Power Requirements; Space Requirements - Cisco Prisma II Installation Manual

Chapter 2 Module Installation

Power Requirements

All Prisma II application modules receive their electrical power from the chassis. The
modules may be installed with the chassis under power.
Note: It is recommended to install no more than 20 QEDR receiver under Prisma II
Standard chassis power supply.

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.
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.
