P3Csi, P3Cmi, P12Csi, And P12Cmi Modules - Extreme Networks e” series Hardware Installation Manual

BlackDiamond 6800 Series I/O Modules

P3cSi, P3cMi, P12cSi, and P12cMi Modules

Extreme Networks offers the PoS module in the following configurations:
• P3cMi: four OC-3 multimode, short-reach optical interfaces
• P3cSi: four OC-3 single-mode, intermediate-reach optical interfaces
• P12cMi: two OC-12 multimode, short-reach optical interfaces
• P12cSi: two OC-12 single-mode, intermediate-reach optical interfaces
NOTE
The "c" in the names of the modules indicates that the optical interfaces on these modules operate in
concatenated mode, which enables all the bandwidth to be devoted to a single payload stream.
The PoS module has the following key components:
• Two high-performance network processors
• A General Purpose Processor (GPP) subsystem
The network processors are programmable devices that participate with the Extreme "i" chipset to
support expanded functionality, features, and flexibility.
The GPP subsystem handles system control and I/O module management functions. The GPP
subsystem resides outside of the I/O module data path to optimize performance.
