Table 2-16 reports the SMP cable usage for the four-enclosure scenario.
Table 2-16 SMP cable four-enclosures scenario
When adding CEC enclosures in an MES upgrade, SMP cables will likely have to be added
depending on how many enclosures are being added.
Adding more than one CEC enclosure to an existing configuration can be accomplished with
a hot-add if the enclosures are added one at a time. The other option is to bring the entire
system down and add all the additional enclosures at the same time. Depending on whether
the hot-add option is desired, certain SMP cable features might or might not be necessary.
