Certificate Revocation List Fetching

If your CMC has no access to the Internet, disable the certificate revocation list (CRL) fetching feature in Internet Explorer. This
feature tests whether a server such as the CMC web server uses a certificate that is on a list of revoked certificates retrieved from
the Internet. If the Internet is inaccessible, this feature can cause delays of several seconds when you access the CMC using the
browser or with a command line interface such as remote RACADM.
To disable CRL fetching:
1. Start Internet Explorer.
2. Click Tools → Internet Options, and then click Advanced.
3. Go to the Security section, clear the Check for publisher's certificate revocation option, and then click OK.

Downloading Files From CMC With Internet Explorer

When you use Internet Explorer to download files from the 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 → Advanced.
3. In the Security section, select the Do not save encrypted pages to disk option.

Enabling Animations In Internet Explorer

When transferring files to and from the web interface, a file transfer icon spins to show transfer activity. While using Internet
explorer, you have to configure the browser to play animations.
To configure Internet Explorer to play animations:
1. Start Internet Explorer.
2. Click Tools → Internet Options → Advanced.
3. Go to the Multimedia section, and then select the Play animations in web pages option.

Setting Up Initial Access to CMC

To remotely manage the CMC, connect the CMC to your management network, and then configure the CMC network settings.
NOTE: To manage the PowerEdge VRTX solution, it must be connected to your management network.
For information about configuring CMC network settings, see
TCP/IP networking parameters that enable access to CMC.
CMC and iDRAC on each server and the network management ports for the switch I/O module are connected to a common
integrated network in the PowerEdge VRTX 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 achieved through CMC. Access to the
managed servers, conversely, 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 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.
