Installing and Setting Up the CMC 43
If you have more than one chassis you can choose between the basic
connection, where each CMC is connected to the management network, or a
daisy-chained chassis connection, where the chassis are connected in series
and only one CMC is connected to the management network. The basic
connection type uses more ports on the management network and provides
greater redundancy. The daisy-chain connection type uses fewer ports on the
management network but introduces dependencies between CMCs, reducing
the redundancy of the system.
For more information on daisy-chained connection, see "Daisy-chain CMC
Network Connection" on page 33."
NOTE: Failure to cable the CMC properly in a redundant configuration can cause
loss of management and create broadcast storms.
Configuring the CMC Network
NOTE: Changing your CMC Network settings may disconnect your current
network connection.
You can perform the initial network configuration of the CMC before or after
the CMC has an IP address. If you configure the CMC’s initial network settings
before you have an IP address, you can use either of the following interfaces:
• The LCD panel on the front of the chassis
• Dell CMC serial console
If you configure initial network settings after the CMC has an IP address,
you can use any of the following interfaces:
• Command line interfaces (CLIs) such as a serial console, Telnet, SSH,
or the Dell CMC Console through iKVM
• Remote RACADM
•The CMC Web interface
