Preparing for the Installation
Stinger MS+ overview
The Stinger MS+ chassis is designed for use in a central office environment where
rack space is limited, or the local user population does not require a larger Stinger
FS+ or Stinger LS unit. The Stinger MS+ uses a mid-plane design, similar to the larger
Stinger FS+, and can be equipped with the control modules, trunk modules, LIMs,
and LPMs that are used in the Stinger FS+. (For more environmental information,
see “Site specifications”on page C-4.)
The Stinger MS+ chassis
The Stinger MS+ chassis, shown in Figure 1-1, has horizontal slots in the front and
rear that engage the midplane bus. The front of the Stinger MS+ chassis has five
horizontal slots for modular plug-in components and two lower bays for redundant
power filters. The horizontal slots accept up to four line interface modules (LIMs) and
one control module in a designated slot. Unless LIMs with integrated line protection
are used, each LIM must be matched by a line protection module in a corresponding
slot in the rear of the chassis. A single trunk module can also be installed a designated
slot in the rear of the chassis.

Stinger®MS+ Getting Started Guide 1-3
Modular plug-in components
The Stinger MS+ chassis supports the following modular plug-in components:
■The control module—A single control module is installed in the front of the
chassis provides a TAOS management interface for configuration and
management of the unit. The control module manages the operation of the
Stinger MS+ unit and the traffic through the unit. It also maintains information
about the configuration of the unit.
■LIMs—Up to four line interface modules (LIMs) are installed in the front of the
chassis to provide the internal interfaces that are configured to provide service for
individual DSL subscriber lines.
■Line protection modules (LPMs)—Up to four line protection modules (LPMs) are
installed in the rear of the chassis to provide physical connection points for the
DSL subscriber lines associated with the LIMs in the front of the chassis. The
LPMs also provide protection for the unit from transient conditions on the
subscriber lines.
■The trunk module—A single trunk module or trunk aggregation module (TRAM)
is installed in the top slot in the back of the chassis. This can be any of the trunk
modules that can be installed in the Stinger FS+. Including:
–OC3-ATM trunk module
–DS3-ATM trunk module
–E3-ATM trunk module
–OC3 TRAM module
–OC12-ATM trunk module
–Fast Ethernettrunk module
■Power filters—Two power filters, installed in the front of the chassis, provide
redundant inputs for power to the Stinger MS+.
■The alarm module—A small module provides external connections for
monitoring the major and minor alarm status of the unit. It also provides
connections for an external BITS signal.
■The cooling module—A replaceable module contains fans that circulate air
through the unit, and the electronics to control and monitor their operation.
Selecting an installation site
Before you choose a location for the Stinger unit, read and follow the site and
electrical requirements defined in the Edge Access and Broadband Access Safety and
Compliance Guide.
Select the setup location carefully. Keep in mind that the unit requires sufficient
clearance for cabling, module replacement, and proper ventilation (see “Space
requirements”on page C-5). You can rack-mount the Stinger MS+ in a standard
equipment cabinet that is 19 inches or 23 inches (48.26cm or 58.42cm) wide (see
“Mounting the unit”on page 2-1).

Preventing static discharge damage
Modules and semiconductor devices in general can be easily and permanently
damaged due to electrostatic discharge during installation or removal. A person
walking across a floor can generate electrostatic voltages in excess of 5000V.
Although you might not notice a discharge of less than 3500V, discharges below 100V
can damage semiconductor components.
You can destroy a component without noticing any electrostatic discharge. Because
these discharges have very little current, they are harmless to people.
To prevent damage to components from electrostatic discharge, always follow the
proper guidelines for equipment handling and storage.
Use a wrist strap
To reduce the static potential on your body by proper grounding, wear an approved
antistatic wrist strap (Figure 1-3) when installing, removing, or handling modules, or
while handling any Lucent device containing semiconductor components.
!Caution Correct use of an approved antistatic wrist strap is the only reliable way to
prevent damage to components by electrostatic discharge from your body
