Connecting the MIMO/Protection Splitters and Protection
Signaling Cable
Each splitter has three ports:
•
System plug (“Sys”) –
The system plug should be connected to the PTP 8
20C’s management
port.
•
Man
agement port (“Mng”) –
A standard CAT5E cable should be connected to the splitter’s
management port in order to utilize out-of-band (external) management.
Note
Even for systems that use in-band management, initial configuration of a 4x4 MIMO
and any HSB protection configuration must be performed manually using out-of-band
management.
•
MIMO/Protection signaling port (“MIMO/Prot”) –
A MIMO/Protection signaling cross cable, as
described above, should be connected between this port and the other “MIMO/Prot”
port of
the second splitter on the mate PTP 820C unit.
•
The following figure demonstrates a 4x4 MIMO configuration in which both PTP 820C units are
connected to an external management station and to each other, using two splitters.
