Installing and setting up CMC
This section provides information about how to install your CMC hardware, establish access to CMC, configure your
management environment to use CMC, and guides you through the tasks for configuring a CMC:
● Set up initial access to CMC.
●
Access CMC through a network.
● Add and configure CMC users.
● Update CMC firmware.
Topics:
• Installing CMC hardware
• Configuring chassis management at server mode
Installing CMC hardware
The CMC is pre-installed on your chassis and hence no installation is required.
Checklist to set up chassis
The following tasks enable you to accurately setup the chassis:
1. The CMC and the management station, where you use your browser, must be on the same network, which is called the
management network. Connect an Ethernet network cable from the port labelled GB1 to the management network.
Management Network: CMC and the iDRAC (on each server) and the network management ports for the switch I/O
module are connected to a common internal network in the PowerEdge FX2/FX2s chassis. This allows the management
network to be isolated from the server data network.
Application Network: Access to the managed servers is accomplished through network connections to the I/O module
(IOM). This allows the application network to be isolated from the management network. It is important to separate this
traffic for uninterrupted access to chassis management.
NOTE:
It is recommended to isolate chassis management from the data network. Due to the potential of traffic on the
data network, the management interfaces on the internal management network can be saturated by traffic intended for
servers. This results in CMC and iDRAC communication delays. These delays may cause unpredictable chassis behavior,
such as CMC displaying iDRAC as offline even when it is up and running, which in turn causes other unwanted behavior.
If physically isolating the management network is impractical, the other option is to separate CMC and iDRAC traffic to a
separate VLAN. CMC and individual iDRAC network interfaces can be configured to use a VLAN.
2. The STK/Gb2 port can also be used for CMC NIC failover. Ensure that the CMC setting is changed from default Stacking
to Redundant to implement NIC failover. For more information, see Configuring Management Port 2
CAUTION:
Connecting the STK/Gb2 port to the management network will have unpredictable results if the
CMC setting is not changed from default Stacking to Redundant, to implement NIC failover. In the default
Stacking mode, cabling the Gb1 and STK/Gb2 ports to the same network (broadcast domain) can cause a
broadcast storm. A broadcast storm can also occur if the CMC setting is changed to Redundant mode, but
the cabling is daisy chained between chassis in the Stacking mode. Ensure that the cabling model matches
the CMC setting for the intended usage.
3. Install the I/O module in the chassis and connect the network cable to the I/O module.
4. Insert the servers in the chassis.
5. Connect the chassis to the power source.
6. To power on the chassis, press the power button or use the following interfaces after completing the task 6. Using the Web
interface, go to Chassis Overview > Power > Control > Power Control Options > Power On System. Click Apply.
