Cisco MGX 8880 Media Gateway
As shipped, an MGX 8880 chassis could have up to six VXSM-4-155 or VXSM-48T1E1 cards in slots
1 through 6. These slots are covered by the installed RCONs, which currently support VXSM 1:1
redundancy.Up to four RPM-XF cards could go in slots 9 through 12. Or additional VXSM cards could
go in slots 9 through 14 (and 1:1 redundancy would be supported).
The RCON-1TO5-8850 has built-in APS function for slot pairs 1 and 2, 5 and 6 ( upper bay), and 17 and
18, 21 and 22 (lower bay). The RCON has virtual APS backplane function for slot pa irs 3 and 4, and 19
and 20. So there is no need for MGX-APS-CON in these slots.
The RCON provides 1:1 redundancy support for slot pairs 3 and 4, and slot pairs 19 and 20, in
conjunction with the VXSM Redundancy back card. Slots supported by t he RCON-1TO5-8850
connector can support 1:N.
