Fan tray assembly

The Cisco C9610 Series Smart Switches consist of four fan trays. Each fan tray (C9610-FAN) consists of six fans and a connector. If one of the fans is not functioning and you need to replace the fan, you must order a fan tray; individual fans cannot be ordered.

When the system is powered on, all four fan trays must be present, or the system will not initialize.

The fans cool the entire chassis and interface with environmental monitors to trigger alarms when conditions exceed thresholds. Fan trays provide cooling critical for the switch operation, which could otherwise result in the switch being nonoperational or cause permanent damage to modules or components.

The features of a Cisco C9610 fan tray include

  • four fan tray slots in the rear panel of the chassis.
  • six 80 x 80 x 80 mm fans per tray.
  • fan tray modules are installed from the rear to enable front-to-back airflow.
  • optimizes the fan-speed for temperature and pressure, and maintains the minimum fan speeds that the chassis requires, in ambient conditions.

Fan high availability

To ensure high availability, the system responds to fan failures by either minimizing the impact or by compensating and operating at a worst case scenario specification.

  • Boot up: When you power on the switch, all four fan trays must be present, or else, the system will not boot, and the console displays this override message.
    "[HWMSG] FAN_ABSENT: Shutdown now"
  • Runtime: During system runtime if one fan tray is removed from the chassis, the system will still operate; however, the console displays this warning message, and the show hardware led command output will display the system and chassis fan tray status LEDs as red.
    *Aug 12 09:10:43.627 UTC: %CMRP_PFU-2-FAN_POLICY_CRITICAL: Chassis 1 R0/0: 
    cmand: SYSTEM FAN POLICY Critical : MAJOR ALARM - One Fantray Missing!!
    
  • If you remove two or more fan trays from the chassis, a 180 seconds countdown starts. The console displays this override message
    *Jun 16 09:40:07.975: %CMRP_PFU-1-FAN_POLICY_ALERT: R0/0: 
    cmand: SYSTEM FAN POLICY Alert : FAN policy shutdown with reason CRITICAL ALARM: 
    Two or more Fantrays missing!!. Restore working FAN or system will be 
    shutdown in 180 seconds
    
    and the system is shut down after 180 seconds.

Thresholds, alarms, and abnormal acoustic conditions

In normal operating conditions, if no temperature alarms are triggered, the software (if IOS XE software is booted up) controls the fan speed. If the system is in ROMMON mode, the hardware controls the fan speed.
If system temperature alarms are triggered, the software displays an error message indicating that the temperature is high, and fans are operating at higher speed. See the System Management Guide for more information.

If two or more fans fail, you must replace the fan tray within 180 seconds or power down the system. If the temperature exceeds the shutdown threshold, software powers the system down. When the fan trays operate at full speed, increased noise levels can be expected.

The fan trays may operate at 90% of the maximum speed in these circumstances:

  • If two or more fans have failed.
  • If the ASIC thermal sensors hit major, critical, or shutdown thresholds.
  • If one fan tray is removed (with or without additional fan failures).
  • Due to high ambient temperature.

Power supply modules

The switch chassis has eight redundant power supply slots that operate with one to eight power supply modules. The chassis supports field-replaceable AC-input and DC-input power supply modules.

The power supply modules generate 12 VDC output power and distribute it to the line cards and supervisor modules. The power supplies distribute power to all slots using an internal bus-bar based power distribution mechanism. All power supply modules have internal fans and support front-to-rear airflow.

AC power supply modules

Cisco C9610 Series Smart Switches support both 2000W AC and 3000W AC power supply units (PSUs).

The switch is not designed to operate with a combination of 2000W and 3000W PSUs together in a chassis. If a combination of 2000W and 3000W is used, when the chassis is switched on, the following error message is displayed on the console:
*Jan 7 12:07:52.924 IST: %CMRP_PFU-2-PSU_MIX_PWR_CAPACITY: R0/0: cmand: 
Power supplies of mixed power capacity is not a supported configuration. 
This can lead to unstable behavior or system reload, please connect power supplies 
of the same power capacity to avoid any issues.

The 2000W AC is Platinum-rated and meets the Platinum certification standard for energy efficiency. Platinum-based PSUs typically provide around 92% efficacy at 50% load, with only 8% lost as heat.

The 3000W AC power supply module is Titanium-rated, and refers to a power supply that meets the Titanium efficiency standard. This standard ensures minimal energy loss during power conversion, and is at present, the highest efficiency rating available for server power supplies. Titanium-based power supplies typically provide 96% or higher efficiency at 50% load, and up to 94% at full load.

The features of the AC power supply module are

  • self-cooling, with a minimum airflow of 17 cubic feet per minute (CFM) at 100 percent load,
  • a single-phase source AC. Source AC can be out-of-phase between multiple power supplies or multiple AC-power plugs on the same power source because all AC power supply inputs are isolated,
  • a release latch and cord-retention mechanism on the front panel of the module, to avoid accidental removal of the module or the attached power cord, and
  • redundant and combined configuration modes.

A single (non-redundant) or a dual (redundant) power supply configuration, can support these loads.

  • a release latch mechanism on the side of the module, to avoid accidental removal of the module,
  • a DC-input reversal protection such that the unit will survive this condition up to the full input voltage rating, and
  • redundant and combined configuration modes.

A single (non-redundant) or a dual (redundant) power supply configuration supports these loads.

Power supply modes

Cisco C9610 series smart switches offer redundant and combined configuration modes for power supplies. In both modes, the load is equally distributed among the power supplies.

The system load and number of power supply modules installed determine the power level required by the system from each power supply module, and consequently, the suitable power supply mode. For system power budgeting estimates and to determine power supply requirements, use the Cisco Power Calculator.

To configure a power supply mode, enter the power redundancy-mode command in global configuration mode. If you do not configure a mode, the default mode applies. The default mode is combined mode.

Combined mode

The system operates with one to eight power supply modules. The power available to the system is the sum of the power outputs of all the power supply modules in the chassis multiplied by the share ratio. All available power supply modules are active and sharing power, and can operate at up to 100 percent capacity. Additional power supply units operate at 97 percent capacity.

In combined mode, you can use a combination of AC or DC power supplies, provided the AC input voltage is 220V and the power supplies are of equal wattage. However, you cannot combine an AC power supply unit of 110V input with an AC power supply unit of 220V input.

Total combined mode power = P + (N-1) * (P-60)

  • where P is the power output of one of the power supply units and N is the number of power supply modules used.
  • and 60W is the power wastage for every additional PSU, other than the first one; regardless of the PSU capacity or input voltage.
 Note

In case of a failure in combined mode, each operational power supply increases its output. If the output power does not meet the system requirements, all the operational power supply modules may be overloaded and go into overcurrent shutdown. All system power is then lost.

This table provides details about the power output in combined mode.

Redundant N+1 mode

In a redundant configuration, a given power supply module can either be active, or in a standby mode. You can configure either N+1 mode or N+N mode, where N is the number of active power supply modules.

In N+1 mode, N is the number of active power supply modules and +1 is the power supply module configured as the standby module.

When you configure the switch with N+1 redundancy, the Cisco IOS XE software ensures that there is a standby power supply available, and that sufficient power is available with the active power supply modules (N). All the power supplies including the active and standby shares the load equally. However, with a standby power supply installed, the system ensures that the additional output power available with a standby is always reserved for use in case of a failure. If the power supply mode is set to redundant and the total active output power is not sufficient to meet the power requirements, the switch will not enter redundant mode.

You can use a combination of AC or DC power supplies provided the AC input voltage is 220V and the power supplies are of equal wattage. However, you cannot combine an AC power supply unit of 110V input with a AC power supply unit of 220V input.
