Chassis policies in Cisco Intersight allow to configure various parameters of the chassis, including IP pool configuration, VLAN settings, SNMP authentication, and SNMP trap settings. A chassis policy can be assigned to any number of chassis profiles to provide a configuration baseline for a chassis.

To launch the Policies Table View, choose Configure > Policies.

The Chassis Policy creation wizard in Cisco Intersight has two pages:

• General—The general page allows to select the organization and enter a name for policy. Optionally, include a short description and tag information to help identify the policy. Tags must be in the key:value format. For example, Org:IT or Site: APJ

• Policy Details—The policy details page has properties that are applicable to UCS Chassis Policies.

Chassis Policies can also be cloned by using the Policy Clone wizard with properties that are similar to the existing policies. The clone policy action is available on both the policies list and detailed views. For more information, see Cloning a Policy.

You can compare up to five policies of the same type from the Policies List View page to identify configuration differences, maintain consistency, and simplify troubleshooting.

To compare policies, select the checkboxes next to the desired policies, click the ellipsis (…) at the top left of the page, and choose Compare. On the Compare side drawer, only the differences between the selected policies are shown by default. To display all parameters, select All from the Display drop-down menu.

Note	You can compare a minimum of two and a maximum of five policies of the same type at a time.

The following list describes the chassis policies that you can configure in Cisco Intersight.

• IMC Access Policy—This policy enables configuration and management of the network by mapping IP pools to the chassis profile. It allows In-Band and Out-of-Band configurations, with association to an IP address from the IP pool. The policy also permits forwarding SNMP traffic over In-Band and Out-of-Band configurations.

• Power Policy—Enables the management of power usage for the chassis. This policy allows to configure the redundancy mode of the Chassis Power Supply Units (PSUs) and allocate power to the chassis. You can view the redundancy health, redundancy mode, input power health, and output power health of the chassis in the properties section of the General tab on the Chassis details view page. For Cisco UCS X9508 Chassis, you can configure Power Save Mode and Dynamic Power Reallocation.

• SNMP Policy—Configures the SNMP settings for sending fault and alert information by SNMP traps from the managed devices. SNMP Users or SNMP Traps configured previously on the managed devices are removed and replaced with users or traps that you configure in this policy. If you have not added any users or traps in the policy, the existing users or traps on the input/output module (IOM) are removed.

• Thermal Policy—Allows to set the value of the Fan Control Mode for the chassis. The Fan Control Mode controls the speed of the chassis fan to maintain optimal server cooling.

IMC Access policy allows to provide a VLAN ID and enables to associate it with an IP address from the selected IP pool.

6. Configure the following parameters:

   Property	Description
   Power Redundancy	It sets the redundancy mode of the chassis power supplies. This mode determines the number of PSUs the chassis keeps as redundant. The various values that can be set for this mode are:
   	Grid— Grid requires two power sources. If one source fails, the surviving power supplies on the other source provides power to the chassis. Not Redundant— Power Manager turns on the minimum number of PSUs required to support chassis power requirement. No redundant PSUs are maintained. N+1— Power Manager turns on the minimum number of PSUs required to support chassis power requirements and one additional PSU for redundancy. Note   N+1 is the default power redundancy mode for the Cisco UCS X9508 chassis, applicable to any Cisco UCS X-Series server or to Cisco UCS X-Series Direct (UCSX-S9108-100G) under the following conditions: When a chassis is being discovered for the first time in a domain. When a previously decommissioned chassis is recommissioned. N+2— Power Manager turns on the minimum number of PSUs required to support chassis power requirements and two additional PSUs for redundancy. Note   This mode is supported only for Cisco-UCSX-9508 chassis.
   Power Save Mode	Enable to place additional PSU capacity in Power Save mode, when the requested power is less than the available power. Note   This property is supported only on the following: Cisco-UCSX-9508 chassis with the minimum Cisco IMC firmware version of 4.2(1d). Cisco-UCSB-5108 chassis with the minimum Cisco IMC firmware version of 4.3(2a).
   Dynamic Power Rebalancing	Enable for dynamically reallocating power for the servers. When enabled, the power will be rebalanced across various chassis components including blades, Fans, IOMs/IFMs, and XFMs. Note   This property is supported only on the following: Cisco-UCSX-9508 chassis with the minimum Cisco IMC firmware version of 4.2(1d). Cisco-UCSB-5108 chassis with the minimum Cisco IMC firmware version of 4.3(2a).
   Extended Power Capacity	Sets the Extended Power Capacity of the Chassis. When this mode is enabled, power is borrowed from the redundant power supplies which increases the power available to the chassis. Note   This property is supported only on Cisco-UCSX-9508 chassis with the minimum Cisco IMC firmware version of 4.2(1d).
   Power Allocation (Watts)	Allows the user to set the maximum power a chassis can consume. The value can range from minimum of system requirement to maximum of available power. Deploying a policy with a Power Allocation of 0 will enable the chassis to utilize all available power according to the Power Redundancy mode. Note   This property is supported only on the following: Cisco-UCSX-9508 chassis with the minimum Cisco IMC firmware version of 4.2(1d). Cisco-UCSB-5108 chassis with the minimum Cisco IMC firmware version of 4.3(2a).

   Note	Note: In Not-redundant mode with Power Save mode enabled, if all the PSUs are powered off either simultaneously or nearly simultaneously, it may result in a service interruption or a reboot of the IOM. For more information, see Consideration for Non-Redundant Power Mode.

5. On the Policy Details page, configure the following parameters:

   Property	Description
   Fan Control Mode Controls the fan speed of the server.
   Balanced	The fan runs faster when needed based on the heat generated by the server. When possible, the fan returns to the minimum required speed. Balanced mode is the default mode. However, it is not recommended for servers equipped with Peripheral Component Interconnect Express (PCIe) cards, as these cards can overheat easily.
   Low Power	The fan runs at slightly lower minimum speeds than the Balanced mode, to consume less power when possible.
   High Power	The fan is kept at higher speed to emphasize performance over power consumption. Note   High Power mode is supported only for UCS X-Series chassis.
   Maximum Power	The fan is always kept at the maximum speed. This option provides the most cooling and consumes most power. Note   Maximum Power mode is supported only for UCS X-Series chassis.
   Acoustic	The fan speed is reduced to reduce noise levels in acoustic-sensitive environments. Note   Acoustic mode is supported only for UCS X-Series chassis.
   Maximum Cooling	The fan runs at full speed to provide maximum cooling for the server, regardless of ambient temperature. Note   Maximum Cooling mode is supported on Cisco UCS C-Series M7 and later servers, running on firmware version 4.3(5.250001) or later.
