The CMC has two Ethernet ports. "Gb1" is used to connect to the external
management network. "Stack" allows CMCs in adjacent enclosures to be
daisy-chained. A 24-port Ethernet switch provides internal 100-Mb
communication with the blades, I/O modules, optional iKVM, and
optional second, redundant CMC, and provides a 10/100/1000-Mb
connection to the external management network.
NOTE:
The 24-port Ethernet switch is reserved for internal communication
between the iDRAC on the blades to the CMC, then to the external
management network.
A second, optional CMC can be installed for hot-plug failover redundancy.
• An enclosure control panel that includes an LCD display which provides
current infrastructure and blade information, and error reporting.
• An optional Avocent integrated Keyboard, Video and Mouse (iKVM)
module, which includes the following features:
– The iKVM maintains all blade connections as input is switched from
each blade.
– Local iKVM access can be remotely disabled on a per blade basis via
the iDRAC user interface.
– One VGA connector.
– Two USB ports for keyboard and mouse connections.
NOTE:
USB functionality is contingent on the connection of a video interface,
such as a monitor cable.
– An RJ-45 ACI port for tiering with external Dell and Avocent analog
KVM and KVM over IP switches with ARI ports. The ACI connection
takes precedence over the rear panel KVM ports.
– The iKVM can also be accessed from the control panel in the front of
the enclosure. Either front or rear KVM functionality is supported
(simultaneous functionality is not supported).
NOTE:
The front iKVM is enabled by default if contention exists between the
front and rear iKVM ports. Front iKVM access can be disabled via the CMC
user interface.
