It is strongly recommended to order MPW-1 with original RAD SFPs installed. This
will ensure that prior to shipping, RAD has performed comprehensive functional
quality tests on the entire assembled unit, including the SFP devices. RAD cannot
guarantee full compliance to product specifications for units using non-RAD SFPs.
Note that RAD also offers Fast Ethernet SFPs with copper interfaces (with
RJ-45 connector); however, when copper interfaces are needed, it is more
cost-effective to order MPW-1 with 10/100BASE-TX interfaces.
Ethernet Layer 2 Switch Capabilities
The MPW-1 Ethernet switching subsystem fully complies with the IEEE
802.3/Ethernet V.2 standards, and has full VLAN support. The switching
subsystem has memory-based switch fabric with true non-blocking switching
performance. The subsystem collects a wide range of performance monitoring
parameters, which can be read by management.
The switching subsystem ports are used as follows:
• Three ports are connected via transceivers to the external (ETH 1, ETH 2, and
ETH 3) ports.
• Two Fast Ethernet ports connect to the CL module:
 One Fast Ethernet port is connected to the Ethernet traffic handling
subsystem of the CL modules installed in the Megaplex-4100 (only
CL.1/GbE and CL.1/155GbE modules include an Ethernet traffic handling
section). This connection enables the MPW-1 module to accept Ethernet
traffic from other modules installed in the Megaplex-4100; therefore,
when Megaplex-4100 uses CL.1 or CL.1/155 modules, only Ethernet
traffic from the local MPW-1 Ethernet ports can be processed by the
MPW-1.
 The second Fast Ethernet port is connected to the management handling
section of the CL modules installed in the Megaplex-4100 (this section is
available on all CL modules).
 One management port, connects to the MPW-1 local management
subsystem.
 One port connects to the module TDM cross-connect matrix, through the
Ethernet termination and processing subsystem.
