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

4.19.2 Ports and Line Rates
Total MRC-2.5G-4 card bandwidth cannot exceed OC-48/STM-16, so there are some limitations 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:
