Single Slot Expansion Management Module
This device, used in conjunction with the CPSMM-200 (or CPSMM-120 when inserted in the same chassis) management module, allows the user to manage up to eight Point System chassis together in a "virtual cabinet". This brings the total number of media converters managed by a single IP to 143. The CPSMM-210 has two RJ-45 ports ("in" and "out") used for stacking multiple Point System chassis. The CPSMM-210 incorporates a self-healing bus so that the failure of any one module will not effect remaining modules in the stack.

The CPSMM-210 should be used when the user has a requirement to stack multiple chassis. The CPSMM-210 also has a FCC/CISPR Class B rating for deployment in residential applications.
