Preparing for the Installation
Verifying the hardware configuration
Checking the of the chassis
Figure 1-7 shows the back of the Stinger MS+ chassis.
Figure 1-7. The Stinger MS+ (rear view)
Unless LIMs with integrated protection circuitry are used, each LIM installed in the
unit must have a corresponding LPM installed in the matching slot at the back of the
unit. The top slot in the back of the Stinger MS+ is reserved for a trunk module; it
cannot be used for an LPM. Slots that are not occupied by modules must be masked
with blank covers to ensure proper air flow through the unit.
Verifying the trunk module
The top slot in the rear of the Stinger MS+ chassis can contain a trunk module. The
trunk module supports connection to either optical or copper media, depending on
the type of module supplied. This top rear slot is labeled, “TM.” To maintain the
uniformity across the Stinger product line, this slot is logically referred to by the
TAOS software as slot 17.

Figure 1-8 shows the location of the optical fiber connections on an OC3-ATM trunk
module.
