For additional information about enhancements to the RPM/B and minimum firmware and IOS requirements,
refer to Product Bulletin, No. 984. RPM−PRs do not work with the MGX−RJ45−4E. RPM−PRs require a
MGX−RJ45−4E/B. The MGX−RJ45−4E/B works with the RPM/B and RPM−PR.

Characteristics of the RPM (RPM/A)
You can identify an RPM by the module's ATMizer chip. Look at the top of the card (when the card is held
upright) for the column identifier L. In the example provided, the identifiers are two ATMizer chips from LSI.
The original RPM has a chip labeled ATMizer−LX60. The chips below these (in an L formation) have a logo
from Digital on them. The chips in the L formation are indicated by circles in this picture:
