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.
