Cisco Cisco Prisma II EDR Receiver 安装指南

 

Chapter 2        Module Installation 

48 

 

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. 

 

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. 

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. 

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.
