INSTALLATION
This section provides specific information about preparing your site for installation. Included are specific preparatory
information, safety guidelines, specific rack-mounting guidelines, adapter bracket mounting, rack mounting, DSX
and HDSL or Span 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 configuration 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 preparation, 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 tools.
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).
