Space Requirements
This is a single-width, half-height module. Actual space requirements depend on
whether the module is installed in a standard Prisma II or a Prisma II XD chassis.
Prisma II Chassis Installation
When installed in a standard Prisma II Chassis, the module is placed in a host
module and then inserted into the chassis in slots 5 through 16.
If the module occupies the upper host module position, its slot number is the
same (5 through 16) as that of the host module.
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 no matter
how the chassis is configured.
Prisma II Chassis Style
The standard Prisma II chassis may be configured as front-access or rear-access
depending on the system you have purchased. Power, RF input or output, and other
connectors may be located on either the front or rear of the 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.
