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

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

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
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 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.
