SAFETY GUIDELINES

The following safety guidelines are presented to help you avoid injury to yourself and avoid damage to the
equipment. These guidelines are recommended when working with any equipment that connect s to electrical power
or telco wiring.

• Locate the emergency power-off switch for the area in which you are working before beginning any proce­dures requiring access to the telco-style equipment rack. Then, if an electrical accident occurs, you can
quickly shut off the power.

• Disconnect all power before doing the following:

– Installing or removing the shelf
– Working near power supplies

• Never work alone if potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Never perform any action that creates a potential hazard to people or makes the equipment unsafe.

• Carefully examine your work area for possible hazards, such as moist floors, ungrounded power extension
cables, and missing safety grounds.

• Keep the work area free of obstructions before, during , and after shelf installation.

• If an electrical accident occurs, proceed as follows:

– Use caution; do not become a victim yourself.
– Turn power off to the telco-style rack that the shelf is located in.
– If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and

then call for help.

– Determine if the victim needs rescue breathing or external cardiac compressions; then take appropriate

action.

• Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appro­priate consideration of equipment nameplate ratings should be used when addressing this concern.

• Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g., use of power
strips).

• The following precautions may appear in this manual in procedures that, if performed incorrectly, may harm
you or your equipment.

CONNECTING TO HDSL, HDSL2, AND HDSL4 CIRCUITS

The following paragraphs provide information on making DSX-1 and HDSL, HDSL2, and HDSL4 connections to the
HMS-318 List 3 shelf.

Plug-in Connections DSX-1 and HDSL, HDSL 2, or HDSL4

DSX-1 connections to the HMS-318 List 3 shelf can be made through the HMS-318 List 3 shelf’s rear-panel 50-pin
Amphenol-type male connectors P1, RCV to DSX (labeled CO PAIR 1) and P2, XMT from DSX (labeled CO PAIR

2). HDSL, HDSL2, or HDSL4 connections to the shelf can be made through rear-panel 50-pin Amphenol-type male
connectors P3, HDSL Loop 1 (labeled SPAN PAIR 1) and P4, HDSL Loop 2 (labeled SPAN PAIR 2). All of these
connectors (P1, P2, P3 and P4) are described in the section titled “HMS-318 List 3 Rear View” on page 1-3.

Wire-Wrap Connections DSX-1 and HDSL, HDSL2, or HDSL4

DSX-1 and HDSL, HDSL2, or HDSL4 connections can be made to the individual card connectors through the HMS­318 List 3 shelf’s rear-panel wire-wrap pins (0.045-inch square/1.14 mm). Straps for cable dressings and a
protective Lexan rear cover are provided with each shelf. Figure 1-5, Figure 1-6, and Figure 1-7 show the HLU card
slot pinouts for HDSL, HDSL2, and HDSL4, respectively on the HMS-318 List 3 shelf rear panel.

Each circuit card is identified by name and list ID (for example, HLU-319 HiGain G.703 L1). The name and list ID are
labeled on the upper portion of the front panel. All circuit cards are inserted straight into the slot, using guide pins to
align each circuit card.

ATTENTION

To ensure against da mage to electronic components, ESD protection must be employed in the
handling of all circuit cards. Therefore, antistatic discharge wrist-straps should be used
whenever circuit cards are being removed or replaced. The antistatic discharge straps should be
connected to frame ground. At all other times (shipping, storage, and so forth), these circuit cards
should remain in static-shielding protective bags (for a description of card preventive measures,
see Appendix C: ”Circuit Card Preventive Measures” on page C-1).

HEAT DISSIPATION FACTORS

The HMS-318 List 3 shelf is a 12-inch (30.48 cm) deep individual CO equipment shelf with open-fa ced mountings for
natural convection cooling. The maximum heat dissipation for open-faced, natural convection-cooled mountings is
limited to 134.7 Watts per square foot as defined in Section 4.1.4 of the NEBS standard for Physical Protection
(GR-63-CORE) for all equipment placed in a CO environment.

The heat dissipation footprint of an HMS-318 List 3 shelf is approximately 5.9 square fee t. Therefo re, the maxim um
permissible heat dissipation per rack is 5.9 square feet x 134.7 Watts per squar e foot equals 790 Watts.

The maximum allowable heat dissipation for each telco-style equipment rack is:

• 790 watts for a 19-inch (48.3-cm) wide rack

Figure 1-11 shows a typical example of a CO equipment rack layout using HMS-318 List 3 shelves. The figure

shows a rack with a fuse panel, eight HMS-318 List 3 shelves, each separated by a two rack space baffle with the
remaining shelf space open. As the figure illustrates, baffles should be placed between each shelf to reduce the
chimney heating effect (see “Air Flow Guidelines” on page 1-15 for further information about cooling the HMS-318
List 3 shelf).

Outdoor cabinet applications require forced air to ensure proper cooling.

December 20, 2004 Chapter 1: Product Description

AIR FLOW GUIDELINES

To ensure adequate air flow through the telco-style equipment rack, it is recommended that you maintain a
clearance of at least 6 inches (15.2 cm) in the front and the back of the rack at all times.

If airflow through the telco-style equipment rack and the shelves that occupy it is blocked or restricted, or if the
ambient air being drawn into the rack is too warm, an over temperature condition within the rack and the shelves that
occupy it can occur.

The site should also be as dust-free as possible. Dust tends to clog the shelves, reducing the flow of cooling air
through the telco-style equipment rack and the shelves that occupy it and increasing the risk of a n over temperature
condition.

Additional rack-mounting guidelines are:

• Install the shelf in an enclosed rack only if the rack has adequate air flow (see Chapter 2: “Installation” on

page 2-1); install the shelf in an open rack whenever possible.

• The proper use of heat (air) baffles inside an enclosed rack can help ensure adequate shelf cooling.

INSTALLATION

This section provides specific information about preparing your site for insta llation. Included are specific prep aratory
information, safety guidelines, specific rack-mounting guidelines, adapter bracket mounting, rack mounting, DSX
and HDSL or S pan Powered xDSL connections, and power and alarm connections. Once you have completed the
basic installation and verified that your shelf is functioning properly, you can refer to the instruction manuals for the
individual modules (HLU, HMU, or LPS-300C). These instruction manuals provide comprehensive config uration and
technical information that will help you further define the parameters to meet your particular requirements (see

“Related Publications” on page ix).

BEFORE YOU BEGIN

Before installing the HMS-318 List 3 shelf, it is important to prepare for installation by:

• Preparing the site (site preparations) or reviewing the installation plans by establishing a Method of
Procedure (MOP)

• Unpacking and inspecting the shelf shipment

• Gathering the tools and test equipment required to properly install the shelf.

Site Preparations

Typically, you should have prepared the installation site beforehand. As part of your pre p ar atio n, obtain a floor plan
of the site and the Central Office (CO) or telco-style equipment rack (either EIA with 1.75 in. mounting spaces or
WECO with 2 in. mounting spaces) where the HMS-318 List 3 shelf will be housed. Determine the location of any
existing shelves and their interconnections, including communications and power. The -48VA and -48VB busses
provide the -48V shelf battery feed. Each bus should be fused at 15 Amperes. All personnel involved in the
installation of the shelf, including installers, engineers, and supervisors, should participate in the preparation of a
MoP for approval by the customer.

Method of Procedure

An example of a Method of Procedure (pre-installation checklist of tasks and considerations that needs to be
addressed and agreed upon before proceeding with the installation) is given below:

• Assign personnel.

• Determine protection requirements for personnel, equipment, and too l s.

• Evaluate potential hazards that may affect service.

• Schedule time for installation.

• Determine any space requirements.

• Determine any power requirements.

• Identify any required procedures or tests.

• On an equipment plan, make a preliminary decision that locates each of the HMS-318 List 3 shelves that you
plan to install.

• Read this manual.

• Modify the preliminary plan, if necessary.

• Verify the list of replaceable parts for the installation (screws, bolts, washers, and so on) so that the parts are
identified (see Table 2-1 on page 2-2).

• Check the required tools list to make sure the necessary tools and test equipment are available (see Chapter 2:

“Required Tools” on page 2-3).

• Purchase necessary parts.

• Perform the installation (see Chapter 2: “Safety Guidelines” on page 2-4).

Unpacking and Checking the Contents of your Shipment

The shipping package for the HMS-318 List 3 is designed to reduce the possibility of product damage associated
with routine material handling experienced during shipment. To reduce the potential damage to the product,
transport the shelf in its ADC-specified packaging. Failure to do so may result in damage to the shelf. Also do not
remove the shelf from its shipping container until you are ready to install it. Refer to “Inspecting Your Shipment” on

page xii for unpacking instructions.

Note: Do not discard the packaging materials used in shipping your HMS-318 List 3 shelf. Y ou will need the

packaging materials in the future if you move or ship your HMS-318 List 3 shelf.

SAFETY GUIDELINES

The safety guidelines (see Chapter 1: “Safety Guidelines” on page 1-iv) are provided to help ensure your safety and
to protect your equipment. The list on page iv may not identify all potentially hazardous situations in your working
environment, so be alert and exercise good judgment at all times.

MOUNTING THE HMS-318 LIST 3 SHELF

Each HMS-318 List 3 shelf has a hardware kit. The rack adapter brackets are attached to the HMS-318 List 3 shelf
at the factory. They are supplied with the shelf to allow mounting on 19-inch (48.3-cm) telco-style EIA or WECO
equipment racks. Select the appropriate position for the brackets (2 or 5 inches) and mount the shelf to the bracket
as described in the Chapter 2: “Adapter Bracket Mounting Procedure (19-inch Telco-style Equipment Rack)” on

page 2-5 and the Chapter 2: “Adapter Bracket Mounting Procedure (23-inch Telco-style Equipment Rack)” on
page 2-5. When installed in an EIA rack, a total of three 1.75-inch (4.4-cm) mounting spaces [5.25 inches (13.3 cm)

of vertical rack space] are required for mounting an HMS-318 List 3 shelf. When installed in a WECO rack, a tot al of
three 2.0-inch (5.08-cm) mounting spaces [6 inches (15.2 cm) of vertical rack space] are required for mounting.

ETSI adapter brackets are included for inst allation of the HMS-318 List 3 sh elf in an ETSI-style equipment rack (see

Chapter 2: “Adapter Bracket Mounting Procedure (ETSI-style Equipment Rack)” on p ag e 2-6).

IMPORTANT

!

Special Rack-Mounting Precautions

Special rack-mounting precautions must be followed to ensure safety. They are:

• Never wear loose clothing, jewelry (such as rings, bracelets, or chains), or other items that could get caught in
the shelf housing during handling and use.

• When mounting the shelf to a telco-style rack, ensure that the rack is bolted to the floor.

• Since you will probably be installing more than one shelf into the rack, ensure that the weight of all the shelves
installed does not make the rack unstable.

IMPORTANT

!

• As mentioned in “Air Flow Guidelines” on page 1-15, maintain a clearance of 6 inches (15.2 cm) at the front and
back of the shelf to ensure adequate air int ake and exha ust.

• Avoid installing the shelves in an overly congested rack (see “Heat Dissipation Factors” on page 1-13). Air flow­ing to or from other shelves in the rack might interfere with the normal flow of cooling air through the shelves,
increasing the potential for over temperature condition s wi thin the shelves.

• Allow at least 19 inches (48.7 cm) of clearance at the front and back of the rack for shelf mainten ance.

• Follow your local practices for cable management. Ensure that cables to and from the shelves do not impair
access to perform equipment maintenance or upgrades.

Clearance above and below the shelf must be allowed for cooling air to be drawn in the front and
circulated through the shelf and out. A heat (air) baffle must be used between shelves to ens ure
that heated air is dissipated appropriately (see “Air Flow Guidelines” on page 21 for detailed
information about air flow guidelines).

Some telco-style racks are also secured to ceiling brackets, if necessary, due to the weight of the
equipment in the rack. Make sure that the rack you are using to install the shelves is secured to
the building structure.

December 20, 2004 Chapter 2: Installation

Adapter Bracket Mounting Procedure (19-inch Telco-style Equipment Rack)

Adapter bracket placement depends on the type of telco-style rack you plan to use to install the HMS-318 List 3
shelf. First, check the mounting adapter brackets on the shelf to determine whether the factory-installed
configuration is correct for the planned telco-style equipment rack installation. The following procedure describes
how to install the adapter brackets. Threaded holes on the HMS-318 Li st 3 shelf are str ategically located to p osition

Power and Frame Ground Procedure

IMPORTANT

!

To avoid voltage differences from building up between the shelf ground (GND) bus and the
ground pins of the management terminal that connects to the RS-232 ports, connect the shelf
ground pins and the terminal ground bus to the TB1 FGND (frame ground) pin.

Step Action

1 Use locally approved practices to connect #12 AWG (minimum) power wiring from -48Vdc Office Battery

to -48VA and -48VB terminals on TB1-1 and TB1-2 (see <Cross-Ref>Figure 2).
2 Connect #12 AWG (minimum) power wiring from the Battery Returns to BAT RTN terminals on TB1-3

and TB1-4 (see <Cross-Ref>Figure 2).

Note: Slots 1 through 11 on the HMS-318 List 3 shelf are powered by the -48VA bus. Slots 12 through 22

are powered by the -48VB bus.

In the HMU/HLU configuration, the HMU-319 is diode-OR’ed to both power busses to guard against power

failure in the event that one power supply is lost. This feature requires the two ground (GND) terminals to

be connected on the HMU card.

Alarms Procedure

Note: As described in “Power and Alarm Connections” on page 7, the HMS-318 List 3 shelf provides alarm

outputs in the form of an Alarms wire-wrap field. This field consist s of a three-pin wire-wrap header for alarm

management. Before connecting the alarm inputs, you must first determine whether the external alarm

equipment requires either an NO or an NC circuit to pass an alarm.

Step Action

1 Use locally approved practices to connect the alarm inputs to the Alarms wire-wrap field (see Figure 2-3

on page 2-12).

Note: The HMU-319 is required for NO and NC alarm operation.

LTPH-UM-1261-01 2-11

Chapter 2: Installation December 20, 2004

Optional Fan Alarm Procedure

Note: The FAN terminals wire-wrap field provide s access to the Normally Open (NO), Form A fan relay

contact located on the HMU-319 management u nit. A temperature monitor activates this fan relay when the

shelf temperature exceeds 45°C (±1°C) and deactivates the relay when the temperature drops below 35°C

(±1°C). If the temperature exceeds 77°C (±1°C) a critical alarm is also generated. The critical alarm reset s

when the temperature drops below 40°C (±1°C).

CIRCUIT CARD PREVENTIVE MEASURES

This appendix describes the preventive measures that should be observed for the following:

• Handling and storing of circuit cards.

• Installing/replacing circuit cards sensitive to static electricity.

HANDLING CIRCUIT CARDS

Damage to circuit cards, particularly those that are sensitive to st atic electricity, may occur at any time. Follow these
safeguards when handling circuit cards.

• Avoid dropping a circuit card.

• Hold circuit card by ejector tabs or card edges; avoid handling components or the connector pins.

• Avoid unnecessary removal and insertion of circuit cards. Contact life is reduced by repeated removals and
insertions.

• Avoid touching circuit card contacts. Handling leaves dirt and grease, causing unit failure and reduced contact
life.

• Wear a properly grounded antistatic discharge strap when handling circuit cards that are sensitive to static
electricity. This strap consists of an expandable wrist strap and grounding cord; its function is to rapidly dissi­pate charges to ground.

• Periodically check the resistance value of the antistatic discharge wrist strap. The resistance measurement
should be between 1 and 10 Mohms.

Note: Alternate grounding methods can be used; for example, conductive carpet, conductive shoes, or heel

grounders.

STORING CIRCUIT CARDS

Spare circuit cards must be left in the original shipping container until required. To prevent damage to circuit cards
while they are in storage, the following necessary precautions must be observed:

• Store circuit card in a dust-free environment. Dust particles will scratch the circuit card contacts when inserted
in a connector.

• Sto re circuit card in a dry en vironment at room temperature. Excessive heat will cause the circuit card to warp.

• Place circuit card in shipping container (if available) after removal. Otherwise, carefully place circuit card in a
static-shielding protective bag.

INSTALLATI ON/REPLACEMENT

To prevent electrostatic damage, the following conditions apply during the installation/replacement of circuit cards
that are sensitive to static electricity:

• All circuit cards must be enclosed in static-shielding protective bags for transport ation to and from the location.

• Upon installation/replacement, installers must wear a properly grounded antistatic discharge wrist strap.

Note: Whenever possible use the original static- shielding bag, padding, and box in which the circuit card

was received. If the original material was lost, use suit able packing.

Appendix C: Circuit Card Preventive Measures December 20, 2004

Circuit Card Ejector T a b or Built-in Thumb Hold

Most circuit cards have an ejector tab that is used to assist the installer in inserting and removing each circuit card.
These ejector tabs are typically located at either the top or bottom of the circuit card. Other types of cir cuit cards
have a built-in thumb hold for gripping the card. Follow the procedure given to remove and insert a circuit card.

Removing Circuit Card

DANGER

Contacting circuit card components or traces can result in an electrical shock even after removal
from the shelf.

Wear properly grounded anti-static wrist-straps when removing a circuit card. At all other times

ATTENTION

(shipping, storage, and so on) keep the circuit cards in their protective bags.

Step Action

1 Remove any front-panel cables from the circuit card.

Note: Note the positions of all cables and slots each circuit car d resides in for later replacement.

2 Grasp the circuit card at the top or bottom ejector tab or the built-in thumb hold and pull forward to release

it from its connection. A slight amount of force may be required to unseat the circuit card.

Inserting Circuit Card

Wear properly grounded anti-static wrist-straps when inserting a circuit card. At all other times

ATTENTION

(shipping, storage, and so on) keep the circuit cards in their protective bags.

Step Action

1 Holding the circuit card by its ejector tab or built-in thumb hold, insert into the shelf housing. Ensure that

the circuit card connection is firmly seated.

2 Attach any front-panel cables to the circuit card.

Note: To prevent confusion, it is sometimes important for the installer to note in which slot each circuit card

resides and in which connector each cable resides.
