What CMU Models Are Applicable to the CloudEngine 12800 Series Switches?

The CE12804S/CE12808S chassis do not have independent CMUs, and their monitoring modules are integrated on the MPUs.

CMUs of the CE12804/CE12808/CE12812/CE12816 chassis include CE-CMUA and CE-CMUB. They differ in the following ways:

  • They monitor and manage different quantities of power modules and fan modules.
  • They are applicable to different chassis models and installed in CMU slots with different slot IDs.

Table 22-19 describes differences between the CE-CMUA and CE-CMUB
