Power Supply Modes

Cisco MDS 9000 Series Multilayer Switches support different number and capabilities of power supplies. This section describes the power modes that are available on Cisco MDS 9000 Series Multilayer Switches.

Cisco MDS 9710 Multilayer Switches can support up to four power supplies when they have only Cisco MDS 9700 48-Port 32-Gbps Fibre Channel Switching Modules installed on them. By default, the four power supplies are installed in the power supply bays 1 to 4.

You can configure one of the following power modes to use the combined power provided by the installed power supply units (no power redundancy) or to provide power redundancy when there is power loss. We recommend that you configure the full redundancy power mode on your switch for optimal performance.

Combined mode—This mode uses the combined capacity of all the power supplies. In case of power supply failure, the entire switch can be shut down (depending on the power used) causing traffic disruption. This mode is seldom used, except in cases when the switch requires more power.
Input Source (grid) redundancy mode—This mode allocates half of the power supplies to the available category and the other half to the reserve category. You must use different power supplies for the available and reserve categories so that if the power supplies used for the active power fails, the power supplies used for the reserve power can provide power to the switch. If the grid-redundancy mode is lost, the power mode reverts to combined mode.
Power-supply (N+1) redundancy mode—This mode allocates one power supply as reserve to provide power to the switch in case an active power supply fails. The remaining power supplies are allocated for the available category. The reserve power supply must be at least as powerful as each of the power supplies used for the active power.
Full-redundancy mode—This mode is a combination of input-source (grid) and power-supply (N+1) redundancy modes. Similar to the input-source redundancy mode, this mode allocates half of the power supplies to the available category and the remaining power supplies to reserve category. One of the reserve power supplies can alternatively be used to provide power if a power supply used for the active power fails.

For more information on the power supply modes supported on your switch, see the Hardware Installation Guide corresponding to your switch.

Configuration Guidelines for Power Supplies

For information that is specific to the power supplies supported on your switch, see the Hardware Installation Guide corresponding to your switch.

Note

Some Cisco MDS switches support DC and high-voltage DC (HVDC) power supplies. HVDC power supplies support 440 V (higher voltage), whereas DC power supplies support up to 110 or 220 V. Also, HVDC power supplies are efficient in transmitting power over a long distance.
The Cisco MDS 9250i switch has three power supplies whose power supply mode is configured to N+1 mode. Cisco MDS 9250i switch can also be operated with only two power supplies when 1+1 grid redundancy is required. All the other Cisco MDS 9000 switches (excluding Directors) have a nonconfigurable power supply mode set to 1+1 grid redundancy.

A Cisco MDS 9700 Series switch ships with enough power supplies to power a fully populated chassis in the grid-redundant (N+N) mode. For example, depending on your switch's configuration, Cisco MDS 9710 switch may ship with six power supplies, by default, and can power a fully populated chassis in the grid-redundant power-configuration (N+N) mode. All the power supplies are always powering the chassis. However, for managing, reporting, and budgeting the power supplies, Cisco MDS NX-OS supports various configurable power supply modes. One of the features of the power supply modes is to make assumptions, especially in grid configuration, to identify power supplies that are connected to grid A and grid B power whips. For information on connecting power supplies, see the "Product Overview" section in the Cisco MDS 9700 Series Hardware Installation Guide.

The following table provides information about the power supply bays with respect to grid configurations:

Table 1. Cisco MDS 9700 Grid-Slot Location
Cisco MDS Switch	Grid A	Grid B
Cisco MDS 9718	PSU1, PSU2, PSU5, PSU6, PSU9, PSU10, PSU13, PSU14	PSU3, PSU4, PSU7, PSU8, PSU11, PSU12, PSU15, PSU16
Cisco MDS 9710	PSU1, PSU2, PSU5, PSU6	PSU3, PSU4, PSU7, PSU8
Cisco MDS 9706	PSU1, PSU2	PSU3, PSU4

The following is a list of power supply modes supported on Cisco MDS switches:

Note

Changing between power modes is non disruptive and is possible only if there is enough power available in the target mode. If enough power is not available, MDS NX-OS rejects the command with “Insufficient capacity” message.

Ps-redundant mode—The default power supply mode is the ps-redundant mode, which is equivalent to the N+1 redundant mode because this mode is flexible enough to cover the deployments in the most diverse environments. In this mode, N functioning power supplies are used for budgeting, alerting, reporting, and monitoring, and one power supply is used as reserve. The total available power is the sum of capacities of the N power supplies.

In the ps-redundant mode, there is no restriction for the placement of power supplies in the chassis slots. The power supplies need not be placed in grid A or grid B as recommended. Even if the power supplies are placed as recommended in grid A or grid B, MDS NX-OS will not support budgeting, alerting, reporting, and monitoring as per a grid configuration because of the N+1 redundancy mode.

Table 2. ps-redundant Mode
Scenario	Grid A			Grid B			Available Capacity (Watts)	Power Supply Operational Mode
	Power Supply 1 (Watts)	Power Supply 2 (Watts)	Power Supply 5 (Watts)	Power Supply 3 (Watts)	Power Supply 4 (Watts)	Power Supply 7 (Watts)
1	3000	3000	3000	3000	3000	3000	15000	N+1 redundant mode. Available power capacity is the sum of power capacities of all the operational power supply units (PSUs), except one, which is used as reserve.
2	3000	3000	3000	3000	3000	Off	12000
3	3000	3000	3000	3000	Off	Off	9000
4	3000	3000	3000	Off	Off	Off	6000

insrc-redundant mode—If a grid (N+N) mode is required in a chassis for proper budgeting, alerting, reporting, and monitoring purposes, power supplies must be configured, as shown in Table 2 and then the ps-redundant mode should be changed to the insrc-redundant mode.

After the insrc-redundant mode is configured, and if a power supply fails, the power supply mode is changed to combined (nonredundant) mode in relation to the least-populated grid.

When the insrc-redundant mode is configured and a grid fails, the insrc-redundant mode is disabled until the grid is back online. In the meantime, the operational power supply mode is changed to combined (nonredundant) mode and power is used from all the power supplies for budgeting, alerting, reporting, and monitoring.

Table 3. insrc-redundant Mode
Scenario	Grid A			Grid B			Available Capacity (Watts)	Power Supply Operational Mode
	Power Supply 1 (Watts)	Power Supply 2 (Watts)	Power Supply 5 (Watts)	Power Supply 3 (Watts)	Power Supply 4 (Watts)	Power Supply 7 (Watts)
1	3000	3000	3000	3000	3000	3000	9000	3+3 redundant mode. Available capacity is the sum of power capacities of three PSUs, which are used as reserve.
2	3000	3000	3000	3000	3000	Off	6000	Combined (nonredundant) mode because of uneven distribution of PSUs in grids. Available capacity is the sum of power capacities of PSUs of the least populated grid.
3	3000	3000	3000	3000	Off	Off	3000	Combined (nonredundant) mode because of uneven distribution of PSUs in grids. Available capacity is the sum of power capacities of PSUs of the least populated grid.
4	3000	3000	3000	Off	Off	Off	9000	Combined (nonredundant) mode because of the grid B failure.

Redundant mode—Redundant mode is a combination of grid (N+N) and ps-redundant (N+1) modes. If the MDS NX-OS power supply mode is set to redundant mode and if there are an equal number of functioning power supplies in each grid location (grid A and grid B), the operational power supply mode is set to the grid (insrc-redundant) mode. If a grid fails, the operational power supply mode is changed to ps-redundant (N+1) mode. The ps-redundant mode is different from the insrc-redundant mode because a grid failure in insrc-redundant mode defaults to combined (nonredundant) mode.

When configured in redundant mode and if a power supply fails, the power supply mode is changed to combined (nonredundant) mode in relation to the least-populated grid.

Table 4. Redundant Mode
Scenario	Grid A			Grid B			Available Capacity (Watts)	Power Supply Operational Mode
	Power Supply 1 (Watts)	Power Supply 2 (Watts)	Power Supply 5 (Watts)	Power Supply 3 (Watts)	Power Supply 4 (Watts)	Power Supply 7 (Watts)
1	3000	3000	3000	3000	3000	3000	9000	3+3 redundant mode with three PSUs in each grid.
2	3000	3000	3000	3000	3000	Off	6000	Combined (non redundant) mode because of uneven distribution of PSUs in grids. Available capacity is the sum of PSUs of the least-populated grid.
3	3000	3000	3000	3000	Off	Off	3000	Combined (non redundant) mode because of uneven distribution of PSUs in grids. Available capacity is the sum of PSUs of the least populated grid.
4	3000	3000	3000	Off	Off	Off	6000	Power supply mode switched to ps-redundant (N+1) mode because of grid B failure.

Note

When the insrc-redundant or redundant mode is configured, the grid power supply with an unbalanced configuration (that is, 2+4, and so on) results in the power supply mode to change to combined (nonredundant) operational mode and insufficient power may be budgeted. We recommend that you do not use a grid power supply with an unbalanced configuration when the insrc-redundant or redundant mode is configured.

Combined (nonredundant) mode—This has no restrictions on how external power sources are connected to a Cisco MDS 9710 switch. The power that is available to the switch is the sum of all the working power supplies in the chassis. You can change from other power modes to the combined mode without disrupting the traffic.

Table 5. Combined (Nonredundant) Mode
Scenario	Grid A			Grid B			Available Capacity (Watts)	Power Supply Operational Mode
	Power Supply 1 (Watts)	Power Supply 2 (Watts)	Power Supply 5 (Watts)	Power Supply 3 (Watts)	Power Supply 4 (Watts)	Power Supply 7 (Watts)
1	3000	3000	3000	3000	3000	3000	18000	In the combined (non redundant) mode, the position of PSUs do not matter. All PSUs are available for budgeting.
2	3000	3000	3000	3000	3000	Off	15000
3	3000	3000	3000	3000	Off	Off	12000
4	3000	3000	3000	Off	Off	Off	9000

The following table provides information about moving from combined (nonredundant) mode to other power supply modes:

About Module Temperature Monitoring

Built-in automatic sensors are provided in all switches in the Cisco MDS 9000 Family to monitor your switch at all times.

Each module (switching and supervisor) has four sensors: 1 (outlet sensor), 2 (intake sensor), and 3 (onboard sensor). Each sensor has two thresholds (in degrees Celsius): minor and major.

Note

A threshold value of –127 indicates that no thresholds are configured or applicable.

Minor threshold—When a minor threshold is exceeded, a minor alarm occurs and the following action is taken for all four sensors:
- System messages are displayed.
- Call Home alerts are sent (if configured).
- SNMP notifications are sent (if configured).

Major threshold—When a major threshold is exceeded, a major alarm occurs and the following action is taken:

For sensors 1 and 3 (outlet and onboard sensors):

System messages are displayed.

Call Home alerts are sent (if configured).

SNMP notifications are sent (if configured).

For sensor 2 (intake sensor):

If the threshold is exceeded in a switching module, only that module is shut down.

If the threshold is exceeded in an active supervisor module with HA-standby or standby present, only that supervisor module is shut down and the standby supervisor module takes over.

If you do not have a standby supervisor module in your switch, you have an interval of 2 minutes to decrease the temperature. During this interval the software monitors the temperature every five (5) seconds and continuously sends system messages as configured.

Tip

To realize the benefits of these built-in automatic sensors on any switch in the Cisco MDS 9700 Series, we highly recommend that you install dual supervisor modules. If you are using a Cisco MDS 9000 Series switch without dual supervisor modules, we recommend that you immediately replace the fan module if even one fan is not working.

Displaying Module Temperatures

Use the show environment temperature command to display temperature sensors for each module.

This example shows the temperature information.

About Fan Modules

Hot-swappable fan modules (fan trays) are provided in all switches in the Cisco MDS 9000 Series to manage airflow and cooling for the entire switch. Each fan module contains multiple fans to provide redundancy. The switch can continue functioning in the following situations:

One or more fans fail within a fan module—Even with multiple fan failures, switches in the Cisco MDS 9000 Series can continue functioning. When a fan fails within a module, the functioning fans in the module increase their speed to compensate for the failed fan(s).
The fan module is removed for replacement—The fan module is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system. When replacing a failed fan module in a running switch, be sure to replace the new fan module within five minutes.

Note

If one or more fans fail within a fan module, the Fan Status LED turns red. A fan failure could lead to temperature alarms if not corrected immediately.

The fan status is continuously monitored by the Cisco MDS NX-OS software. In case of a fan failure, the following action is taken:

System messages are displayed.
Call Home alerts are sent (if configured).
SNMP notifications are sent (if configured).

Use the show environment fan command to display the fan module status.

This example shows the chassis fan information.

The possible Status field values for a fan module on the Cisco MDS 9700 Series switches are as follows:

If the fan module is operating properly, the status is ok.
If the fan is physically absent, the status is absent.
If the fan is physically present but not working properly, the status is failure.
