34 Installing and Setting Up the CMC
Allow Animations in Internet Explorer
When transferring files to and from the Web interface, a file transfer icon
spins to show transfer activity. For Internet Explorer, this requires that the
browser be configured to play animations, which is the default setting.
Follow these steps to configure Internet Explorer to play animations:
1
Start Internet Explorer.
2 Click Tools → Internet Options , then click Advanced .
3 Scroll to the Multimedia section and check Play animations in web pages .
Setting Up Initial Access to the CMC
To manage the CMC remotely, connect the CMC to your management
network and then configure the CMC network settings. For information on
how to configure the CMC network settings, see "Configuring the CMC
Network." This initial configuration assigns the TCP/IP networking
parameters that enable access to the CMC.
Once the CMC is connected to the management network, all external access
to the CMC and iDRACs is accomplished through the CMC. Access to the
managed servers, conversely, is accomplished through network connections
to I/O modules (IOMs). This allows the application network to be isolated
from the management network.
NOTE: Dell strongly recommends the best practice of isolating/separating the
management network in the chassis, used by iDRAC and CMC, from your production
network(s). Mixing management and production/application traffic on this
management network could cause congestion/saturation, which will result in CMC
and iDRAC communication delays. The 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. The CMC and individual iDRAC network interfaces can be configured
to use a VLAN with the
racadm setniccfg command. For more information,
see the Dell Chassis Management Controller Administrator Reference Guide.
If you have one chassis, connect the CMC, and the standby CMC if present,
to 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 is connected to the management
