Users Guide

If you have one chassis, connect CMC and the standby CMC to the management network. If you have a redundant CMC, use another

network cable and connect the GB CMC port to a second port of the management network.

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.

NOTE: Failure to cable CMC properly in a redundant conguration can cause loss of management and create broadcast storms.

Conguring Initial CMC Network

NOTE: Changing the CMC network settings may disconnect the current network connection.

You can perform the initial network conguration of CMC before or after CMC has an IP address. To congure 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

To congure initial network settings after 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

• CMC Web interface

CMC supports both IPv4 and IPv6 addressing modes. The conguration settings for IPv4 and IPv6 are independent of one another.

Conguring CMC Network Using LCD Panel Interface

NOTE

: The option to congure CMC using the LCD panel is available only until CMC is deployed or the default password is

changed. If the password is not changed, you can continue to use the LCD to reset the congurations of the CMC causing a

possible security risk.

The LCD panel is on the bottom-left corner on the front of the chassis.

To set up a network using the LCD panel interface:

1 Press the chassis power button to turn it on.

The LCD screen displays a series of initialization screens as it powers up. When it is ready, the Language Setup screen is displayed.

2 Select the language using the arrow buttons, press the center button to select the Accept/Yes, and press the center button again.

The Enclosure screen displays the following question: Congure Enclosure?

• Press the center button to continue to CMC Network Settings screen. See step 4.

• To exit the Congure Enclosure menu, select the NO icon and press the center button. See step 9.

3 Press the center button to continue to CMC Network Settings screen.

4 Select the network speed (10Mbps, 100Mbps, Auto (1 Gbps)) using the down arrow button.

The Network Speed setting must match your network conguration for eective network throughput. Setting the Network Speed

lower than the speed of your network conguration increases bandwidth consumption and slows network communication. Determine
