The chassis connectivity policy determines whether a specific chassis is included in a fabric port channel after chassis discovery. This policy is helpful for users who want to configure one or more chassis differently from what is specified in the global chassis discovery policy. The chassis connectivity policy also allows for different connectivity modes per fabric interconnect, further expanding the level of control offered with regards to chassis connectivity.

By default, the chassis connectivity policy is set to global. This means that connectivity control is configured when the chassis is newly discovered, using the settings configured in the chassis discovery policy. Once the chassis is discovered, the chassis connectivity policy controls whether the connectivity control is set to none or port channel.

Chassis /FEX Discovery

The chassis discovery policy determines how the system reacts when you add a new chassis. The Cisco UCS Manager uses the settings in the chassis discovery policy to determine the minimum threshold for the number of links between the chassis and the fabric interconnect and whether to group links from the IOM to the fabric interconnect in a fabric port channel. In a Cisco UCS Mini setup, chassis discovery policy is supported only on the extended chassis.

The Cisco UCS Manager cannot discover any chassis that is wired for fewer links than are configured in the chassis/FEX discovery policy. For example, if the chassis/FEX discovery policy is configured for four links, the Cisco UCS Manager cannot discover any chassis that is wired for one link or two links. Reacknowledgement of the chassis resolves this issue.

Rack Server Discovery Policy

The rack server discovery policy determines how the system reacts when you add a new rack-mount server. The Cisco UCS Manager uses the settings in the rack server discovery policy to determine whether any data on the hard disks is scrubbed and whether server discovery occurs immediately or needs to wait for explicit user acknowledgment.

The Cisco UCS Manager cannot discover any rack-mount server that has not been correctly cabled and connected to the fabric interconnects. The steps to configure rack server discovery are as follows:

Step 1. In the Navigation pane, click Equipment.

Step 2. Click the Equipment node. In the Work pane, click the Policies tab.

Step 3. Click the Global Policies subtab.

Step 4. In the Rack Server Discovery Policy area, specify the action that you want to occur when a new rack server is added and specify the scrub policy. Then click Save Changes.

Initial Server Setup for Standalone UCS C-Series

Use the following procedure to perform initial setup on a UCS C-Series server:

Step 1. Power up the server. Wait for approximately two minutes to let the server boot in standby power during the first bootup. You can verify power status by looking at the Power Status LED:

Off: There is no AC power present in the server.

Amber: The server is in standby power mode. Power is supplied only to the CIMC and some motherboard functions.

Green: The server is in main power mode. Power is supplied to all server components.

Note

Verify server power requirements because some servers (UCS C-240, for example) require 220V instead of 110V.

Note

During bootup, the server beeps once for each USB device that is attached to the server. Even if no external USB devices are attached, there is a short beep for each virtual USB device, such as a virtual floppy drive, CD/DVD drive, keyboard, or mouse. A beep is also emitted if a USB device is hot-plugged or hot-unplugged during the BIOS power-on self-test (POST), or while you are accessing the BIOS Setup utility or the EFI shell.

Step 2. Connect a USB keyboard and VGA monitor by using the supplied Kernel-based Virtual Machine (KVM) cable connected to the KVM connector on the front panel. You can use the VGA and USB ports on the rear panel. However, you cannot use the front-panel VGA and the rear-panel VGA at the same time. If you are connected to one VGA connector and you then connect a video device to the other connector, the first VGA connector is disabled.

Step 3. Open the Cisco IMC Configuration Utility as follows:

Press the Power button to boot the server. Watch for the prompt to press F8.

During bootup, press F8 when prompted to open the Cisco IMC Configuration Utility, as shown in Figure 12-36.

Note

The first time that you enter the Cisco IMC Configuration Utility, you are prompted to change the default password. The default password is password.
