Installing and Setting Up the CMC 41
Follow these steps to daisy-chain up to four chassis:
1
Connect the GB1 port of the primary CMC in the first chassis to the
management network.
2 Connect the GB1 port of the primary CMC in the second chassis to the
GB2 port of the primary CMC in the first chassis.
3 If you have a third chassis, connect the GB1 port of its primary CMC to
the GB2 port of the primary CMC in the second chassis.
4 If you have a fourth chassis, connect the GB1 port of its primary CMC to
the GB2 port of the third chassis.
5 If you have redundant CMCs in the chassis, connect them using the same
pattern.
NOTICE: The GB2 port on any CMC must never be connected to the management
network. It can only be connected to the GB1 port on another chassis. Connecting a
GB2 port to the management network can disrupt the network.
NOTE: Never connect a primary CMC to a secondary CMC.
NOTE: Resetting a CMC whose GB2 port is chained to another CMC can disrupt the
network for CMCs later in the chain. The "child" CMCs may log messages indicating
that the network link has been lost and they may fail over to their redundant CMCs.
Configuring the CMC Network
NOTICE: 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 via iKVM
• Remote RACADM
• The CMC Web interface
