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 Ethernet trunk 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).
