3. Scroll to the Security section, clear the Check for publisher’s certificate revocation checkbox, and click OK.
Downloading Files From CMC With Internet Explorer
When you use Internet Explorer to download files from CMC you may experience problems when the Do not save
encrypted pages to disk option is not enabled.
To enable the Do not save encrypted pages to disk option:
1. Start Internet Explorer.
2. Click Tools
→
Internet Options , then click Advanced.
3. Scroll to the Security section and select Do not save encrypted pages to disk.
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.
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 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.
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
