When transferring files to and from the Web interface, a file transfer icon spins to show transfer activity. While using Internet
Explorer, you must configure the the browser to play animations.
To configure Internet Explorer to play animations:
1. Start Internet Explorer.
2. Click Tools > Internet Options > Advanced.
3. Scroll to the Multimedia section and select the Play animations in web pages option.
Setting Up Initial Access to CMC
To manage CMC remotely, connect CMC to your management network and then configure CMC network settings.
NOTE: To manage the M1000e solution, it must be connected to your management network.
For information to configure CMC network settings, see Configuring Initial CMC Network. This initial configuration assigns the
TCP/IP networking parameters that enable access to CMC.
Ensure that CMC and iDRAC on each server and the network management ports for all switch I/O Modules are connected to
a common internal network in the M1000e chassis. This allows the management network to be isolated from the server data
network. It is important to separate this traffic for uninterrupted access to chassis management.
CMC is connected to the management network. All external access to CMC and iDRACs is accomplished through 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.
It is recommended to isolate chassis management from the data network. Dell cannot support or guarantee uptime of a chassis
that is improperly integrated into your environment. 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.
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 configuration can cause loss of management and create broadcast
storms.

NOTE: Changing the CMC network settings may disconnect the current network connection.
You can perform the initial network configuration of CMC before or after CMC has an IP address. To configure CMC’s initial
network settings before you have an IP address, you can use either of the following interfaces:
