Power Requirements
Prisma II modules receive their electrical power from the Prisma II Chassis.
The module may be installed with the chassis under power.
Space Requirements
This is a single-width, half-height module. Actual space requirements depend
on whether the module is installed in a Prisma II standard or a Prisma II XD
chassis.
Prisma II Standard Chassis Installation
When installed in a Prisma II standard chassis, the module is placed in a host
module and then inserted into the chassis in slots 5 through 16.
¾
If the module occupies the upper host module position, its slot number is the
same (5 through 16) as that of the host module.
¾
If the module occupies the lower host module position, its slot number is 16 plus
the host module slot number, or 21 through 32.
Slots 1 through 4 are usually reserved for the power supplies. If an ICIM is
installed, it occupies slots 15 and 16. If an ICIM is not installed, any other
module (or host module) can occupy these slots.
Slots 2 and 4 are reserved for an internal power supply, if installed. If an
internal power supply is not installed here, any other module (or host
module) can occupy these slots.
Prisma II XD Chassis Installation
When installed in a Prisma II XD Chassis, the module is inserted directly into
an available application module slot on the chassis front panel. The
application module slots are numbered 1 through 16.
The chassis power supplies and ICIM are installed in dedicated slots on the
chassis back panel, so slots 1 through 16 are available for application modules
regardless of chassis configuration.
Standard Prisma II Chassis
The standard Prisma II Chassis may be configured with front or rear
connectors depending on the system you have purchased. Power, RF
input/output, and other connectors may be located on either the front or rear
of the Prisma II Chassis. Connections to the chassis serve the same function
and are made in the same manner regardless of the location of the connectors
or chassis configuration.
