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
Handle the PXM1 front card very carefully to preserve the alignment of the attached disk drive. Do
Caution
not drop or bump the PXM1.
Before using the MGX 8850, verify that the daughter card on the PXM1 corresponds to the uplink
Caution
card type. Serious damage may result if the power is on and these cards are mismatched.
If you accidentally insert a back card for a service module into slot 7, 8, 23, or 24, carefully remove
Note
the back card and check for bent or damaged pins on the backplane and the back card.
