Packet Over SONET Module Installation and User Guide 2-3
Preparing for Installation
The MSM software package is compatible with the PoS module software package when
the following conditions are true:
• Base ExtremeWare version numbers match
• Technology release names match
• Extended major version numbers match
• Extended minor version number of the MSM software package is equal to or greater
than the extended minor version of the PoS module software package
The extended build number is ignored for compatibility comparisons.
For example, MSM software package ExtremeWare V6.1.5 (Build 20) Project
IP_SERV_TECH_REL V1.2.64 is compatible with PoS module software package
ExtremeWare V6.1.5 (Build 20) Project IP_SERV_TECH_REL V1.1.98, but is not compatible
with PoS module software package ExtremeWare V6.1.5 (Build 20) Project
IP_SERV_TECH_REL V2.1.1.
Cables and Connectors
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
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 P3cMi (multimode version) operates in the 1310 nanometer (nm) wavelength
window at a typical maximum cable distance of 2 kilometers (km) or 1.24 miles (mi).
The P12cMi (multimode version) also operates in the 1310 nanometer (nm) wavelength,
but at a typical maximum cable distance of 500 meters (m) or 0.31 (mi). The P3cSi and
P12cSi (single-mode versions) also operate in the 1310 nanometer (nm) wavelength
window, but at a typical maximum cable distance of 15 km or 9.32 (mi). All four
versions of the PoS module use industry-standard duplex SC optical-fiber connectors.
