The Cisco UCS C-Series Rack-Mount Server ships with two major software systems installed.
CIMC is a separate management module built into the motherboard. A dedicated ARM-based
processor, separate from the main server CPU, runs the CIMC firmware. The system ships with a running version of the CIMC firmware. You can update the CIMC firmware, but no initial installation is needed.
The main server CPU runs an OS such as Windows or
Linux. The server ships with a pre-installed OS, but you can install a different OS using the DVD drive
or over the network. You can use CIMC to install the
new OS using the KVM console and vMedia.
The CIMC is the management service for the C-Series servers. CIMC runs within the server.
The CIMC management service is used only when the server is operating in Standalone Mode. If your C-Series server is integrated into a UCS system, you must manage it using UCS Manager. For information about using UCS Manager, see the configuration guides listed in the Cisco UCS B-Series Servers Documentation Roadmap at http://www.cisco.com/go/unifiedcomputing/b-series-doc.
You can use a web-based GUI or SSH-based CLI to access, configure, administer, and monitor the server. Almost all tasks can be performed in either interface, and the results of tasks performed in one interface are displayed in another. However, you cannot do the following:
Use CIMC GUI to invoke CIMC CLI
View a command that has been invoked through CIMC CLI in CIMC GUI
Generate CIMC CLI output from CIMC GUI
Tasks You Can Perform in CIMC
You can use CIMC to perform the following server management tasks:
Power on, power off, power cycle, reset and shut down the server
Toggle the locator LED
Configure the server boot order
View server properties and sensors
Manage remote presence
Create and manage local user accounts, and enable remote user authentication through Active Directory
Configure network-related settings, including NIC properties, IPv4, VLANs, and network security
Configure communication services, including HTTP, SSH, and IPMI Over LAN
Configure platform event filters
Update CIMC firmware
Monitor faults, alarms, and server status
No Operating System or Application Provisioning or Management
CIMC provisions servers, and as a result, exists below the operating system on a server. Therefore, you cannot use it to provision or manage operating systems or applications on servers. For example, you cannot do the following:
Deploy an OS, such as Windows or Linux
Deploy patches for software, such as an OS or an application
Install base software components, such as anti-virus software, monitoring agents, or backup clients
Install software applications, such as databases, application server software, or web servers
Perform operator actions, including restarting an Oracle database, restarting printer queues, or handling non-CIMC user accounts
Configure or manage external storage on the SAN or NAS storage
Overview of the CIMC User Interface
The CIMC user interface is a web-based management interface for Cisco C-Series servers. You can launch the CIMC user interface and
manage the server from any remote host that meets the following minimum requirements:
Java 1.6 or later
HTTP and HTTPS enabled
Adobe Flash Player 10 or later
In case you lose or forget the password that you use to log in to CIMC, see the password recovery instructions in the Cisco UCS C-Series server installation and service guide for your server.
