Positions ending with 2 have 16
time slots and positions ending with 1 or 3 have 8 time slots.
The following figure shows how the board positions within a magazine can be used
depending on the required number of time slots per installed board:
00 10 20 22 30 32 40 42 50 52 60 62 63 70 71 72 73 Board position

time slots
Explanation: Position 00 and 10 can accommodate a board requiring 32 or less time slots
each. Position 20-60 can share the time slots with the position on the right (16/16), and
positions 62-63, 70-73 can share the time slots 8/8.
If a board requiring 32 time slots is placed in position 20, 30, 40, or 50, the next board
position is blocked (x). If the same board is placed in position 60, the next two positions are
blocked and if placed in position 70 the next three positions are blocked. Boards requiring
16 time slots placed in position 62, 70 or 72 block the next board position.

2.2.3 Processor Switch Module (PSM)
All common control functions are handled by the LSU board in the PSM. The operating
system and allocation system hardware, as well as hard disk (software backup media) is
contained in the LBP20 magazine within this module. Memory capacity in the stackable is
64Mb and is available as an integral part of the LIM Processor Unit (LPU5).
There are 9 accessible universal board positions for interfaces of any type of internal or
external devices, e.g. extension line boards and trunk line boards, depending on system
configuration.
Voltage for ringing analogue telephones is provided either by the RG5DC unit, which also
replaces the PU5DC unit, or the Ringing Equipment Unit (REU) in the PSM. If the system
is without analogue telephones, the REU does not need to be installed.
In the PSM, the LBP20 magazine has fixed positions for the following circuit boards:

2.2.4 Interface Module (IFM)
The IFM provides switching for 256 time slots. The hardware for the IFM is contained in
the LBP20 magazine within the module. There are 17 accessible universal board positions
for interfaces of any type of extension, trunk access or other types of board, depending on
system configuration. Again, the PU5DC unit can be replaced by the RG5DC unit.
In the IFM, the LBP20 magazine has fixed positions for the following two circuit boards:

2.2.5 Power Module (PWM)
The PWM is an internal power supply that converts mains 220-240V AC power to
-48VDC and interfaces with the PU5DC or RG5DC boards, which supply power in each
module. One PWM can support up to four modules (one PSM and three IFMs). It can be
equipped with four battery blocks that form a 26 Ah battery back-up, one battery fuse unit,
and two AC/DC units (12.5A each). This power supply will maintain operation of the
exchange for one to three hours in the event of mains power failure.

2.2.6 Power Battery Module (PBM)
The PBM is a unit to be used when additional battery power is required to extend the
battery back up time. The unit can be equipped with one or two batteries. Each battery
contains four battery blocks and will extend the operation time of the exchange with
another 26 Ah in event of mains power failure, e.g. in total a maximum of 26 + 26 + 26 =
78 Ah.

2.2.8 Configuration Capacity
Because of its modularity and flexibility, the MD110 can be installed in many different
configurations. As the number and use of extension lines, trunk lines and additional
equipment are specific for each installation, the configuration capacity is dependent on the
customer’s configuration.
2.3 FACILITY PLANNING
When installing an MD110, the following specific environmental conditions for proper
operation should be taken into consideration.
2.3.1 Temperature and Humidity
To prevent equipment damage and system degradation, the relationship between
temperature and air humidity should not cause condensation. After power is applied to an
MD110 system, the equipment and the ambient room temperature/relative humidity must
be stable within the operating ranges. Measurements should be taken at least 1.5 m above
floor level and at least 0.5 m from any heat-dissipating object.
Temperature Range: 5°C to 40°C 41°F to 104°F
Relative Humidity Range 20% to 80%
2.3.2 Heat Dissipation
The typical heat dissipation for the stackable LIM (four modules) is 115-350 Watts (393-
1195 BTU). The various LIM modules use convection cooling for heat dissipation without
using internal fans. This technique provides all the necessary cooling for most applications,
minimizing or eliminating the need for air conditioning if the ambient air temperature is
satisfactory.
2.3.3 Air Filtration and Ventilation
The type of air filtration required for proper operation depends upon the dust and other
particulate matter concentrated in the equipment room. If salt air, dust, smoke, corrosive
gases or other degrading pollutants are present in the atmosphere, a prefilter and a main
filter in the room ventilation intake is required.
2.3.4 Lighting
The MD110 should not be exposed to direct sunlight.

2.3.5 Floor Loading
Floor loading is based on an aisle working space of 1 m in front of the module stack or
cabinet and is derived from the total weight of a four-module stack.

PBM 400 mm 600 mm 355 mm 105 kg with two optional backup batteries installed
Base 230 mm 600 mm 355 mm 11 kg
2.3.7 Floor Plans
When considering a floor plan, it is necessary to anticipate the system growth at each site to
minimize future problems. Space requirements for customer supplied external power
equipment should be evaluated as well. In addition, the MD110 should not be installed in a
location where water sprinklers are present.
Some possible floor plans are shown in the following examples:
The stacks must be anchored to the floor or the wall depending on the floor plan used. To
ensure safe operation, adequate free space should surround the equipment. The free space
area requirements are:
Minimum aisle area in front of a module stack: 60 cm
Minimum free space on left and right side of each stack or row: 20 cm
Static electricity and electro magnetic radiation is harmful to the system, so make sure to
protect the system and yourself from that kind of disturbances by using anti static
wristband whenever touching a circuit, and allways keeping the steel front cover on the
magazines while in service.

2.3.8 Electrical Requirements
MD110 system operates on -48VDC that is normally supplied by rectifiers provided with
the system. The AC input power source to the rectifiers is 220-240VAC. Wall sockets must
be equipped with protective earthing.
Battery backup may also be provided in accordance with the customer's specification for
expected hours of operating time during failure of the main AC power source. If the -48V
DC power is supplied by the customer, ensure that the MD110 quality standards are met.
2.3.9 Earthing
The MD110 requires an isolated, single-point earth system. This electrical bonding is
centralized at the system earth bus bar. Continuity should measure less than, or equal to 4
ohms between the system earth bus bar and earth (<4 ohm earth).
The ideal single earth point is a dedicated, independent external earth point such as a
driven terminal, but a cold water pipe or principle building earth bar or plate are
acceptable. A proper external earth point should be connected to the exchange room earth
point of entry.
Note: Be sure to comply with local regulations.
2.3.10 Cabling
2.3.10.1 General
External cables to the stackable modules are routed through the uppermost module or
through an opening under the base. A chute on the right side of each module is used for
routing external cables and cables between other modules. All cable connectors are
accessible from the front of the module.
To eliminate noise or transient spikes, it is preferable not to place MD110 cabling in the
same conduit as non-MD110 cabling. Unshielded cabling can cause noise induction, which
can adversely affect the system’s performance. If necessary, EMI/RFI filters should be
installed to eliminate noise or transient spikes.
Note: To prevent disturbances to or from other electronic equipment, certain cables must be
wrapped to a toroid core. This is directed and shown in Chapter 5 Installation.
Take the following steps to ensure proper cable distribution, routing and terminating
techniques:
1. Complete all construction modifications to the exchange installation areas before
placing or installing any equipment (e.g. walls, floors, cable ducts, room-to-room
portals, sub-floor/overhead access holes, etc.).
2. Plan cable routing and lengths.
3. Minimize exposed cables.
4. Meet all applicable building codes, telephone company requirements and regulations.
Incoming cables are to be laid in a cable chute or clamped directly to the wall, and
then run downward to the top of the LIM, or from the floor in a raised floor system.

2.3.10.2 Cable Connectors
Plug-ended and plug-to-plug type cables are used. The cables are wire-wrapped or soldered
to connector units, which are divided into 1/4 sections. These connects to the front of the
boards. 1/4, 1/2, 3/4, and 1/1 cable connectors are used.

2.3.10.3 Labelling
Internal cables
Internal cables within the LIM are labelled with product codes made up of
letters and digits. The example beside shows the code for the 1000 mm
long cable between PU5DC in magazine 0 and PU5DC in magazine 1.
Each cable connector is equipped with a tag. On the top of the tag is the
host location to where the connector is attached. On the underside is the
receiver location to where the other end of the cable is attached. For
example, the top of the tag in the figure reads: 0A170*3
à 0 = Magazine number
à A = Top half of the connector on the board♦)
à 170 = Board position (PBA position in modules;
1 module = 2,54 mm)
à *3 = 1/4 section to which the cable connector is attached
This means that the connector is connected to the third 1/4 connector position of the top
half of the board in magazine 0, board position 170.
The underside of the same tag is labelled with the “to” position in the same LIM: 1A170*4
à 1 = Magazine number
à A = Top
à 170 = Board position
à *4 = 1/4 section to which the cable connector is attached
♦) An internal cable labelled B means that the cable is connected to the bottom half of the board.
Peripheral cables
Peripheral cables to MDF, modem etc., must be labelled using label set SVH 277 025/1.
This set is a standard set to be used for larger exchanges as well, e.g. only some of the
labels will be used.
The label for cables such as LIM to MDF and PCM-LINK to MDF,
indicates the position of the cable connector in the LIM. For example, a
cable to the MDF might be marked as follows:
à L1 = LIM number 1
à /1 = Cable number for the device board
Parameter values 1-40
à A = Cable connector parameter (A = connected to the device board)
The other end of the cable, at the MDF, must be labelled with the same figures but with
(M) instead of (A). See figure.
Attach the label in the MDF side i.e. as shown in the figure.
Instructions on how to label the various cables to MDF are specified in the supplied
document 2/1951-IPA 103 xxxx (customer specific numbered).

2.5.5 Battery Backup Installation
The MD110 may be supported by internal or external battery backup depending on
customer preferences.
2.5.5.1 Internal Battery
The internal 48V battery is housed in the PWM. The battery consists of four 12 V battery
blocks. If extended battery backup time is required, one or two extra 48V batteries are
housed in the PBM. For safety reasons the battery blocks are not installed on delivery.
The battery blocks are to be installed and cabled as follows:
1. Place the battery breaker on the BFU2 in the PWM in the off
position.
2. Place the battery switch on the battery boxes in the off position.
3. Remove the battery box cover plate. Two of the screws must be
reached through the two holes to the left on the cover plate.
4. Cable each pair of batteries in series with cables TRE 990 122/2 as
shown in the figure.
Note: Fasten the cable terminators to the battery poles in such a
way that no part of the uninsulated terminator sticks out from the
battery (to prevent risk of short circuits when the batteries are slid
into the compartment).
5. Place each pair of cabled battery blocks on the shelf in the battery
box. In order to complete the remaining cabling, do not push the battery blocks to the
back of the box.
6. Connect the remaining cables to the terminals and terminal blocks as shown in the
following figure. Be sure to respect battery polarity.
7. Protect the battery terminals with the insulation covers fastened at the end of each cable.
8. In the PWM only: Place the termic probe RNV 991 3017 at the top of the battery
blocks and clamp the probe cable from the AC/DC unit to a battery cable with cable
clamp SET 103 01 as shown in the figure. Depending on the type of AC/DC unit, the
probe cable is either of type TSR 901 0319/800 or of type TSR 901 0311/800.
9. Slide the battery to the rear of the compartment.
10. Keep the battery box covers open.
