Processor Switching Module

The PXM1 card set consists of the PXM1 front card, the PXM1 User Interface back card (PXM1-UI or PXM-UI-S3), and various uplink back cards that can serve as either a trunk or a UNI.

For physical details of PXM1 cards, see Appendix A, “Technical Specifications.”

Caution Handle the PXM1 front card very carefully to preserve the alignment of the attached disk drive. Do not drop or bump the PXM1.

Caution Before using the 8230, verify that the daughter card on the PXM1 corresponds to the uplink card type. Serious damage may result if the power is on and these cards are mismatched.

Note The PXM1 processor module for the MGX 8230 is identical to the PXM1 for the MGX 8250.
