8. Provide each iDRAC with an IP address in the CMC Web interface and enable the LAN and IPMI interface.
NOTE: iDRAC LAN interface on some servers are disabled by default.
9. Provide each IO module with an IP address in the CMC Web interface.
10. Connect to each iDRAC through the Web browser and provide final configuration of iDRAC. Default user name is
root and password is calvin .
11. Connect to each IO module through the Web browser and provide final configuration of the IO module.
12. Power on the servers and install the operating system.

Basic CMC Network Connection

For the highest degree of redundancy, connect each available CMC to your management network.
Each CMC has two RJ-45 Ethernet ports, labeled GB (the uplink port) and STK (the stacking or cable consolidation port).
With basic cabling, you connect the GB port to the management network and leave the STK port unused.
CAUTION: Connecting the STK port to the management network can have unpredictable results. Cabling GB and
STK to the same network (broadcast domain) can cause a broadcast storm.

Daisy chain CMC Network Connection

If you have multiple chassis in a rack, you can reduce the number of connections to the management network by daisy-
chaining up to four chassis together. If each of the four chassis contains a redundant CMC, by daisy-chaining you can
reduce the number of management network connections required from eight to two. If each chassis has only one CMC,
you can reduce the connections required from four to one.
When daisy-chaining chassis together, GB is the uplink port and STK is the stacking (cable consolidation) port. Connect
the GB ports to the management network or to the STK port of CMC in a chassis that is closer to the network. You must
connect the STK port only to a GB port further from the chain or network.
Create separate chains for CMCs in the active CMC slot and the second CMC slot.
The following figure illustrates the arrangement of cables for four daisy-chained chassis, each with active and standby
CMCs.
