Planning Standalone and Redundant Card Configurations
Planning Standalone and Redundant Card Configurations
A PXM card or service module operates in either standalone mode or r edundant mode, depending on the
card type, the other cards in the switch, and the configuration applied to that card. The following
subsections provide planning guidelines for installing cards that will operated in standalone and
redundant configurations.

1. MPSM-8-T1E1 can replace or serve as a standby card for this card type.
2. When bulk distribution is used with redundant PXM1Es and SRMEs or SRME/Bs, intercard APS line redundancy (through
the SRME) is supported.
3. 1:1 redundancy supported only with the SCSI2-2HSSI/B back card and a FRSM-HS1/B HSSI Y-cable. 1:1 redundancy is not
supported in slots that use the 12IN1-8S back card.
4. SRME/B supports T3, SONET, and SDH interfaces. Intercard APS is available only on SONET and SDH interfaces.
5. VXSM intracard APS is supported only on 1:1 redundant card installations in MGX 8880 slots 3 and 4.
