Owners Manual

Create separate chains for the CMCs in the active CMC slot and the second CMC slot.
NOTE: At least one CMC must be installed for the system to power up. If a second, optional CMC module is installed,
failover protection and hot-swap replacement is available. See the latest CMC User's Guide at support.dell.com/
manuals for complete instructions on how to set up and operate the CMC module.
The following figure illustrates the arrangement of cables for four daisy-chained chassis, each with active and standby CMCs.
