Installing and setting up CMC
This section provides information about how to install your CMC hardware, establish access to CMC, congure your management
environment to use CMC, and guides you through the tasks for conguring a CMC:
• Set up initial access to CMC.
• Access CMC through a network.
• Add and congure CMC users.
• Update CMC rmware.
Topics:
• Installing CMC hardware
• Conguring 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 trac for uninterrupted
access to chassis management.
NOTE
: It is recommended to isolate chassis management from the data network. Due to the potential of trac on the data
network, the management interfaces on the internal management network can be saturated by trac intended for servers.
This results in CMC and iDRAC communication delays. These delays may cause unpredictable chassis behavior, such as
CMC displaying iDRAC as oine 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 trac to a
separate VLAN. CMC and individual iDRAC network interfaces can be congured 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 Conguring 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.
