4.19.1 Slot Compatibility by Cross-Connect Card
You can install MRC-2.5G-4 cards in Slots 1 through 6 and 12 through 17 with an XCVT, XC10G, or
XC-VXC-10G.
Note The MRC-2.5G-4 card supports an errorless software-initiated cross-connect card switch when used in
a shelf equipped with XC-VXC-10G and TCC2/TCC2P cards.
The maximum bandwidth of the MRC-2.5G-4 card is determined by the cross-connect card, as shown in
Table 4-22.
4.19.2 Ports and Line Rates
Total MRC-2.5G-4 card bandwidth cannot exceed OC-48/STM-16, so there are some limitati ons on
which SFP ports can be used as OC-3/STM-1, OC-12/STM-4, and OC-48/STM-16.
The following rules apply for port bandwidth allocation:
STS-12 maximum backplane bandwidth
Port 1 is the only port that is usable as an OC-12/STM-4. If Port 1 is used as an OC-12/STM -4,
all other ports are disabled.
Each of the four ports can be used as OC-3/STM-1.
STS-48 maximum backplane bandwidth
Port 1 is the only port that is usable as an OC-48/STM-16. If Port 1 is used as an
OC-48/STM-16, all other ports are disabled.
Mixed OC-3/STM-1 and OC-12/STM-4 configurations are supported. All possible
permutations are not covered in this reference section.
